Keenan M, Wojcik S, Clemency BM, Marraffa J. Does Mixing Activated Charcoal With Cola Improve Tolerability Without Affecting Pharmacokinetics? A Randomized Controlled Crossover Trial. J Emerg Nurs 2024:S0099-1767(24)00077-1. [PMID: 38583171 DOI: 10.1016/j.jen.2024.03.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Revised: 02/29/2024] [Accepted: 03/05/2024] [Indexed: 04/09/2024]
Abstract
INTRODUCTION Activated charcoal is the most common form of gastrointestinal decontamination used for the poisoned patient. One limitation to its use is patient tolerability due to palatability. Some recommend mixing activated charcoal with cola to improve palatability. An important question is whether mixing activated charcoal with cola affects the ability of the activated charcoal to adsorb xenobiotic. METHODS This was a prospective randomized controlled crossover trial. Five healthy adults aged 18 to 40 years were recruited. Participants received 45 mg/kg acetaminophen rounded down to the nearest whole tablet. One hour later, they were randomized to receive 50 g of an activated charcoal-water premixture alone or mixed with cola. Acetaminophen levels were collected. The area under the curve of acetaminophen concentrations over time was measured as a marker for degree of absorption. Participants also completed an appeal questionnaire in which they rated the activated charcoal preparations. Participants would then return after at least 7 days to repeat the study with the other activated charcoal preparation. RESULTS Four male participants and 1 female participant were recruited. There was no statistical difference in preference score for activated charcoal alone versus the cola-activated charcoal mixture. There was no statistical difference in the area under the curve of acetaminophen concentrations over time between activated charcoal alone and the cola-activated charcoal mixture. Of note, the study is limited by the small sample size, limiting its statistical power. DISCUSSION The absorption of acetaminophen in an overdose model is no different when participants received activated charcoal alone or a cola-activated charcoal mixture as suggested by area under the curve. In this small study, there was no difference in preference for activated charcoal alone or a cola-activated charcoal mixture across a range of palatability questions. On an individual level, some participants preferred the activated charcoal-cola mixture, and some preferred the activated charcoal alone.

Abstract
INTRODUCTION Metformin is a biguanide used to manage patients with type 2 diabetes mellitus. However, metabolic acidosis with an elevated lactate concentration and death caused by metformin overdoses are toxicological concerns. Although activated charcoal has been widely used for gastrointestinal decontamination in cases of acute poisoning, there is no evidence regarding its efficacy in treating metformin overdoses. We therefore evaluated the adsorptive capacity of activated charcoal for metformin in vitro. METHODS Activated charcoal (specific surface area: 1,080 m2/g) mixed with various concentrations of metformin solution was dissolved in simulated gastric and intestinal fluids at 37° Celsius. The suspension was then filtered and the metformin concentration in the filtrate was determined using high-performance liquid chromatography. The maximum adsorptive capacity for metformin was calculated using the Langmuir adsorption isotherm equation. RESULTS The amount of metformin adsorbed per gram of activated charcoal ranged from 0.7 to 8.1 mg/g at pH 1.2, and from 8.4 to 48.2 mg/g at pH 6.8. The corresponding maximum adsorptive capacities were 10.6 mg/g and 55.9 mg/g respectively. DISCUSSION The maximum adsorptive capacity of activated charcoal for metformin was similar to that of its capacity for other poorly adsorbed substances. This is likely because metformin is water-soluble and has high polarity-factors that correlate with poor adsorption on activated charcoal. CONCLUSIONS The maximum adsorption of metformin by activated charcoal was low. Therefore, activated charcoal may not be effective for treating patients with metformin overdose.

Abstract
Acute intoxications and poisonings are a relevant cause for ICU admission of critically ill patients. This study aimed to determine the characteristics of intoxicated patients in a tertiary center medical ICU in Austria over time and to investigate parameters associated with ICU mortality. This study was a retrospective data analysis including adult ICU patients from the years 2007 to 2021. In addition to ICU documentation, pre-hospital, and emergency department documents as well as autopsy reports were utilized. In an exploratory subanalysis, we compared these findings to a historical dataset from our facility from 1992 to 1996. We identified 581 cases admitted to the medical ICU because of acute poisoning (2007-2021), of which 45% were female and 46.6% were mixed intoxications. Suicidal intent was the primary cause of intoxication (48.2%) and ICU length of stay was median 1.2 days. The majority of deceased patients received pre-hospital mechanical CPR. Primary and secondary poison/toxin removal modalities were used in 29.9% and 11.7% of cases, whereas antidotes were administered in 54.4%. Comparing the data with a historical cohort (n = 168), we found a shift in primary detoxification away from gastric lavage and an increase in alternative secondary poison/toxin removal techniques. The ICU mortality was 4.1% and 4.2% in the present and historic cohort, respectively. Pre-existing psychiatric illnesses increased from 49% in the historic to 69% in the present cohort. Psychiatric illness predisposes patients to severe intoxications necessitating ICU care, thus increasing prevention measures seems warranted. Females did present with a different spectrum of intoxications compared to males. ICU mortality remained low over time and most deceased patients had a grim prognosis already on ICU arrival.

Abstract
Acute poisonings are a global public health problem, which implies costs and disease burden for society. In Colombia, there is a significant underreporting of data on acute poisoning and data gaps on the toxicological profile of the population. This study aims to identify the epidemiology of acute poisoning in a high-complexity hospital in southwestern Colombia. A descriptive study with retrospective data collection was performed. The variables were expressed through the measure of central tendency and dispersion. Categorical variables were described in proportions. A total of 406 patients were included. The median age was 31 years (IQR 23-48), 56.2% were male, and only 19.2% had a history of mental illness. Suicidal intent represented 58.8% of the cases, and the most frequent route of exposure was the oral route (81.6%). The most prevalent groups of substances were pesticides (34.2%) and medicines (32%). The most common etiological agent was organophosphates (16.5%). Cholinergic toxidrome was the most common. The average stay in the ICU was 4.5 days (± 4.8), and the mortality was 4.2%. The principal causes of acute poisoning were drugs and pesticides, with a predominant etiology of organophosphates and depressants of the central nervous system. There was a significant predominance of young male patients with suicidal intent, low mental disorders, elevated unemployment rate, and similar mortality reported in other studies. This study improves the knowledge about acute poisoning in southwestern Colombian to carry out multicenter analytic studies.

