Which of the following is an example of a lozenge?

A lozenge is a small, flavored tablet that dissolves slowly in the mouth, allowing for medication or soothing agents to be released gradually. Cough drops are a specific type of lozenge that are commonly used to help relieve throat irritation or cough symptoms. Their design and purpose align perfectly with what constitutes a lozenge, making them the correct example among the provided choices.

In contrast, the other options do not fit the definition of lozenges. A pill is typically a solid dosage form that is swallowed whole and does not dissolve gradually in the mouth. Syrups are liquid medications meant to be ingested rather than dissolved, and injections are a method of delivering medication directly into the body through a needle, which is entirely different from the concept of oral dissolvable forms like lozenges. Thus, the best example of a lozenge within the choices is indeed a cough drop.
