Fildena 120 mg is a medication that contains sildenafil citrate as its active ingredient. Sildenafil citrate is a phosphodiesterase type 5 (PDE5) inhibitor used for the treatment of erectile dysfunction (ED) in men.
When a man is sexually stimulated, certain chemical signals are released in the body that result in the relaxation of the smooth muscles in the blood vessels of the penis. This relaxation allows for increased blood flow into the penis, leading to an erection.
In individuals with ED, the enzyme PDE5 breaks down cyclic guanosine monophosphate (cGMP), which is responsible for regulating the relaxation of the smooth muscles and blood flow in the penile tissues. This can result in insufficient blood flow into the penis, leading to difficulty in achieving or maintaining an erection.
Fildena 120 mg works by inhibiting the enzyme PDE5. By blocking PDE5, it helps prevent the breakdown of cGMP, allowing for increased levels of cGMP in the penile tissues. This, in turn, promotes the relaxation of the smooth muscles in the blood vessels of the penis, enhances blood flow, and facilitates the ability to achieve and maintain an erection when sexual stimulation occurs.
