Importance of the field: Over the years, patient convenience and patient compliance-orientated research in the field of drug delivery has resulted in bringing out potential innovative drug delivery options. Out of which, medicated chewing gum (MCG) offers a highly convenient patient-compliant way of dosing medications, not only for special population groups with swallowing difficulties such as children and the elderly, but also for the general population, including the young generation.
Areas covered in this review: In this review, various formulation ingredients, different manufacturing processes, and assessment of in vivo and in vitro drug release from MCG are thoroughly discussed along with the therapeutic potential and limitations of MCG.
What the reader will gain: Readers will gain knowledge about the rationale and prominent formulation and performance evaluation strategies behind chewing gum as a drug delivery system.
Take home message: The availability of directly compressible co-processed gum material enables rapid, safe and low-cost development of MCG as a drug delivery option. By MCG formulation, revitalization of old products and reformulation of new patented products is possible, to differentiate them from upcoming generics competition in the market.
