title: The effect of naltrexone on taste detection and recognition threshold.
abstract: Eighteen healthy female volunteers were administered 50 mg naltrexone in a double-blind, placebo control study. Relative taste detection and recognition thresholds for sweet, salty, sour and bitter taste and liking for and perception of sucrose solutions were determined at baseline and 1 hour after administration of naltrexone. Naltrexone did not alter relative taste detection and recognition thresholds for any of the four tastes or perception of sweetness. However, a significant, but slight, decrease in liking for sucrose solutions occurred after naltrexone administration. These findings suggest that opioid-dependent intake is independent of changes in taste perception in humans.
