Fildena 100 mg contains the active ingredient sildenafil citrate, which belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. Fildena 100 mg works by influencing blood flow to the penis through a series of physiological mechanisms. Here's how it works:
Inhibition of PDE5 Enzyme: When a man is 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).
Smooth Muscle Relaxation: Increased levels of cGMP cause the smooth muscles in the penile arteries and corpus cavernosum (erectile tissue) to relax. This relaxation allows blood to flow more freely into the penis, leading to an erection.
Prevention of cGMP Breakdown: The enzyme phosphodiesterase type 5 (PDE5) is responsible for breaking down cGMP, thereby reducing its effects on smooth muscle relaxation. Sildenafil citrate, the active ingredient in Fildena 100 mg selectively inhibits PDE5, leading to increased levels of cGMP and prolonged relaxation of smooth muscle tissue in the penis.
Enhanced Blood Flow: By inhibiting PDE5, Fildena 100 mg facilitates increased blood flow to the penis during sexual stimulation. This improved blood flow is crucial for achieving and maintaining an erection that is sufficient for sexual activity.
Erection Maintenance: Fildena 100 mg helps to sustain an erection by maintaining the levels of cGMP necessary for smooth muscle relaxation throughout sexual activity. It does not directly cause an erection but enhances the body's natural response to sexual stimulation.
Overall, Fildena 100 mg improves erectile function by enhancing the natural physiological processes involved in penile erection. It acts selectively to promote smooth muscle relaxation and increase blood flow to the penis, ultimately facilitating the achievement and maintenance of an erection during sexual activity. It's important to note that Fildena 100 mg requires sexual arousal to be effective and does not cause spontaneous erections.
