What is a common feature of compounding practices related to dangerous drugs?

Compounding practices related to dangerous drugs are required to be subject to rigorous testing for safety and effectiveness. This is essential to ensure that the compounded medications meet the required standards for quality, potency, purity, and safety. Proper testing helps to identify and mitigate any potential risks associated with the compounding process, ensuring that the final product is both safe for patient use and effective for its intended purpose.

Inherent in compounding practices is the necessity to tailor medications to meet specific patient needs, which could involve altering concentrations or combining different active ingredients. This requires adherence to strict guidelines and quality assurance processes, making rigorous testing a fundamental aspect of safe compounding practices.

The other options highlight approaches that would compromise safety and efficacy. Compounding should never be fully automated without any human intervention, as human oversight is critical in ensuring the quality of the final product. Speed should not be prioritized over safety, as this poses a risk to patients. Moreover, the practice of mixing multiple medications without proper oversight would contradict the principles of compounding, which emphasizes the necessity of skilled professionals in ensuring safe and effective medication preparation.
