Stability Studies

Pharmaceutical stability testing is conducted to determine how the quality of API, drug substance or drug product varies with time under the influence of environmental factors such as temperature, humidity and light. These studies also help determine optimal storage conditions, product quality and expiration date(s). The ICH Guideline Q1A is the consensus document for performing stability studies. In addition to the traditional shelf-life stability studies, Avista Pharma routinely performs specialized studies designed for individual products, performance requirements, regions and study goals.
