Vidalista, containing the active ingredient Tadalafil, is a medication primarily used to treat erectile dysfunction (ED) in men. It belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. Here's how Vidalista works:
Mechanism of Action: Vidalista works by inhibiting the action of the enzyme phosphodiesterase type 5 (PDE5). This enzyme is found in the smooth muscle cells lining the blood vessels in the penis. By inhibiting PDE5, Vidalista prevents the breakdown of cyclic guanosine monophosphate (cGMP), a chemical messenger involved in the erectile process.
Elevation of cGMP Levels: When a man becomes sexually aroused, nitric oxide (NO) is released in the erectile tissue of the penis. Nitric oxide stimulates the production of cGMP, which causes the smooth muscles in the blood vessels of the penis to relax and dilate. This relaxation allows blood to flow into the erectile tissue, resulting in an erection.
Enhanced Blood Flow to the Penis: By inhibiting PDE5 and preventing the breakdown of cGMP, Cenforce helps to maintain higher levels of cGMP in the erectile tissue. This leads to prolonged relaxation of the smooth muscles in the blood vessels of the penis and increased blood flow into the erectile tissue, facilitating the achievement and maintenance of an erection.
Response to Sexual Stimulation: It's important to note that Vidalista does not cause spontaneous erections. Sexual arousal and stimulation are still necessary to trigger the release of nitric oxide and initiate the production of cGMP. Vidalista enhances the body's natural response to sexual stimulation by prolonging the effects of cGMP and improving blood flow to the penis.
Onset and Duration of Action: Vidalista typically starts working within 30 minutes to an hour after ingestion, although the onset of action may vary from person to person. The effects of Vidalista can last up to 36 hours after ingestion, providing a longer window of opportunity for sexual activity compared to some other medications used to treat erectile dysfunction.
