Mom Was Right: It Will Make You Go Blind
Sad, but apparently true.
Interesting and potentially horrendus for the drug companies. But here's where it gets screwed up and shows that the FDA is again in the drug companies' pocket.
The implication here is that older people tend to get NAOIN. But that's not true.
It is true that it is more prevalent in diabetics, but it's also true that NAOIN is equally prevalent in women and men.
U.S. health regulators on Friday said they have received more than 40 reports of a type of blindness in men taking impotence drugs, mostly involving Pfizer Inc.'s Viagra. The U.S. Food and Drug Administration said it has received about 38 reports of the rare condition among users of Viagra, four reports of blindness among users of Eli Lilly and Co.'s Cialis and one report of the condition in men talking Levitra, made by GlaxoSmithKline Plc.
Pfizer said outside of clinical trials, Viagra has been used by more than 23 million men worldwide over the past seven years. It said reports are extremely rare of visual loss due to the condition known as non-arteritic anterior ischemic optic neuropathy (NAION).
Interesting and potentially horrendus for the drug companies. But here's where it gets screwed up and shows that the FDA is again in the drug companies' pocket.
The FDA's Cruzan said NAOIN is not uncommon for people of the age that use the impotence drugs, who have conditions like heart conditions, diabetes and heart disease.
The implication here is that older people tend to get NAOIN. But that's not true.
Non-arteritic AION can occur at any age - no age is immune from non-arteritic AION - although most often patients are middle aged and elderly, about 10% of the patients are young (i.e. under the age of 45 years - our youngest patient has been 11 years old);44 thus, the prevalent impression that non-arteritic AION is a disease of the elderly only and does not occur in the young persons is not correct.
It is true that it is more prevalent in diabetics, but it's also true that NAOIN is equally prevalent in women and men.
