Molindone hydrochloride, a dihydroindolone neuroleptic, is structurally distinct from other classes of neuroleptics. Molindone exhibits many similarities to other neuroleptics, including dopamine receptor blockade, antipsychotic efficacy, and extrapyramidal side effects. Despite these similarities, molindone also has atypical properties and inhibits the enzyme monoamine oxidase in vitro and in vivo. Several studies have shown that molindone causes less dopamine receptor supersensitivity than other neuroleptics and thus may be less likely to cause tardive dyskinesia. It also appears to have a greater effect on mesolimbic and mesocortical dopamine neurons than on those in the nigrostriatal dopamine system. Clinically, molindone has a tendency to cause weight loss and may have less effect on seizure threshold than conventional antipsychotic agents. The authors review the laboratory and clinical data on molindone and discuss the relevance of atypical research findings to the clinical characteristics of this antipsychotic agent.

To estimate the relative risk of various neuroleptic medications for patients with epilepsy or likely to have neuroleptic-induced seizures, their action on spike activity in perfused guinea pig hippocampal slices was studied. Within the range of concentrations studied, molindone hydrochloride, butaclamol hydrochloride, pimozide, and fluphenazine dihydrochloride produced the least increase in excitability. There were also differences in the dose-response curves. Chlorpromazine, thioridazine, and pimozide produced an inverted U-shaped curve. For haloperidol and fluphenazine, excitability tended to increase and them plateau. Molindone and butaclamol produced no increase in excitability. Combinations of neuroleptics had synergistic effects, while the anticonvulsant diazepam inhibited neuroleptic-induced excitability. This article discusses the clinical implications of these findings and their effect on theories of which neuroleptics might produce the fewest seizures.
