Malegra Oral Jelly is actively composed of an ingredient, which is the PDE5 enzyme antagonist. This enzyme blocks the blood flow to the male organ resulting in ED. But using this oral jelly stops PDE5 from degrading the vasodilator cGMP and relaxes the smooth muscles in your body. Later, as the vasodilation continues, nitric oxide augments higher blood supply all over the body. The blood flows towards the male reproductive organ increases and helps achieve the desired firm erection. Sexual arousal is essential to attain an erection.
