Abstract
A method for preparing pharmaceutical formulations of poorly soluble drug substances in the form of concentrated solutions for filling soft gelatin capsules and solid dispersions and suspensions for filling hard gelatin capsules and compressing into tablets is provided. Pharmaceutical formulations of poorly soluble drug substances are also disclosed. The formulations include the sodium salt of the poorly soluble drug substance, a conversion aid such as PEG, polysorbate, a sugar alcohol (e.g. mannitol or xylitol), propylene glycol or transcutol, and, in some cases an excipient, such as dicalcium phosphate dihydrate, lactose monohydrate, or microcrystalline cellulose.
