Experimentally induced hypertensive G-minipigs were used for assessing the antihypertensive effects of acebutolol, a cardioselective beta-adrenergic blocking agent. In the acute experiment, six females were used. Acebutolol (3 mg/kg, i.v.) alone or in combination with furosemide (1 mg/kg, i.v.) or hydralazine (1 mg/kg, i.v.) was administered through an implanted catheter. In the chronic experiments, five females received oral acebutolol (100-200 mg/day). The blood pressure, heart rate, plasma renin activity (PRA) and plasma aldosterone concentration (PAC) were used as parameters. In the acute experiment, there were no marked changes in the blood pressure or heart rate during the nondosing period. Acebutolol alone caused a marked decrease in the blood pressure and heart rate. In the two combination tests, combined administration with acebutolol and furosemide had a greater effect on the blood pressure and heart rate than did acebutolol alone. A combined acebutolol and hydralazine regimen caused a slight reduction not only in the blood pressure, but also in the heart rate compared with acebutolol alone. PRA and PAC remained essentially constant, with minor fluctuations, throughout the nondosing period. Following the injection of acebutolol alone, PRA showed an elevation with a significant rise after three hours and PAC showed a tendency to increase. PRA and PAC generally tended to increase in the case of combined administration with furosemide or hydralazine, but these tendencies were less conspicuous than with acebutolol alone. On the other hand, chronic treatment with acebutolol produced a significant decrease in the heart rate from two weeks after the administration and in the blood pressure from four weeks.(ABSTRACT TRUNCATED AT 250 WORDS)
