Suhagra 100 mg is a medication used to treat erectile dysfunction (ED) in men. It contains Sildenafil Citrate, the same active ingredient as in Viagra, and works by increasing blood flow to the penis during sexual stimulation, which helps achieve and maintain an erection. Suhagra 100 mg is a PDE5 inhibitor, which means it works by blocking the enzyme PDE5 that can restrict blood flow in the penis. By inhibiting this enzyme, Suhagra helps to relax the blood vessels, allowing more blood to flow into the penis, leading to an erection.
