Loxapine (sold as Loxapac, Loxitane) is a typical antipsychotic medication, used primarily in the treatment of schizophrenia. It is a member of the dibenzoxazepine class and as a dibenzazepine derivative, it is structurally related to clozapine (which belongs to the chemically closely akin class of dibenzodiazepines). Several researchers have argued that Loxapine may behave as an atypical antipsychotic [1].
Loxapine may be metabolized by N-demethylation to amoxapine, a tricyclic antidepressant [2].

[edit] Side effects
- Further information: Typical antipsychotic
The most significant side-effects of loxapine are excessive salivation and indifference to surroundings. Loxapine, if administered to individuals without schizophrenia, causes emotional quieting and insensitivity. In persons with psychosis, it may control aggressive behaviour and restlessness, and reduce the severity of hallucinations and delusions. Other Side effects include tardive dyskinesia, neuroleptic malignant syndrome, extrapyramidal side effects, tremor, gynecomastia and sedation.
[edit] Dosage
The typical starting dosage is 10mg twice daily; usual dose range 30-50mg twice daily; maximum recommended dosage is 250mg per day.
