Randomized Controlled TrialEthanol and pain sensitivity: effects in healthy subjects using an acute pain paradigm.
The primary objective of this study was to determine whether healthy subjects without a history of heavy alcohol use or a family history of alcoholism exhibit a concentration-dependent analgesic effect of ethanol. In a preliminary fashion, we also compared this sample to a group of subjects with a strong positive family history for alcoholism (FHP) to test the secondary hypothesis that FHP individuals will be more sensitive to the analgesic effects of alcohol compared to healthy subjects who are negative for a family history of alcoholism (FHN). ⋯ The findings support the hypothesis that in healthy subjects intravenous ethanol administration has a concentration effect on pain tolerance but not on pain threshold. Additional studies are planned to further elucidate the mechanisms of ethanol's analgesic effects.
