Stabilitásvizsgálatra

Stabilitásvizsgálatra, or stability testing, is a crucial process in various scientific and engineering disciplines, particularly in pharmacology, chemistry, and material science. It involves assessing how the properties of a substance or system change over time under the influence of various environmental factors such as temperature, humidity, light, and pressure. The primary goal of stability testing is to determine the shelf life of a product, understand its degradation pathways, and ensure its safety and efficacy throughout its intended storage period.

In the pharmaceutical industry, stability testing is mandated by regulatory bodies like the FDA and EMA. It involves storing drug products under controlled conditions for extended periods and periodically analyzing them for changes in their physical, chemical, and microbiological properties. This includes assessing factors like potency, purity, dissolution rates, and the formation of degradation products. The data generated from these tests are essential for establishing appropriate storage conditions and expiry dates, ensuring that patients receive safe and effective medications.

Beyond pharmaceuticals, stability testing is also vital in the food industry to determine the shelf life of food products and identify conditions that lead to spoilage. In materials science, it helps in understanding the long-term performance and durability of materials when exposed to environmental stresses. For example, testing the stability of polymers under UV radiation can predict their outdoor lifespan. The methodologies and conditions for stability testing are tailored to the specific application and the expected environmental exposures.
