Sildigra 75 mg contains sildenafil citrate, a medication that works by improving blood flow to the penis to help men with erectile dysfunction (ED) achieve and maintain an erection. It is a PDE 5 inhibitor. PDE 5 enzymes in the erectile tissues hinder the process of erection in men.
Erectile dysfunction often results from insufficient blood flow to the penis. Sildigra 75 mg enhances blood flow by maintaining the biochemical processes necessary for an erection.
Mechanism of Action
Sexual Stimulation Required
The medication only works in the presence of sexual stimulation; it does not act as an aphrodisiac or increase sexual desire. Sildigra requires sexual arousal to be effective. It does not cause an erection on its own.
Release of Nitric Oxide (NO)
During sexual stimulation, our body releases nitric oxide (NO) to augment the blood flow in the erectile tissues (corpus cavernosa) surrounding the penis.
CGMP Production
NO activates an enzyme called Guanylate Cyclase, increasing cyclic guanosine monophosphate (cGMP) levels. CGMP is a signaling molecule that relaxes the smooth muscles in the walls of the penile blood vessels.
Increased Blood Flow
Relaxation of these smooth muscles allows blood vessels to widen (vasodilation), increasing blood flow to the penis. This leads to an erection in response to sexual stimulation.
Inhibition of PDE5
Sildenafil, the active ingredient in Sildigra, inhibits the enzyme phosphodiesterase type 5 (PDE5). PDE5 breaks down cGMP. By blocking this enzyme, sildenafil ensures cGMP levels remain high, prolonging the duration of the erection.
