“…Despite TDM's potential, considerable disagreement was found between the information on TDM in official product information and existing medico-scientific evidence. Even for well-studied compounds, such as amitriptyline or clozapine, insufficient information on TDM was found in the product information (Summary of Product Characteristics, SPC) [1020,1221]. For a large number of neuropsychopharmacological drugs, however, the quantification of blood concentrations has become clinical routine.…”

Therapeutic 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-drug interactions are typical indications for TDM. However, the potential benefits of TDM to optimize pharmacotherapy can only be obtained if the method is adequately integrated in the clinical treatment process. To supply treating physicians and laboratories with valid information on TDM, the TDM task force of the Arbeitsgemeinschaft für Neuropsychopharmakologie und Pharmakopsychiatrie (AGNP) issued their first guidelines for TDM in psychiatry in 2004. After an update in 2011, it was time for the next update. Following the new guidelines holds the potential to improve neuropsychopharmacotherapy, accelerate the recovery of many patients, and reduce health care costs.

“…The information content of SmPCs has been subject to considerable research over the past years [16,19,25,26]. Completeness of information is an essential prerequisite of any medicines information source and this has been pointed out as an issue in SmPCs [16].…”

“…Despite being considered a leading source of information for safety data and evidence-based prescribing decisions [15], SmPCs have been criticized for containing important clinical pharmacology information deficits [16], for being suboptimal sources of information for drug−drug interactions [17], food−drug interactions [18], therapeutic drug monitoring [19], or dose adjustment in renal impairment [20]. In addition, SmPCs have also been criticized for being too verbose, lacking standardization and being heterogeneous [21].…”

AIMSTo assess the completeness and applicability of information for the use of medicines in pregnancy and lactation contained in European Summaries of Product Characteristics (SmPCs). METHODSSmPCs available on the EMA website in April 2011 were retrieved, and information on the use of medicines during pregnancy and lactation was analyzed. A form was designed to extract information regarding drug concentrations crossing the placenta, excretion of the drug in milk, the existence of pre-clinical and clinical studies and clinical experience describing the use of the medicine in pregnancy and lactation, medicine effects on human fertility, medicines use in women of child-bearing potential and specific recommendations for use during pregnancy and breastfeeding. SmPCs were classified as containing 'conclusive' or 'ambiguous' information depending on whether (or not) they provided clear instructions regarding medicine use in pregnancy and lactation. RESULTSOf the 534 SmPCs, 89.3% did not mention whether the drug crossed the placenta, 67.6% indicated that there was no clinical experience during pregnancy and in 61.4% it was unknown whether the medicine was excreted in human milk. Recommendations for medicine use during pregnancy and breastfeeding were ambiguous in 57.0% and 16.5% of the SmPCs, respectively, and medicine use was restricted in over 90% SmPCs for both pregnancy and breastfeeding, despite no information supporting these restrictions being reported. The time elapsed since a SmPCs first approval was not associated with an increase in information quality. CONCLUSIONSImportant information deficits on the use of medicines during pregnancy and breastfeeding were found in European SmPCs. WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT• Reliable information regarding the use of many medicines during pregnancy is critical for researchers and healthcare professionals who work in antenatal care, but this information has been found to differ across different sources.• The Summary of Product Characteristics (SmPCs) is the European official medicines information source for professionals and contains a specific section to include information on medicines use during pregnancy and lactation to guide decision making.• Future electronic versions of SmPCs to be included in clinical decision support systems will require intelligible and logical electronic information. WHAT THIS STUDY ADDS• Important information deficits on the use of medicines during pregnancy and lactation were found in European SmPCs, and the time elapsed since a SmPC's marketing authorization was not associated with an increase in information quality.• Post-authorization data on the exposure to medicinal products during pregnancy and lactation should be actively collected and included in official information sources to keep them updated and to assist decision making.

“…Product information should be supplemented with TDM related data to enhance the therapeutic eff ectiveness of psychoactive drugs. Analyses of German [ 671 ] and French [ 568 ] summaries of product characteristics (SPC) revealed that many SPC do not contain TDM related information in spite of available valid clinical-scientifi c evidence. Another need for research is to study cost-eff ectiveness of TDM when the method is used in an appropriate way.…”

than 5 decades [ 521 , 522 ] , growing evidence suggests that improving the way the available medications are administered may bring substantial benefi t to patients [ 45 ] . Evidence-based guidelines for optimum treatment have been published during the last decade [ 23 , 46 , 101 , 204 , 205 , 221 , 234 , 254 , 276 , 284 , 582 , 585 ,748]. A valuable tool for tailoring the dosage of the prescribed medication(s) to the individual characteristics of a patient is therapeutic drug monitoring (TDM). The major reason to use TDM for the guidance of psychopharmacotherapy is the Introduction ▼ In psychiatry, around 130 drugs are now available which have been detected and developed during the last 60 years [ 54 ] . These drugs are eff ective and essential for the treatment of many psychiatric disorders and symptoms. Despite enormous medical and economic benefi ts, however, therapeutic outcomes are still far from satis factory for many patients [ 5 , 6 , 396 , 661 ] . Therefore, after having focused clinical research on the development of new drugs during more Therefore the TDM consensus guidelines were updated and extended to 128 neuropsychiatric drugs. 4 levels of recommendation for using TDM were defi ned ranging from "strongly recommended" to "potentially useful". Evidence-based "therapeutic reference ranges" and "dose related reference ranges" were elaborated after an extensive literature search and a structured internal review process. A "laboratory alert level" was introduced, i. e., a plasma level at or above which the laboratory should immediately inform the treating physician. Supportive information such as cytochrome P450 substrateand inhibitor properties of medications, normal ranges of ratios of concentrations of drug metabolite to parent drug and recommendations for the interpretative services are given. Recommendations when to combine TDM with pharmacogenetic tests are also provided. Following the guidelines will help to improve the outcomes of psychopharmacotherapy of many patients especially in case of pharmacokinetic problems. Thereby, one should never forget that TDM is an interdisciplinary task that sometimes requires the respectful discussion of apparently discrepant data so that, ultimately, the patient can profi t from such a joint eff ort.

At the very same dose, a more than 20-fold interindividual variation in the medication's steady state concentration in the body may result, as patients diff er in their ability to absorb, distribute, metabolize and excrete drugs due to concurrent disease, age, concomitant medication or genetic peculiarities [ 61 , 94 , 310 , 311 , 334 , 335 , 374 ] . Diff erent formulations of the same medication may also infl uence the degree and temporal pattern of absorption and, hence, medication concentrations in the body. TDM uses the quantification of drug concent...
