Inhibition of intestinal P-glycoprotein might enhance the absorption of orally administered P-
glycoprotein substrate drugs. We show here a 10-fold increased oral bioavailability of
paclitaxel in mice treated with the P-glycoprotein blocker SDZ PSC 833. These results
encourage further research on the development of a clinically useful oral formulation of
paclitaxel.
