This page compares them: when each is used, how the mechanisms and indications differ, and whether the question "Viagra Professional vs Amiloride" makes sense to ask at all.
What is the relationship?

Mechanisms compared
Viagra Professional: Sildenafil citrate inhibits PDE5, allowing the cyclic GMP produced during sexual arousal to accumulate in penile tissue, which relaxes the smooth muscle of the penile arteries and increases blood inflow. Amiloride: Amiloride blocks the epithelial sodium channel (ENaC) in the distal convoluted tubule and collecting duct of the kidney, reducing sodium reabsorption and indirectly decreasing potassium and hydrogen ion excretion.

Comparing Viagra Professional with Amiloride makes sense when both are in the same clinical decision: the prescriber has weighed both for different but related conditions. If the question is between two options for the same need, the prescriber decides based on prior response, comorbidities and tolerance.
