Abstract
The decrease in the Bmax value of 3H-dihydroalprenolol (3H-DHA) binding to cortical membranes of rat brain induced by long-term administration of desipramine (DMI) was prevented by concomitant treatment with parachlorophenylalanine (pCPA). Acute administration of DMI significantly decreased locomotor activity in saline- and (pCPA)-pretreated rats. DMI-induced inhibition of locomotor activity was abolished in (pCPA)-pretreated rats chronically treated with DMI. Conversely, in pCPA-pretreated animals, acute DMI could still significantly decrease the locomotion of chronically DMI-treated rats. The data presented indicated that an intact serotoninergic system is required to enable antidepressant drugs to induce biochemical and behavioral changes following their chronic administration. © 1985 Springer-Verlag.
