Fildena 100 mg is a medication commonly prescribed to address erectile dysfunction (ED) in men. It contains sildenafil citrate as its active ingredient, a potent phosphodiesterase type 5 (PDE5) inhibitor. The primary purpose of Fildena 100 mg is to enhance blood flow to the penis, facilitating the achievement and maintenance of erections during sexual stimulation.
Sildenafil citrate in Fildena 100 mg works by inhibiting PDE5, an enzyme that breaks down cyclic guanosine monophosphate (cGMP). Elevated cGMP levels lead to the relaxation of smooth muscle cells in the penile blood vessels, allowing increased blood flow to the penis. This mechanism promotes the firmness of erections when coupled with sexual arousal.
