ABSTRACT
OBJECTIVE: To provide reference and consideration for pharmaceutical development by expounding the basic considerations for the selection of freeze-dried injection excipients. METHODS: The excipients in freeze-dried injections approved by FDA in recent years have been listed, and the composition of excipients in the preparations and the maximum amount of excipients contained were summarized. The issues to be considered in the selection of freeze-dried injections were discussed. RESULTS: One quarter of the freeze-dried injections that have been marketed do not use excipients, while the most commonly used excipients are bulking agents, buffering agents and pH adjusters. Other excipients include solubilizing agent, antioxidants, etc.. CONCLUSION: The selection of freeze-dried injection excipients should focus on safety, formulation rationality, functionality-related characteristics and control of excipients.
ABSTRACT
Oral film is a new type of oral preparation. Due to portability, simple preparation process and good clinical compliance, oral films have become the focus of novel drug delivery system in recent years. Meanwhile, oral films have been gradually used in the development of Chinese medicine preparations. According to the application and approval situation of different types of oral films both at home and abroad in recent years, their research and development status was analyzed, including the basic concept, formulation, manufacturing process and quality control, as well as related progress and development prospects of oral films applied in traditional Chinese medicine. Some suggestions on the technical evaluation of oral films were put forward by considering specific requirements from regulatory agencies. This paper could provide some references for the development and evaluation of oral films. Due to the complexity of the drug substances and the particularity of the drug product, the development and application of oral films in traditional Chinese medicine are still faced with opportunity and challenges.
