Essential Requirements for Conducting Stability studies on Pharmaceuticals

The prime objective of conductingstability studieson pharmaceutical dosage forms is to define the shelf life under recommended storage conditions. In the interest of patient safety the dosage form should be guaranteed for its quality, safety and efficacy throughout its shelf life under prescribed storage conditions. The shelf life should be decided taking into consideration the climatic zones in which the product is expected to be marketed.

的混合因素th的稳定性e pharmaceutical formulation

Environmental Factors- 温度，湿度和光线照射

Ingredients- 活性药物物质的化学和物理性质以及赋形剂

Manufacturing Process– the conditions to which the ingredients are exposed during manufacturing can have significant influence on formulation stability

用于包装的材料- 包装材料和容器封闭系统的性质和兼容性。在整个保质期内递送药物的包装材料的相互作用的可能性需要适当的调查。

Methodology

稳定性研究are based on application of validated methods of analysis for evaluation of physical, chemical, biological and microbiological characteristics. Commonly evaluated parameters are assay or potency, concentration of decomposition products, hardness, disintegration, dissolution rate, etc. Efficacy of additives and antimicrobial agents is also determined to ascertain that there is no loss during the shelf life period.

研究类型

稳定性测试在不同阶段的制造和释放药物产品中是必要的

Development Phase

Accelerated stability tests are designed to increase the physicochemical degradation of the pharmaceutical formulation. Such tests help evaluate alternate formulations, packaging materials and manufacturing processes. Such studies also help predict the shelf life. Accelerated studies data should also be supported by simultaneous real-time studies

Dossier Registration

Drug regulatory authorities require manufacturer to submit information on the product stability of the final dosage form in its container and packing. The data should be based on both accelerated and real-time studies. Submitted data should also be supplemented with published data if available on the product or its ingredients.

后登记期

Data submitted to registration body on the expiry date by the manufacturer is required to be substantiated by real-time stability studies Results of ongoing stability studies are verified in the course of GMP inspections

Post-registration additional data are required to be submitted to the regulating authorities whenever major modifications are adopted in the formulation’s manufacturing process or packaging.
