Introduction: Amorphous solid dispersions are considered as one of the most powerful strategies to formulate poorly soluble drugs. They are made up of an active pharmaceutical ingredient (API) dispersed at the molecular level in an amorphous polymeric carrier. As the latter component constitutes the largest part of the formulation, its characteristics will contribute to a large extent to the properties and behavior of the solid dispersion. Areas covered: Amorphous polymers are most often used...

In the present study, the effect of Hydroxy Propyl Methyl Cellulose (HPMC) on the crystallization of ortho-aminobenzoic acid (OABA) was investigated by seeded and unseeded cooling crystallization experiments. The influence of HPMC on the induction time, crystal shape of Forms I and II of OABA and the polymorphic transformation time was studied. Furthermore, the capability of HPMC to inhibit growth of Form I was evaluated quantitatively and modelled using population balance equations (PBE)...
