Which abbreviation represents syrup in medication terminology?

The abbreviation "syr" is used to denote syrup in medication terminology. Syrups are typically concentrated solutions of sugar in water, often combined with medicinal agents, and are employed in both prescription and over-the-counter medications to make them more palatable, especially for those who may have difficulty swallowing pills, such as children.

In contrast, other abbreviations in the choices represent different forms of medications. For instance, "tab" refers to tablets, which are solid doses of medication. "liq" stands for liquid, a broad term that can encompass various forms including solutions, suspensions, or syrups. "DS" is commonly used to mean double strength, often in the context of dosage forms, but does not specifically refer to syrup. Thus, "syr" distinctly identifies syrup and is the correct choice for this question.
