Eriacta 100 is a medication that contains sildenafil citrate as its active ingredient. Sildenafil is a phosphodiesterase type 5 (PDE-5) inhibitor, and it is commonly prescribed for the treatment of erectile dysfunction (ED). Erectile dysfunction is a condition in which a man is unable to achieve or maintain an erection sufficient for sexual activity.

Here's how Eriacta 100 (sildenafil) works and why it is prescribed for ED:

Phosphodiesterase type 5 (PDE-5) Inhibition: Eriacta 100 mg tablet works by inhibiting the action of PDE-5, an enzyme that breaks down cyclic guanosine monophosphate (cGMP). cGMP is a chemical messenger that plays a crucial role in the dilation of blood vessels, including those in the penis.

Enhancement of Nitric Oxide: When a man is sexually stimulated, the release of nitric oxide (NO) in the erectile tissue of the penis leads to increased levels of cGMP. This, in turn, causes relaxation of the smooth muscles in the blood vessels, allowing blood to flow into the penis and create an erection.

Increased Blood Flow to the Penis: By inhibiting PDE-5, Eriacta 100 helps to maintain higher levels of cGMP, leading to prolonged relaxation of the smooth muscles and increased blood flow to the penis. This improved blood flow facilitates the achievement and maintenance of an erection during sexual arousal.

Eriacta 100, like other sildenafil-containing medications, is generally effective in treating ED caused by various factors, such as physical or psychological issues. However, it's important to note that Eriacta 100 does not cause spontaneous erections; sexual arousal and stimulation are still necessary for the medication to be effective.
