Development and uniformity evaluation of low-dose medicated chewing gums prepared by compression method

Abstract

The aim of this work was to develop medicated chewing gums (MCGs) containing 10 mg of lysozyme hydrochloride (LH) and 20 mg of ascorbic acid (AsA) obtained by the compression method with Health in Gum® (HiG®) PWD 01 as a compressible gum base. Because of a low content of active ingredients, it was essential to choose the way of adding them to the tableting mass and evaluate their distribution homogeneity in the dosage units. The blends for compression were prepared by two methods: the first one was simple mixing of all components; the second one included the step of wet granulation of a three-component mixture – LH, sucralose and a taste additive.
