Greater collaboration and understanding are needed to ensure the correct grade of excipient is used in drug products.
USP Issues Change to Viscosity Reference in Monographs
June 5th 2012The United States Pharmacopeia has stated that references to General Chapter <911> "Viscosity" will be changed to General Chapter <911> "Viscosity-Capillary Viscometer Methods," <912> "Rotational Rheometer Methods," or <913> "Rolling Ball Viscometer Method."
USP Announces Proposed Standard for Supply-Chain Integrity
January 12th 2012The US Pharmacopeia announced a draft standard containing best practices for ensuring that drugs can be traced to their original manufacturer, are not counterfeited or adulterated, and can be transported to their intended destination without compromising quality.
Addressing Elemental Impurity Limits with ICP–OES and ICP–MS
November 1st 2011The US Pharmacopeia (USP) proposes to lower the maximum permissible limits of trace elements in pharmaceuticals and recommends that impurities be measured through automated instrumentation-based methods. The proposed regulations specify inductively coupled plasma–mass spectrometry (ICP–MS) and inductively coupled plasma–optical emission spectrometry (ICP–OES) as the techniques of choice. This article discusses the benefits of ICP–MS and ICP–OES for the accurate detection of trace elements in pharmaceutical products, in compliance with the proposed USP chapters.
