Relationship between dopamine D2 receptor occupancy, clinical response, and drug and monoamine metabolites levels in plasma and cerebrospinal fluid. …
2009
Combining measurements of the monoamine metabolites in the cerebrospinal fluid (CSF) and neuroimaging can increase efficiency of drug discovery for treatment of brain disorders. To address this question, we examined five drug-naive patients suffering from schizophrenic disorder. Patients were assessed clinically, using the Positive and Negative Syndrome Scale (PANSS): at baseline and then at weekly intervals. Plasma and CSF levels of quetiapine and norquetiapine as well CSF 3,4-dihydroxyphenylacetic acid (DOPAC), homovanillic acid (HVA), 5-hydroxyindole-acetic acid (5-HIAA) and 3-methoxy-4-hydroxyphenylglycol (MHPG) were obtained at baseline and again after at least a 4 week medication trai…
Tools for optimising pharmacotherapy in psychiatry (therapeutic drug monitoring, molecular brain imaging and pharmacogenetic tests): focus on antidep…
2021
Contains fulltext : 238693.pdf (Publisher’s version ) (Open Access) Objectives: More than 40 drugs are available to treat affective disorders. Individual selection of the optimal drug and dose is required to attain the highest possible efficacy and acceptable tolerability for every patient.Methods: This review, which includes more than 500 articles selected by 30 experts, combines relevant knowledge on studies investigating the pharmacokinetics, pharmacodynamics and pharmacogenetics of 33 antidepressant drugs and of 4 drugs approved for augmentation in cases of insufficient response to antidepressant monotherapy. Such studies typically measure drug concentrations in blood (i.e. therapeutic …

Consensus Guidelines for Therapeutic Drug Monitoring in Neuropsychopharmacology: Update 2017
2017
AbstractTherapeutic drug monitoring (TDM) is the quantification and interpretation of drug concentrations in blood to optimize pharmacotherapy. It considers the interindividual variability of pharmacokinetics and thus enables personalized pharmacotherapy. In psychiatry and neurology, patient populations that may particularly benefit from TDM are children and adolescents, pregnant women, elderly patients, individuals with intellectual disabilities, patients with substance abuse disorders, forensic psychiatric patients or patients with known or suspected pharmacokinetic abnormalities. Non-response at therapeutic doses, uncertain drug adherence, suboptimal tolerability, or pharmacokinetic drug…
Problem solving in psychopharmacotherapy using pharmacokinetic and pharmacogenetic tests
2007
Many problems such as non-response, pharmacokinetic interactions with clinical consequences and adverse effects (pharmacovigilance) may be observed in patients submitted to psychopharmacotherapy. These risks are increased in patients belonging to the category of “special populations”: elderly patients, children and adolescents, patients with a genetic particularity of metabolism or suffering from somatic or psychic comorbidities. Pharmacokinetic and pharmacogenetic tests are useful to solve problems in psychopharmacotherapy and thus improve efficacy and safety. Therapeutic drug monitoring (TDM) is particularly recommended in situations presented above and in patients who are non-compliant. …
Therapeutic drug monitoring of drugs for treatment of substance-related disorders
2011
IntroductionThe effect of pharmacotherapy of substance-related disorders is moderate at best.ObjectivesTherapeutic drug monitoring (TDM) could be an instrument to improve the outcomes. TDM is for most of these drugs not established yet.AimsThe authors built a literature based rating scale to evaluate the necessity of TDM for these pharmacological agents.MethodsA literature research was performed for TDM related properties of acamprosate, bupropion, buprenorphine, clomethiazole, disulfiram, methadone, naltrexone, and varenicline. A rating scale was established for evaluation. It included 28 items related to five categories (efficacy, toxicity, pharmacokinetics, patient characteristics and co…
Pharmakokinetik, Pharmakogenetik und therapeutisches Drug Monitoring
2008
Um einen pharmakologischen Effekt zu erzeugen, muss ein Medikament den Wirkort in ausreichender Konzentration erreichen. Welche Menge den Wirkort erreicht, hangt wesentlich von der Dosis ab, aber auch von vielen weiteren Faktoren, die bestimmen, welche Mengen resorbiert werden und wie das Medikament im Korper verteilt, abgebaut und ausgeschieden wird. Diese Prozesse sind auch dafur verantwortlich, wie lange die Wirkung anhalt. Die Pharmakokinetik beschreibt und erklart diese Zusammenhange, insbesondere den zeitlichen Konzentrationsverlauf der Medikamente und ihrer Metaboliten in Flussigkeiten und Geweben des Korpers. Sie versucht auch, zu erklaren, welche biologischen Mechanismen fur diese …
SPCCTDM, a Catalogue for Analysis of Therapeutic Drug Monitoring Related Contents
2013
Therapeutic drug monitoring (TDM) has consistently been shown to be useful for optimization of drug therapy. For the first time, a method has been developed for the text analysis of TDM in SPCs in that a catalogue SPC-ContentTDM (SPCCTDM) provides a codification of the content of TDM in SPCs. It consists of six structure-related items (dose, adverse drug reactions, drug interactions, overdose, pregnancy/breast feeding, and pharmacokinetics) according to implicit or explicit references to TDM in paragraphs of the SPC, and four theory-guided items according to the information about ranges of plasma concentrations and a recommendation of TDM in the SPC. The catalogue is regarded as valid for t…
Therapeutic Drug Monitoring for Drugs Used in the Treatment of Substance-Related Disorders: Literature Review Using a Therapeutic Drug Monitoring App…
2011
Background The efficacy of drugs for the treatment of substance-related disorders is moderate at best. Therapeutic drug monitoring (TDM) could be an instrument to improve outcomes. Because TDM for most of those drugs is not established, the authors reviewed the literature and built a rating scale to detect the potential added value of TDM for these pharmacologic agents. Methods A literature search was performed for acamprosate, bupropion, buprenorphine, clomethiazole, disulfiram, methadone, naltrexone, and varenicline. The rating scale included 22 items and was divided in five categories: efficacy, toxicity, pharmacokinetics, patient characteristics, and cost-effectiveness. Three reference …

O-18 - TDM in patients with substance related disorders
2012
The effect of pharmacotherapy of substance-related disorders is moderate at best. Therapeutic drug monitoring (TDM) could be an instrument to improve the outcomes. Since TDM for these drugs is not well established, the authors built a literature based rating scale to evaluate the necessity of TDM for the use of these pharmacological agents. Methods A literature research was performed for acamprosate, bupropion, buprenorphine, clomethiazole, disulfiram, methadone, naltrexone, and varenicline. A rating scale including 22 items, divided in five categories (efficacy, toxicity, pharmacokinetics, patient characteristics and cost effectiveness) was established for evaluation and related to the amo…
French summaries of product characteristics: content in relation to therapeutic monitoring of psychotropic drugs
2010
The prescription information (summary of product characteristics, SPC) is compiled by the pharmaceutical industry as required by the national regulatory authorities. They vary in their content about the properties of drugs and about the usefulness of therapeutic drug monitoring (TDM) in the blood of patients. Based on a previous study carried out in Germany, the degree of agreement of French SPC for 59 psychotropic drugs with the existing medico-scientific evidence in the area of TDM was examined using a recently developed instrument. A summary score of SPC content (SPCC) related to TDM (SPCC TDM ) has been calculated and compared with the level of recommendation of TDM of the AGNP-TDM expe…