Abstract
Background There are significant disparities in the burden of disease due to poisoning between children in low- and high-income countries (HICs). However, there is limited data on the impact of increasing pharmaceutical access in low income countries (LICs) and low-middle income countries (LMICs) on the epidemiology of and risk factors associated with poisoning in children in these settings. Furthermore, while strategies in HICs have effectively reduced the burden of disease due to poisonings in children, there is limited information regarding the efficacy of these interventions in LICs/LMICs. Methods We conducted a systematic review in eight databases for literature published between January 2000 to April 2022 to evaluate the epidemiology and risk factors associated with poisonings due to pharmaceuticals and effective strategies to prevent and manage them in children in LICs/LMICs. From 16 061 retrieved articles, 41 were included in the final analysis. Results Pharmaceuticals were a common cause of poisoning in children in LICs/LMICs, occurring in between 12.4% and 72.36% of cases. Major risk factors were unsafe medication storage and inadequate caregiver knowledge. Delayed access to care and younger age were associated with increased mortality. Prevention strategies that included education demonstrated improvements in knowledge; however, their impact on incidence and mortality was unclear. Management strategies detailed individual patient care interventions, most commonly gastric lavage and activated charcoal. Meanwhile, delayed presentation, limited provider knowledge, and inadequate laboratory resources to support therapeutic monitoring hindered optimal management. Conclusions The combination of educational interventions for prevention, along with regulatory processes to maximise medication storage and formulation safety, could be effective in reducing the burden of poisoning in LICs/LMICs. The development of national or regional protocols for the management of common medication poisonings, augmented by the development of poison control centers and expansion of laboratory access in facilities may help reduce the morbidity and mortality associated with pharmaceutical poisonings in children in LICs/LMICs. Further evidence regarding contextual factors, risk and benefit profiles, the pattern of poisoning, and the impact of preventive and treatment interventions specific to LICs/LMICs is needed to better refine recommendations in these settings.

Abstract
Zinc phosphide is a rodenticide that is used in agricultural, urban and industrial environments in México. After ingestion, it reacts with hydrochloric acid, hydrolyzing into phosphine. It causes cellular hypoxia via mitochondrial toxicity, resulting in multiple organ dysfunction and death. There is no antidote or specific treatment for zinc phosphide toxicity. We present the case of a 45-year-old female who ingested zinc phosphide with suicidal intent. On arrival at the emergency department, she had multisystemic disorders. Supportive care, decontamination and antidotal therapy were initiated. Subsequently, she evolved to clinical improvement with a resolution of the biochemical abnormalities of tissue hypoperfusion. She was discharged on day 7 without complications. In this review, we provide updated therapeutic options and discuss their specific pathophysiological basis.

Abstract
This work aimed to identify variables associated with increased risk of outcome severity as well as to describe clinical manifestations/symptoms and management of pesticide-related cases reported to a poison center in Brazil. An increased risk of more severe outcomes was observed when exposures occurred in rural areas, involved suicide attempts and moderately to extremely hazardous pesticides. Clinical manifestations with higher frequencies included vomiting, nausea, sialorrhea, headache, miosis and sweating. From the treatment initially applied to the patient, 51.91% encompassed gastric lavage, but this procedure was only recommended in 20.01% of cases by the CIATox. Identifying risk factors associated with poor outcome, describing clinical manifestations, and contrasting initial treatment measures adopted against those recommended by the Poison Center can help determine diagnosis, prognosis and ensure appropriate clinical interventions are used in cases of pesticide poisoning.

Abstract
OBJECTIVE To describe the clinical signs and outcome following ivermectin overdose in a bearded dragon. This case also describes the novel use of intravenous lipid emulsion (ILE) as a rescue therapy in reptiles, as well as the use of aggressive gastrointestinal decontamination. CASE SUMMARY A 4-year-old female intact bearded dragon (Pogona vitticeps) (0.6 kg) was admitted to the ICU at a specialty hospital following accidental overdose of 40 mg (66.7 mg/kg) of ivermectin enterally. The patient was physically inverted to allow passive reflux of the medication, then sedated for gastric lavage. A 20% ILE was administered intravenously due to the high risk for fatality. Additional treatments included 2 doses of activated charcoal, as well as SC fluids, enteral nutrition, and sucralfate. The patient was profoundly sedate until day 4 when mild improvements in mentation were noted. The patient started ambulating on its own on day 6 and was discharged from the hospital on day 13. The patient was alive 720 days postdischarge. NEW OR UNIQUE INFORMATION PROVIDED This is the first case report describing the events following ivermectin overdose and the use of ILE therapy and activated charcoal in a bearded dragon. These therapies were tolerated with no adverse effects noted in this patient. This report provides evidence that complete recovery from ivermectin overdose is possible.

Abstract
Oral activated charcoal (OAC), a potent adsorbent with no systemic absorption, has been used for centuries to treat poisoning. Recent studies have suggested its potential efficacy in protecting the colonic microbiota against detrimental effects of antibiotics. In a dose-finding safety and feasibility clinical trial, 12 healthy volunteers not receiving antibiotics drank 4 different preparations made of 2 possible OAC doses (12 or 25 grams) mixed in 2 possible solutions (water or apple juice), 3 days a week for 2 weeks. Pre- and post-OAC stool samples underwent 16S rRNA gene sequencing and exact amplicon sequence variants were used to characterize the colonic microbiota. The preferred preparation was 12 grams of OAC in apple juice, with excellent safety and tolerability. OAC did not influence the gut microbiota in our healthy volunteers. These findings provide the critical preliminary data for future trials of OAC in patients receiving antibiotics.

Abstract
One of the raw forms of graphite is activated charcoal which has an extensive surface area allowing for the adsorption of a wide range of chemicals. It possesses the strongest physical adsorption forces of the available materials, as well as the largest volume of adsorbing porosity. Activated charcoal acts as an adsorbent, collecting and storing substances in the gastrointestinal tract, reducing or blocking absorption in the bloodstream. The ingested toxins interact with charcoal by recycling toxins in the intestinal cavity. In cases where the drug has not been absorbed from the abdominal system, it is recirculated through the liver and intestines or by means of passive diffusion or active secretion. The article aims to review the most recent advances in the use of the activated charcoal, including the dose, how charcoal acts in the body, the mechanism of action, administration, contraindications, as well as the impact of various factors on the adsorption process. In addition, we also discussed numerous medical applications of activated charcoal.

