Vigora 100 mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, the same active ingredient found in Viagra. Sildenafil helps improve blood flow to the penis, which aids in achieving and maintaining an erection during sexual activity. Sildenafil (100 mg) works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). This enzyme normally breaks down cyclic GMP, a molecule that helps relax blood vessels in the penis and allows blood to flow more easily. https://www.flatmeds.com/product/vigora-100-mg/
