ANTIBIOTIC FORMULATION AND A METHOD OF MAKING THIS FORMULATION

摘要

An antibiotic formulation in a true solution is provided. This formulation includes an antibiotic and N-methyl-2-pyrrolidone. It also may include a preservative, an antioxidant, and/or an additive. The antibiotic is a beta lactam, such as a penicillin, a cephalosporin, other beta lactams, or combinations thereof. The formulation is made by dissolving the antibiotic in the N-methyl-2-pyrrolidone. The antibiotic formulation is suitable for use at temperatures below about 0 °C and without agitation. Further, the antibiotic formulation in true solution can be made with non-sterile ingredients and can be filtered to remove impurities.
