STABLE AQUEOUS DRUG SUSPENSIONS

摘要

Finely divided drug particles are coated with a lipid or bioadhesive polymer to form microspheres (226) having a particle size of about 550 micrometers or less, and coated with two or more enteric coatings, at least one of which is water insoluble, to form microcapsules. The resultant microcapsules can be suspended in an aqueous solution to form stable oral doses of the drug.
