Which of the following is an oral dosage form?

Rationale

Troche is an oral dosage form.

A troche is designed to dissolve in the mouth, releasing medication for oral absorption, making it a suitable form for delivering drugs via the oral route. This characteristic distinguishes it from other topical dosage forms that are not intended for oral consumption.

A (Troche) CORRECT

As mentioned, a troche is specifically formulated for oral administration, allowing the medication to be absorbed through the mucous membranes in the mouth. This makes it an effective method for delivering certain medications, particularly for patients who may have difficulty swallowing pills.

B (Unguent) YOUR ANSWER

An unguent is a topical preparation, often oily or greasy, designed for application to the skin or mucous membranes. Its primary purpose is to provide a protective barrier or to deliver medication locally rather than for oral ingestion.

C (Collodion) YOUR ANSWER

Collodion is a liquid preparation typically used for topical applications, often to form a protective film over a wound. It is not meant to be taken orally and is used primarily for its adhesive properties on the skin.

D (Liniment) YOUR ANSWER

Liniments are also topical preparations, usually containing alcohol or oil, intended for application to the skin to relieve pain or inflammation. Like collodion and unguent, liniments are not suitable for oral use, as they are meant for external application.

Conclusion

In summary, among the given choices, a troche stands out as the only oral dosage form, specifically designed for dissolution and absorption in the mouth. The other options—unguent, collodion, and liniment—are all topical preparations intended for external application, highlighting the importance of distinguishing between oral and topical dosage forms in pharmacology.
