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.
