    Researchers evaluated coated aspirin tablet disintegration using Weibull distribution analysis. A new formulation parameter, the input value, was identified for assessing tablet quality when correlated with crushing strength.

    Area of Science:

    • Pharmaceutical Sciences
    • Materials Science

    Background:

    • Tablet disintegration is a critical factor in drug efficacy.
    • Understanding disintegration force development is essential for tablet formulation.
    • Existing methods for evaluating tablet properties can be enhanced.

    Purpose of the Study:

    • To evaluate coated aspirin tablet formulations based on disintegration force development.
    • To apply Weibull distribution analysis to disintegrating force-time curves.
    • To identify novel formulation parameters for tablet evaluation.

    Main Methods:

    • Coated aspirin tablet formulations were analyzed.
    • Disintegrating force-time data were collected and treated using Weibull distribution.
    • Key parameters including maximum force, time to 63.2% force (tau d), shape parameter, lag time, and input value were determined.

    Main Results:

    • Weibull distribution successfully characterized tablet disintegration patterns.
    • The input value, representing the force development rate at tau d, emerged as a significant parameter.
    • Correlation between input value and crushing strength provided a comprehensive evaluation.

    Conclusions:

    • The input value is proposed as a new, valuable parameter for tablet formulation assessment.
    • Integrating force development rate analysis offers a robust method for evaluating tablet quality.
    • This approach aids in optimizing coated aspirin tablet formulations.
