Expert Committee: Excipient Monographs 2

Coordinating Pharmacopoeia: European Pharmacopoeia

The revision to the harmonized standard for Gelatin has been approved by the Pharmacopeial Discussion Group (PDG) as described in its PDG sign-off cover sheet. Having reached Stage 4 (former Stage 6) of the PDG process, the Gelatin monograph has been formally approved by the Excipient Monographs 2 Expert Committee in accordance with the Rules and Procedures of the Council of Experts.

Changes from the current Gelatin monograph include:

  • Definition. Added the symbols  to USP local text “(including fish and poultry)”, and aligned the description with the PDG sign-off document.
  • Identification C. Changed the temperature from "0°" to "2° - 8°", based on the stakeholder's request and the agreement with the PDG. It was observed that some type of non-gelling gelatin cannot flow out immediately at 0° due to high viscosity of the gelatin solution.
  • Identification D. Changed the acceptance criteria from “A red color develops” to “A red to violet color develops” based on the observation and request from stakeholders.
  • Sulfur Dioxide. Described the Titrant as “0.1 N sodium hydroxide VS” according to USP style.Download the Gelatin monograph – Stage 4

Additionally, minor editorial changes have been made to update the monograph to current USP style.

The Gelatin monograph will be incorporated into and become official in the USP 43–NF 38.
