i think what is delaying the discovery of an efficacious curative antiretroviral agent is improperlly understood pathophysiology of the hiv virion.

Instead of making pills with 'acceptable' levels of a carcinogen, why doesn't Pfizer insist that its pills contain ZERO levels of EMS? Is EMS a byproduct of the manufacturing process or is it a contaminant? Why settle for 'safe' levels of EMS(which may not be safe) in a medicinal product? Having 'safe' levels of a carinogen in a medicine is like saying defective steering wheels in cars are ok in 1% of all cars produced by a company, or 1 plane crash out of 1000 flights is ok.

I've been on Viracept almost 5 years now. So far I have had no problems. I'm also on Ziagen and Didanosine. It has been a good combination for me. I enjoy getting the updates from AIDSmeds. Thank you.

I should point out that while the impurity in Viracept has been found to be a potential carcinogen -- meaning that it was found to be potentially cancerous in animal studies at high doses -- there is no data to suggest that HIV-positive people taking the drug have, in fact, experienced a higher rate of certain cancers. In effect, the warning from Pfizer is precautionary. -Tim Horn, Senior Editor, AIDSmeds.com

I would appreciate if you could either direct me or send me more specific info regarding the type of cancer viracept is causing and if there is any testing protocols I should be aware of. I took it throughout my entire pregnancy, not to mention for many years before. Thank God my son is HIV negative but I always worried about something like this. Thank You, Mary
