Through the ages,it is believed that chewing gum helps in increasing concentration & losing calories-thus seconding Wrigley's tagline 'Gum is Good'.However,in the current scenario it is contended that gums can be one of the most effective vehicle for drug administration.On an average,it is found that a person chews gum for about 20 minutes.Thus,the average 'inside-the-mouth' time for chewing gum remains very high as compared to lozenges or chewable tablets/candies.Therefore,drugs required for local or direct action in the respiratory tract can be very well administered through chewing gums.Also,it is contended that the cheek walls are very well perfused & can therefore bring about excellent & quick absorption of drugs.Besides,drugs administered through chewing gum also do not undergo hepatic first pass effect-thus increasing the bioavailability of drug.
Currently,not many chewing gum brands in India are positioned on the health plank.However,the recent years saw the launch of products like Protex Happydent which is claimed to prevent tooth decay due to the presence of a special ingredient called 'Xylitol'.Also,Happydent White which contains sodium bi-carbonate helps to keep teeth clean & white.Other brands like Orbit also offer similar benefits & assist in maintaining oral hygiene.Though currently most of the brands are concentrating only on oral hygiene,there are also numerous opportunities in developing chewing gums with sustained release formulations,anti-tussives etc.
