Avanafil vs Sildenafil: Speed Against Price

PDE5 inhibitors block other phosphodiesterase enzymes to varying degrees, and that cross-reactivity is where the characteristic side effects come from. Sildenafil has some activity at PDE6 in the retina — hence the blue tinge and light sensitivity. Avanafil was designed later, with far greater selectivity for PDE5.

The result is a cleaner side-effect profile: less headache, essentially no visual disturbance, and less muscle ache than tadalafil. If side effects were what made you stop taking sildenafil, this is a real and predictable difference rather than a marketing claim.

For planned sex, the difference between 20 minutes and 50 minutes is largely academic. It becomes meaningful in specific situations:

• Where a long lead time itself creates anticipatory anxiety — watching the clock is its own problem.
• Where sex tends to arise without planning and taking a tablet an hour ahead is not realistic.
• Where you routinely eat a substantial meal beforehand, since avanafil is much less affected by food.
• Where a partner is uncomfortable with the obvious ritual of planning around a tablet.

This is what decides it for most men. Generic sildenafil has had years of price erosion; avanafil has had far less generic competition, and it shows. Depending on where you buy, the difference can be severalfold per dose.
