Malegra 100 mg works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). PDE5 breaks down a molecule called cyclic GMP, which helps relax blood vessels in the penis. When PDE5 is inhibited, the levels of cyclic GMP increase, allowing the blood vessels to relax, leading to improved blood flow to the penis. As a result, men can achieve a firm and sustained erection when ****ually stimulated.
