Clozapine + Norclozapine details
What Clozapine + Norclozapine shows
This test measures blood levels of clozapine together with norclozapine, its main active breakdown product (metabolite), giving a fuller picture of clozapine exposure than measuring clozapine alone. The ratio between the two can offer additional information about how a person is metabolizing the medication, which can be affected by liver function, smoking status, and other medications. As with clozapine alone, this combined test is used to help guide safe, effective dosing of this antipsychotic medication, which requires careful monitoring due to its narrow therapeutic range and risk of significant side effects.
Tests that include Clozapine + Norclozapine
Clozapine is an antipsychotic medication used primarily to treat schizophrenia in patients who have not responded to other treatments. A Clozapine blood level test measures the amount of the drug in the blood to ensure it is within a therapeutic range and to avoid toxicity. Monitoring is crucial because clozapine can cause serious side effects, including agranulocytosis (a dangerous drop in white blood cells), requiring regular blood count checks.
