Determination of Metabolically Unstable Drugs in Blood by Heat-Stabilized DBS and LC-MS/MS
Charlotta Göransson; Karl Sköld; David Zeeberg; Gunnar Hägglund; Eskil Hermansson; Peter Abrahamsson and Martin Ahnoff

The aims of this work were to investigate drug stability prior to, during and after blood spot sampling, using procaine, prulofloxacine, esmolol, and acetylsalisylic acid as examples of drug compounds with limited stability and to compare conventional DBS sampling procedure with DBS sampling including heat stabilization.

Pharmacokinetic Delivery and Metabolizing Rate of Nicardipine Incorporated in Hydrophilic and Hydrophobic Cyclodextrins using Two-Compartment Model
Sergey Shityakov and Carola Förster.

The dispersion routes of cyclodextrin complexes with nicardipine (NC), such as hydrophilic hydroxypropyl-ß-cyclodextrin (NC/HPßCD) and hydrophobic triacetyl-ß-cyclodextrin (NC/TAßCD), through the body for controlled drug delivery and sustained release have been examined.
