CP-94253 is a drug which acts as a potent and selective serotonin5-HT1Breceptoragonist, with approximately 25× and 40× selectivity over the closely related 5-HT1D and 5-HT1A receptors.[1] It has a range of behavioral effects, based on animal testing. The effects include the following: promoting wakefulness by increasing dopamine release in the brain;[2][3] reducing food intake and promoting satiety;[4][5][6] enhancing the reinforcing effects of cocaine;[7][8][9][10] and possible antidepressant effects.[11] A recent study[12] found that "Regardless of sex, CP94253 decreased cocaine intake after abstinence and during resumption of SA [self-administration] and decreased cue reactivity" suggesting that agonism of the inhibitory 5-HT2B receptors may diminish the cognitive reward of cocaine usage and increased use of the drug without a period of abstinence may be a product of test subjects trying to achieve a previously rewarding experience through larger dosages of cocaine.
