Troches or lozenges are designed to deliver the medication to the locally affected area, specifically, the
throat. Through this, the highest concentration can be achieved where it is needed (throat) and minimized
where it is not needed (absorbed via the stomach and firther along the digestive tract).
As such these products should be placed far back into the throat and allowed to dissolve, releasing its medication.
The normal tablet shaped lozenges may present a choking hazard when placed at the back of the throat.
S.P. Troche is designed with a hole in the middle, with an enlarged outer diameter. The bigger diameter reduces the
choking risk. Moreover, should any accidental lodging at the thorat happens, breathing is still facilitated through
Eventually when the troche has been dissolved sufficiently, the troche can be easily crushed with a swallowing action
thereby restoring normal airway patency.
