A new Turkish pharmacokinetics software program for therapeutic drug monitoring of theophylline
Öz
In this study, it was aimed to develop a Turkish software with pharmacokinetic (PK) data for therapeutic drug monitoring and IV dose adjustment of narrow therapeutic index theophylline.
The study involved three groups, each comprising two rabbits The dose required for the target concentration (15µg/mL) was calculated with the developed program according to the weight of the rabbits in the first group. Blood samples taken at certain times were analyzed by validated HPLC method to calculate the elimination rate constant (ke) after IV bolus administration. The r2 values for ke were found to be 0.86 and 0.95. The second dose calculated according to revised PK findings was administered and blood samples were taken. When the analyzed results and theoretical results were compared, the deviation was found to be 5.53% and 8.795%. The findings were taken as the population PK for other applications.
IV multiple dose bolus and IV fast-slow combined infusion were administered to the second group and the third group, respectively. The results obtained from the analysis of blood samples taken at the times determined according to the application were compared with the theoretical results.
As a result, although there is a high difference between theory and practice at low concentrations, there is very little variation at high concentrations. By using this program, it has been achieved to keep theophylline at the desired level without reaching the minimum toxic concentration and without falling below the minimum effective concentration. It is thought that deviations will be reduced with larger samples.
