Medicine gets personal

From the NY Times:

A new drug for acne, Aczone, was approved in July, but with a catch.
The Food and Drug Administration said it would require that patients
first be tested for an enzyme deficiency that could put them at risk of
developing anemia from the drug.

age of personalized medicine is on the way. Increasingly, experts say,
therapies will be tailored for patients based on their genetic makeup
or other medical measurements. That will allow people to obtain drugs
that would work best for them and avoid serious side effects.

Yes, but it creates headaches for doctors and gives pharmaceutical companies the shimmies. It may narrow the market or create a lot of complexity, impediments to profits.
