Eriacta 100 mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, which is a phosphodiesterase type 5 (PDE5) inhibitor. Sildenafil citrate, the active ingredient in Eriacta 100 mg, works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). PDE5 is responsible for the degradation of cyclic guanosine monophosphate (cGMP), a chemical messenger that helps regulate blood flow in the penis. By inhibiting PDE5, sildenafil helps to increase levels of cGMP, leading to relaxation of the smooth muscle cells in the blood vessels of the penis. This relaxation allows for increased blood flow, resulting in improved erectile function. https://www.genericday.com/eriacta-100-mg.html
