Troches is an alternate name used for solid dosage forms known as:

Suppositories are solid dosage forms intended for rectal or vaginal administration, designed to melt at body temperature. They differ significantly from lozenges in both route of administration and purpose, as they are used to deliver medication in a completely different physiological context.

Granules are small particles that can be used for various pharmaceutical formulations, often requiring further processing, such as mixing with liquids for administration. They do not dissolve slowly in the mouth like lozenges do and are typically not intended for direct oral consumption in their granular form.

Powders are dry, finely ground substances that can be used as active ingredients or for compounding. Like granules, powders require additional steps for administration, such as mixing with liquids, and do not provide the specific slow-dissolving characteristics associated with lozenges or troches.
