The WSJ reports, some researchers are now trying to use grapefruit juice to their advantage.
An enzyme that lives in the gut, charmingly named CYP3A4, breaks down drugs before they enter the bloodstream.
Grapefruit juice has a compound that temporarily gets rid of CYP3A4 — which allows more of a drug to enter the bloodstream. That can be a bad thing in some cases. Patients shouldn’t take statins (such as Pfizer’s Lipitor or Merck’s Zocor) with grapefruit juice, because doing so can cause the drug to build up to unhealthy levels in the body.
It’s too early to tell how far this sort of thing might go, and standardizing grapefruit juice as part of a drug regimen could be tricky. But some docs think the grapefruit effect could ultimately allow patients to take lower doses of drugs.

If we can lower the costs of those by 50%, you’re talking about hundreds of millions of dollars saved.”
