Abstract
INTRODUCTION Ibuprofen is commonly used as an over-the-counter (OTC) antipyretic and analgesic. As the frequency of its use has increased, there has been a corresponding increase in reports of associated adverse events (AEs). However, these events have not been systematically reported in the literature. Meanwhile, the importance of effective pharmacovigilance in evaluating the benefits and risks of drugs is being recognized. METHODS The data was obtained indirectly from FAERS using the OpenVigil 2 database, lexically mapped using software such as MySQL, Microsoft Excel, and the R language, and then subjected to four more rigorous algorithms to detect risk signals associated with ibuprofen AEs. RESULTS By analyzing data from the past 18 years, 878 ibuprofen-related AEs were identified as primary AEs. Notably, unexpected reproductive system and breast diseases, etc., which were unexpected, were observed as important system organ classes (SOCs) associated with ibuprofen. Among the 651 preferred terms (PTs) that simultaneously satisfy the four arithmetic methods, renal tubular acidosis and lip oedema are proposed as new signals for ibuprofen AEs. CONCLUSION This study explores the important and valuable potential AEs and ADRs of ibuprofen at the SOC and PT levels, respectively. To provide a reference on decision-making for ibuprofen to promote rational clinical dosing.

Abstract
OBJECTIVE Ibuprofen is a widely used nonsteroidal anti-inflammatory drug, which has been occasionally associated with hypokalemia and metabolic acidosis. The objective of this report is to analyze the literature on this issue and to address the underlying pathophysiology. DATA SOURCES Excerpta Medica, the National Library of Medicine, and Web of Science were searched from inception to July 16, 2021. STUDY SELECTION AND DATA EXTRACTION Papers reporting individually documented humans on ibuprofen with hypokalemia, acidosis, or both were retained. Data were extracted using a checklist. DATA SYNTHESIS For the final analysis, we evaluated 41 reports describing 50 cases (26 males and 24 females; 36 adults and 14 children) with often profound hypokalemia, acidosis, or both after ingestion of ibuprofen. Twenty-six cases were acute and 24 long term. Hypokalemia and acidosis occurred not only after ingestion of very high doses but also after ingestion of moderately high or even normal doses of ibuprofen. Laboratory values consistent with an excessive urinary potassium excretion or an altered urinary acidification were often disclosed in most cases. Discontinuation of ibuprofen resulted in a resolution of hypokalemia and acidosis within days in 47 cases. The course was lethal in 3 cases. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE This review highlights potentially fatal side effects of ibuprofen and can help doctors who are confronted with such a situation. CONCLUSIONS These data highlight the potential of ibuprofen to occasionally induce hypokalemia and acidosis of renal origin. Discontinuation of ibuprofen results in a resolution within days.

Abstract
A 17-year-old man was admitted to the paediatric intensive care unit 2 hours following an intentional ingestion of unknown substances. In the first 23 hours of hospitalisation, lactate levels remained elevated at 2-4 mmol/L, during the 24th hour, he developed lactic acidosis with lactate levels increasing from 4 to 16 mmol/L. His neurological status declined, requiring orotracheal intubation. Central and arterial access were obtained, and vasoactive infusions were initiated for haemodynamic support. Due to increasing lactate levels (maximum level >24 mmol/L) and haemodynamic instability, a dialysis line was inserted, and continuous renal replacement therapy (CRRT) was initiated. The lactic acidosis resolved over 10 hours. Serum ibuprofen level subsequently resulted at 841 µg/mL (reference range 10-50). Few reported cases discuss the sequela of large quantity ibuprofen ingestion leading to severe lactic acidosis and multiorgan system failure. Early intervention with CRRT may reverse acidosis, stabilise haemodynamics and halt secondary organ failure.

Abstract
Ibuprofen is a widely used nonsteroidal anti-inflammatory drug, which has recently been associated with increased cardiovascular risk, but its electrophysiological effects have not yet been properly studied in isolated cardiac preparations. We studied the effects of ibuprofen on action potential characteristics and several transmembrane ionic currents using the conventional microelectrode technique and the whole-cell configuration of the patch-clamp technique on cardiac preparations and enzymatically isolated ventricular myocytes. In dog (200 µM; n = 6) and rabbit (100 µM; n = 7) papillary muscles, ibuprofen moderately but significantly prolonged repolarization at 1 Hz stimulation frequency. In dog Purkinje fibers, repolarization was abbreviated and maximal rate of depolarization was depressed in a frequency-dependent manner. Levofloxacin (40 µM) alone did not alter repolarization, but augmented the ibuprofen-evoked repolarization lengthening in rabbit preparations (n = 7). In dog myocytes, ibuprofen (250 µM) did not significantly influence IK1, but decreased the amplitude of Ito and IKr potassium currents by 28.2% (60 mV) and 15.2% (20 mV), respectively. Ibuprofen also depressed INaL and ICa currents by 19.9% and 16.4%, respectively. We conclude that ibuprofen seems to be free from effects on action potential parameters at lower concentrations. However, at higher concentrations it may alter repolarization reserve, contributing to the observed proarrhythmic risk in patients.

