Tadalafil, the active ingredient in Tadarise Pro, belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. It works by inhibiting the PDE5 enzyme, which breaks down a chemical called cyclic guanosine monophosphate (cGMP) that relaxes blood vessels. By preventing this breakdown, Tadalafil allows for increased levels of cGMP, leading to improved blood flow to the penis during sexual arousal.
