The influence of chronically administered (6 weeks) herbicides (KAR, 2,4-D and 2,4,5-T) on pharmacological effects of quinidine, reserpine and strophantin K in mice and rats was examined in vivo. The investigated herbicides produced in mice an increase in acute toxicity of strophantin K, the acute toxicity of either reserpine oro quinidine being unchanged. The herbicides alone, after 6 weeks administration, significantly increased mean arterial pressure of rats, however the hypotensive response to reserpine was not statistically influenced in these animals as compared with controls. The prolonged administration of investigated herbicides produced also the increased sensibility of heart to the arrhythmic effects of quinidine and ouabain as observed in the ecg pattern in rats treated with increasing doses of these agents. The studies indicate the significance of the possible pharmacological interactions between the drugs affecting cardiovascular system and commonly used herbicides in men.
