  • Some tertiary antimuscarinic amines related to oxotremorine were compared with atropine and scopolamine for their ability to block physostigmine-induced hypertension and acetylcholine-induced hypotension in rats. These cardiovascular responses are mediated via muscarinic receptors in the brainstem and on the vasculature, respectively. In urethane-anesthetized rats, physostigmine (77 nmol/kg i.v.) increased mean arterial pressure 40 +/- 5 mm Hg. One hour later, each rat received a single dose of… CONTINUE READING
