摘要：

Tablets containing anhydrous theophylline, a hygroscopic material such as magnesium chloride or potassium acetate, and other constituents were stored for 4 and 12 weeks under 90% relative humidity at 37 degrees C. During storage, whisker-like crystals appeared on the surface of the tablets. The crystals were observed under a scanning electron microscope. Changes were found in the physical properties of these tablets: crushing strength, friability, disintegration time and dissolution rate.
