ABSTRACT
Dosage forms that dissolve slowly in the mouth, or that can be easily chewed and
swallowed, are gaining in popularity, especially among pediatric patients. Hard (com-
pressed or molded) preparations of this dosage form are called lozenges, troches, or
drops. Soft (molded) lozenges/troches are often called pastilles, and chewable, gelatin-
based lozenges/troches are often called gummy, novelty-shaped products. The term
lozenge will be used in this chapter to refer to all variations of the dosage form.
