Pharmacogenomics is the tailoring of drug treatments to people's genetic make up - a kind of 'personalised medicine'.
People respond differently to medicines. Some respond effectively and their health improves. Some tend not to gain any benefits from the treatment, and some are actually damaged.
One of the most considerations that affect how well we answer drugs is our genetic make-up. So by finding out which genes control response to help drugs, medical researchers hope to develop genetic tests that could predict whether patients will respond well to a drug or will likely suffer harmful side-effects.
If several similar drugs exist which can help treat a condition, a doctor could possibly give a genetic test to recognize which drug would best suit the affected person.
This is the hope; but what's the reality? Although pharmacogenomics might be important in the medicine of the future, there are many scientific and medical obstacles to overcome before it's in routine use.
