Pharmacology: | Propranolol, the prototype of the beta-adrenergic receptor antagonists, is a competitive, nonselective beta-blocker similar to nadolol without intrinsic sympathomimetic activity. Propanolol is a racemic compound; the l-isomer is responsible for adrenergic blocking activity. |
Mechanism of Action: | Propranolol competes with sympathomimetic neurotransmitters such as catecholamines for binding at beta(1)-adrenergic receptors in the heart, inhibiting sympathetic stimulation. This results in a reduction in resting heart rate, cardiac output, systolic and diastolic blood pressure, and reflex orthostatic hypotension. |
Absorption: | Propranolol is almost completely absorbed from the GI tract; however, plasma concentrations attained are quite variable among individuals. |
Protein binding: | More than 90% |
Biotransformation: | Hepatic |
Route of elimination: | Propranolol is extensively metabolized with most metabolites appearing in the urine. |
Half Life: | 4 hours |
Toxicity: | Symptoms of overdose include bradycardia, cardiac failure, hypotension, and brochospasm. LD50=565 mg/kg (orally in mice). |
Affected organisms: | Humans and other mammals |
