Prediction of tablets disintegration times using near-infrared diffuse reflectance spectroscopy as a nondestructive...

Area of Science:

• Pharmaceutical Sciences
• Analytical Chemistry
• Spectroscopy

Background:

• Tablet disintegration time is a critical quality attribute in pharmaceutical manufacturing.
• Traditional methods for measuring disintegration time are often time-consuming and destructive.
• Near-infrared (NIR) spectroscopy presents a potential alternative for rapid, nondestructive analysis.

Purpose of the Study:

• To utilize near-infrared (NIR) reflectance spectroscopy for measuring tablet disintegration time.
• To calibrate NIR data against laboratory equipment measurements.
• To develop, validate, and test a predictive model for tablet disintegration time.

Main Methods:

• Preparation of seven theophylline tablet formulations and five placebo formulations with varying disintegration times.
• Measurement of disintegration time using laboratory equipment and NIR diffuse reflectance spectroscopy.
• Application of linear regression, quadratic, cubic, and partial least square techniques for data analysis.

Main Results:

• A positive correlation was observed between increased disintegration time and increased NIR absorbance.
• Model equations were developed using various regression techniques, correlating laboratory and NIR data.
• NIR-based disintegration time measurements showed results comparable to traditional laboratory tests.

Conclusions:

• Near-infrared diffuse reflectance spectroscopy is a viable, nondestructive alternative for measuring tablet disintegration time.
• The developed models demonstrate the potential for accurate prediction of tablet disintegration.
• NIR spectroscopy can enhance efficiency and quality control in pharmaceutical tablet analysis.
