Pharmacogenetics may help depressed patients get better medication faster

Anti-depressants are a finicky class of drugs that often take four tries to ensure a patient receives the right medication, the right dosage, and with few, if any, side effects.

But the growing field of pharmacogenetics is attempting to change all that, with the hope that its successes will include many other drugs down the road.
