moistureThe impact of activity on drugs

In drug quality control and formulation research, water activity is sometimes an overlooked and underestimated parameter . In addition, it also provides key information for optimizing product stability. Deliquescence, solidification and agglomeration, dissolution, microbial sensitivityAPIDegradation and other issues can be addressed by determining the ideal water activity range of the product and using water activity measurement as a routine parameter for batch inspection. Due to the ideal range of water activity, most drugs also meet the requirement of reducing microbial limit testing, thereby saving time and reducing production costs.

Moisture content and water activity are parameters measured when solving different practical problems. However, the correlation between water content and the chemical, physical, or microbiological properties of drugs is not significant, while water activity can provide better correlation. The determination of water activity is non-destructive, time-saving, labor-saving, and has simple and inexpensive equipment. It is of great significance for the research and development of pharmaceutical products, control of production environments, selection of packaging materials, and preservation of finished pharmaceutical products.

However, in the actual research and production of the biopharmaceutical industry, research on the effects of water activity on the changes of active ingredients in drugs and its effective role in formulation studies has been ongoing. The control of water activity is beneficial for ensuring the stability of active ingredients in pharmaceutical products, reducing the risk of bacterial contamination in non sterile products, optimizing formulation, reducing clumping and coagulation, and controlling water migration. In short, the control and research of water activity are crucial for improving the quality of mass-produced products and are important quality parameters for pharmaceutical product quality control.

waterpartThe purpose of an activity meter

Firstly, optimize the product formula to enhance the antibacterial efficacy of the anti-corrosion system;

Secondly, reduce the degradation of active ingredients in the formula that are susceptible to chemical hydrolysis;

Third, reduce the possibility of microbial contamination of formulas, especially liquids, ointments, lotion and cream preparations; Fourthly, provide the principle basis for reducing microbiological testing, including reducing batch release testing and stability testing of products

Guanya brandBiopharmaceutical water activity meterProduct Introduction

The water activity meter developed by Shenzhen Guanya adopts multiple analysis and testing modes7A high-resolution LCD screen with full touch operation mode, which can display real-time data changes of sample temperature, activity value curve, activity value, temperature and other parameters during the analysis process. The entire testing process is fully automated, and after analysis, an automatic voice alarm is triggered. The instrument screen automatically locks the final data and stores the test data at the same time. No need for personnel to supervise or maintain the experimental process. After the experiment is completed, a dedicated micro printer will print out the detected valid data in real time for long-term preservation. You can also view and print historical test records in the history section.

The equipment is professionally designed with stable performance, high detection accuracy, short measurement time, and easy operation. By touching the color screen display, the screen backlight brightness can be set, achieving a friendly human-computer interaction interface. Multiple channels can be opened simultaneously to measure, measure or calibrate time10About minutes, the time can be set according to different tested objects. Long calibration cycle, no need for frequent calibration. Simultaneously equipped with print output function, curve drawing function, and upper computer data acquisition system. It can facilitate data recording and collection, which can be used for later data comparison and analysis.
