Though Fildena and Revatio both contain sildenafil, they are marketed under different names and may have slight differences in formulation or branding. Revatio is specifically approved for treating PAH, whereas Fildena is often sold as a generic alternative for Sexual impotence. Both medications function the same way in treating PAH by helping relax and widen the blood vessels in the lungs. However, Fildena should only be used for PAH under a doctor’s guidance, as the precise dosage is critical for effective treatment and avoiding side effects.
