  • Title: [Effect of antidepressants on the balance of biogenic amines and their metabolites in the rat brain].
    Author: Kamysheva VA, Gankina EM, Markin VA.
    Journal: Farmakol Toksikol; 1985; 48(5):22-4. PubMed ID: 2416591.
    Abstract:
    A study was made of changes in the balance of neuromediator monoamines and metabolistes in rat brain, induced by a single administration of pyrazidol, imipramine and norzimelidine. It was revealed that pyrazidal in a dose of 50 mg/kg increased the level of noradrenaline (NA) and serotonin (5-HT), particularly in the hypothalamus and raphe-nucleus of rat brain. In the same brain regions, imipramine (30 mg/kg) raised the NA content and lowered the concentration of 5-HT and dopamine (DA) metabolites. Norzimelidine (60 mg/kg) elevated the levels of NA and DA in the hypothalamus and reduced the 5-HT content in the raphe nucleus of rat brain. It is suggested that the topography of changes in the balance of biogenic amines in the brain induced by different antidepressants reflects the pharmacological features of their action.
