Tadfil 20 mg contains the active ingredient Tadalafil — a PDE‑5 inhibitor used mainly to treat erectile dysfunction (ED), and sometimes pulmonary arterial hypertension (PAH) or urinary symptoms due to enlarged prostate, depending on doctor’s advice. Tadalafil relaxes smooth muscles and dilates blood vessels, allowing increased blood flow to the penis when sexually stimulated. This improved flow can help in achieving and maintaining an erection.
