Purpose

  • Buccal delivery allows bypassing first-pass metabolism
  • Evaluating buccal mucosal permeability is necessary to assess the pharmacokinetics (PK) of active pharmaceutical ingredients (APIs) intraorally delivered using mechanistic in silico approaches
  • In vitro permeability assays were conducted using the organotypic EpiOral™ tissue model  (ORL-200, MatTek Corp., Ashland, MA) (cf. Poster #T1030-04-26)
  • A mechanistic in silico model of the EpiOral™ tissue was developed and validated in MembranePlus™ software (beta version, Simulations Plus Inc., Lancaster, CA)
  • Diffusivity (Dm) and fraction unbound (fut) in the oral mucosa of the EpiOral™ tissue were determined for 8 APIs.
