Ethanol consummatory patterns of individual male and female rats and the effects of Hoe-427 (Ebiratide), and ACTH{sub 4-9} analog, thereon, were studied in a test system using 24 hour, two-bottle free choice consumption between 0.2% saccharin and 10% ethanol in 0.2% saccharin. Single, daily i.p. doses of either ACTH{sub 4-10} or its analog resulted in a significant reduction of daily ethanol consumption with no effects on saccharin consumption. After 4 days of treatment, male rats consistently exhibited a rebound increase in ethanol consumption; this effect was not seen in females. The daily ethanol consummatory patterns of the female animals seemed to exhibit a 4-6 day cyclic rhythymicity, suggesting an interaction with estrous cycles. These results support a role for ACTH{sub 4-10} in the initiation of ethanol consummatory behavior in rats and suggests the existence of sex differences in this phenomenon.
