Review: physical chemistry of solid dispersions

A drug's solubility is problematic if the required dose cannot dissolve into the available volume of gastrointestinal juices. A well-studied example of such a drug is itraconazole, which is a weak base that is expected to dissolve primarily in the stomach, with an aqueous solubility of 1 ng/ml at neutral pH, 4 µg/ml at pH 1 and a dose of 100 mg. [] Therefore, 25 L would be required to ...
