Brand Viagra is the most well-known drug for treating erectile dysfunction in men. The drug’s effect is based on increasing blood inflow to the penis, in the presence of sexual arousal. Viagra takes effect in 30 minutes after ingestion and remains effective for 4 hours.
According to its medical properties, Viagra is a drug used to treat a form of impotence – erectile dysfunction, i.e. circulatory disturbances in the blood vessels involved in the mechanism of erection. The active ingredient of the drug is a synthetic substance called Sildenafil Citrate.
How does Viagra work?
Viagra has been known to achieve a success rate as high as 90%. Viagra works by allowing the blood vessels in the penis to relax, which then allows more blood into these vessels resulting in increased pressure. Viagra also allows the blood pressure to be maintained in the penis which results in the body’s ability to sustain an erection and enjoy a healthy sex life.
How to use?
Viagra is taken orally approximately 30- 60 minutes before engaging in sexual intercourse. Most people take a 50mg dosage once a day. Viagra can be effective in helping the body’s natural mechanisms to achieve an erection for up to 4 hours. It is best to take Viagra with water, on an empty stomach as some foods change the absorption rate of the Viagra. Viagra does not cause erections without sexual stimulation or arousal.
