ABSTRACT
OBJECTIVE:To explore the characteristics and regularities of cardiac damage induced by metranidazole,and pro-vide reference for clinical safe application. METHODS:In retrospective study,58 cases of cardiac damage caused by metranidazole in Henan ADR Monitoring Center for Drug from Jan. 2010 to Dec. 2015 were analyzed statistically. RESULTS:In 58 cases of cardiac damage induced by metranidazole,25 cases were male,33 were female,the ratio of male to female was 0.76∶1,the patients with ADR/ADE aged 15-64 years (74.14%),most were intravenous administration (79.31%) and happened within 30 min (70.69%), cardiac damage mainly manifested as palpitation,severe cases can cause tachycardia and arrhythmia,the ADR improved or cured af-ter withdrawal or symptomatic treatment. CONCLUSIONS:Clinic should strengthen observation of ADR/ADE caused by metranida-zole,especially the monitoring of cardiac toxicity reactions;pharmaceutical manufacturers should improve the drug instructions to in-sure the safety of clinical medication.
ABSTRACT
BACKGROUND/AIMS: The success of Helicobacter pylori eradication is limited by antibiotic resistances, and the primary resistance to metranidazole seems to be high. In this study, the frequency af metronidazole resistance and the eradication rate in metronidazole-resistant H. pylori strain was evaluated. METHODS: Sixty-eight patients were tested for metronidazole resistance using microdilution broth, the E test and disk diffusion method. Twenty-two patients were treated for 14 days with amoxicilline 2000 mg, metronidazole 750 mg, and tripotassium dicitrate bismuth 1200 mg. RESULTS: Metronida-zole resistance was 46% (31/68). The eradication rates for H. pylori was 91.7% in patients with metronidazole-sensistive strains and 70% in patients with metronidazole-resistant strains. CONCLUSIONS: Metronidazole resistance was high (46%) in Korea, however, triple therapy was an efficient method of eradicating H. pylori in both metronidazole sensitive and resistant strains.
