Uprima (apomorphine hydrochloride) is a new medical treatment for the management of erectile dysfunction. Uprima is a central initiator that works by stimulating an erection through mechanisms originating in the brain. It is almost as effective as Viagra and has the added advantage of being faster to act since it is absorbed under the tongue and thus gets into the blood stream quicker. It usually works within five minutes of taking it, as distinct from over an hour or more that it takes Viagra to click in. Side Effects: Generally mild and transient. As with Viagra, the most common side effects are nausea, headache and dizziness.