Abstract
BACKGROUND Questions on poisoning by plants are a common reason for inquiries to poison information centers (PIC). Over the years 2011-2020, plant poisoning was the subject of 15% of all inquiries to the joint poison information center in Erfurt, Germany (Gemeinsames Giftinformationszentrum Erfurt, GGIZ) that concerned poisoning in children (2.3% in adults). In this patient collective, plant poisoning occupied third place after medical drugs (32%) and chemical substances (24%), and was a more common subject of inquiry than mushroom poisoning (1.5%). METHODS This review is based on pertinent publications retrieved by a selective literature search in PubMed/TOXLINE on plant poisoning and on 12 epidemiologically and toxicologically relevant domestic species of poisonous plants in risk categories 2 and 3 (up to 2021). RESULTS Medical personnel should have basic toxicological knowledge of the following highly poisonous plants: wolfsbane (aconitum), belladonna, angel's trumpet, cowbane (cicuta virosa), autumn crocus, hemlock, jimson weed, henbane, castor bean (ricinus), false hellebore, foxglove (digitalis), and European yew. The intoxication is evaluated on the basis of a structured history (the "w" questions) and the clinical manifestations (e.g., toxidromes). Special analysis is generally not readily available and often expensive and time-consuming. In case of poisoning, a poison information center should be contacted for plant identification, risk assessment, and treatment recommendations. Specimens of plant components and vomit should be obtained, if possible, for further testing. Measures for the elimination of the poisonous substance may be indicated after a risk-benefit analysis. Specific antidotes are available for only a few types of plant poisoning, e.g., physostigmine for tropane alkaloid poisoning or digitalis antibodies for foxglove poisoning. The treatment is usually symptomatic and only rarely evidence-based. Individualized medical surveillance is recommended after the ingestion of large or unknown quantities of poisonous plant components. CONCLUSION The clinician should be able to recognize dangerous domestic species of poisonous plants, take appropriate initial measures, and avoid overdiagnosis and overtreatment. To improve patient care, systematic epidemiological and clinical studies are needed.

Aust Crit Care 2022; 36:298-306. [PMID: 35490109 DOI: 10.1016/j.aucc.2022.03.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2021] [Revised: 02/11/2022] [Accepted: 03/19/2022] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Whole-bowel irrigation (WBI) is a strategy of gastrointestinal decontamination, recommended by several European and American learned societies, which may be used in the management of the poisoned patients. OBJECTIVES The objectives of this study were to describe the feasibility and tolerability of this technique and to compare the clinical outcome of a group of poisoned patients treated with WBI versus that of an untreated group. METHODS This was a retrospective and observational study of data recorded by the Angers Poison Control Centre (PCC) between 2012 and 2018. All cases for which the PCC advised WBI were included. The association between outcomes (clinical deterioration after WBI advised by a PCC, length of hospitalisation), WBI treatment, and relevant associated risk factors was determined using univariate and multivariate logistic regression. RESULTS A total of 257 patients were included. One hundred forty-one patients were treated with WBI with clearly successful induction of diarrhoea in 47 cases (31%). WBI was not initiated in 89 patients. WBI was initiated but unsuccessful (no diarrhoea) in nine cases. The median age is 46 years (interquartile range: 32-55 years), with a sex ratio (M/F) of 1.3. A total of 27 of 150 patients (18%) who underwent WBI had adverse effects possibly linked to WBI, mainly vomiting (n=23). The patients with clinical deterioration (n=49) were irrigated significantly less often (95% confidence interval: 0.13-0.52; p<0.001). After adjustment for sex, age, time to implementation of WBI, type of substance ingested, and admission to intensive care, patients who were treated with WBI were less likely to deteriorate clinically than patients who were not treated with WBI (p<0.001). CONCLUSION Despite a low rate of completion of this procedure, WBI appeared to provide clinical benefits in patients treated in comparison of an untreated group and is associated with an acceptably low risk of direct complications.

Abstract
OBJECTIVES This review aimed to explore and summarize information from available cases of pediatric acute hydroxychloroquine overdose with confirmed hydroxychloroquine exposure to give the clinicians a helpful perspective for its better recognition and management. METHODS Electronic searches were conducted in PubMed/MEDLINE, Web of Science, Scopus, EBSCO and Serbian Citation Index. The abstracts from 2 toxicology conferences were manually checked for additional relevant publications, as well as reference lists of the retrieved publications. Descriptive statistics, narrative summation, and tabulation of the extracted data were made. RESULTS Nine publications and a total of 9 patients were included in the review. Reported age of the patients varied from 2.5 to 16 years (median, 16 years). There were more female patients (77.8%). Estimated total ingested hydroxychloroquine dose was reported in 7 cases (77.8%), and it ranged from 4.0 to 20.0 g (median: 12.0 g). Four patients (44.4%) ingested hydroxychloroquine with a coingestant. Altered mental status (100.0%), cardiotoxicity (88.9%), hypotension (77.8%), and hypokalemia (55.6%) were the most commonly reported clinical manifestations. The majority of the patients were hospitalized (88.9%). More than half of the patients (55.6%) were reported to be treated in the intensive care unit. Most frequently reported therapeutic measures were the following: administration of intravenous fluids/infusions (77.8%), vasopressors (77.8%), bicarbonate therapy-sodium bicarbonate (66.7%), potassium replacement (55.6%), and intubation/ventilation (55.6%). Three patients (33.3%) died. CONCLUSIONS Management of acute hydroxychloroquine overdose in children should be symptomatic and tailored to observed clinical manifestations. There is a need for additional investigations to better understand the impact and effectiveness of various treatment options.

Abstract
INTRODUCTION Data regarding immediate-release (IR)-tramadol exposures in children remain sparse. We aimed to investigate the incidence of IR-tramadol exposures in ≤6-year-old children, to describe the characteristics and resulting outcome of ingestions involving IR-tramadol alone, and to estimate a clinically relevant toxic dose in this population. METHODS Retrospective analysis of IR-tramadol exposures in ≤6-year-old children, collected by the French Poison Control Centers (PCCs) in 2003-2019. The incidence was estimated using IR-tramadol prescription data from the Health Improvement Network database (the French version of THIN). The Poison severity score (PSS) was used to grade severity. RESULTS We found 1260 IR-tramadol exposures in ≤6-year-old children. The number of cases per 100,000 IR-tramadol-treated patients increased over time (p < .0001). One hundred forty-five cases involving IR-tramadol alone were analyzed. The median age was 3.0 years (IQR: 1.9, 4.0), the M/F ratio was 1.5 and the median dose was 5.0 mg/kg (IQR 3.3-11.1). Half of the children (49.7%) remained asymptomatic (PSS0) while 29.6% and 14.5% developed minor (PSS1) or moderate-to-severe (PSS2-PSS3) neurological symptoms, respectively. Twelve children developed respiratory depression. No seizures and no fatality were reported. All symptomatic children recovered within 24 h. The ingested IR-tramadol dose was positively correlated with the PSS (p < .0001). Using a receiver operating characteristic (ROC) curve approach (area under the curve, 0.92; p < .001), ingestion of ≥7.4 mg/kg IR-tramadol was appropriate to recommend hospital referral (sensitivity, 100% [95% confidence interval (CI), 85-100]; specificity, 73% [95% CI, 64-80]; predictive positive value, 39% [95% CI, 35-57]; negative predictive value, 100% [95% CI, 96-100]). Children who ingested <7.4 mg/kg IR-tramadol developed no (n = 68) or minor (n = 22) neurological symptoms. CONCLUSIONS Despite increasing tramadol prescriptions in adults during the study period in France, oral exposure to IR-tramadol in ≤6-year-old children was rare but possibly responsible for severe toxicity. Children with no underlying disease and concomitant medication ingesting <7.4 mg/kg IR-tramadol alone could be observed at home. However, given the observed variability in the onset of seizures after tramadol ingestion, which can occur at ingested tramadol doses below 7.4 mg and even at therapeutic doses, parents or guardians should be specifically warned about the risk of seizures.

