The Food and Drug Administration last week promised a quick review of Viagra, meaning it could be sold by April. Unlike injection drugs, Viagra doesn't cause erections unless the man is sexually stimulated. This drug is the most natural, normal thing you can take. Viagra was a failed heart drug investigated again after some heart patients unexpectedly reported erections. Some 10 percent of patients report mild side effects such as headache or flushing.
Apomorphine affects chemicals in the brain region associated with initiating erections.
Doctors discovered the effect in 1869, but found the drug better for poison victims because it also caused serious nausea and vomiting. Tap had planned to seek FDA approval in 1999, but Padma-Nathan said Monday that the drug works well enough that the company may act sooner. Vasomax is an oral version of a current injection drug that dilates penile blood vessels. Trials show it can help about 40 percent of men with moderate impotence. Manufacturer Zonagen Inc. is expected to seek FDA approval by year's end.
