| pubmed-article:3818041 | pubmed:abstractText | The effect of verapamil on pressor response to Angiotensin II (A II) was investigated in rats. The responses to A II (10, 20, 40 ng, iv) was reduced after verapamil (50 and 100 micrograms, iv per rat) in a dose dependent manner. Treatment for 5 day with verapamil (18 mg/100 g/day, po) let to some reduction in basal blood pressure but pressor response to A II was not changed. Treatment for 20 days significantly reduced the basal blood pressure and increased the responsiveness to A II. it is concluded that Ca++ plays a major role in the pressor responses to A II and that chronic treatment with verapamil may reduce basal blood pressure. | lld:pubmed |