Abstract
Toxic ingestions are an increasing concern among pediatric patients in the United States.
Less common, but troubling, are those patients with persistent toxicity symptoms despite
stabilization, resuscitative, and decontamination efforts. We report a case of refractory
serotonin toxicity in an adolescent for whom endoscopic removal of medication remnants led
to the resolution of his clinical course. A 14-year-old male patient with anxiety and
depression, treated with escitalopram and clonidine, presented to an outside hospital
(OSH) emergency department (ED) with tonic-clonic seizure activity and altered mental
status. Non-contrast head computed tomography (CT), complete blood count, and basic
metabolic panel were unrevealing. Repeated seizure activity that occurred in the OSH ED
prompted transfer to a tertiary pediatric care facility for ongoing management. Based on
the constellation of symptoms (tachycardia, muscle rigidity, and lower extremity clonus)
and his medication history, there was concern for serotonin toxicity. His clinical course
worsened, despite treatment with midazolam and cyproheptadine, requiring intubation for
respiratory failure. Because of his refractory symptoms and concern for ongoing medication
side effects, on hospital day 4, he underwent an esophagogastroduodenoscopy (EGD), which
revealed 20 partially digested pills firmly adhered to the gastric mucosa. The pill
fragments were removed and whole bowel irrigation was started, and the patient improved
rapidly, allowing for extubation within 24 hours. An EGD is not routinely used for the
management of toxic ingestions. In addition to this case, evidence from prior case reports
supports the judicious use of EGD as a diagnostic and therapeutic decontamination modality
for severe toxicities.

Prevalence of medically unsupervised activated charcoal use a cause for concern in celiac disease? J Am Pharm Assoc (2003) 2021; 62:546-550.

Abstract
BACKGROUND Celiac disease is an autoimmune disorder that causes an intolerance to gluten. Owing to hidden sources, lack of clear labeling, and cross-contamination, it is not uncommon for individuals with celiac disease to inadvertently ingest gluten. A strict gluten-free diet is the only treatment. OBJECTIVES The purpose of this study was to identify the frequency of activated charcoal use in celiac disease as a purported remedy despite the lack of literature on the safety and efficacy of the practice and to elucidate the manner in which using activated charcoal as a treatment for acute gluten ingestion is being communicated. METHODS Using a descriptive study design, a Web-based survey was sent to members of the celiac disease community via social media pages for voluntary participants 18 years and older diagnosed with celiac disease. Participants were stratified into 3 major groups: (1) those who had heard of using activated charcoal as a remedy to counteract gluten ingestion and used it, (2) those who had heard of using activated charcoal but had not used it, and (3) those who had not heard of using activated charcoal. RESULTS In subjects with celiac disease, 424 of 1613 respondents (26%) had heard of using activated charcoal as a potential remedy for gluten ingestion, and 12% had used it. The top source of information regarding any general information including remedies for maladies related to celiac disease was social media networks 72.3% (879/1613). Of those who had used activated charcoal, 122 participants (61.3%) reported subjectively feeling a reduced severity of symptoms. CONCLUSION Pharmacists should be aware of the off-label use of activated charcoal for accidental gluten ingestion in celiac disease. Pharmacists should educate patients with celiac disease that there is not sufficient evidence to support the use of activated charcoal.

Abstract
INTRODUCTION The use of activated charcoal in poisoning remains both a pillar of modern toxicology and a source of debate. Following the publication of the joint position statements on the use of single-dose and multiple-dose activated charcoal by the American Academy of Clinical Toxicology and the European Association of Poison Centres and Clinical Toxicologists, the routine use of activated charcoal declined. Over subsequent years, many new pharmaceuticals became available in modified or alternative-release formulations and additional data on gastric emptying time in poisoning was published, challenging previous assumptions about absorption kinetics. The American Academy of Clinical Toxicology, the European Association of Poison Centres and Clinical Toxicologists and the Asia Pacific Association of Medical Toxicology founded the Clinical Toxicology Recommendations Collaborative to create a framework for evidence-based recommendations for the management of poisoned patients. The activated charcoal workgroup of the Clinical Toxicology Recommendations Collaborative was tasked with reviewing systematically the evidence pertaining to the use of activated charcoal in poisoning in order to update the previous recommendations. OBJECTIVES The main objective was: Does oral activated charcoal given to adults or children prevent toxicity or improve clinical outcome and survival of poisoned patients compared to those who do not receive charcoal? Secondary objectives were to evaluate pharmacokinetic outcomes, the role of cathartics, and adverse events to charcoal administration. This systematic review summarizes the available evidence on the efficacy of activated charcoal. METHODS A medical librarian created a systematic search strategy for Medline (Ovid), subsequently translated for Embase (via Ovid), CINAHL (via EBSCO), BIOSIS Previews (via Ovid), Web of Science, Scopus, and the Cochrane Library/DARE. All databases were searched from inception to December 31, 2019. There were no language limitations. One author screened all citations identified in the search based on predefined inclusion/exclusion criteria. Excluded citations were confirmed by an additional author and remaining articles were obtained in full text and evaluated by at least two authors for inclusion. All authors cross-referenced full-text articles to identify articles missed in the searches. Data from included articles were extracted by the authors on a standardized spreadsheet and two authors used the GRADE methodology to independently assess the quality and risk of bias of each included study. RESULTS From 22,950 titles originally identified, the final data set consisted of 296 human studies, 118 animal studies, and 145 in vitro studies. Also included were 71 human and two animal studies that reported adverse events. The quality was judged to have a Low or Very Low GRADE in 469 (83%) of the studies. Ninety studies were judged to be of Moderate or High GRADE. The higher GRADE studies reported on the following drugs: paracetamol (acetaminophen), phenobarbital, carbamazepine, cardiac glycosides (digoxin and oleander), ethanol, iron, salicylates, theophylline, tricyclic antidepressants, and valproate. Data on newer pharmaceuticals not reviewed in the previous American Academy of Clinical Toxicology/European Association of Poison Centres and Clinical Toxicologists statements such as quetiapine, olanzapine, citalopram, and Factor Xa inhibitors were included. No studies on the optimal dosing for either single-dose or multiple-dose activated charcoal were found. In the reviewed clinical data, the time of administration of the first dose of charcoal was beyond one hour in 97% (n = 1006 individuals), beyond two hours in 36% (n = 491 individuals), and beyond 12 h in 4% (n = 43 individuals) whereas the timing of the first dose in controlled studies was within one hour of ingestion in 48% (n = 2359 individuals) and beyond two hours in 36% (n = 484) of individuals. CONCLUSIONS This systematic review found heterogenous data. The higher GRADE data was focused on a few select poisonings, while studies that addressed patients with unknown and or mixed ingestions were hampered by low rates of clinically meaningful toxicity or death. Despite these limitations, they reported a benefit of activated charcoal beyond one hour in many clinical scenarios.

