EPR in Pharma

Pharmaceutical Applications of EPR

Optimizing Stability and Shelf-Life

Forced degradation (stress testing) is routinely used in pharmaceutical development to predict the stability of drug products that affects purity, effectiveness, and safety. In stress testing the drug product is exposed to heat, light or chemical agents with the goals being:

  • Understanding degradation pathways
  • Determining the intrinsic stability and shelf-life
  • Developing stable formulations
  • Evaluating antioxidant efficiency

Product degradation often involves a free radical pathway therefore identifying the radical intermediates is extremely important. In addition, antioxidants’ efficiency in drug formulations is characterized by the ability to scavenge the free radicals and eliminate stability issues.
