Cardiac glycosides Flashcard Deck - 10 Cards

Flashcard 1: Cardiac glycosides (e.g. digoxin) exert their effects via inhibition of the _____ pump

Answer: Na+-K+ ATPase

Flashcard 2: Magnesium may be used as an antiarrhythmic to treat _____ toxicity

Answer: digoxin

Flashcard 3: What class of drugs directly inhibit the Na+-K+ ATPase pump?_____

Answer: Cardiac glycosides (e.g. digoxin)

Flashcard 4: One factor that predisposes to digoxin toxicity is _____ insufficiency, which decreases drug excretion

Answer: renal

Flashcard 5: Digoxin is useful in the treatment of _____ fibrillation (and flutter)

Answer: atrial

Flashcard 6: 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 7: sildenafil

Answer: PDE5 inhibitor

Flashcard 8: 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 9: 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 10: Ischemic priapism is treated with corporal aspiration, intracavernosal _____, or surgical decompression to prevent ischemia

Answer: phenylephrine
