Which dosage form may have a hard or gummy consistency and is related to lozenges?

• A. Troches
• B. Lozenges
• C. Ointments
• D. Creams

Answer: (A)

Troches are molded oral dosage forms designed to dissolve in the mouth, releasing the medication as they go. The base used in troches can be formulated to be either hard or gummy, giving a range of textures from firm to chewy. This flexibility in texture is why troches are described as having a hard or gummy consistency and are closely related to lozenges, which serve the same purpose of delivering medicine via dissolution in the oral cavity. Ointments and creams are topical semisolid preparations intended for skin or mucous membranes and are not meant to dissolve in the mouth, so they don’t fit this description.
