What’s the Difference between Avanafil vs Sildenafil?
Erectile dysfunction (ED) includes medical conditions like problem in achieving a proper penile erection, maintaining the penile erection, reduced interest for sexual acts, or lack of energy for the same, or even problems in having a proper intercourse; which often becomes the primary reason behind many conjugal hostilities, and even mental depression.

What is Avanafil?
Avanafil is a generic pharmaceutical drug that has gained much popularity as an effective medication for erectile dysfunction. This drug has been found to have significant selectivity of phosphodiesterase type 5 and a higher selectivity against phosphodiesterase type 1 and phosphodiesterase type 6. Stendra happens to be one of the most well-known branded drugs, as a form of avanafil.
What is Sildenafil?
Sildenafil is also a popular drug to fight out erectile dysfunction. It acts by inhibiting cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5). It boosts up the blood vessels and greater blood circulation to particular areas of the body. Viagra happens to be one of the most well-known branded drugs, as a form of sildenafil.
Key Differences between Avanafil vs Sildenafil
|Nature of Salt
|phosphodiesterase type 5 inhibitor,
|phosphodiesterase type 5 (PDE5)
|6 to 7 hours
|Mechanism of Action
|Works by inhibiting the effect of PDE5. This inhibition leads to penile erection due to the inflow of blood into the area.
|Sildenafil has no direct relaxant effect on isolated human corpus cavernosum, but increases the effect of nitric oxide by inhibiting phosphodiesterase type 5 (PDE5), which is responsible for the degradation of cGMP in the corpus cavernosum. When sexual stimulation causes the local release of Nitric Oxide, inhibition of PDE5 by sildenafil causes increased levels of cGMP in the corpus cavernosum, resulting in effortless muscle relaxation and inflow of blood to the corpus cavernosum. Sildenafil has no effect in the absence of sexual stimulation.

Which one is better: Avanafil vs Sildenafil?
Both medications have got their respective pros and cons. But so far having a longer duration of penile erection is concerned, avanafil clearly wins the race with a 6 to 7 hours capacity.
But although the duration of erection projected by Avanafil is on a higher edge than that of Sildenafil, it is purely a matter of individual requirement, preference, and most importantly suitability, considering the kind of adverse effects these are capable to inflict on different individuals.
