Vidalista 20 mg is a prescription-based medicine for the treatment of Erectile Dysfunction (ED) or impotence. Impotence is a sexual dysfunction in which a man is unable to get a firm erection due to a lack of blood circulation in the penis. Vidalista 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. Fildena 200 treats both psychological and physical causes of erectile dysfunction. Psychological causes like anxiety, depression, relationship problems etc. and physical causes like narrowing of the blood vessels going to the penis, high blood pressure, high cholesterol, diabetes, hormonal problems, surgery or injury etc. can disrupt a healthy sexual life.
