Abstract
Regional distribution of imipramine, desipramine and specific [3H]desipramine binding sites in the rat brain after acute and chronic treatment of rats with imipramine has been investigated. Both substances were distributed unevenly within rat brain after single and prolonged administration of imipramine. This was partly connected with the regional cerebral blood flow, lipid content in the regions and lipophilicity of the substances investigated. It was also found that the number of specific [3H]desipramine binding sites was different in the various brain areas, and that prolonged administration of imipramine led to a decrease of their number in some of those regions. No correlation was found between the regional cerebral distribution of desipramine and the regional density of specific [3H]desipramine binding sites.Keywords
