Lozenges are chewable solid device dosage forms, wherever the drug is loaded inside of a caramel base designed up of sugar and gum; the latter presents cohesiveness and strength for the lozenge and allows gradual release from the drug.

A drug might have more than one application variety if it's different dosage forms or routes of administration. In Medications@FDA, you could find the here NDA number under the column named "FDA Software."
