J Vet Pharmacol Ther 2024; 47:208-214. [PMID: 38032073 DOI: 10.1111/jvp.13421] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Revised: 11/14/2023] [Accepted: 11/19/2023] [Indexed: 12/01/2023]
Abstract
Metronidazole (MTZ) is a 5-nitroimidazole anti-bacterial and anti-protozoal drug. In human and companion animal medicine, MTZ remains widely used due to its effectiveness against anaerobic bacteria and protozoa. In farm animals, however, MTZ is currently prohibited in several countries due to insufficient data on nitroimidazoles. The purpose of this study was to assess its pharmacokinetics (PK) in geese after single intravenous (IV) and oral (PO) administrations. Fifteen-month old healthy male geese (n = 8) were used. Geese were subjected to a two-phase, single-dose (10 mg/kg IV, 50 mg/kg PO), open, longitudinal study design with a two-week washout period between the IV and PO phases. Blood was drawn from the left wing vein to heparinized tubes at 0, 0.085 (for IV only), 0.25, 0.5, 0.75, 1, 1.5, 2, 4, 6, 8, 10, 24, and 48 h. Plasma MTZ concentrations were measured using HPLC coupled to an UV detector, and the data were pharmacokinetically analyzed using PKanalix™ software with a non-compartmental approach. MTZ was still quantifiable and well above the LLOQ at 24 h after both routes of administration. Following IV administration, terminal elimination half-life, volume of distribution, and total clearance were 5.47 h, 767 mL/kg, and 96 mL/h/kg, respectively. For the PO route, the bioavailability was high (85%), and the mean peak plasma concentration was 60.27 μg/mL at 1 h. When parameters were normalized for the dose, there were no statistically significant differences for any of the PK parameters between the two routes of administration. The study shows that oral administration of MTZ seems to be promising in geese, although comprehensive research on its pharmacodynamics and multiple-dose studies are necessary before its adoption in geese can be further considered.

Curr Rev Clin Exp Pharmacol 2024; 19:269-284. [PMID: 37264661 DOI: 10.2174/2772432819666230601155545] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2023] [Revised: 04/02/2023] [Accepted: 04/18/2023] [Indexed: 06/03/2023]
Abstract
BACKGROUND A substantial number of research studies on metronidazole-related cutaneous symptoms have recently been published. Our objective was to identify and evaluate descriptive studies that described metronidazole-related skin manifestations, therapeutic interventions, and consequences. METHODS A comprehensive literature search was carried out in the PubMed, Scopus, and grey literature databases from inception to April 2022 without any constraints, as well as a snowball search in Google and a search in Google Scholar. Descriptive articles describing metronidazole-related cutaneous manifestations were considered for the review. Two distinct reviewers carried out the research selection, data extraction, and quality assessment; any discrepancies were resolved by consensus with the third reviewer. RESULTS About 24 out of 4648 descriptive studies, including 26 patients (20 Female patients and 6 male patients), were included in this review. The included studies comprised a range of ages from 16 to 78 years old. Metronidazole was indicated for the treatment of bacterial vaginosis, trichomoniasis, sepsis, anti-infection therapy, perforated appendicitis, rosacea, vaginal discharge, dysentery, acne rosacea, trichomonal vaginitis, lichen planus, liver abscess, facial rosacea, intestinal amoebiasis, and gingivitis. Fixed drug eruption was the most common skin manifestation which was reported in 7 cases included in this review. Cutaneous manifestations were ameliorated by cessation of the offending drug and by apportioning antihistamines, topical steroids, parenteral corticosteroids, emollients, and topical moisturizers. CONCLUSION Clinicians and healthcare professionals should be cognizant of the potential cutaneous adverse drug reactions (CADRs) induced by metronidazole to mitigate fatal circumstances. The management of the CADRs appears to respond effectively with immediate drug discontinuation and supportive therapy.

