Dose-response effects on alcohol intake in both males (n = 9) and females (n = 10) for R(+)-Baclofen (A), S(−)-Baclofen (B) and RS-Baclofen (C). All doses of the different forms of Baclofen were administered in a random order. Rats received first the R(+)-Baclofen, then the S(−)-Baclofen and finally the RS-Baclofen. A significant dose and sex effect was found only for the R(+)-Baclofen. Data have been normalized so that the 100% represents the level of ethanol self-administration during the last session of the 5 consecutive sessions (days) of habituation (saline but no baclofen injection).
