Final answer:
The United States Pharmacopeia (USP) content uniformity test for tablets is used to ensure potency. (option C is the correct answer).
Step-by-step explanation:
The United States Pharmacopeia (USP) content uniformity test for tablets is used to ensure potency. The content uniformity test checks for consistent and appropriate levels of the active pharmaceutical ingredient (API) in each tablet. It measures the uniformity of drug content among different tablets within a batch, ensuring that each tablet delivers the intended dose of the medication.
Potency, in this context, refers to the concentration of the active substance, and the content uniformity test helps guarantee that each tablet meets the required standard, ensuring efficacy and therapeutic reliability.
By employing the USP content uniformity test, pharmaceutical manufacturers aim to maintain the quality of potency in tablet formulations, assuring that each tablet delivers the intended dosage of the active ingredient, contributing to the overall safety and effectiveness of the medication.
