Vidalista is a prescription-based medicine for treating Erectile Dysfunction (ED) or impotence. Impotence is a sexual dysfunction in which a man is incapable of getting a firm erection due to a lack of blood circulation in the penis. Vidalista 60 contains FDA-approved Tadalafil, which is a Phosphodiesterase type 5 inhibitor (PDE5). Tadalafil helps a man get an erection by increasing the blood flow in the penile area. Centurion Laboratories manufactures Vidalista and its various strengths.
