Beta-adrenergic receptor[1]

Bometolol (10-30 mg/kg, p.o.) lowers the blood pressure dose-dependently in spontaneously hypertensive rats, deoxycorticosterone and salt hypertensive rats and two kindey, one clip hypertensive rats. In subchronic study, Bometolol (10-30 mg/kg, or 100-300 mg/kg, p.o.) dose-dependently decreases heart rate, plasma renin activity, heart and kindey weitht and incidence of vascular lesion, but shows no antihypertensive effects in all the hypertensive rats[1].

Rats[1] In the acute experments, normal female Donryu strain (DON, 14-15 weeks, 250-270 g), and SHR (17-18 weeks, 180-200 g), DOC (7-9 weeks, 180-210 g), and CLIP (7-9 weeks, 180-210 g) hypertensive rats are used. Bometolol hydrochloride is dissolved in H2O and 0.01% Tween 80 solution at a volume of 5 mL/kg body weight for the acute and subchronic studies, respectively. The doses are in terms of the free base. The solution is administratered orally by a gastric tube. In the acute experiment, H2O (5 mL/kg) is giver to the control groups. In the subchronic experment, the drug is administered once a day for 5 weeks, 5 days per week, and Tween 80 solution (5 mL/kg) is given to the control groups[1].
