Expert Committee: Chemical Medicines Monographs 1

In accordance with section 7.04 (c) of the 2015–2020 Rules and Procedures of the Council of Experts, this is to provide notice that the Chemical Medicines Monographs 1 Expert Committee intends to revise the Amoxicillin Tablets monograph.

Based on comments received the Expert Committee intends to revise the monograph as follows:
•    Update the impurity table to show that amoxicillin related compound J is a mixture of co-oligomers by including the relative retention times for two co-oligomers
•    Delete the relative response factors from the table based on FDA approved acceptance criteria
•    Delete the second name for amoxicillin related compound J in the table as it is not sufficiently descriptive
•    Update the table footnote about related compound J to indicate that the limit is for the sum of  responses from the co-oligomers of related compound J, based on approved limits
•    Widen the limits for amoxicillin related compound C, D, K and J  based on approved limits

The process for and timing of the revision will be determined following additional considerations by the Expert Committee and USP staff.
