title: Effects of combined administration of imipramine and chlorpromazine on beta- and alpha 2-adrenergic receptors in rat cerebral cortex.
abstract: Administration of the combination of antidepressant and neuroleptic drugs has been reported to have a synergistic effect in the treatment of delusional depression. The effects of chronic coadministration of imipramine (IMIP) and chlorpromazine (CPZ) on beta-adrenergic and alpha 2-adrenergic binding sites in rat cerebral cortex were studied. The combination caused the same reduction in the number of beta-adrenergic receptors as IMIP alone. No changes in alpha 2-adrenergic receptors were observed with IMIP and/or CPZ.
