Tadalista 20 mg , also known as tadalafil , belongs to the PDE5 inhibitor drug class. It is necessary to explain the physiological mechanism of erection in order to comprehend how the drug functions.
After sexual arousal, nitric oxide is released into the hollow body of the penis. Cyclic GMP, or cGMP, is generated by the enzyme granulate cyclase following the release of nitric oxide activity. The smooth muscles in the lumen relax as a result of interactions with cyclic GMP. An erection can result from enough blood entering the penile region as a result.
