Silday 100 Tablet (Sildenafil) inhibits phosphodiesterase type 5 (PDE5), an enzyme that breaks down cyclic GMP. Increased cyclic GMP levels relax smooth muscles in the blood vessels of the penis, leading to improved blood flow and facilitating erection in the case of ED. In PAH, this mechanism improves blood flow in the pulmonary arteries, reducing blood pressure.
