Sildigra 100 mg shares its mechanism of action with the renowned Viagra, both containing the active ingredient sildenafil citrate. Erectile dysfunction involves a complex process initiated in the brain and culminating in penile rigidity. Upon sexual stimulation, signals prompt increased blood flow to the male reproductive organ. Sildenafil citrate, a PDE5 blocker, is crucial in counteracting the enzyme’s restrictive role on blood vessels, ensuring improved blood provision and sustained erection.
