Silagra 100 mg is a prescription medication used to treat erectile dysfunction (ED) in men. Its active ingredient is Sildenafil Citrate, a phosphodiesterase type 5 (PDE5) inhibitor. Sildenafil works by increasing blood flow to the penis during sexual stimulation, helping to achieve and maintain an erection. It does not cause an erection without sexual arousal. Typically, Silagra 100 mg is taken about 30 minutes to 1 hour before sexual activity, and its effects can last up to 4–5 hours. It should be taken only once per day, with or without food. https://www.genericday.com/silagra-100-mg.html
