It is a novel drug delivery system containing masticatory gum base with pharmacologically active ingredient and intended to use for local treatment of mouth diseases or systemic absorption through oral mucosa. Chewing gum is the convenient and effective means of rapidly administering chlorpheniramine maleate (CPM), as it is readily soluble, permeable, and used to relieve symptoms of allergy, hay fever, and common cold. In the present study, medicated chewing gum of CPM has been formulated using gum base, sorbitol, mannitol, magnesium stearate, lecithin, and menthol. This medicated chewing gum was prepared by direct compression method and formulated using various compositions of gum base and lecithin such as 30–35–40% and 5–10–15% accordingly. In the formulation, soya lecithin was used as a plasticizer and it was found that it acted on the drug release to some extent. When concentration of soya lecithin was increased, drug release was also found to be increased.
