The effectiveness of Aurogra in increasing potency is due to sildenafil citrate, which is the active substance of this drug. Sildenafil citrate, absorbed from the gastrointestinal tract, enters the systemic circulation, which reaches the smooth muscle cells of the penis. When a man has sexual arousal, this substance "helps" nitric oxide to expand the vessels of the penis and increase blood flow to it. This creates a powerful erection that allows a man to perform sexual intercourse. The undeniable advantage of Aurogra is the absence of the risk of spontaneous erections after taking the drug, as you can see for yourself by reading the reviews of men about these tablets.
