CHEWING GUM: A MODERN ERA OF DRUG DELIVERY

Abstract

Chewing gum as a drug delivery system has many advantages over other oral dosage forms and oral route is the most preferred route amongst the patient and clinicians because the first pass metabolism can be avoided by the absorption of drug through buccal mucosa in the systemic circulation. It can be applied to cure and prevent the dental caries, pain, smoking cessation, obesity, xerostomia, motion sickness, acidity and specially diabetes. It has many advantages like fast onset of action, no first pass metabolism, patient compliance, taste masking, reduced risk of erosion of gastric mucosa, overdose and some marketing advantages. This review indicates that further study on medicated chewing gum can be used to improve it as a modern drug delivery.
