When a man is sexually stimulated, the arteries in the penis relax and widen, allowing more blood to flow into the erectile tissues. At the same time, the veins that normally carry blood away from the penis are compressed, trapping blood inside and producing an erection. Malegra 200 enhances this natural process by inhibiting the action of PDE5, an enzyme that breaks down a chemical called cyclic guanosine monophosphate (cGMP). By blocking PDE5, Malegra helps to maintain higher levels of cGMP in the penis, leading to improved blood flow and firmer erections.
