Sildigra 250mg is a medication used to treat erectile dysfunction (ED) in men. It contains Sildenafil Citrate, the same active ingredient found in Viagra and other generic ED treatments. Like other Sildenafil-based medications, Sildigra 250mg works by increasing blood flow to the penis during sexual arousal. Sildenafil inhibits the enzyme phosphodiesterase type 5 (PDE5), which typically breaks down a compound called cGMP.
