Definitions

  • the invention relates to increasing the bioavailability of lipophilic drugs, and more specifically, to solubilizing lipophilic drugs using bioenhancers that achieve a desired degree of efflux inhibition.
  • Water-soluble vitamin E-active polyethylene glycol esters of tocopheryl acid such as succinates were developed to provide water-soluble molecules having high vitamin E ' activity via either oral or parenteral administration.

  • TPGS molecules in which the polyethylene glycol chains have an average molecular weight (MW) of about 1000 are currently used in oral pharmaceutical applications to enhance the bioavailability of various drugs. Due to the amphiphi ⁇ c nature of TPGS 1000, incorporating TPGS 1000 into pharmaceutical formulations enhances oral bioavailability by solubilizing some hydrophobic drugs. TPGS 1000 is also believed to influence one or more transporter proteins, one example of which is P-glycoprotein (P-gp), an enzyme that acts as a cellular efflux pump. Therefore, TPGS 1000 may contribute to oral bioavailability enhancement by influencing efflux of some drugs.
  • P-gp P-glycoprotein
  • efflux inhibition results in increased oral bioavailability of certain drugs, it is also desirable in some circumstances to avoid efflux inhibition or to control the degree to which efflux inhibition occurs.
  • administration of an efflux inhibitor in a pharmaceutical formulation may result in the need for additional testing to determine whether the efflux inhibitor has an impact on the oral bioavailability (absorption, metabolism, distribution, or clearance) of other coadministered drugs or dietary substances.
  • Controlling the degree of efflux inhibition can also be desirable where a number of substances subject to efflux need to be considered. It would be an advance in the art to provide pharmaceutical formulations that contain a solubility-enhancing TPGS molecule to enhance the bioavailability of lipophilic drugs, while avoiding efflux inhibition altogether or achieving a desired level of efflux inhibition.
  • One aspect of the invention is based on the unexpected discovery that the efflux inhibition effect of TPGS varies with the molecular weight of the polyethylene glycol (PEG) portion of the molecule.
  • PEG polyethylene glycol
  • TPGS molecules having a PEG molecular weight of no more than about 600 exhibit a significant solubilizing effect when coadministered with lipophilic drugs, without exhibiting significant efflux inhibition.
  • TPGS molecules having a PEG molecular weight of at least about 3400 exhibit a significant solubilizing effect when coadministered with lipophilic drugs, without exhibiting significant efflux inhibition. Properties that provide useful solubiiizing agents without efflux inhibition characteristics will allow formulators a choice to simultaneously obtain solubilizing effects with efflux inhibition of a desired degree, or a product having solubilizing effects but lacking substantial efflux inhibition.
  • the numerical value in the TPGS designation refers to the molecular weight of the PEG from which it was made.

  • TPGS analogs were synthesized by methods similar to those used to synthesize TPGS 1000, differing only in the molecular weight of the polyethylene glycol (PEG) chain. Solutions were prepared of various known concentrations of these derivatives in water. Surface tension of these solutions were measured, and plotted against the concentration of the TPGS. These plots all showed a linear decline of surface tension with TPGS concentration, until an inflection point above which the surface tension held steady with increasing concentration of the TPGS. The concentration at this inflection point is defined as the critical miceliar concentration (CMC) of the particular TPGS in water. The following is a table of the measured CMC's versus the molecular weight of the PEG chain.
