A better recognition of the properties of materials is of great interest in pharmaceutical technology, and especially in the development of modern solid dosage forms. As an example, a knowledge of the force of adhesion of a mucoadhesive preparation is of considerable importance. The aim of the present study was to develop the calibrated equipment suitable for determination of the force of adhesion and for following the process of film deformation during testing. A new instrument is introduced, and the results are presented.
