Vidalista is primarily prescribed to treat Erection concerns, a condition that affects many men, particularly as they age. The active ingredient, Tadalafil, belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. By inhibiting PDE5, Tadalafil helps relax the muscles in the blood vessels of the penis, allowing for improved blood flow and enabling an erection in response to sexual stimulation. Vidalista is also used in the treatment of BPH (benign prostatic hyperplasia) and, less commonly, pulmonary hypertension.
