Comparison of Mw\Pharm 3.30 and Mw\Pharm ++ (Windows version) software for PK/PD monitoring of vancomycin: A priori modeling.

Objective: To evaluate the possibility of population-based dose optimization with the aid of MwPharm modeling and to find the best model in the Windows version (WIN).

Materials: 25 patients repeatedly examined for vancomycin (mean age 63 ± 14 years, body weight 88 ± 21 kg, median dose 1 g/12 h).

Methods: Trough concentrations predicted by WIN models , , , and DOS model (DOS) were compared with the measured value.

Comparison of Mw\Pharm 3.30 and Mw\Pharm ++, a Windows version of pharmacokinetic software for PK/PD monitoring of vancomycin. Part 1: A-posteriori modelling.

Background And Objectives: For a long time, the Mw\Pharm software suite (MEDI\WARE, Prague, Czech Republic/ Groningen, Netherlands) has been used for PK/PD modelling in therapeutic drug monitoring (TDM). The aim of this study was to find the best model in the newer Windows Mw\Pharm++ 1.3.

Was it necessary to change the therapeutic range of topiramate?

Aims: The Norwegian Association for Clinical Pharmacology in their National Guidelines decreased the therapeutic range (TR) of topiramate (TPM) from 5-20 mg/L to 2-10 mg/L. The objective of this study is to ascertain which TR produces better clinical outcomes.

Methods: The data sources were request forms for routine therapeutic drug monitoring (TDM) of TPM.

Monitoring topiramate concentrations at delivery and during lactation.

Objective: To determine transplacental passage of topiramate and its transport to colostrum, mature maternal milk and breastfed infants, we examined data from 27 women treated with topiramate from 2004 to 2020.

Methods: In this cohort study, maternal serum, umbilical cord serum, milk and infant serum levels were measured by gas chromatography in the delivery subgroup, the colostrum subgroup (3-4 days postpartum) and the mature milk subgroup (7-30 days postpartum). Paired umbilical cord serum, maternal serum, breastfed infant serum, and milk levels were used to assess the ratios of umbilical cord/maternal serum, milk/maternal serum and infant/maternal serum levels.

Lamotrigine drug interactions in combination therapy and the influence of therapeutic drug monitoring on clinical outcomes in paediatric patients.

The aim was to study the impact of therapeutic drug monitoring (TDM) on paediatric patients on lamotrigine therapy and the evaluation of possible drug interactions, especially in triple antiepileptic drug combinations. During the period of 2001-2015, 1308 pre-dose samples were taken from 430 patients <15 years of age as part of routine TDM. Drug interactions were evaluated using calculation of lamotrigine clearance.

Lamotrigine Drug Interactions in Combination Therapy and the Influence of Therapeutic Drug Monitoring on Clinical Outcomes of Adult Patients.

Background: The aim was to study the impact of therapeutic drug monitoring (TDM) on patients on lamotrigine (LTG) therapy and the evaluation of possible drug interactions, especially in triple antiepileptic drug combinations.

Methods: During the period of 2001-2014, 3118 predose samples were taken from 1137 patients >15 years of age as part of their routine TDM. Drug interactions were evaluated using calculation of LTG clearance (CL).

Validation of sparse sampling strategies to estimate cyclosporine A area under the concentration-time curve using either a specific radioimmunoassay or high-performance liquid chromatography method.

Introduction: Area under the concentration-time curve (AUC) has been advocated as a better parameter to monitor cyclosporine A than trough concentrations. Up to now, more than 100 equations to estimate AUC using a limited sampling strategy have been published, but not all have been validated.

Material And Methods: Eight equations for AUC0-12h and two for AUC0-8h were validated.

Therapeutic monitoring of antiepileptic drugs: a comparison between a Czech and a Swedish University Hospital.

Plasma concentrations obtained during routine therapeutic monitoring of antiepileptic drugs (AED) (N03A ATC group) were compared in patients treated with one or several AED in the University Hospitals in Ostrava, Czech Republic and Huddinge, Sweden. Request and reply forms for therapeutic drug monitoring (TDM) were used as a source of mean plasma concentrations (PC). The study included 2,824 adult out- and inpatients in Huddinge treated from 1995 to 1999 and 1,268 outpatients treated in Ostrava from 1993 to 2004.

The use of TDM data to assess the validity of defined daily doses of antiepileptics: a comparison between a Czech and Swedish University Hospital.

Prescribed daily doses (PDDs) of antiepileptic drugs (AED) (N03A ATC group) were recorded for drugs used in monotherapy or in combination therapy in the University Hospitals in Ostrava, Czech Republic and Huddinge, Sweden. Plasma concentrations were used as an indicator of the quality of treatment. PDDs were compared with the defined daily doses (DDDs) suggested by WHO in the ATC/DDD index 2005.
