What is the purpose of a troche?

A troche is specifically designed as a lozenge that dissolves in the mouth, allowing for localized or systemic absorption of medication through the mucous membranes. This method of delivery is beneficial because it can provide a faster onset of action compared to other forms of medication, as the active ingredients enter the bloodstream directly. Troches can be formulated to administer a variety of medications, catering to the needs of patients who may have difficulty swallowing pills or prefer a different form of administration.

In contrast, a skin patch serves a different purpose by delivering medication transdermally, while a pill is typically ingested for effects on systemic health, and an injectable form involves direct entry into the bloodstream through a needle. Each of these forms serves distinct delivery mechanisms and therapeutic purposes, highlighting the unique characteristics of a troche as an oral mucosal dosage form.
