Silagra 100 mg contains sildenafil citrate, the same active ingredient found in Viagra. It is used primarily to treat erectile dysfunction (ED) in men by increasing blood flow to the ****, which helps men achieve and maintain an erection when ****ually aroused. Sildenafil citrate is a PDE5 inhibitor. It works by blocking the enzyme phosphodiesterase type 5 (PDE5), which normally breaks down cGMP (cyclic guanosine monophosphate), a molecule that helps relax the blood vessels in the ****.
