What is the relationship?

Mechanisms compared
Spironolactone: Spironolactone competitively blocks the aldosterone (mineralocorticoid) receptor in the distal tubule, reducing sodium reabsorption and potassium excretion. Vardenafil: Vardenafil selectively inhibits PDE5, the enzyme that breaks down cyclic guanosine monophosphate in the corpus cavernosum.
