    摘要: The invention relates to the use of carboxylic acids incorporated as a catalyst in poly(orthoester)s and other acid labile polymers such that upon exposure to aqueous environments the acid catalyzes the erosion of the polymer matrix. The rate of release of a drug substance incorporated into or surrounded by the poly(orthoester) or other acid labile polymer can be controlled in that the drug is released as the polymer is eroded in response to the catalytic action of the acid incorporated therein.

    摘要: This invention involves complexes of quinoline carboxylic acid derivatives with guanidine and guanidine carbonate. The complexes have a greater solubility and dissolution rate when compared to the parent quinoline carboxylic acid derivatives and thus are more effective anti bacterials than the parent acids.
