Troches and lollipops are used to keep drugs in the mouth when local action is needed there. Troches also may be placed under the tongue and allowed to dissolve, which allows the medication to enter the bloodstream quickly and easily. Some troches can be chewed and swallowed by a patient who cannot or will not take a capsule or tablet. These dosage forms can be enhanced with natural sweeteners and pleasant-tasting flavors, making them ideal for geriatric and pediatric patients.
