Penegra 100mg contains the active ingredient sildenafil. It belongs to a group of medicines PDE5 inhibitors.
During sexual arousal, a molecule called nitric oxide (NO) is released within the penis. This increases levels of another molecule called the cGMP. cGMP causes the smooth muscles inside the penis to relax.
As a result, the blood vessels open wider allowing for blood to flow. It causes the corpus cavernosa (the spongy tissue in the penis) to swell. Thus, the penis becomes larger and stiff enough for sexual intercourse.
However, an enzyme called PDE5 breaks down cGMP molecules, ending the erection. PDE5 inhibitors such as sildenafil stop PDE5 from working too quickly. It prevents the cGMP breakdown. Hence, the action of nitric oxide is enhanced, promoting blood flow. This helps prolong the erection, making it firm enough for intercourse.
Note that Penegra 100mg itself directly does not cause an erection. It helps the body respond better to sexual arousal. Sildenafil has no effect where sexual stimulation is absent.
