What is Sildenafil 100 mg?
Sildenafil 100 mg, a phosphodiesterase type 5 (PDE5) inhibitor, increases blood flow to the penis. This effect occurs only when sexual excitement is already underway.Doctors frequently prescribe this medication to treat erectile dysfunction (ED) in adult men, helping them achieve and maintain an erection sufficient for sexual activity.
The medication’s action centers on a particular enzyme within the body. By inhibiting this enzyme, the drug promotes the relaxation of smooth muscle tissue within the blood vessels of the penis.
This relaxation, in turn, eases the influx of blood when sexual arousal is present. It’s important to note that physical stimulation is a prerequisite for the medication’s effectiveness.