Abstract
BACKGROUND This study aims to compare the poisoned patients who could not be administered activated charcoal because of its unavailability with the poisoned patients who were administered charcoal in the later period and to reveal the results about its effectiveness. STUDY QUESTION Is the use of activated charcoal effective against poisoning caused by oral medication? STUDY DESIGN This retrospective cohort study with historical control was planned at a tertiary hospital. Patients older than 18 years were admitted to the emergency department because of oral drug poisoning during the study periods. A total of 1159 patients who were not given activated charcoal and 877 patients who were given activated charcoal were included in this study. MEASURES AND OUTCOMES The frequency of clinical findings secondary to the drug taken, the frequency of antidote use, the frequency of intubation, and the hospitalization length were determined as clinical outcome parameters. RESULTS There was no statistically significant difference in the development of central nervous system findings, cardiovascular system findings, frequency of intubation, and blood gas disorders, as well as the length of hospitalization periods according to the activated charcoal application. Hepatobiliary system findings and electrolyte disturbances were found to be less common in patients given activated charcoal. The frequency of tachycardia, speech impairment, coma, and respiratory acidosis was found to be statistically higher in patients who were administered activated charcoal. The hospitalization period of the patients who were given activated charcoal was longer in patients with drug findings; however, there was no difference in the hospitalization periods of the patients who were given an antidote. CONCLUSIONS The use of activated charcoal in poisoned patients may not provide sufficient clinical benefits. However, clinical studies with strong evidence levels are needed to determine activated charcoal's clinical efficacy, which is still used as a universal antidote.

Abstract
There are many nonopioid central nervous system depressant substances that share a gamma-aminobutyric acid (GABA) receptor-related mechanism of action. These sedatives-hypnotics can be indicated to treat anxiety, seizures, depression, and insomnia but are also used as substances of abuse and used to facilitate sexual assault. Barbiturates, methaqualone, and glutethimide were among the first type A GABA receptor-mediated sedative-hypnotics. Their clinical use was limited for most indications by serious adverse events and strong abuse potential but continue to be used illicitly around the world. The benzodiazepines supplanted barbiturates for most indications because they were less likely to cause severe adverse events in monotherapy. Flunitrazepam is a newer benzodiazepine that is preferentially used recreationally and to facilitate sexual assault. Flunitrazepam has greater potency and higher affinity for the type A GABA receptor than most benzodiazepines. Gamma-hydroxybutyric acid is sought illicitly for its hypnotic, euphoric and anabolic effects as well as to facilitate sexual assault. When any of these GABAergic drugs are used in high doses or with other sedative hypnotic agents, respiratory depression, coma, and death have occurred. Chronic use of these GABAergic drugs can lead to significant withdrawal syndromes. Phenibut and selank are poorly studied Russian drugs with GABAergic mechanisms that are inexplicably sold to US consumers as dietary supplements. Poison control center calls regarding phenibut have increased substantially over the past 5 years. Desired euphoriant effects account for the recreational and illicit use of many GABA-modulating agents. However, illicit use can lead to significant toxicities related to abuse, dependence, and subsequent withdrawal syndromes. Significant evaluation of developing agents with GABA properties should be conducted to determine abuse potential before public access ensues.

Abstract
Equine toxicologic emergencies are relatively uncommon but can cause significant morbidity and mortality in a group of comanaged horses. The field veterinarian's role is to triage the situation, as well as the individual animal. Individual patient stabilization should focus on support of essential organ functions, providing time for treatments to have an effect or for elimination of the toxicant. Decontamination procedures can follow patient stabilization, if appropriate. Antidotes are often not available or feasible for equine intoxications. The field veterinarian should emphasize triage and stabilization before referral and on-site identification and collection of diagnostic samples to support the diagnosis.

Abstract
Introduction Acute pediatric poisoning is an emerging health and social problem. The aim of this study is to describe the characteristics of a large pediatric cohort exposed to xenobiotics, through the analysis of a Pediatric Poison Control Center (PPCc) registry. Methods This study, conducted in the Pediatric Hospital Bambino Gesù of Rome, a reference National Pediatric Hospital, collected data of children whose parents or caregivers contacted the PPCc by phone (group “P”), or who presented to the Emergency Department (group “ED”), during the three-year period 2014–2016. Data were prospectively and systematically collected in a pre-set electronic registry. Comparisons among age groups were performed and multivariable logistic regression models used to investigate associations with outcomes (hospital referral for “P”, and hospital admission for “ED”group). Results We collected data of 1611 children on group P and 1075 on group ED. Both groups were exposed to both pharmaceutical and non-pharmaceutical agents. Pharmaceutical agent exposure increased with age and the most common route of exposure was oral. Only 10% among P group were symptomatic children, with gastrointestinal symptoms. Among the ED patients, 30% were symptomatic children mostly with gastrointestinal (55.4%) and neurologic symptoms (23.8%). Intentional exposure (abuse substance and suicide attempt), which involved 7.7% of patients, was associated with older age and Hospital admission. Conclusions Our study describes the characteristics of xenobiotics exposures in different paediatric age groups, highlighting the impact of both pharmacological and intentional exposure. Furthermore, our study shows the utility of a specific PPCc, either through Phone support or by direct access to ED. PPCc phone counselling could avoid unnecessary access to the ED, a relevant achievement, particularly in the time of a pandemic.

