Study Notes
Cholinergic Agonists
- Bethanechol: Stimulates muscarinic receptors, used to treat urinary retention and gastrointestinal atony.
- Carbachol: Cholinergic agonist that affects both muscarinic and nicotinic receptors.
Cholinergic Antagonists
- Scopolamine: Blocks muscarinic receptors, used for motion sickness and pre-operative medication.
- Cyclopentolate: Blocks muscarinic receptors, used for eye dilation during ophthalmic examinations.
- Atropine: A muscarinic antagonist that blocks acetylcholine, often used to decrease salivary secretions.
- Rincotide: Used for Parkinson's disease by stimulating nicotinic receptors.
- Rocuronium: Depolarizing neuromuscular blocker, inhibits nicotinic receptors, used for muscle relaxation during surgical procedures.
Indirect Cholinergic Agonist
- Neostigmine: Reversible inhibitor of acetylcholinesterase, used to diagnose and treat myasthenia gravis.
Adrenergic Antagonists
- Esmolol: Short-acting selective beta-1 blocker, used to treat hypertension.
- Carvedilol: Blocks beta-1 and beta-2 receptors, used for hypertension and heart failure.
- Labetalol: Blocks alpha-1, beta-1, and beta-2 receptors, used for hypertension and hypertensive emergencies.
Adrenergic Agonists
- Isoproterenol: Stimulates beta receptors, used to treat heart block and bradycardia.
