Aurogra contains Sildenafil Citrate as its active ingredient. Men buy Aurogra 100 mg online with a doctor’s prescription to handle ED. The medication works by promoting sufficient blood flow to the penile area. It happens due to the effect of the drug on the production of nitric oxide, which relaxes the smooth muscles of the cavernous bodies of the penis thus giving way to the blood, which is needed to get a strong and lasting erection. Aurogra stays in your body for 5-6 hours after being taken. So take this tablet 30 minutes before your sexual intercourse.
