Abstract

La présente invention concerne une composition pharmaceutique de céfpirome et de tazobactum combinés en une dose fixe et de linézolide sous forme de dose injectable. Le tazobactum de la composition agit comme un inhibiteur enzymatique qui accentue l'activité antibactérienne du céfpirome en inhibant des bêtalactamases tels que les céphalosporinases, groupe 1, des TEM-bêtalactamases, groupe 2br et les métallo-bêtalactamases, groupe 3. Les principes actifs sont constitués fondamentalement par des antibiotiques bêtalactames pris dans le cefpirome et le tazobactum en association avec un autre médicament, le linezolide, oxazilidone faisant partie d'une nouvelle classe d'antibactériens exceptionnellement efficace contre MRSA, VRSA, E-faecalis et les bactéroïdes, alors que le cefpirome présente une activité plus faible. La composition de la présente invention pourrait jouer un rôle utile dans des cas critiques comme thérapie empirique.
