Formulation and processing factors influencing the adhesion of film coats to tablet cores.

abstract：INTRODUCTION:Theoretical models of the freeze-drying process are potentially useful to guide the design of a freeze-drying process as well as to obtain information not readily accessible by direct experimentation, such as moisture distribution and glass transition temperature, Tg, within a vial during processing. Previ...
