Reducing microbial contamination via sterile risk assessment

Reducing microbial contamination via sterile risk assessment

Issue 2 2015, Microbiology / RMMs / 20 April 2015 / Guenther Gapp, Lachman Consulting Ltd/Independent Consultant

Several years ago, microbiologist Guenther Gapp created a new sterile risk assessment tool (based on a hazard operability analysis [HAZOP] approach) to identify and reduce the microbial contamination and compliance risk of aseptically-produced sterile products and production plants. The following article describes the operating principle of three risk analysis tools with a special focus on the revised 2015 edition. This latest edition incorporates the improvements that have been implemented in recent years, which make the tool more applicable and thus valuable for the user…


The role of water activity in the microbial stability of non-sterile pharmaceutical drug products

Issue 1 2015 / 10 March 2015 / Tony Cundell, Consulting Microbiologist, Scarsdale

Aqueous, multiple-use, non-sterile drug products are susceptible to microbial contamination during their shelf life. To protect these products from this potential hazard to patients, they are formulated with antimicrobial preservatives. Other product attributes employed using the hurdle concept to prevent microbial contamination include: low pH, low redox potential, reduced storage temperature, packaging that protects the product and low water activity. Water activity, or Aw, is a measure of available water and when applied to a non-sterile pharmaceutical drug products is a critical physical attribute that determines whether the product will support the growth of microorganisms. Given the knowledge of the minimum water activity for the growth of bacteria, yeast and mold, the microbial stability of a drug product can be determined. This knowledge can be used to set risk-based microbial specification and release and stability testing programs for different dosage forms. This review article will discuss the role of reduced water activity in imparting microbial stability to non-sterile drug products…

Microbiology Series: Antimicrobial delivery

Issue 2 2014, Microbiology / RMMs / 15 April 2014 / Joshua Boateng and Harshavardhan Pawar, Department of Pharmaceutical Chemical and Environmental Sciences, Faculty of Engineering and Science, University of Greenwich

Antimicrobial drugs form a significant aspect of disease therapy and are a major means of treating bacterial, fungal and viral infections. The issue of antimicrobial therapy is of current interest and clinical concern. This is mainly due to two key reasons; (i) persistent emergence of microbial resistant strains and (ii) the significant reduction in the rate of successful discovery new generations of more potent antibiotics to combat this resistance epidemic (especially in bacteria).
