ABSTRACT
Objective: To predict the optimal single-batch production and annual production batches for five oral solutions in order to support equipment upgrade and control reasonable cost as well as provide reference for optimizing production management of new preparation room. Methods: The clinical use of the five oral solutions in four consecutive validity periods was retrospectively analyzed. Decision analysis was used to predict the optimal single-batch production and annual production batches for the five oral solutions. The weight coefficient was adjusted according to the clinical characteristics of each preparation. Results: The optimal single-batch produc-tion for the five oral solutions was five to seven times larger than the current scale while the annual production batches were greatly re-duced. In particular, compound ammonium chloride and glycyrrhiza oral solution ( formerly known as brown mixture) were reduced from 95 batches to 13 batches per year. Conclusion: The optimal prediction can provide reference for the appropriate adjustment of production scale of hospital preparations to lower the cost of single packaging production. At the same time, it is also beneficial to the overall management of production equipment selection and future scale design for new preparation room.
