Due to this, adequate blood pressure is not developed to harden penile muscles. The physiological rationale behind the occurrence of this problem is inadequate blood supply in the penile region. Erectile dysfunction means that a male would find it difficult to achieve and sustain an erection sufficient for a sexual intercourse. This medication is widely applied for adult men with erectile problems, as a medically approved health condition. By delaying the function of PDE-5 for 4 hours maximum, this medication keeps penile blood vessels relaxed and blood pressure created by additional blood flow helps a person to get an erection.
The PDE-5 inhibiting capacity of Viagra helps stops this enzyme from breaking the erectile process, initiated by cGMP. While the earlier medications including injections used to help a man to get an erection in an instant, the user could not control his erection, Viagra provides an erection only when he is sexually excited. Compared to the earlier erectile dysfunction treatment methods, such as using natural herbs or using injections for the penis, use of Viagra emerged as a more secure and less complicated method. One of the major reasons behind Viagra’s overwhelming success is its recognition as the first medication that treats erectile dysfunction, a form of male sexual malfunction, in an affordable, hazardless and effective manner. Scientifically referred to as sildenafil citrate, this medication was launched as a medication to treat erectile dysfunction. Viagra is one of the most famous medication names in the history of human civilization.
