Zhewitra 20 mg contains Vardenafil, which is a phosphodiesterase type 5 (PDE5) inhibitor. It works by increasing blood flow to the penis, which helps men with erectile dysfunction (ED) achieve and maintain an erection when sexually stimulated.

Here’s how Zhewitra 20 mg works in detail:

Inhibition of PDE5 enzyme: The PDE5 enzyme is responsible for breaking down a molecule called cyclic GMP (cGMP), which helps relax the smooth muscle in the blood vessels of the penis. By inhibiting PDE5, Vardenafil allows cGMP to accumulate, promoting smooth muscle relaxation.

Increased blood flow: As a result of the increased cGMP, the blood vessels in the penis dilate, leading to improved blood flow. This enhanced circulation is what helps to achieve and sustain an erection when a man is sexually aroused.

Onset of action: Zhewitra 20 mg typically begins working within 30 minutes to 1 hour after taking it, and its effects can last for up to 4-6 hours, providing a window of time for sexual activity.

Sexual stimulation required: It’s important to note that Zhewitra does not cause an erection on its own. Sexual arousal is still necessary for the medication to work effectively.

Zhewitra 20 mg is effective in treating ED, but it’s important to follow dosage instructions and consult with a healthcare provider for personalized guidance. Avoid excessive alcohol or fatty meals before taking the medication, as they may reduce its effectiveness.
