Relationship between mirtazapine dose, plasma concentration, response, and side effects in clinical practice.

Objective: The aim of this study was to evaluate the benefit of mirtazapine plasma concentration monitoring in a typical clinical setting.

Methods: The relationship between mirtazapine plasma concentration, dose, response, and side effects was studied in 65 inpatients presenting with a depressive episode according to ICD-10. Plasma concentrations, the 17-item Hamilton Depression Rating (HAMD), and the UKU side effect rating were performed weekly.

Pharmacokinetics of m-chlorophenylpiperazine after intravenous and oral administration in healthy male volunteers: implication for the pharmacodynamic profile.

Introduction: Serotonin plays an important role in psychiatric diseases, most notably in depression and anxiety. Seven different major serotonin receptor subtypes have been described. Receptor-selective agonists and antagonists have been searched for to find a suitable drug to test the in vivo receptor sensitivity.

Analysis of eighteen antidepressants, four atypical antipsychotics and active metabolites in serum by liquid chromatography: a simple tool for therapeutic drug monitoring.

Therapeutic drug monitoring necessitates efficient, fast and reliable analytical methods validated by external quality control. We therefore devised an isocratic reversed-phase HPLC method with ultraviolet detection and optimised this to quantify mirtazapine, reboxetine, moclobemide, venlafaxine, O-desmethylvenlafaxine, paroxetine, fluvoxamine, fluoxetine, norfluoxetine, sertraline, citalopram, amitriptyline, nortriptyline, imipramine, desipramine, doxepin, nordoxepin, clomipramine, norclomipramine, trimipramine, mianserine, maprotiline, normaprotiline, amisulpride, clozapine, norclozapine, quetiapine, risperidone and 9-OH-risperidone in human serum. After solid-phase extraction of the drugs and metabolites, the chromatographic separation was achieved on a Nucleosil 100-Protect 1 column with acetonitrile-potassium dihydrogenphosphate buffer as mobile phase.
