Flashcards

Tamsulosin

Selectively blocks alpha-1 adrenergic receptors, relaxing smooth muscle in the prostate and bladder neck.

Varenicline

A partial agonist of alpha-4 beta-2 nicotinic acetylcholine receptors, aiding in smoking cessation.

Ephedrine

Acts as an agonist at both alpha and beta adrenergic receptors, leading to increased heart rate and blood pressure.

Organophosphates

Irreversibly inhibit acetylcholinesterase, leading to acetylcholine accumulation. Primarily affects muscarinic and nicotinic receptors.
