This review covers all the aspects of medicated chewing gum (MCG) as a new drug delivery method, including the benefits and drawbacks, manufacturing methods, type of MCG, composition of chewing gum, evaluation parameters, factors that affected the release of API, its pharmaceutical significance, various marketed chewing gum and chewing gum packaging. Chewing gum as a drug delivery system has the potential to cure or prevent various indications, such as analgesic, CNS stimulation, smoking cessation, motion sickness, and treatment and prevention of dental caries or gingivitis. Pharmaceutical distribution to the oral mucosa can be made more convenient and enticing with the help of MCG.
