Tadarise 10 mg contains Tadalafil, a drug that inhibits the enzyme phosphodiesterase type 5 (PDE5). Under normal circumstances, PDE5 can break down a substance called cyclic guanosine monophosphate (cGMP), which is responsible for relaxing the smooth muscles in the penis and allowing blood to flow more freely. When a man is sexually stimulated, nitric oxide is released, which activates the production of cGMP, helping to achieve and sustain an erection.
