| Common Name | Penbutolol |

| Description | Penbutolol is only found in individuals that have used or taken this drug. It is a medication in the class of beta blockers, used in the treatment of high blood pressure. [Wikipedia ]Penbutolol competes with adrenergic neurotransmitters such as catecholamines for binding at beta(1)-adrenergic receptors in the heart and vascular smooth muscle and beta(2)-receptors in the bronchial and vascular smooth muscle. Beta(1)-receptor blockade results in a decrease in resting and exercise heart rate and cardiac output, a decrease in both systolic and diastolic blood pressure, and, possibly, a reduction in reflex orthostatic hypotension. |
