Psychopharmaca are a large group of drugs widely used not only in psychiatry. Their systemic administration affects both the main diagnosis and the organism as a whole. The subject of our experiments is the effect of psychopharmaca on the changes in mitochondrial functions, which is beneficial for understanding of molecular mechanisms of therapeutic and adverse effects of drugs. The aim of this thesis was to study the in vitro effects of selected drugs on the cell energy metabolism. Selected antipsychotics (chlorpromazine, levomepromazine, haloperidol, risperidone, ziprasidone, zotepine, aripiprazole, clozapine, olanzapine, and quetiapine), antidepressants (bupropion, fluoxetine, amitriptyline, imipramine) and mood stabilizers (lithium, valproate, valpromide, lamotrigine, carbamazepine) were tested. In vitro effects of selected psychopharmaca were measured on isolated pig brain mitochondria. The activities of citrate synthase (CS) and electron transport chain (ETC) complexes (I, II+III, IV) were measured spectrophotometrically. Drug-induced changes of mitochondrial respiration rates linked to complex I (supported by malate and pyruvate) and complex II (supported by succinate) were evaluated by high resolution respirometry. Complex I was significantly inhibited by lithium, carbamazepine, fluoxetine,...
