Difference between Sildenafil vs Vardenafil Explained
Erectile dysfunction problems are more prevalent than what gets officially reported, which means still now there are men who are shying away from proper medical diagnosis and not taking the right kind of medication. Thanks to medications like Sildenafil, Vardenafil, and similar ones, erectile dysfunction is completely curable these days.
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 avanafil.
What is Vardenafil?
Vardenafil is a phosphodiesterase (PDE-5) inhibitor, that is used to cure erectile dysfunction by increasing the blood flow towards the penile area by relaxing the muscles in penile blood vessels. However, sexual stimuli is required in order to induce the erection.
Key Differences between Sildenafil vs Vardenafil Explained
| Parameters | Sildenafil | Vardenafil |
| Nature of Salt | phosphodiesterase type 5 inhibitor, | phosphodiesterase type 5 (PDE5) |
| Erection Duration | 4 hours | 8 hours |
| Mechanism of Action | 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. | Being a phosphodiesterase (PDE) inhibitor, it works by increasing blood flow to the penis; on receiving a sexual stimulation. |
