There is provided a pharmaceutical composition for therapeutic or prophylactic administration to a subject having an infective disease or condition or at risk thereof. The composition comprises an aqueous carrier having in solution therein (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 intravenous delivery of the drug.

Cette composition comprend un excipient aqueux comprenant dans une solution : (a) un médicament antimicrobien à base d'oxazolidinone, par exemple la linézolide, dans une concentration de médicament efficace sur le plan thérapeutique et sur le plan prophylactique se situant au dessus de la limite pratique de solubilité du médicament dans une solution aqueuse sensiblement isotonique à un pH compatible sur le plan physiologique, et (b) un composé cyclodextrine pharmaceutiquement acceptable en une concentration suffisante pour maintenir le médicament en solution à une telle concentration de médicament. Cette composition est particulièrement utile pour effectuer une administration intraveineuse du médicament.
