What is the maximum quantity of codeine allowed in a Schedule III preparation?

In determining the maximum quantity of codeine allowed in a Schedule III preparation, it is based on federal regulations that categorize certain mixtures for safe use and control. For a combination product to be classified as a Schedule III substance, it can contain up to 1.8 grams of codeine per 100 milliliters or per 100 grams. This establishes a threshold intended to limit the quantity of codeine, thereby reducing the potential for abuse while still allowing for legitimate medical applications.

Option B states the correct maximum quantity allowed for codeine in such preparations, reinforcing the importance of adhering to regulatory standards in pharmacy practice. The use of this regulation ensures that medications are prescribed and dispensed responsibly, especially those with potential for misuse.

Other options listed either suggest lower or higher amounts, which do not meet the established guidelines set by law, making them incorrect in this context. The precise limits are crucial for compliance and ensuring patient safety.
