Info about Uprima
How does Uprima work?
Uprima is different to Viagra, Levitra or Cialis in that it dissolves under the tongue and is therefore ideal for people who find it hard to swallow. It also brings about erections in a different way - via the brain rather than at the penis directly. Uprima is available in 2mg and 3mg tablets.
Uprima contains the active ingredient apomorphine hydrochloride, which is a type of medicine known as a dopamine agonist. It works by enhancing the nerve signals that cause an erection.
An erection is produced via a complex chain of events. The process is started with sexual stimulation from sight, smell, sound or touch. This causes nerve signals to be sent from the brain to the penis, which in turn cause the blood vessels in the penis to relax and widen. This allows the penis to fill with blood and makes it become erect.
It does this by mimicking the action of dopamine, which is a natural chemical called a neurotransmitter. Neurotransmitters are involved in sending signals along nerves. They act on special receptor sites in the nervous system to produce their effects. Dopamine acts on receptors called dopamine receptors, and this causes nerve signals with various effects to be sent. When dopamine acts on receptors in an area of the brain called the hypothalamus, it causes the nerve signals that produce an erection to be sent to the penis.
Apomorphine mimics the erection-producing effect of dopamine by stimulating the same dopamine receptors in the hypothalamus. This enhances the effect of natural dopamine that is produced as a result of sexual stimulation. The nerve signals to the penis are enhanced, and this results in blood entering the penis, ultimately causing it to become rigid and erect.
As apomorphine enhances the action of dopamine in producing an erection, it will only work once sexual stimulation has occurred. It does not increase sex-drive (libido) and is not an aphrodisiac. The sublingual tablet dissolves under the tongue, where it immediately enters the bloodstream, causing an erection in most sexually stimulated men in about 20 minutes.
Warning!
There should be a minimum of eight hours between doses of Uprima. You should drink a small amount of water before taking this medicine to help it to dissolve under the tongue. The tablet should then be placed under the tongue and allowed to dissolve. If any of the tablet remains after 20 minutes it may be swallowed.
This medicine may uncommonly cause fainting. People normally experience warning symptoms of this, such as nausea, vomiting, pallor, sweating, hot flushes and dizziness or lightheadedness. If you experience these symptoms, you should not attempt to stand up - lie down and raise your legs until the symptoms pass. This medicine may cause dizziness and lightheadedness. For this reason you should not drive or operate machinery for at least two hours after taking the medicine, or until any symptoms pass. If this medicine is taken with alcohol there is an increased risk of a drop in blood pressure that might make you feel dizzy. In addition, alcohol can impair sexual performance.
