Troche is a medicinal form of medication, also known as a tablet or pill, which is designed to dissolve slowly in the mouth or under the tongue. There are several synonyms for troche that can be used interchangeably in medical literature, including lozenge, pastille, tablet, or wafer. Lozenge is probably the most common term used to describe a troche, and it is often used to treat sore throats and coughs. A pastille is a similar medication that is chewed or dissolved in the mouth. Tablets and wafers are also used to administer medication in a slow and steady way, and they are frequently used in pain management or for treating certain medical conditions like angina or heart disease.