Abstract
Acute poisoning is a widespread emergency that mandates early management decisions for optimal outcomes. An individualized approach is an ideal way to provide those outcomes. Promoting awareness among healthcare professionals managing acute poisoning about the importance of incorporating the pharmacokinetics and following certain criteria to consider interventions such as activated charcoal, antidote, or specific investigations may improve their risk assessment strategies and management plans. To address the main aspects that should be considered to develop a customized poisoning management plan, we conducted this review based on relevant publications recovered by a careful search in PubMed. Our opinions as experts from the King Saud University (KSU) Drug and Poison Information Center (DPIC) were considered in the review.

Abstract
PURPOSE Critical access hospitals (CAH) are an important source of exposures for poison control centers (PCC), yet there is a paucity of literature on how these calls differ from larger, more urban hospitals (UH). This study aimed to compare call characteristics from CAH and UH received by a regional PCC. METHODS This retrospective chart review used the Toxicall® database of the Kansas PCC. All cases involving calls from a health care facility from 1 January 2012 to 31 December 2017 were identified. Cases were then identified as either from a CAH or from one of the four largest UH in Kansas for comparison. CAH were defined using the criteria from the Centers for Medicare & Medicaid Services. All information was de-identified in REDCAPS and analyzed in Microsoft Excel. FINDINGS A total of 12,469 unique patient cases were identified, including 6392 CAH and 6077 UH cases. Patients at UH were more likely to have longer duration of medical effects and experience more severe medical effects. Significant differences in the unique exposures, rates of intentional overdose, routes, and number of exposures were found. Patients at CAH were more likely to receive activated charcoal, flumazenil, and be transferred to another healthcare facility, but were less likely to have been referred by the PCC, need an ICU admission, or require consultation with a toxicologist. CONCLUSIONS PCC calls from CAHs were common and resulted in significant differences when compared to UH calls. Future research is warranted to optimize PCC services for rural hospitals.

Influence of Internal Structure of the Sorbents on Diazepam Sorption from Simulated Intestinal Fluid. APPLIED SCIENCES-BASEL 2021.

Abstract
The capacity of natural Na-montmorillonite and activated charcoal for sorption of diazepam from simulated intestinal fluid (SIF) was studied. The main characteristics of the sorbents were determined. In order to characterize the sorption process of diazepam the influence of the pH, contact time and ethanol presence in SIF was analyzed. Adsorption isotherms for the diazepam-activated charcoal and diazepam-natural Na-montmorillonite systems were determined. The Langmuir isotherm model provided a very good description of diazepam sorption. Furthermore, the pH-drift method was used to determine the specific pH at zero point of charge (pHzpc) of the sorbents. The obtained results show that the internal structure of the sorbents and pH of the SIF solutions are very important for diazepam sorption. Both the surface of the activated charcoal and natural Na-montmorillonite are positively charged below the pHzpc so the sorption of diazepam is higher below this point and occur by van der Waals forces. The presence of ethanol in simulated intestinal fluid lowers the adsorption of diazepam on both sorbents.

Abstract
DAV132 is a novel colon-targeted adsorbent that prevents the deleterious impact of antibiotics on gut microbiota without modifying their systemic availability. A randomized, Latin-square crossover, open-label trial with 2 substudies in 18 and 24 healthy volunteers evaluated the pharmacokinetic (PK) bioequivalence of warfarin, a drug with a narrow therapeutic index (NTI), and clonazepam, both widely used for the treatment of chronic conditions, with or without coadministration of DAV132 7.5 g. PK parameters observed with single doses of 5 mg warfarin and 1 mg clonazepam when administered alone did not differ with the PK parameters when administered concomitantly with or 1 hour before DAV132. Geometric mean ratios (GMRs) for S-warfarin, R-warfarin, and clonazepam Cmax were 102.0, 102.8, and 91.9, respectively, after concomitant administration and 106.5, 107.5, and 95.0, respectively, when administered 1 hour before DAV132. After concomitant administration, GMRs for S-warfarin, R-warfarin, and clonazepam AUClast were 100.5, 100.2, and 94.9, respectively, and 101.9, 101.8, and 101.3, respectively, when administered 1 hour before DAV132. All GMR 90% confidence intervals fell within the prespecified 80% to 125% limit for bioequivalence, indicating a lack of drug-drug interaction. In conclusion, DAV132 did not affect the systemic exposure of 2 NTI drugs absorbed in the proximal intestine.

Abstract
Activated charcoal both reduces primary drug absorption and enhances drug elimination. However, the two mechanisms of action overlap and are indistinguishable from each other. In order to estimate the extend of enhanced elimination, we summarized the effect of activated charcoal on intravenously administered drugs, where reduced drug exposure can be attributed to enhanced elimination. We performed a meta-analysis of randomized controlled studies evaluating the effect of orally administered activated charcoal on the systemic exposure of intravenously administered drugs. We searched the bibliographic databases PubMed, Embase and Cochrane. Meta-regression analyses of selected physiochemical drug properties on the effect sizes of activated charcoal were performed. All but one of 21 included studies used multiple-dose activated charcoal (MDAC). MDAC reduced the median half-life of the intravenously administered study drugs by 45.7% (interquartile range: 15.3%-51.3%) and area under the concentration time curve by 47.0% (interquartile range: 36.4%-50.2%). MDAC significantly improved drug elimination across nine different intravenously administered drugs, but we were unable to identify factors allowing extrapolation to other drugs. The results offer a possible and plausible rationale for the previously observed effects of single-dose activated charcoal beyond the timeframe where ingested drug is present in the gastro-intestinal tract.