Abstract
NSAIDs are nonsteroidal anti-inflammatory drugs, thus, they will provide analgesic, antipyretic, anti-inflammatory, antiplatelet effects. Severe poisoning and death because of acute intoxication can occur by ingestions of more than 400 mg/kg. This cross-sectional retrospective study was carried out in on all patients referred to Loghman Hakim Hospital from 2011 to 2016. Grouping of our patients was based on the amount of NSAID ingestion, Type of NSAID, patient's conscious level according to Reed Scaling criteria, suicide attempt, and gender. Data were analyzed using the SPSS software. A P-value of 0.05 or less was considered to be statistically significant. The period prevalence of NSAID poisoning was 0.14% and the incidence was 3.816/100,000/year. The uppermost number of poisoning were seen in 2012 (20.96%). Mean age was 23.75 ± 9.76 years and most of the intoxications were seen in females (66.37%). Of the patients, 140 (61.13%) had ingested less than 200 mg/kg, and 9.17% committed suicide having a mortality rate of 0.43%. The most common NSAIDs that had been used were Ibuprofen (73.79%). Of patients, 83.4% underwent through common complications of NSAID poisoning. We find significant relationship between the type of NSAID and higher sodium, BUN, ALT, ALP, CPK levels in men, and higher LDH level in women. Besides, we found substantial correlation between using short-acting NSAIDs and female gender, suicide action, arrival to the hospital less than 12 h, amounts under 200 mg/kg, hospitalization longer than 12 h, and presentation of loss of consciousness.

Ibuprofen plasma concentration profile in deliberate ibuprofen overdose with circulatory depression treated with therapeutic plasma exchange: a case report. BMC Pharmacol Toxicol 2017; 18:81.

Abstract
BACKGROUND Inquiries relating to ibuprofen overdose have more than tripled in the last ten years in our poison control center. Although the vast majority of cases have a benign clinical course, there are few severe or even fatal cases present with refractory circulatory failure. CASE PRESENTATION We describe a case of a 48 year-old male with suicidal mono-ingestion of approximately 72 g ibuprofen. Despite an initial rapid spontaneous drop in the total ibuprofen plasma concentration (IPC) from 550 to 275 mcg/mL within the first 5 h after admission, the patient developed a circulatory failure, refractory to aggressive fluid resuscitation and high doses of vasopressors. Due to ibuprofen's favorable pharmacokinetics (>95% bound to albumin, low volume of distribution) and in the absence of specific therapeutic alternatives thereby avoiding escalating vasopressor doses, therapeutic plasma exchange (TPE) for extracorporeal elimination of ibuprofen was considered as a therapeutic rescue option. An improvement of hemodynamics with a significant reduction of vasopressors was observed with TPE-initiation. However, neither the observed IPC-profile nor a pharmacokinetic (PK) simulation provided evidence for a quantitative effective elimination of ibuprofen by TPE. Based on PK-modeling we calculated an overall ibuprofen half-life of 17.2 h for the entire observation period over 5 days. CONCLUSIONS To our knowledge this is the first report of a severe ibuprofen-mono intoxication treated with TPE and providing serial IPCs over a period of five days, indicating an estimated fivefold overall-elimination half-life of 17.2 h. Despite TPE clinically improved persistent hemodynamic instability, this procedure was neither consistent with the observed IPC-profile nor correlated with a meaningful quantitative elimination of ibuprofen.

Abstract
PURPOSE Suicide attempts by adolescents most commonly involve the overdose of medications. To date, there has been little information on the over-the-counter or prescription medicines that adolescents ingest for self-harm. Identification of medications chosen in suicide attempts may help guide anticipatory guidance to parents by primary care providers and Poison Centers in prevention programs. METHODS This was a retrospective observational study using the American Association of Poison Control Center's National Poison Data System. Data were collected on patients aged 13-19 years old at the time of their substance ingestion, between the years 2004 and 2013 and that were coded as reason for ingestion of "intentional-suspected suicide." RESULTS During the 10-year study period, there were 390,560 poison center calls for intentional-suspected suicide in the United States between 2004 and 2013, accounting for 80.3% of all "intentional" ingestion calls in the adolescent population. Over the entire age range, the most common substance ingested included acetaminophen (10.9%), ibuprofen (9%), selective serotonin reuptake inhibitors (7.7%), atypical antipsychotic (6%), and antihistamines (5%). The most common medications coded as resulting in major clinical effects or death were antidepressants and atypical antipsychotics. CONCLUSIONS Adolescent ingestion choices for suicide attempts have remained relatively consistent over the past 10 years. However, there was a recent decrease in selective serotonin reuptake inhibitor ingestions. The most common medications used in an overdose attempt were ibuprofen and acetaminophen. Further preventative efforts are needed in this at-risk population from multiple providers at various levels.

