How it works
Clozapine has been shown to be an antipsychotic agent that is different from classic antipsychotics. In pharmacological experiments, the compound does not induce catalepsy or inhibit apomorphine- or amphetamine-induced stereotyped behaviour. It has only weak dopamine-receptor-blocking activity at D1, D2, D3 and D5 receptors, but shows high potency for the D4 receptor. Clozaril has potent anti-alpha-adrenergic, anticholinergic, antihistaminic, and arousal-reaction-inhibiting effects. It has also been shown to possess antiserotoninergic properties.

When not to Use
Do not take if you : Are allergic (hypersensitive) to clozapine or any of the other ingredients ; Are not able to have regular blood tests ; Have ever been told you have a low white blood cell count (e.g. leucopenia or agranulocytosis), especially if this was caused by medicines. This does not apply if you have had low white blood cell count caused by previous chemotherapy ; had to stop using this medicine previously because of severe side effects (e.g. agranulocytosis or heart problems).
Precaution
Prior to treatment initiation, physicians must ensure, to the best of their knowledge, that the patient has not previously experienced an adverse haematological reaction to clozapine that necessitated its discontinuation. Prescriptions should not be issued for periods longer than the interval between two blood counts .
Warning 1
Clozapine can cause agranulocytosis. The incidence of agranulocytosis and the fatality rate in those developing agranulocytosis have decreased markedly since the institution of white blood cell (WBC) counts and absolute neutrophil count (ANC) monitoring. The following precautionary measures are therefore mandatory and should be carried out in accordance with official recommendations.
Warning 2
Patients with a history of primary bone marrow disorders may be treated only if the benefit outweighs the risk. They should be carefully reviewed by a haematologist prior to starting Clozapine.
Warning 3
Patients who have low WBC counts because of benign ethnic neutropenia should be given special consideration and may only be started on Clozapine with the agreement of a haematologist.
