Mayerová M, Turjap M, Ustohal L, Pivnička J, Češková E. Therapeutic drug monitoring of olanzapine and clozapine The article summarizes existing basic literature and recommendations concerning therapeutic drug monitoring (TDM) of antipsychotics. It is focused on olanzapine and clozapine. Moreover, the terms "therapeutic drug monitoring" and "therapeutic reference range" are explained and indications for TDM are summarized. The factors that can influence plasma levels and that can be influenced by plasma levels are also mentioned. The article reports, where and how TDM can be done in the Czech Republic.

Background. Psychiatric disorders contribute significantly to worldwide morbidity and mortality. In the case of depression and schizophrenia, effective drug therapy is available but 30-50% of patients do not respond sufficiently to the initial treatment regimen. Apart from the development of new molecules, it is desirable to optimize treatment outcomes with agents that are currently available. Therapeutic drug monitoring (TDM) is a suitable and widely accepted approach for improving the efficacy and safety of these drugs. Methods. A review of the relevant literature published between 2006 and January 2015. Results and Conclusions. This review describes major advances and drawbacks in the field of chromatography coupled with single or tandem mass spectrometry (LC-MS, LC-MS/MS and GC/MS) of selected antidepressants (agomelatine, vilazodone) and antipsychotics (iloperidone, asenapine, amisulpride, aripiprazole, melperone, zotepine, ziprasidone). The high specificity in combination with high sensitivity makes these techniques an attractive complementary method to traditional procedures used in routine practice for TDM. [ABSTRACT FROM AUTHOR]

Quetiapine is atypical antipsychotic with remarkable clinical and receptor-binding profile depending on dosage used. Plasma concentrations and also clinical response vary markedly after equal doses between individuals in clinical practice. Polypharmacy and suboptimal adherence is common. The drug is metabolised by cytochrome P450 and thus, clinically important pharmacokinetic drug-drug interactions are likely. There is evidence from literature about plasma concentrations obtained at therapeutically effective doses. Quetiapine is therefore suitable candidate for therapeutic drug monitoring. Here we present an overview of biotransformation and pharmacokinetic drug-drug interactions and current knowledge on therapeutic drug monitoring of quetiapine, its benefits and limitations.
