Caverta 50 mg is a medication used to treat erectile dysfunction (ED) in men. Its active ingredient is Sildenafil citrate, which belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Sildenafil works by increasing blood flow to the penis during sexual arousal, helping to achieve and maintain an erection. Sildenafil inhibits the enzyme PDE5, which normally breaks down cGMP, a molecule that relaxes smooth muscles in the penis.
