Which is the mechanism of action of Zhewitra 20 Mg in the body?
Zhewitra 20 mg contains vardenafil hydrochloride as its active ingredient, which belongs to a class of medications known as phosphodiesterase type 5 (PDE5) inhibitors. The mechanism of action of Zhewitra 20 involves its ability to inhibit the enzyme phosphodiesterase type 5.
Here's how it works:
Erection Process: Under normal circumstances, sexual stimulation leads to the release of nitric oxide (NO) in the erectile tissue of the penis. Nitric oxide activates an enzyme called guanylate cyclase, which results in increased levels of cyclic guanosine monophosphate (cGMP).
Role of cGMP: cGMP is a signaling molecule that relaxes smooth muscle cells in blood vessels, including those in the corpus cavernosum of the penis. This relaxation allows for increased blood flow into the penis, leading to an erection.
PDE5 Inhibition: Phosphodiesterase type 5 (PDE5) is an enzyme that breaks down cGMP, thereby reducing its concentration in the penis and causing the erection to subside.
Vardenafil Action: Vardenafil in Zhewitra 20 mg inhibits PDE5, which means it blocks the action of this enzyme. By doing so, vardenafil helps to maintain higher levels of cGMP in the penis, prolonging the vasodilation and enhancing the erectile response.
In summary, Zhewitra 20 mg works by increasing the effects of nitric oxide and cGMP in the penis, leading to improved blood flow and a more sustainable erection during sexual stimulation. It's important to note that sexual arousal is still required for the medication to be effective.
