Silagra 100 mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, which is a phosphodiesterase type 5 (PDE5) inhibitor. Sildenafil works by increasing blood flow to the penis during sexual stimulation, helping men achieve and maintain an erection. The recommended dose of Silagra is typically 50 mg taken as needed, approximately 30 minutes to 1 hour before anticipated sexual activity.
