  • Title: Sublingual administration of Delta9-tetrahydrocannabinol/beta-cyclodextrin complex increases the bioavailability of Delta9-tetrahydrocannabinol in rabbits.

    Abstract:
    The bioavailability of Delta(9)-tetrahydrocannabinol (THC) was determined after its sublingual administration as solid THC/beta-cyclodextrin (THC/beta-CD) complex, and was compared to oral administration of ethanolic THC, in rabbits. The absolute bioavailability of THC after sublingual administration of solid THC/beta-CD complex powder (16.0 +/- 7.5%; mean +/- SD; n = 4) is higher than the bioavailability of THC after oral administration of ethanolic THC solution (1.3 +/- 1.4%; mean +/- SD; n = 4). The results suggest that sublingual administration of THC/beta-CD complex is a useful tool in improving absolute bioavailability of THC.
