Which abbreviation is used specifically for medicine that is intended for topical application?

The abbreviation that represents medicine intended for topical application is "ointment," often abbreviated as "ointment" or "oint." This form of medication is specifically designed for application on the skin or mucous membranes, delivering active ingredients directly to the affected area. Ointments typically have a thicker consistency and can provide a protective barrier, which helps in the treatment of various skin conditions.

In contrast, the other abbreviations serve different purposes. The abbreviation for "liq" stands for liquid, which can refer to any medication in a liquid form and is not specifically for topical use. "Tab" is short for tablet, denoting solid oral medications that are ingested rather than applied to the skin. Finally, "syr" refers to syrup, which is also a liquid formulation taken orally, thus not applicable for topical application. Therefore, "oint" is correctly associated with topical medications, while the other choices represent forms that are meant for systemic or oral use.
