Sildenafil is a phosphodiesterase (PDE-5) inhibitor. The relaxing of the blood vessel muscles in the male reproductive region results in improved blood flow and alleviation of erectile dysfunction. By increasing serotonin levels in the brain, sildenafil, a selective serotonin reuptake inhibitor (SSRI), improves control and lengthens the ejaculation process.

Phosphodiesterase type 5 (PDE5) in the corpus cavernosum is unable to break down cyclic guanosine monophosphate (cGMP) when Aurogra 100 is injected. Nitric oxide (NO), which binds to guanylate cyclase receptors, is thus released in greater amounts by the male corpus cavernosum. Healthy erections are prolonged and supported by these secondary processes.
