Abstrakt

The aim of this study was to develop a fast and reliable method for determination of tablet coating thickness. Tablets were coated with polymeric Pharmacoat® 606 in a laboratory coater. The coating thickness was measured by near-IR absorption of the coating material using calibration. The calibration and validation results afforded the following parameters: determination coefficient R2 > 0.97, the number of factors 6 and the standard error of cross-validation 5.4 μm at the coating thickness 25125 μm. The obtained results confirmed suitability of the method for evaluation of coating quality.
