What defines a syrup in pharmaceutical terms?

In pharmaceutical terminology, a syrup is specifically defined as a medication that is dissolved in a concentrated sugar solution. This concentrated sugar solution not only serves as a solvent but also helps mask the taste of the medication, making it more palatable, especially for pediatric patients. The high sugar content in syrups also acts as a preservative, contributing to the stability and longevity of the formulation.

The other options describe different formulations or delivery methods but do not correctly define a syrup. A solid compressed dosage form refers to tablets or pills, an alcohol extract from a plant relates to tinctures or extracts, and a transdermal delivery method pertains to the application of medication through the skin for systemic absorption. Only the definition of a syrup accurately focuses on the combination of medication with a sugar solution, highlighting its unique properties within pharmacy practice.
