Genome-Based Medical Choices Draw Nearer

A study of over 38,000 hypertension patients (the ALLHAT study, for Antihypertensive and Lipid Lowering Treatment to Prevent Heart Attack Trial) finds that individuals respond better to some drugs than to others, based on their personal genetics. Steve Mirsky reports.

It’s the kind of thing we can look forward to more in the coming years: personalized drug regimens based on our individual DNA.  An example of this new kind of personalized medicine is illustrated 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 patient’s genetic 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’ll 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.

This study of genetics and bp meds included over 38,000 subjects with high blood pressure in the US and Canada who are taking part in a large multicenter trial.  With personalized genomic sequencing becoming affordable 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.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