Abstract
BACKGROUND Poisoning is one of the leading causes of admission to the emergency department and intensive care unit. A large number of epidemiological changes have occurred over the last years such as the exponential growth of new synthetic psychoactive substances. Major progress has also been made in analytical screening and assays, enabling the clinicians to rapidly obtain a definite diagnosis. METHODS A committee composed of 30 experts from five scientific societies, the Société de Réanimation de Langue Française (SRLF), the Société Française de Médecine d'Urgence (SFMU), the Société de Toxicologie Clinique (STC), the Société Française de Toxicologie Analytique (SFTA) and the Groupe Francophone de Réanimation et d'Urgences Pédiatriques (GFRUP) evaluated eight fields: (1) severity assessment and initial triage; (2) diagnostic approach and role of toxicological analyses; (3) supportive care; (4) decontamination; (5) elimination enhancement; (6) place of antidotes; (7) specificities related to recreational drug poisoning; and (8) characteristics of cardiotoxicant poisoning. Population, Intervention, Comparison, and Outcome (PICO) questions were reviewed and updated as needed, and evidence profiles were generated. Analysis of the literature and formulation of recommendations were then conducted according to the GRADE® methodology. RESULTS The SRLF-SFMU guideline panel provided 41 statements concerning the management of pharmaceutical and recreational drug poisoning. Ethanol and chemical poisoning were excluded from the scope of these recommendations. After two rounds of discussion and various amendments, a strong consensus was reached for all recommendations. Six of these recommendations had a high level of evidence (GRADE 1±) and six had a low level of evidence (GRADE 2±). Twenty-nine recommendations were in the form of expert opinion recommendations due to the low evidences in the literature. CONCLUSIONS The experts reached a substantial consensus for several strong recommendations for optimal management of pharmaceutical and recreational drug poisoning, mainly regarding the conditions and effectiveness of naloxone and N-acetylcystein as antidotes to treat opioid and acetaminophen poisoning, respectively.

Abstract
OBJECTIVE To show the preparation process by the Poisoning Working Group of the Spanish Society of Paediatric Emergencies (GTI-SEUP), of the list of things «not to do» for a paediatric patient who has been exposed to a potentially toxic substance. METHOD The preparation process of the list was carried out in three phases. First: «Brainstorming» that was open to all members of the GTI-SEUP. Second: Recommendations were selected by following modified-Delphi methodology. All participants were asked to rate the proposals (from 1 = strongly disagree to 9 = strongly agree). Those with an average score greater than 8 were accepted (provided that at least two-thirds of the participants had given them a score ≥ 7), and a second consultation was made for the recommendations with an average score between 6 and 8. Third: Writing and creating a consensus of the final document was done. RESULT A total of 11 proposals were initially obtained. Thirty-two of the 57 GTI-SEUP participants completed the scoring questionnaire. In the first consultation, seven «not to do» recommendations were accepted, and four obtained a doubtful average score (between 6 and 8). After the second consultation, the list was made up of eight recommendations. Two refer to general management, four to gastrointestinal decontamination techniques, and two to the administration of antidotes. CONCLUSION The list of actions that should not be taken with a child that has been exposed to a possible poison is a consensus tool, within the GTI-SEUP, to promote improvement in the quality of care offered to these patients. This improvement is based on avoiding unnecessary measures, which can sometimes be harmful to the child.

Abstract
OBJECTIVE To describe a serious adverse event of gastrointestinal obstruction requiring surgery following routine administration of multiple doses of activated charcoal (AC) granules, which were prescribed for carprofen toxicosis. CASE SUMMARY A 2-year-old female neutered Airedale Terrier presented for ingestion of 207 mg/kg of carprofen. Decontamination was initiated with apomorphine to induce emesis. Along with additional supportive care, the dog received an initial dose of 75 mL of AC suspension containing sorbitol by mouth (15.6 g of AC, or 0.6 g/kg), followed by 50 g of AC granules every 8 hours for 4 additional doses. While hospitalized, the dog experienced clinical signs, including vomiting and black diarrhea, as well as bloodwork changes including mild to moderate elevations in kidney and liver enzymes. Given clinical improvement after 72 hours of hospitalization, the patient was discharged for monitoring and ongoing care at home. Two days later, the patient presented again for nausea, dark diarrhea with frank blood, and panting. Abdominal ultrasound showed findings suspicious for partially obstructive foreign material or atypical impacted fecal material partially occluding the distal ileum. Despite medical management overnight, recheck ultrasound the following day demonstrated persistent obstruction with ileal foreign material. Exploratory laparotomy and enterotomy revealed moderate distension and obstruction of the distal ileum with black granular foreign material consistent with charcoal granules. The patient remained in hospital for supportive care for 4 days following the procedure, and all clinical signs were resolved at the time of discharge. NEW OR UNIQUE INFORMATION PROVIDED This report documents a serious adverse event of gastrointestinal obstruction associated with routine multidose AC administration, which has been occasionally reported in people but not in dogs. The potential for this complication should be taken into account when prescribing multiple doses of AC granules.

[PMID: 31219028 DOI: 10.3238/arztebl.2019.0311] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/18/2018] [Revised: 12/18/2018] [Accepted: 03/26/2019] [Indexed: 11/27/2022]
Abstract
BACKGROUND In 2016, according to the German Federal Statistical Office, 178 425 cases of intoxication (poisoning) were treated in German hospitals. The poison control centers in the German-speaking countries gave advice in a total of 268 787 instances of poisoning in that year, and use of activated charcoal was recommended in 4.37% of cases. The application of activated charcoal plays a major role in both primary and secondary detoxification. This article serves as an overview of the mechanism of action, indications, contraindications, modes of application, and dosing of activated charcoal. METHODS This review is based on pertinent publications retrieved by a selective search in PubMed. The opinions of experts from the poison control centers in the German-speaking countries were considered in the interpretation of the data. RESULTS The administration of activated charcoal is indicated to treat moderately severe to life-threatening intoxication. It should be carried out as soon as possible, within the first hour of the ingestion; timed-release preparations can be given up to 6 hours after the ingestion. An important contraindication is impaired consciousness with the danger of aspiration in a patient whose air- way has not yet been secured. Activated charcoal is ineffective or inadequately effective in cases of poisoning with acids or bases, alcohols, organic solvents, inorganic salts, or metals. The proper dosage consists of an amount that is 10 to 40 times as much as that of the intoxicating substance, or else 0.5-1 g/kg body weight in children or 50 g in adults. Repeated application is indicated for intoxications with agents that persist for a longer time in the stomach and for intoxications with timed-release drugs or drugs with a marked enterohepatic or entero-enteric circulation. The routine combination of activated charcoal with a laxative is not recommended. CONCLUSION Even though intoxications are common, there is still no internationally valid guideline concerning the administration of activated charcoal. A precise analysis of the risks and benefits is needed for each administration, and a poison control center should be consulted for this purpose.

Abstract
Metal-organic frameworks (MOFs) have found uses in adsorption, catalysis, gas storage and other industrial applications. Metal Biomolecule Frameworks (bioMOFs) represent an overlap between inorganic, material and medicinal sciences, utilising the porous frameworks for biologically relevant purposes. This review details advances in bioMOFs, looking at the synthesis, properties and applications of both bioinspired materials and MOFs used for bioapplications, such as drug delivery, imaging and catalysis, with a focus on examples from the last five years.