Abstract
Acute gastroenteritis (AGE) is the highest cause of mortality worldwide in children under the age of 5 years, with the highest mortalities occurring in low-to-middle income countries. Treatment can involve use of unregulated herbal medication and antibiotics. A cross sectional study was carried out to investigate the use of antibiotics and traditional herbal medications in the management of AGE among Yòrùbá-speaking communities in Kwara State, Nigeria. Our findings suggest habitual use of antibiotics (54.6%) and herbal medication (42.5%) in the management of AGE with high levels of self-prescription of antibiotics (21.7%) and herbal medications (36.2%) within the community. Ethanolic extracts of selected herbal plants reported (i.e. Aristolochia ringens, Azadirachta indica, Chromolaena odorata, Etanda Africana, Ficus capensis, Ficus vogelii, Mangifera indica, Momordica charantia, Ocimum gratisimum, Senna alata, Sorghum bicolor and Vernonia amygdalina) were investigated for antibacterial properties, using bacteria known to be causative agents of AGE. Our findings showed that, with exception of Ficus vogelii, which enhanced bacterial growth, the plant extracts reported all showed some antibacterial activity. We further discuss our findings within a regulatory context, with the aim to guide the use of traditional and herbal medication in low-to medium income countries (LMICs) and reduce the potential risks associated with the development of antimicrobial resistance.

Abstract
INTRODUCTION Metronidazole is commonly prescribed for intra-abdominal infections. Oral metronidazole has high bioavailability (>95%) and intravenous metronidazole should be reserved for patients not suitable for oral preparations. METHODS AND MATERIALS This full cycle audit evaluated the type of metronidazole preparation prescribed in adult emergency surgical patients requiring first-line empirical antimicrobial therapy for intra-abdominal infections. The criterion for audit was the proportion of patients who were prescribed intravenous metronidazole when the oral route was available. The first cycle included all consecutive eligible patients between 20 April and 14 May 2020. After an intervention phase educating prescribers about the similar pharmacokinetic properties of oral and intravenous metronidazole, clinical practice was reaudited between 22 June and 16 July 2020. Data were collected by case note and drug chart review. RESULTS A total of 54 patients were included in the first audit cycle. Of these, 11 (20.4%) were prescribed oral metronidazole and 43 (79.6%) were prescribed intravenous metronidazole. In the majority of cases (35/43, 81.4%), intravenous metronidazole was prescribed in the absence of clear contraindications to the oral preparation. Of the 61 patients included in the reaudit cycle, 23 (37.7%) were prescribed oral metronidazole and 38 (62.3%) were prescribed intravenous metronidazole. The proportion of patients prescribed intravenous metronidazole despite being suitable for oral preparation decreased from 81.4% in the first cycle to 34.2% (13/38) in the reaudit cycle (risk ratio 0.42, 95% CI: 0.26 to 0.67, p<0.0001). Prescribing oral metronidazole when suitable saved up to £10.53/day per patient. CONCLUSION This full cycle audit led to a significant improvement in the use of oral metronidazole in suitable patients, as well as a considerable reduction in healthcare costs.

Abstract
The purpose of this study was to evaluate the ability of clindamycin and metronidazole to synergize with natural antimicrobials against biofilms of bacterial vaginosis (BV)-associated Gardnerella vaginalis. Minimum bactericidal concentrations for biofilm cells (MBCs-B) were determined for each antimicrobial. The MBCs-B of lauramide arginine ethyl ester (LAE), subtilosin, clindamycin and metronidazole were 50, 69.5, 20 and 500 μg mL(-1), respectively. A checkerboard assay and isobologram were used to analyze the type of interactions between these antimicrobials. The combination of metronidazole with natural antimicrobials did not inhibit planktonic lactobacilli. Clindamycin with either LAE or with subtilosin was inhibitory for planktonic but not for biofilm-associated lactobacilli. All tested antimicrobial combinations were inhibitory for BV-associated Mobiluncus curtisii and Peptostreptococcus anaerobius. LAE and subtilosin synergized with clindamycin and metronidazole against biofilms of G. vaginalis but not biofilm-associated vaginal lactobacilli. The biofilms of BV-associated pathogens can be controlled by synergistically acting combinations of conventional antibiotics and natural antimicrobials which will help better management of current antibiotics, especially considering robust bacterial resistance. Our findings create a foundation for a new strategy in the effective control of vaginal infections.

