Silditop 50 mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, the same active ingredient found in Viagra. Sildenafil is a PDE5 inhibitor, which works by increasing blood flow to the penis during sexual arousal, helping men achieve and maintain an erection. Sildenafil in Silditop 50 mg works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). PDE5 breaks down cyclic GMP, a substance that relaxes the smooth muscles and dilates blood vessels in the penis.
