Autonomic/CV Drugs Flashcard Deck - 10 Cards

Flashcard 1: vardenafil

Answer: PDE5 inhibitor

Extra: erectile dysfunctionpatients taking nitrates (lethal hypotension)inhbit phosphodiesterase 5, resulting in increased cGMP and smooth muscle relaxation in corpus cavernosumheadache, flushing, impaired blue-green color vision, hypotension, dyspepsia

Flashcard 2: sildenafil

Answer: PDE5 inhibitor

Flashcard 3: What is the effect of high-dose Aspirin (salicylates) on oxidative phosphorylation?

Answer: Uncouples oxidative phosphorylation (increases permeability of the inner mitochondrial membrane)

Extra: Aspirin (salicylates) in high doses uncouples oxidative phosphorylation, leading to a decreased ATP production and increased heat production (fever). It also contributes to the metabolic acidosis seen in salicylate toxicity.

Flashcard 4: Mechanism of action of Ouabain?

Answer: Inhibits Na+/K+-ATPase by binding to the K+ binding site

Extra: Ouabain is a cardiac glycoside (similar to digoxin) that binds to the extracellular side of the Na+/K+-ATPase pump, competing with Potassium (K+). This leads to increased intracellular Na+, which in turn decreases the activity of the Na+/Ca2+ exchanger, resulting in increased intracellular Ca2+ and positive inotropy.

Flashcard 5: _____ patients are more sensitive to the side effects of nonbenzodiazepine hypnotics (e.g. cognitive impairment, headache, delirium)
