Vidalista 10 mg is a medicine used to treat erectile dysfunction (ED). It contains Tadalafil (Cialis) and works as a PDE5 inhibitor, which helps relax blood vessels in the penis. Erectile dysfunction means difficulty in getting or keeping an erection, often caused by physical or psychological reasons. An erection happens when blood flows into the penis. This occurs because blood vessels supplying the penis widen, increasing blood flow, while vessels that drain blood narrow to keep the blood in. When a man becomes sexually excited, his body releases nitric oxide in the penis. This triggers the production of cGMP, a chemical that controls the opening and closing of blood vessels, allowing the penis to fill with blood and produce an erection.
