Drug Name Olanzapine
Drug ID BADD_D01599
Description Olanzapine is a thienobenzodiazepine classified as an atypical or second-generation antipsychotic agent.[A176996] The second-generation antipsychotics were introduced in the 90s and quickly gained traction due to their impressive efficacy, reduced risk for extrapyramidal side effects and reduced susceptibility to drug-drug interactions.[A177011] Olanzapine very closely resembles [clozapine] and only differs by two additional methyl groups and the absence of a chloride moiety.[T554] It was discovered by scientists at Eli Lilly and approved to be marketed in the US in 1996.[T548]
Indications and Usage Olanzapine was initially used orally and intramuscularly for the chronic treatment of schizophrenia in patients over 13 years old and other psychiatric disorders such as bipolar I disorder including mixed or manic episodes.[A177014] Olanzapine is also indicated, in combination with lithium or valproate for the short-term treatment of acute manic or mixed episodes associated with bipolar I disorder in adults.[FDA label] As well, olanzapine is indicated, in combination with fluoxetine for the treatment of episodes of depression associated with bipolar disorder type 1 and treatment-resistant depression in patients over 10 years old.[A177014] Olanzapine is also approved for the management of psychomotor agitation associated with schizophrenia and bipolar I mania.[FDA label] Schizophrenia is a complex biochemical brain disorder that affects the person's ability to differentiate reality. It is usually observed as the presence of delusions, hallucinations, social withdrawal and disturbed thinking.[L5936] Bipolar disorder is a mental health condition defined by periods of extreme mood disturbances. It is categorized in different types from which type 1 is known to involve episodes of severe mania and often depression while type 2 presents less severe forms of mania.[L5939] Olanzapine is also indicated in combination with [samidorphan] for the treatment of bipolar I disorder, either as an adjunct to lithium or valproate or as monotherapy for the acute treatment of manic or mixed episodes or as maintenance therapy, and for the treatment of schizophrenia in adults.[L34359]
