Sildenafil and Vardenafil basics
Sildenafil, as mentioned, is the first FDA-approved medication in 1998 for impotence or Erectile Dysfunction.
The active ingredient in Viagra and generic Viagra medications is Sildenafil.
On the other hand, FDA approved Vardenafil in 2003, and it came into the market under the brand name Levitra.
Other generic variants of Vardenafil include Vilitra, Filitra, and Snovitra.
Sildenafil is also used in treating Pulmonary Arterial Hypertension. Whereas, Vardenafil is only used as an Erectile Dysfunction medication.
Vardenafil vs Sildenafil: How do they work
Vardenafil and Sildenafil work in the same way.
They both belong to the group of Phosphodiesterase type 5 (PDE5) inhibitors.
PDE5 inhibition raises the levels of cyclic Guanosine Monophosphate (cGMP).
The raised cGMP levels help relax the smooth muscles. It also dilates the blood vessels in the penile region.
The dilation of blood vessels aids to increase blood circulation in the penile area.
This increased blood circulation will help a man or AMAB to get a strong erection.
However, sexual stimulation is essential to achieve an erection.
