Azithromycin has been reported to increase the risk of death from cardiovascular causes among patients with high baseline risk. Since the information is still limited to bridge the gap between electrophysiological properties of azithromycin in vitro and cardiac death in patients, we initially assessed its electropharmacological effects in doses of 3 and 30(More)
Electropharmacological effects of oseltamivir were studied in comparison with pilsicainide using halothane-anesthetized dogs (n = 4) and isolated left atrium of guinea pigs (n = 5). Oseltamivir (0.3, 3 and 30 mg/kg, i.v.) or pilsicainide (1 and 3 mg/kg, i.v.) was additionally administered to the dogs. The low dose of oseltamivir provided clinically relevant(More)
