Fildena Chewable 100 mg contains the active ingredient sildenafil citrate, which belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. The mechanism of action of Fildena Chewable 100 mg is similar to other PDE5 inhibitors like Viagra.
During sexual arousal, the release of nitric oxide (NO) in the corpus cavernosum of the penis leads to the activation of an enzyme called guanylate cyclase. This enzyme increases levels of cyclic guanosine monophosphate (cGMP), which relaxes the smooth muscles in the blood vessels of the penis, allowing them to dilate and increase blood flow to the erectile tissue.
However, the enzyme phosphodiesterase type 5 (PDE5) breaks down cGMP, leading to a reduction in blood flow and the loss of the erection. By inhibiting PDE5, Fildena Chewable 100 mg helps to maintain higher levels of cGMP in the penis, promoting prolonged vasodilation and enhancing erectile function.
In summary, Fildena Chewable 100 mg works by increasing blood flow to the penis by inhibiting PDE5, which allows for improved erectile function during sexual stimulation.
