| Description |
Intraperitoneal injection of metalaxyl (250 mg/kg) produced a decrease in heart rate lasting for more than 60 min in anesthetized rats. Pretreatment of rats with phentolamine (a nonselective alpha-adrenoreceptor antagonist, ip at 20 mg/kg) and prazosin (an alpha 1-adrenoreceptor antagonist, ip at 5 mg/kg) significantly reduced the bradycardia induced by metalaxyl. Yohimbine (an alpha 2-adrenoreceptor antagonist, ip at 10 mg/kg) did not change the effect of metalaxyl on heart rate. The results suggest that alpha 2-adrenoreceptors mediate the bradycardic effect of metalaxyl.
