Overview

Propranolol is a propanolamine that is propan-2-ol substituted by a propan-2-ylamino group at position 1 and a naphthalen-1-yloxy group at position 3. It has a role as an anxiolytic drug, a beta-adrenergic antagonist, a vasodilator agent, an antihypertensive agent, a xenobiotic, an anti-arrhythmia drug, an environmental contaminant and a human blood serum metabolite. It is a member of naphthalenes, a secondary amine and a propanolamine. It is functionally related to a 1-naphthol.

Toxicology

Hepatotoxicity · 1 item

Mild-to-moderate elevations in serum aminotransferase levels occur in less than 2% of patients on propranolol and are usually transient and asymptomatic, resolving even with continuation of therapy. Despite its widespread use, propranolol has not been convincingly linked to instances of clinically apparent liver injury; the few cases reported have generally occurred in patients who were receiving other well known hepatotoxic agents or were associated with elevations in serum enzymes only without jaundice.

Adverse Effects · 2 items

Skin Sensitizer - An agent that can induce an allergic reaction in the skin.

Common side effects of using propranolol include bradycardia, gastrointestinal issues, abdominal pain, nausea, erectile dysfunction, and wheezing/bronchospasms. Propranolol use can also cause drowsiness, fatigue, and cold extremities. Some extreme side effects to be aware of include allergic reactions, insulin resistance, and hallucinations. Prescribers need to explain and discuss all of the side effects before giving patients a prescription for propranolol.

Toxicity SummaryIngestion of greater than 1 g of propranolol in 24 hours can potentially be lethal and lead to profound bradycardia, bradyarrhythmia, hypotension, bronchospasm.

Protein BindingApproximately 90% of propranolol is protein bound in plasma. Other studies have reported ranges of 85-96%.
Pharmacodynamics · 1 item

Propranolol is a beta-adrenergic receptor antagonist used to treat hypertension. Propranolol has a long duration of action as it is given once or twice daily depending on the indication. When patients abruptly stop taking propranolol, they may experience exacerbations of angina and myocardial infarctions.

Mechanism of Action · 1 item

Propranolol is a nonselective β-adrenergic receptor antagonist. Blocking of these receptors leads to vasoconstriction, inhibition of angiogenic factors like vascular endothelial growth factor (VEGF) and basic growth factor of fibroblasts (bFGF), induction of apoptosis of endothelial cells, as well as down regulation of the renin-angiotensin-aldosterone system.

Biological Half-LifeThe elimination half-life of propranolol is approximately 8 hours. The plasma half-life of propranolol is 3 to 6 hours.
Metabolism/Metabolites · 2 items

Propranolol undergoes side chain oxidation to α-naphthoxylactic acid, ring oxidation to 4’-hydroxypropranolol, or glucuronidation to propranolol glucuronide. It can also be N-desisopropylated to become N-desisopropyl propranolol. 17% of a dose undergoes glucuronidation and 42% undergoes ring oxidation.

Propranolol has known human metabolites that include (2S,3S,4S,5R)-3,4,5-Trihydroxy-6-[1-naphthalen-1-yloxy-3-(propan-2-ylamino)propan-2-yl]oxyoxane-2-carboxylic acid.
