Caverta 50 mg contains Sildenafil Citrate, which works by inhibiting the enzyme PDE5 in the body. PDE5 normally breaks down cyclic GMP, a compound that helps relax the smooth muscles in blood vessels and increases blood flow. By inhibiting this enzyme, Caverta 50 mg helps the body maintain higher levels of cyclic GMP, leading to better relaxation of the blood vessels in the penis. This allows more blood to flow to the area when sexually aroused, resulting in an erection.
