Preparation and characterization of nanocapsules from preformed polymers by a new process based on emulsification-diffusion technique.

abstract：PURPOSE:Grapefruit juice (GJ) is known to increase the oral bioavailability of many CYP3A-substrates by inhibiting intestinal phase-I metabolism. However, the magnitude of AUC increase is often insignificant and highly variable. Since we earlier suggested that CYP3A and P-glycoprotein (P-gp) form a concerted barrier to...
