The Fildena 50 A drug called sildenafil is intended to treat male erectile dysfunction (ED). Sildenafil citrate, its active component, is classified as a phosphodiesterase type 5 (PDE5) inhibitor. Its main mode of action is its capacity to increase blood flow to the penile area during sexual stimulation, which makes it easier to obtain and maintain an erection.
Nitric oxide (NO) is released in the erectile tissue as a result of a series of biochemical processes that take place in the body when a man becomes sexually aroused. Cyclic guanosine monophosphate (cGMP) levels rise as a result of this NO activating the guanylate cyclase enzyme. The smooth muscles that line the blood arteries in the penis relax when cGMP levels are elevated, causing the vessels to widen and enhance blood flow.
