Fildena is a brand of medication that contains sildenafil citrate as its active ingredient. Sildenafil citrate belongs to a class of medications known as phosphodiesterase type 5 (PDE5) inhibitors. The mechanism of action of Fildena revolves around its effects on the smooth muscle tissue and blood vessels, particularly in the penis. Here’s a detailed explanation of how Fildena (sildenafil citrate) works:
Relaxation of Blood Vessels: When a man becomes sexually aroused, nitric oxide (NO) is released in the erectile tissue of the penis. Nitric oxide activates an enzyme called guanylate cyclase, which increases levels of cyclic guanosine monophosphate (cGMP).
Increased cGMP Levels: Cyclic GMP causes the smooth muscles in the arteries of the penis to relax, allowing blood to flow into the erectile tissue and produce an erection. This relaxation of smooth muscles and dilation of blood vessels in the penis are essential for achieving and maintaining an erection.
Inhibition of PDE5 Enzyme: Sildenafil citrate in Fildena works by inhibiting the action of phosphodiesterase type 5 (PDE5) enzyme. PDE5 is responsible for breaking down cGMP, which regulates blood flow in the penis. By inhibiting PDE5, sildenafil allows cGMP levels to remain elevated, prolonging the dilation of blood vessels and enhancing erectile function.
Onset and Duration: Fildena is typically taken about 30 minutes to 1 hour before anticipated sexual activity. It reaches its peak blood concentration within 30 to 120 minutes after oral administration. The effects of Fildena can last up to 4 to 6 hours, during which time a man can achieve and maintain erections with sufficient sexual stimulation.
Sexual Stimulation Required: It’s important to note that Fildena (sildenafil citrate) does not automatically cause an erection. Sexual arousal and stimulation are necessary to activate the release of nitric oxide and initiate the cascade of events leading to erection.
Overall, Fildena (sildenafil citrate) is effective in treating erectile dysfunction (ED) by enhancing the natural physiological processes involved in achieving an erection. It has been extensively studied and proven to be safe and effective for many men with ED, although it may not be suitable for everyone. It's important to use Fildena as prescribed by a healthcare provider to ensure optimal results and minimize the risk of side effects.
