Fildena 150 mg is prescribed for men who have difficulty achieving or sustaining an erection. It helps address the physical aspect of ED, allowing for improved blood flow to the penis. However, it does not cure the underlying causes of ED. Sildenafil, the active ingredient in Fildena 150 mg, inhibits the enzyme PDE5, which is responsible for breaking down cyclic guanosine monophosphate (cGMP). cGMP is a chemical that promotes the relaxation of blood vessels in the penis, leading to increased blood flow. https://www.flatmeds.com/product/fildena-150-mg/
