2,000 Viagra headlines in 3 months - 69 Viagra deaths caused possible by treatment for impotence / erectile dysfunction

bullet

Viagra may cause a rare form of blindness - risk small with very few cases among 23 million users - first reports in 2005. Possible risk of blindness from non-arteritic ischaemic optic neuropathy. This is a rare condition in which blood supply is reduced to the optic nerve causing permanent nerve damage, and research workers at the University of Minnesota believe they have detected a cluster of cases of blindness from this cause in men who have taken Viagra. The US Food and Drug Administration has also identified 50 men with blindness who have taken Viagra, but who also had diabetes and heart disease. However these problems with blindness need to be seen in the context of 23 million users, most of which have experienced significant benefit to their sex lives, and the fact that blindness is a known risk in those with both diabetes and cardiovascular disease.

bulletCialis may rival Viagra as a treatment for erectile dysfunction. The launch of Viagra, the world's first treatment for impotency was an instant success. Now, Lilly ICOS has tapped into the demand for Viagra with Cialis, Viagra's first direct competitor, and there is more to come. Cialis has key advantages over Viagra and could develop blockbuster status. Cialis is a joint venture between Eli Lilly and ICOS. Cialis is available on prescription in the UK, Germany, Denmark, Finland, Sweden and Australia. Cialis has yet to be approved in the US. Viagra works for roughly four hours with an hour's delay. Cialis starts working faster than Viagra, sometimes in 16 minutes, and lasts 24 hours. In France, it has been dubbed 'Le Weekend' pill. Unlike Viagra, Cialis does not interact with with food or alcohol - Viagra is best taken on an empty stomach. Side effects of Cialis seem similar to Viagra eg headaches and indigestion. GlaxoSmithKline/Bayer's Levitra is expected to launch in 2003. Pfizer is trying to block US launches of Cialis and Levitra, but similar legal action in Europe failed. Various sources February 2003.
bulletViagra may be causing a small number of deaths in men with heart disease by causing platelets in the blood to stick together - clumping of platelets is important in causing heart attack and stroke. Viagra increases a compound in cells called cyclic guanosine monophosphate, or cGMP. Majority of deaths associated with the 50 mg Viagra dose. Viagra deaths seem to be due to cardiovascular causes, 66% within 4-5 hours of taking Viagra in men less than 65 years of age, and who had no reported cardiac risk factors - Viagra study by Dr. Xiaoping Du of the University of Illinois at Chicago - Cell Journal January 2003
bulletViagra does not damage sight - except rarely in those with damaged optic blood vessels. Viagra can change vision in some people - who see a blue tinge which wears off several hours after Viagra use. Viagra study by Dr Tim McCulley, assistant professor of ophthalmology at Irvine - Opthalmogica Journal January 2003
bulletTwo new drugs, Cialis and Levitra, may soon challenge Viagra. Cialis is approved in Europe, and lasts up to three times longer than Viagra, up to 36 hours. And Levitra works about twice as fast as Viagra, in 20 minutes. Both new drugs have fewer side effects than Viagra. January 2003
bulletAs I predicted several years ago, illegal seizure of black market Viagra is now common. Viagra is on sale in many nightclubs, where it is often used with ecstasy. January 2003
