Background

There is renewed interest in the development of the Dried Blood Spot technique (DBS) for determining drug levels in blood samples. The benefits of this sampling technique for pre-clinical and clinical bioanalytical assays have been recognised by BASi®.

  • Refinement - elimination/reduction of rodent warming
  • Reduction - reduced volumes enables serial sampling from one rodent reducing animal numbers and eases sampling in paediatric studies
  • Reduced costs - animal numbers, test substance, simplified procedures (collection and laboratory), shipping and storage

Objective

To evaluate the use of DBS to determine diltiazem in human blood.
