Tadacip 20 mg works by inhibiting the enzyme PDE5. When sexual stimulation occurs, the body naturally releases nitric oxide, which activates the enzyme guanylate cyclase. This increases the levels of cyclic GMP, which relaxes the smooth muscles in the penis and allows blood vessels to dilate. By inhibiting PDE5, Tadacip 20 mg helps maintain higher levels of cyclic GMP, leading to increased blood flow to the penis and improving the ability to get and keep an erection.
