What does the manufacturing of drugs involve?

Manufacturing of drugs encompasses a comprehensive process that includes several critical steps to ensure the final product is safe, effective, and of high quality. The correct answer highlights that drug manufacturing involves packing, labeling, and filling. These steps are vital components of the overall manufacturing process and must adhere to strict regulatory standards.

Packing refers to the process of preparing the drug for distribution, which ensures that the product is protected during transportation and storage. Labeling is essential for providing necessary information to healthcare professionals and patients, including dosage instructions, potential side effects, and storage conditions. Filling involves placing the drug into the appropriate containers, such as bottles or blister packs, which is critical for maintaining the drug's integrity and ensuring proper dosages.

The other options do not accurately represent the comprehensive nature of drug manufacturing. Merely stating "only packaging" or "only tableting" ignores the broader aspects involved, while claiming "manufacturing requires no specific steps" overlooks the crucial regulatory requirements and guidelines that govern the manufacturing process. Each of these steps plays a significant role in ensuring quality control and compliance with safety standards in the pharmaceutical industry.
