MwPharm, therapeutic drug monitoring, digoxin, software

Digoxin is the oldest drug indicated for the treatment of systolic heart failure (HF). It is also useful in controlling excessive ventricular rate in the presence of atrial arrhythmias. Therapeutic drug monitoring (TDM) has become an integral part of its prescription, allowing to optimize therapy and to reduce the incidence of toxicity. Since 1991, the MwPharm software package (Mediware, Groningen, The Netherlands / Prague, Czech Republic) has been used for pharmacokinetic and pharmacodynamic (PK/PD) modelling in TDM, including digoxin. First Windows version with a broader spectrum was released in 2014, as a reaction of worse support of the DOS background on later versions of Windows. After its release, the company had decided to not develop DOS versions anymore, even though they are globally used with success. The aim of this study was to compare the usefulness of DOS and Windows version (WIN) of the MwPharm, and their prediction quality in TDM of digoxin.
