The present communication reports on the efficacy of (R)-8-OH-DPAT ((R)-8-hydroxy-2-(di-n-propylamino)tetralin) and (S)-LY-41 ((S)-8-acetyl-2-(di-n-propylamino)tetralin) in displaying the 5-HT1A syndrome and decreasing body temperature after administration of the compound subcutaneously into the gastric ventricle or into the oral cavity in the rat. The dose range eliciting a clear-cut HT1A syndrome and hypothermia after oral cavity administration was 1/10-1/30 that of the gastric ventricle dose range, but 10-30 times higher than the dose range used for subcutaneous administration of both (R)-8-OH-DPAT and (S)-LY-41. Determination of the concentrations of (R)-8-OH-DPAT in plasma and brain tissue confirmed a higher bioavailability after oral cavity than after gastric ventricle administration; plasma and brain tissue concentrations of the drug were found to be approximately 3 times those after 10 mumol/kg-1 orally than after 100 mumol/kg-1 gastroventrically at 15-60 min after administration of (R)-8-OH-DPAT. These findings suggest that the oral cavity may be an important site for drug delivery of 8-OH-DPAT, LY-41 and other compounds with a low gastrointestinal bioavailability.