Abstract
BACKGROUND AND AIM Helicobacter pylori (H. pylori) infection is a strong risk factor for the development of gastric cancer. In 2013, the Japanese government approved H. pylori eradication therapy in patients with chronic gastritis as well as peptic ulcer. However, the continuing decline in eradication rates for first-line H. pylori eradication therapies is an urgent problem. In this study, we investigated changes in the first-line eradication rate from 2001 to 2010. METHODS Eradication rates for 7-day triple therapy [proton pump inhibitor (rabeprazole 20 mg, lansoprazole 60 mg, or omeprazole 40 mg)+amoxicillin 1500 mg + clarithromycin (CAM) 400 or 800 mg, daily] were collated from 14 hospitals in the Tokyo metropolitan area. The urea breath test was used for the evaluation of eradication. The cut-off value was less than 2.5%. RESULTS The yearly eradication rates (intention to treat/per protocol) were 78.5/79.5% (2001, n=242), 71.2%/72.9% (2002, n=208), 67.8%/70.5% (2003, n=183), 75.6%/84.6% (2004, n=131), 56.4%/70.5% (2005, n=114), 70.5%/75.8% (2006, n=271), 67.4%/82.0% (2007, n=135), 64.0%/76.3% (2008, n=261), 60.5%/74.3% (2009, n=329), and 66.5%/78.8% (2010, n=370), respectively. Examination of eradication rates according to CAM dosage revealed an eradication rate of 65.6% (383/584) for CAM 400 mg daily, and 68.5% (1124/1642) for CAM 800 mg daily, with no significant difference seen between dosages. CONCLUSION In recent years, eradication rates for first-line triple therapy have obviously decreased, but no noticeable decrease has occurred after 2001.

Abstract
A 74-year-old woman with multiple medical problems including chronic renal failure was admitted for treatment of a diabetic foot infection. On day 12 of therapy with oral ciprofloxacin and metronidazole, the patient experienced generalized myoclonus and muscle twitching. At that time it was realized that although the ciprofloxacin regimen prescribed was a usual dose for a skin and soft-tissue infection, it was excessive for her degree of renal function. This was thought to be the most likely cause of the patient's neurotoxicity. Seizure activity has been reported to occur with the quinolone antibiotics and, with the increasing use of these agents, dose reductions should be kept in mind to avoid potentially serious adverse reactions.

Abstract
To evaluate the possible genotoxic effects of the drug, metronidazole in the fetus, we employed the hamster embryo host-mediated assay. Pregnant golden Syrian hamsters were fed metronidazole at doses ranging from 200 mg/kg to 900 mg/kg on days 11 and 12 of pregnancy. Embryonic cells obtained from the treated animals were studied in vitro for morphologic evidence of transformation. To further assess the significance of the in vitro finding, cells from mass culture were tested for their ability to grow in soft agar. The drug-treated cells and cells previously treated with diethyl nitrosamine (positive controls) showed comparable growth characteristics. To confirm the neoplastic potential of the drug-treated embryonic cells, subcultivated cells from the tenth passage were implanted into nude mice and irradiated immunosuppressed hamsters. Cells from the 300 mg/kg treatment produced fibrosarcoma in nude mice but not in the irradiated hamsters. Cells from no other dose level employed in the study produced tumors in host animals. It is concluded that metronidazole is capable of vertical transmission of potential genotoxic effects to the fetus.

Abstract
High-resolution 1H nuclear magnetic resonance (NMR) spectroscopy at 300 MHz has been used to monitor the metabolism of metronidazole by the perfused rat liver. Samples of perfusate removed at various times during the perfusion show resonances from metronidazole and its major metabolites, as well as those from organic metabolites released from the liver. The major metabolite of metronidazole is shown to be its glucuronide conjugate. Metronidazole metabolism and glucuronide production are both stimulated in livers from rats pretreated with phenobarbitone.