Abstract
Nonsteroidal anti-inflammatory drugs (NSAIDs) are one of the most widely used classes of medications in children. Despite a reported positive safety profile, NSAIDs have been associated with toxicities in both overdose and routine use. Most children with NSAID overdoses are asymptomatic and should be managed conservatively, whereas a small number may present with severe symptoms. We review NSAID exposures in children and strategies for their clinical evaluation and management.

Abstract
CONTEXT Massive naproxen overdose is not commonly reported. Severe metabolic acidosis and seizure have been described, but the use of renal replacement therapy has not been studied in the context of overdose. CASE DETAILS A 28-year-old man ingested 70 g of naproxen along with an unknown amount of alcohol in a suicidal attempt. On examination in the emergency department 90 min later, he was drowsy but had normal vital signs apart from sinus tachycardia. Serum naproxen level 90 min after ingestion was 1,580 mg/L (therapeutic range 25-75 mg/L). He developed metabolic acidosis requiring renal replacement therapy using sustained low efficiency dialysis (SLED) and continuous venovenous hemofiltration (CVVH) and had recurrent seizure activity requiring intubation within 4 h from ingestion. He recovered after 48 h. DISCUSSION Massive naproxen overdose can present with serious toxicity including seizures, altered mental status, and metabolic acidosis. CONCLUSION Hemodialysis and renal replacement therapy may correct the acid base disturbance and provide support in cases of renal impairment in context of naproxen overdose, but further studies are needed to determine the extraction of naproxen.

Abstract
Nurofen Plus is a common analgesic containing ibuprofen and codeine. We present a case of a 38-year-old lady who developed renal tubular acidosis with severe hypokalaemia, after chronic abuse of Nurofen Plus tablets. She presented with confusion and profound biochemical abnormalities requiring critical care admission for electrolyte replacement. Ibuprofen causes renal tubular acidosis due to its effects on carbonic anhydrase activity.

Abstract
A fatality following the ingestion of ibuprofen is reported. Ibuprofen is a prototypical nonsteroidal anti-inflammatory drug widely prescribed as an analgesic, anti-inflammatory, and antipyretic agent. To date, there are few case reports of fatal overdose with ibuprofen, following ibuprofen self-poisoning or accidental overdose. We report the case of a 51-year-old man with medical history of psychiatric disease, who was brought to the emergency department by ambulance with a chief complaint of having taken large amounts of drugs in a suicide attempt.Multiple empty containers of medications (ibuprofen, meloxicam, celecoxib, risperidone, citalopram, ketorolac, bromazepam) were found at the scene. He died 4 hours after admission to the emergency department, despite vigorous supportive care. Toxicological analyses were performed using a gas chromatography/mass spectrometry technique. The estimated ibuprofen concentration in the plasma was 600 μg/mL; gastric content was 200 μg/mL for this compound. Our report describes results of the forensic investigation and discuss the review of the literature.

Abstract
The nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used for their analgesic, anti-inflammatory and antipyretic actions. They are commonly taken in overdose in many areas of the world. The majority of patients with acute NSAID overdose will remain asymptomatic or develop minor self-limiting gastrointestinal symptoms. However, serious clinical sequelae have been reported in patients with acute NSAID overdose and these include convulsions, metabolic acidosis, coma and acute renal failure. There appear to be some differences between the NSAIDs in terms of the relative risk of these complications; in particular mefenamic acid is most commonly associated with convulsions. The management of these serious clinical features is largely supportive and there are no specific antidotes for acute NSAID toxicity.

Overdose of Ferrous Sulphate, Co-Dydramol and Non-Steroidal Anti-Inflammatory Drugs, Leading to Fatal Hepatotoxicity. J Intensive Care Soc 2011.

Abstract
A 27-year-old woman died within 48 hours of an overdose of ferrous sulphate, co-dydramol and non-steroidal anti-inflammatory drugs (NSAIDs) from shock secondary to acute liver failure. Her serum iron level at five hours postingestion was lower than that of many non-fatal, pure ferrous sulphate overdoses in published studies. This case highlights the importance of knowing the signs, symptoms and prognostication of ferrous sulphate toxicity and appreciation of the cumulative fatal effects of polypharmacy overdose.

