Abstract

Provided is an orally disintegrating tablet evaluating method includes: measuring the mass of tablet; placing the tablet on a preparation placement surface of a test solution supply unit; measuring a water absorption time for a test solution to penetrate from one end of the tablet in contact with the surface to the other end of the tablet; measuring the mass of the tablet for which the time for the solution to penetrate has been measured; and calculating the water absorption rate of the tablet by the following formula (1); wherein the tablet is evaluated based on a water absorption rate of the tablet of 0.004 g/sec:water absorption rate of tablet=(mass of tablet after measurement of time for solution to penetrate−mass of tablet before measurement of time for solution to penetrate)/(time for solution to penetrate from one end to other end)  (1).
