Prediction of polymer mucoadhesiveness represents a fundamental task during evaluation of novel mucoadhesive dosage forms and new chemical entities. For this purpose, in the last 20–25 years, a very large number of works have been carried out for the development of in vitro mucoadhesive tests (2–8). Despite this great effort, the data Cited by: 4. Get this from a library!

The approach to evaluating the compatibility of polymer mixtures proposed by us for the first time using thermodynamic stability and the theory of solutions suggests that although giving non-equilibrium values of stability coefficients (as a consequence of long relaxation times of polymers), acoustic methods cannot be used in addition to static meth- ods for similar analyses [4, 6, 8, 9].Cited by: 1.

the polymer in water (which is performed during the acoustic measurements) can be expected to modify the polymer material since PLA and PLGA degrade in water via hydrolysis into lactic acid, and lactic and glycolic acids, respectively. The quoted degradation half-lives in water are around months for PLGA and over 12 months for PLA .