Abstract
Ibuprofen was the first over-the-counter nonsteroidal anti-inflammatory drug available in the United States. Despite being a common agent of ingestion, significant toxicity in overdose is rare. We report a case of a massive ibuprofen ingestion who developed polyuria, acidosis, and coma but survived, despite having a serum ibuprofen concentration greater than previous fatal cases. A 19-year-old man ingested 90 g (1,200 mg/kg) ibuprofen. He was initially awake and alert, but his level of consciousness deteriorated over several hours. Seven hours following the ingestion, he was intubated and mechanically ventilated secondary to loss of airway reflexes. He developed a lactic acidosis and polyuria, which lasted for nearly 24 h. His serum creatinine peaked at 1.12 mg/dL. An ibuprofen level drawn 7 h postingestion was 739.2 mg/L (therapeutic 5-49 mg/L). We describe a case of a massive ibuprofen overdose characterized by metabolic acidosis, coma, and a state of high urine output who survived with aggressive supportive care. This case is unique in several ways. First, ibuprofen levels this high have only rarely been described. Second, polyuria is very poorly described following ibuprofen ingestions.

Abstract
Metabolic acidosis may occasionally develop in the course of treatment with drugs used in everyday clinical practice, as well as with the exposure to certain chemicals. Drug-induced metabolic acidosis, although usually mild, may well be life-threatening, as in cases of lactic acidosis complicating antiretroviral therapy or treatment with biguanides. Therefore, a detailed medical history, with special attention to the recent use of culprit medications, is essential in patients with acid-base derangements. Effective clinical management can be handled through awareness of the adverse effect of certain pharmaceutical compounds on the acid-base status. In this review, we evaluate relevant literature with regard to metabolic acidosis associated with specific drug treatment, and discuss the clinical setting and underlying pathophysiological mechanisms. These mechanisms involve renal inability to excrete the dietary H+ load (including types I and IV renal tubular acidoses), metabolic acidosis owing to increased H+ load (including lactic acidosis, ketoacidosis, ingestion of various substances, administration of hyperalimentation solutions and massive rhabdomyolysis) and metabolic acidosis due to HCO3- loss (including gastrointestinal loss and type II renal tubular acidosis). Determinations of arterial blood gases, the serum anion gap and, in some circumstances, the serum osmolar gap are helpful in delineating the pathogenesis of the acid-base disorder. In all cases of drug-related metabolic acidosis, discontinuation of the culprit medications and avoidance of readministration is advised.

Management of fever in children: summary of the Italian Pediatric Society guidelines. Clin Ther 2009; 31:1826-43. [PMID: 19808142 DOI: 10.1016/j.clinthera.2009.08.006] [Citation(s) in RCA: 62] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/20/2009] [Indexed: 11/28/2022]
Abstract
OBJECTIVE This article summarizes the Italian Pediatric Society guideline on the management of the signs and symptoms of fever in children, prepared as part of the National Guideline Program (NGLP). METHODS Relevant publications in English and Italian were identified through searches of MEDLINE and the Cochrane Database of Systematic Reviews from their inception through December 31, 2007. Based on the consensus of a multidisciplinary expert panel, the strength of the recommendations was categorized into 5 grades (A-E) according to NGLP methodology. SUMMARY In the health care setting, axillary measurement of body temperature using a digital thermometer is recommended in children aged <4 weeks; for children aged > or =4 weeks, axillary measurement using a digital thermometer or tympanic measurement using an infrared thermometer is recommended. When body temperature is measured at home by parents or care-givers, axillary measurement using a digital thermometer is recommended for all children. Children who are afebrile when seen by the clinician but are reported to have had fever by their caregivers should be considered febrile. In special circumstances, high fever may be a predictive factor for severe bacterial infection. Use of physical methods of reducing fever is discouraged, except in the case of hyperthermia. Use of antipyretics-paracetamol (acetaminophen) or ibuprofen-is recommended only when fever is associated with discomfort. Combined or alternating use of antipyretics is discouraged. The dose of antipyretic should be based on the child's weight rather than age. Whenever possible, oral administration of paracetamol is preferable to rectal administration. Use of ibuprofen is not recommended in febrile children with chickenpox or dehydration. Use of ibuprofen or paracetamol is not contraindicated in febrile children with asthma. There is insufficient evidence to form any recommendations concerning fever in children with other chronic conditions, but caution is advised in cases of severe hepatic/renal failure or severe malnutrition. Newborns with fever should always be hospitalized because of the elevated risk of severe disease; paracetamol may be used, with the dose adjusted to gestational age. Use of paracetamol or ibuprofen is not effective in preventing febrile convulsion or the adverse effects of vaccines.
