Pindolol was developed at Sandoz at 1960s. Pindolol is a nonselective beta-adrenergic antagonist (beta-blocker) which possesses intrinsic sympathomimetic activity (partial agonist activity) in therapeutic dosage ranges but does not possess quinidine-like membrane stabilizing activity. The partial beta-adrenergic agonistic activity of pindolol in the heart appears to be completely restricted to the sinoatrial pacemaker. In standard pharmacologic tests in man and animals, Pindolol attenuates increases in heart rate, systolic blood pressure, and cardiac output resulting from exercise and isoproterenol administration, thus confirming its beta-blocking properties. In addition to beta-adrenergic activity pindolol demonstrates mixed agonist-antagonist activity at central 5-HT receptors. Although in accordance with the hypothesis that pindolol increases the antidepressant effects of selective serotonin reuptake inhibitors by antagonism of 5-HT at inhibitory 5-HT1A autoreceptors, pindolol possesses partial agonist activity at 5-HT1A receptors. Pindolol tablets are indicated in the management of hypertension.

Conditions:

Bopindolol (4-[benzoyloxy-3-tertbutylaminopropoxy]-2-methylindole hydrogen malonate) is an indole beta-adrenoceptor antagonist bearing a benzoyl ester residue on the beta-carbon atom of the propanolamine side chain. Bopindolol is metabolized by esterase to benzoic acid and an active metabolite, 18-502 [4-(3-t-butylamino-2-hydroxypropoxy)-2-methyl indole], which is further metabolized to 20-785 [4-(3-t-butylaminopropoxy)-2-carboxyl indole]. Bopindolol produces sustained blockade of beta 1- and beta 2-adrenoceptors, has intrinsic sympathomimetic as well as membrane stabilizing actions, inhibits renin secretion, and interacts with 5-HT receptors. Bopindolol is used in the treatment of hypertension. In limited trials bopindolol has also successfully reduced symptoms in patients with angina pectoris, anxiety and essential tremor.
