A method of monitoring a property of a dissolution of an at least partially solid dosage form during a dissolution process is disclosed. The method includes at least partially dissolving the dosage form, and during the dissolution of the dosage form, simultaneously monitoring the property of the dissolution of the dosage form in progress by low coherence interferometry.

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).

A device and a method for testing tablets are disclosed. The device for testing tablets includes a test chamber, which has a crusher jaw and, lying opposite the latter, a counter-jaw. The device has a movable sheet metal strip, which is designed to position a tablet for testing. The longitudinal axis of the movable sheet metal strip is at an angle of less than 90 to the longitudinal axis of the direction of movement of the crusher jaw, and the direction of movement of the sheet metal strip corresponds to the longitudinal axis of the sheet metal strip.
