Malegra-Gold 50 mg is a prescription medication primarily used to treat erectile dysfunction (ED) in men, a condition characterized by the inability to achieve or maintain a firm erection suitable for sexual activity. This medication contains caverta-25-mg, the same active ingredient found in Viagra, and works by enhancing blood flow to the penis during sexual stimulation. As a phosphodiesterase type 5 (PDE5) inhibitor, Sildenafil helps relax the smooth muscles in the blood vessels of the penis, thereby allowing for improved erectile function when a man is sexually aroused.
