Fildena is a medication that contains sildenafil citrate, a phosphodiesterase type 5 (PDE5) inhibitor. It is commonly used to treat Erectile disorder, but its role in treating Pulmonary Arterial Hypertension is equally important. By inhibiting PDE5, sildenafil helps relax the blood vessels in the lungs, allowing blood to flow more easily and reducing the pressure in the pulmonary arteries. This can significantly improve the patient's exercise capacity and quality of life.
