The active component in Vidalista 5 mg is Tadalafil, which is a PDE5 inhibitor. This class of drugs works by blocking the enzyme phosphodiesterase type 5 (PDE5), which normally breaks down a molecule called cGMP. By preventing this breakdown, Tadalafil helps to maintain higher levels of cGMP, which relaxes the muscles in the blood vessels of the penis, increasing blood flow and enabling an erection when sexually stimulated.
