Preservative free ophthalmic oxazolidinone antibiotic drug delivery systems

摘要

There is provided a pharmaceutical preservative free composition suitable for topical administration to an eye, the composition comprising (a) an oxazolidinone antimicrobial drug, for example linezolid, in a therapeutically or prophylactically effective drug concentration that is above the practical limit of solubility of the drug in a substantially isotonic aqueous solution at a physiologically compatible pH, and (b) a pharmaceutically acceptable cyclodextrin compound in a concentration sufficient to maintain the drug in solution at such a drug concentration. The composition is particularly useful for the treatment and/or prevention of eye infections due to gram positive bacteria.
