Zenegra 100 mg is a medication containing Sildenafil Citrate, primarily used to treat erectile dysfunction (ED) in men. Manufactured by Alkem Laboratories, it belongs to the class of phosphodiesterase type 5 (PDE5) inhibitors. Sildenafil works by inhibiting the PDE5 enzyme, leading to increased levels of cyclic GMP. This results in the relaxation of smooth muscle in the blood vessels of the penis, enhancing blood flow and facilitating erections during sexual stimulation.
