[Interaction of psychotropic preparations with model lipid membranes]

Interaction of psychotropic drugs with model phosphatidylcholine membranes was investigated by fluorescent probes. The data obtained indicate different affinity of the drugs for phosphatidylcholine. The tranquilizers were not bound to the model membranes. The antidepressants were localized in the lipid polar groups area whereas the neuroleptics in the lipid polar groups area and deeper regions of the lipid bilayer.
