pH-dependent interaction of psychotropic drug with glycerophospholipid monolayers studied by the Langmuir technique.

We have earlier investigated the interaction of the antipsychotic drugs chlorpromazine(CPZ) and olanzapine(OLP) with glycerophospholipid monolayers. These experiments were carried out at high and low temperatures and showed that OLP had a more pronounced effect on the packing of the phospholipid (PL) monolayers than CPZ. At pH 7.
