• Viagra originally developed to treat angina sufferers was later discovered to help the cause of erectile dysfunction. Uprima is a fairly new revolutionary drug used to treat Erectile Dysfunction also.
  
  
• Viagra increases blood flow to the penis to facilitate sexual arousal and erection. The erection goes away when the sexual encounter is over. Viagra works in about 30 minutes and lasts for at least 4 hours. Uprima brings a man to arousal three times faster than Viagra. Uprima facilitates the erection in 18 minutes as it is placed under the tongue.
  
  
• When a man is sexually aroused, certain tissues in his penis relax. This allows large amounts of blood to flow in, thus producing an erection. Viagra helps by elevating the levels of the chemical that causes the tissues to relax. Uprima acts on the central nervous system. It facilitates the sending from the hypothalamus, of the sign that increases the sanguine flow in the sexual organ, thus the erection takes place.
