Tadacip 20 mg works by blocking the action of the PDE5 enzyme, which breaks down cyclic GMP (cGMP), a substance that helps relax the blood vessels in the penis. By inhibiting this enzyme, tadalafil allows more cGMP to accumulate, resulting in the relaxation of smooth muscles and improved blood flow to the penis. This enhanced blood flow helps men with erectile dysfunction achieve an erection in response to sexual stimulation.
