Viagra: Bring Your Sexual Health Back In Track.
In the history of the pharmaceutical industry, no drug has ever received such rave review and success as Viagra or Sildenafil citrate did. After it received approval on March 27, 1998 from the U.S. Food and Drug Administration, the drug received widespread popularity as it proved to be an effective drug for the treatment of sexual health problem in men called erectile dysfunction (ED) or impotence.
ED is generally a feeble condition of penile muscle and man suffering from it could not get or maintain penis erect enough for the process of sexual intercourse. It is very important to treat ED on time because it may lead to low self-esteem, sexual failure anxiety, and depression, stress and guilt and relationship conflicts.
Use of Viagra gives relief to men suffering from ED. Being the first marketed anti-ED drug, Viagra is also referred as king medicine for ED. It is an oral prescription medicine that not only helps a man gets an erection but also helps in maintaining it throughout the process of intercourse.
Viagra comes under the class of drug called phosphodiesterase inhibitors, it manipulates and blocks an enzyme called phosphodiesterase-5 (PDE-5), and helps the smooth muscles in the penis to get relaxed and widen, and that allows more blood to flow to the penis resulting in faster and easier erection.