Abstract
Management of the poisoned patient begins with supportive care, assessment of organ function and dysfunction, and consideration of known or suspected poisons. The possibility of multiple ingestions should be considered with intentional exposures or suicide attempts. Enteric decontamination involves treatment to prevent the absorption of toxins from the gastrointestinal system and includes the use of activated charcoal. Poisoned patients may benefit from the use if antidotes are available, or enhanced elimination as with salicylate ion trapping during urinary alkalinization. The use of intravenous lipid therapy is of clinical benefit in poisoning from bupivacaine, amitriptyline, and bupropion. Hemodialysis is the most inexpensive, widely available, and most commonly used method of extracorporeal drug removal in the treatment of poisoning. Chelators with different chemical properties can bind toxic metals, providing an essential mechanism for detoxification, and may be used in combination with extracorporeal therapies such as DFO with HD for aluminum or iron, and DMSA or DMPS with HD to treat arsenic or mercury intoxication. The use of displacers with hemodialysis can be considered to augment clearance of protein-bound toxins.

Abstract
Acute drug poisoning due to accidental or self-damaging overdoses is responsible for 5-10% of emergency medical interventions in Germany. The treatment of asymptomatic to life-threatening courses requires extensive expertise. On the basis of a selective literature search, this article gives an overview of selected clinically relevant, acute drug poisonings with regard to epidemiology, symptomatology, diagnostics, and therapy.Intoxications with psychotropic drugs are the most common drug intoxications. Poisoning with tricyclic antidepressants causes anticholinergic, central nervous, and cardiovascular symptoms. Less toxic are selective serotonin reuptake inhibitors (SSRIs); the intoxication may be characterized by serotonin syndrome. Malignant neuroleptic syndrome is a severe complication of neuroleptic poisoning.Poisoning with analgesics is clinically relevant due to its high availability. For paracetamol poisoning, intravenous acetylcysteine is available as an antidote. Hemodialysis may be indicated for severe salicylate intoxication. Poisoning with nonsteroidal anti-inflammatory drugs is usually only associated with mild signs of intoxication.Poisoning with cardiac drugs (β-blockers and calcium antagonists) can cause life-threatening cardiovascular events. In addition to symptomatic therapy, insulin glucose therapy also plays an important role.The majority of acute drug poisonings can be treated adequately by symptomatic and partly intensive care therapy - if necessary with the application of primary and secondary toxin elimination. Depending on the severity of the intoxication, pharmacology-specific therapy must be initiated.

Abstract
Calcium channel blockers (CCBs) are commonly prescribed cardiovascular medications used in several disease states including hypertension, coronary artery disease, and atrial fibrillation. Inadvertent exposure or intentional overdose of CCBs may result in hypotension, bradycardia, dysrhythmias, conduction disturbances, and hyperglycemia. In the most severe cases, CCB toxicity can lead to rapid cardiovascular collapse. Given the risk of significant morbidity and mortality associated with CCB toxicity, it is important that health care professionals are able to recognize and treat patients who present with a potentially toxic ingestion. Due to the paucity of literature in managing pediatric patients with severe CCB toxicity, treatment strategies for pediatric patients are mostly limited to case reports and extrapolation from expert consensus recommendations for adults. All pediatric patients with a potentially toxic CCB ingestion should be evaluated in the emergency department. Activated charcoal may be considered for asymptomatic patients presenting within an hour of ingestion. Symptomatic patients should be placed under cardiac monitoring and treatments to stabilize the patient's hemodynamics should not be delayed. Traditional first-line IV therapies include small boluses of fluids, calcium, and vasopressors. High-dose insulin has been proposed to independently increase inotropy and improve CCB-induced hypoinsulinemia and insulin resistance that results from CCB inhibition of insulin release from pancreatic β-islet cells. High-dose insulin is recommended as first-line therapy for adults and shows promising efficacy and safety in several pediatric case reports. Intravenous lipid emulsion may be considered in patients who are refractory to first-line therapies, although the data for pediatric patients are extremely limited.

Abstract
OBJECTIVE To assess the administration of a commercially available activated charcoal suspension with sorbitol (ACS) on serum sodium concentrations and hydration status in healthy dogs. DESIGN Prospective study. SETTING Private referral hospital. ANIMALS Nine healthy adult dogs. INTERVENTIONS Dogs were administered 1 mg/kg maropitant (Cerenia; Pfizer Animal Health, New York, NY) intravenously 1 hour prior to charcoal administration. Dogs were administered a single dose of 2 g/kg ACS. MEASUREMENTS AND MAIN RESULTS Blood samples and body weights were obtained prior to charcoal administration and 2, 4, 6, 8, 10, and 12 hours post ACS administration. Venous sodium, potassium, chloride, blood urea nitrogen, creatinine, lactate, packed cell volume, and total plasma protein were measured at each time interval. All dogs returned 2-4 weeks after ACS administration for a 12 hour period of water restriction and to serve as their own control group. The same measurements were repeated during water restriction period as following ACS administration. The increase in serum sodium concentration was significantly higher following ACS administration when compared to control period (P = 0.0002). All dogs administered ACS experienced a significant degree of weight loss (P = 0.0371) when compared to the control period. Following administration of ACS, the hematocrit of the dogs administered ACS was found to be significantly increased (P = 0.0001), when compared to the control period. CONCLUSION Patients that are administered a single dose of ACS are at risk of developing dehydration and secondary hypernatremia as observed in the dogs during the study period. Patients receiving ACS should have electrolytes monitored and would benefit from fluid therapy as previously recommended.

Abstract
Current drug-delivery systems are designed primarily for parenteral applications and are either lipid or polymer drug conjugates. In our quest to inhibit herpes simplex virus infection via the compounds found in commonly used cosmetic products, we found that activated carbon particles inhibit infection and, in addition, substantially improve topical delivery and, hence, the efficacy of a common antiviral drug, acyclovir (ACV). Our in vitro studies demonstrate that highly porous carbon structures trapped virions, blocked infection and substantially improved efficacy when ACV was loaded onto them. Also, using murine models of corneal and genital herpes infections, we show that the topical use of drug-encapsulated carbon (DECON) reduced dosing frequency, shortened treatment duration, and exhibited higher therapeutic efficacy than currently approved topical or systemic antivirals alone. DECON is a nontoxic, cost-effective and nonimmunogenic alternative to current topical drug-delivery systems that is uniquely triggered for drug release by virus trapping.
