Silagra 50 mg belongs to the PDE5 inhibitor class of medications. It works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which breaks down cGMP in the penis. This inhibition increases cGMP levels, leading to the relaxation of smooth muscles and the dilation of blood vessels in the penis. As a result, more blood flows into the penis, aiding in the ability to achieve and maintain an erection during sexual activity.
