متن کاملCirculatory and respiratory effects of guanethidin.
Guanethidin has been shown by Maxwell et al. (1959) to be a potent antihypertensive agent in dogs, and by Page and Dustan (1959) and Leishman et al. (1959) to be hypotensive in human patients. It selectively inhibits sympathetic activity, probably by blocking postganglionic adrenergic neurones. The intention of this study is to examine the acute effect of guanethidin in patients with increased ...
