Antibiotic Potency Testing: The Methods – Part 1

Using the Diffusion (Cylinder-Plate) Method 

Both the European Pharmacopoeia and the US Pharmacopeial Convention (USP) require testing of antibiotic potency using microbiological assays for some products. When the potency of an antibiotic is measured chemically, its concentration in solution is all that is determined. Conversely, a microbiological assay verifies the ability of the antibiotic to kill the target organisms, as well as the concentration at which the antibiotic will kill effectively.

A microbiological potency assay measures the effectiveness of an antibiotic by the degree of growth inhibition on susceptible strains of microorganisms at differing concentrations. One of the two methods defined in the pharmacopoeia to make this determination is the Diffusion (Cylinder-Plate) method.

Editorial: The Future of Pharma - Embracing a Changing Landscape

Stephan Kutzer, Alcami CEO & President, authored an article for manufacturing chemist's January 2017 issue titled "The Future of Pharma." The article discusses the future of the pharmaceutical industry, and embracing the changing landscape.

"If the pharmaceutical industry had to pick its favourite buzzwords from 2016, “innovation” would easily make the top five. Not necessarily because innovation exists in all corners of the industry, but because it is top of mind in nearly every area."

Elemental Impurities: The Risk-Based Approach

The U.S. Pharmacopeia (USP) intends to remove the existing wet chemistry heavy metals methods outlined in USP General Chapter <231> by January 2018. Although the existing wet chemistry methods have been in effect for nearly 100 years, the methods are non-specific and frequently fail to detect or underestimate the presence of some toxic elements that are potentially present in pharmaceutical ingredients. The USP requires Plasma Spectrometry (ICP-MS or ICP-OES) as the technique to screen and/or accurately quantitate the presence of any elemental impurities of interest.  From a compliance perspective, the new guidance for elemental impurities (USP<232>and ICH Q3D) only applies to the drug product.  There are currently two strategies to meet the requirements for elemental impurities, with the first being a Risk-Based approach.

ON-DEMAND WEBINAR: Demonstrate Abuse-Deterrent Properties in Opioid Formulations

Prescription opioid abuse has reached epidemic levels in the United States, with nearly 20,000 deaths in 2014 (the most recent year for which statistics are available) from unintentional overdose of prescription opioids and nearly 36,000 deaths in which prescription opioids were either directly or indirectly implicated. This issue has become a major regulatory focus over the last several years and has resulted in the issuance of FDA guidances requiring abuse-deterrent properties for new opioid drug formulation NDA’s (final guidance April 2015) and generic ANDA’s (draft guidance May 2016). A major component of proving the abuse-deterrent properties for a new formulation is the execution of in vitro manipulation and extraction studies, which companies are increasingly turning to CRO’s to perform.

The Effect of Abuse-Deterrent Formulations on Opioid Abuse

In 2011, the White House published “Epidemic: Responding to America's Prescription Drug Abuse Crisis,” which outlined a comprehensive strategy for responding to America’s prescription drug abuse crisis. This action was triggered by an alarming increase in drug overdose deaths in the United States from 1999 to 2010. During this time, overdose deaths from opioid pain relievers quadrupled, and have continued to increase.
