What is the maximum amount of morphine allowed in a Schedule III preparation?

The maximum amount of morphine allowed in a Schedule III preparation is 500 mg per 100 mL. Schedule III controlled substances include certain narcotic medications that may be prescribed for medical use but are subject to more regulations than non-controlled substances.

In this specific case, the regulation allows for narcotic combinations, such as those containing morphine, to be classified under Schedule III as long as their concentration is within stipulated limits. The regulation permits the inclusion of up to 500 mg of morphine in that standard 100 mL dosage form, which enables pharmacists and healthcare providers to utilize this medication in liquid formulations safely without risking higher abuse potential inherent in more concentrated narcotics found in other schedules.
