Abstract: The invention describes a pharmaceutical composition to combat multiple-drug-resistant bacteria in non-ocular infective conditions. Compositions comprising glycopeptides, in particular vancomycin, and cephalosporins, in particular ceftriaxone, are disclosed. Such compositions are found to be useful for parenteral administration for hospitalized patients with serious infections. Specifically, this invention also discloses a pharmaceutical composition further including an excipient such as CVMC agent and is available in dry powder form for reconstitution before injection with a suitable solvent. The pharmaceutical compositions of this invention have been found normally to enhance resistance to precipitation in solutions to be administered parenterally. The invention also gives details of the dosage forms stored in sealed containers to be reconstituted before use.
