Pharmacology

Selective vs non-selective, ISA, and the post-MI cardioprotection rule.

Pulsatile GnRH builds. Continuous GnRH destroys. That paradox is question one. Then: somatostatin for carcinoid crisis, cabergoline for prolactinoma, DDAVP for central DI, vaptans for SIADH. Every hypothalamic axis mapped to its drug.

Block the pump. Flood the cell. Save the heart. The drug that poisons the Na/K-ATPase on purpose · and somehow that makes the heart squeeze harder.

Metformin, sulfonylureas, GLP-1, SGLT2. Mechanism and the side effect that defines each.

Hypertensive crisis on MAOIs. Mechanism, forbidden foods, phentolamine first-line, and the serotonin-syndrome trap.

Five drug classes, five hit points on the HPG axis. GnRH agonists flood the signal to cause a drought. Antagonists cut straight to castration. Abiraterone kills the adrenal backup. AR blockers take the last stand. Docetaxel ends the cell cycle.
