Pharmacology
Propranolol Hydrochloride belongs to a group of medicines called beta-adrenergic receptor blockers, and it is commonly used to treat high blood pressure and angina pectoris (chest pain caused by reduced blood flow to the heart). It works by blocking the action of catecholamines at beta-adrenergic receptors, which keeps the heart from beating too fast or too forcefully and reduces the heart's oxygen demand.
When taken by mouth, propranolol is nearly completely absorbed from the gut, though part of the dose is broken down by the liver before it reaches general circulation, as it passes through the portal blood supply. Blood levels peak within 1 to 1.5 hours of an oral dose, and the drug stays in the body with a half-life of roughly 3 to 6 hours. Its breakdown products are then cleared from the body in the urine.
Pregnancy & Breastfeeding
Propranolol falls under pregnancy category C and should not be used in pregnant women. It passes into human breast milk, so caution is advised when giving it to a nursing mother.
