Key Elements of Science & Standards Division: Organization Flow
10
Drivers for Change Increase/improve interface between different parts of USP Increase efficiency on work flow within SSD –External to USP –Internal within USP Expert Committees were recently restructured to manage monographs and reference standards To make project ownership for each product clear (single point of accountability in the context of the team) Maximize capacity of our work load (identify constraints and provide solutions)
11
Products (monographs, reference materials) to our customers are synchronized and reference standards are available as early as possible There is a portfolio owner for each segment of the portfolio for Small Molecules, Biologics, Excipients, Dietary Supplements, Food Ingredients, General Chapters/Pharmacists’ Pharmacopeia, Healthcare Quality Standards A uniform criteria for priority setting.

Drug Product Monographs and General Chapters

A PBM can include: –Specified tests Identification, Assay, others –Specific acceptance criteria 97%-103%, NMT 0.1%, others –Criteria-based procedures with: Procedure Performance Measures (Precision, accuracy, others) Procedure Performance Acceptance Criteria (% RSD, Bias, R 2, others) Performance Based Monograph

Glutathione Example: Assay
21
USP General Chapter Validation of Compendial Procedures defines the critical validation parameters necessary to validate a procedure. Pre-set criteria assure that an acceptable procedure will reliably assess whether an article meets acceptance criteria of its Tests. USP now terms these criteria as Procedure Performance Measures (PPM) and the Procedure Performance Acceptance Criteria (PPAC). PPM and PPAC may be used to determine suitability of multiple acceptable procedures. PPMs and PPACs

USP Medicines Compendium: www.usp-mc.org
24
Key Points About the Medicines Compendium MC is applicable to medicines legally marketed outside of the US; USP-NF covers articles legally marketed in the US Science based Authoritative, not official; the approval by the Council of Experts makes it authoritative Supplements donor model Helps modernize USP-NF Experimental, unique, and innovative
