ABSTRACT The content of chloramphenicol in chlordiazepoxide cream was determined by high performance liquid chromatography (HPLC), and the stability of this formulation was investigated by accelerated and long-term tests to ensure its safety and effectiveness. The results showed that its properties, content and microbiological limits met the requirements within 12 months stored at cold conditions except for shading and confinement, which can provide a basis for its optimal storage conditions and expiry date.
KEY WORDS chloramphenicol; chlordiazepoxide cream; high performance liquid chromatography; content determination; stability
