Fildena CT 50, like other variants of Fildena, contains the active ingredient Sildenafil Citrate, which is a phosphodiesterase type 5 (PDE5) inhibitor. It is used to treat erectile dysfunction (ED) in men.

Erectile dysfunction occurs when a man has difficulty achieving or maintaining an erection that is sufficient for sexual activity. It can be caused by various factors, including physical conditions, psychological issues, or a combination of both.

The mechanism of action of Fildena CT 50 involves the following steps:

Inhibition of PDE5: When a man is sexually stimulated, the body releases nitric oxide in the erectile tissue of the penis. Nitric oxide activates an enzyme called guanylate cyclase, which increases the production of a chemical called cyclic guanosine monophosphate (cGMP).

Relaxation of Blood Vessels: cGMP relaxes the smooth muscles in the penile blood vessels, causing them to dilate and allowing increased blood flow into the penis.

Erection: The increased blood flow into the penis leads to engorgement and expansion of the erectile tissues, resulting in an erection.

However, in men with erectile dysfunction, an enzyme called PDE5 breaks down cGMP too quickly, leading to a decreased amount of cGMP in the penile tissues. As a result, the blood vessels constrict, and the erection weakens or does not occur at all.

Fildena CT 50 works by inhibiting the action of PDE5, allowing cGMP levels to increase and persist longer in the penile tissues. This sustained elevation of cGMP promotes prolonged relaxation of the blood vessels and improved blood flow to the penis, helping men achieve and maintain a firm erection during sexual stimulation.
