The active ingredient in Suhagra 25 mg, Sildenafil Citrate, belongs to a class of drugs known as PDE5 inhibitors (phosphodiesterase type 5 inhibitors). PDE5 is an enzyme found in the penis, which plays a role in regulating blood flow. When a man is sexually aroused, nitric oxide is released in the penis, leading to the production of cyclic GMP, a molecule that causes the blood vessels in the penis to relax and dilate. PDE5 breaks down cyclic GMP, limiting blood flow to the penis. By inhibiting PDE5, Sildenafil Citrate allows cyclic GMP to accumulate, leading to enhanced blood flow and helping men achieve an erection.
