Trial 2, 5-day treatment: Effects of doxazosin (2.5 – 10 mg/kg, IP) on alcohol intake (mean ±S.E.M). Each bar represents data from 11 - 12 rats. “A” and “B” indicate behavioral tests discussed in the Results section. *p < .05, **p < .001, ***p < .001 versus vehicle control treatment within individual days. For significant differences between doxazosin doses and between days, see text. Pre-treatment values reflect the averages from 5 daily sessions.
