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…
