Zuclopenthixol is indicated the management of the manifestations of schizophrenia and other mental illnesses with disturbances in thinking, emotional reactions and behaviour. It is also used to treat the manic phase of manic depressive illness. Zuclopenthixol, a thioxanthene derivative, has high affinity for both dopamine D1 receptors and dopamine D2 receptors. Zuclopenthixol also has high affinity for α1-adrenergic and 5-HT2 receptors. Zuclopenthixol (CLOPIXOL®) is avavilable in the form of tablets and solution for intramuscular injections.

Bromperidol decanoate is a long-acting antipsychotic medication used in at least Belgium, Germany, Italy, and the Netherlands. In clinical trials, Bromperidol decanoate was effective in the treatment of residual schizophrenia, with significant differences between before and after treatment ratings for symptoms. The preparation seems to be less potent than other depot antipsychotics (such as fluphenazine and haloperidol decanoate) and better than placebo injection. If bromperidol decanoate is available to the clinician it may be a viable choice, especially when there are reasons not to use fluphenazine or haloperidol decanoate.
