The optimized formulation of N-4472, N-[2-(3,5-di-tert-butyl-4-hydroxyphenethyl)-4,6-difluorophenyl]-N'-[4-(N-benzylpiperidyl)] urea, which was a poorly water-soluble drug, was developed by utilizing the complexation between N-4472 and L-ascorbic acid (VC). It was found that the formulation with Gelucire((R)) 44/14, HCO-60((R)) and sodium dodecyl sulfate provided

ABI-007 is a novel Cremophor-free, protein-stabilized, nanoparticle formulation of paclitaxel. The absence of Cremophor EL may permit ABI-007 to be administered without the premedications used routinely for the prevention of hypersensitivity reactions. Furthermore, this novel formulation permits a higher paclitaxel
