This is Scientific Americans' 60-Second Science. I'm Steve Mersky. Got a minute?

It’s the kind of thing we can look forward to more in the coming years: Personalized drug regimens based on our individual DNA1. The example of this new kind of Personalized medicine is illustrated2 by a study in the January 23rd issue of the journal of the American Medical Association. Researchers found that hypertension patients had better results with different drugs depending on the patients' genetic3 profiles. Currently, for the most part doctors will put people with high blood pressure on a standard BP medication and see if it works. If it doesn’t,/ they will try another drug until this trial and error system finds a good one. But genetic profiling could let physicians know immediately which patient will respond to which drug. The study of genetics and BP meds included over 38 thousand subjects with high blood pressure in the US and Canada who are taking part in a large multicenter trial. With Personalized genomic sequencing becoming affordable4 in the next few years. Many of us should finally know in advance not just our risks for disease but what medications will be most effective.

Thanks for the minute for Scientific Americans' 60-Second Science. I'm Steve Mersky.
