Final answer:
Pharmacies may compound narcotic controlled substances pursuant to a prescription as long as the concentration is not greater than the maximum allowed limit. The specific maximum concentration limit depends on the particular substance and regulations set by governing bodies such as the FDA or DEA.
Step-by-step explanation:
Pharmacies may compound narcotic controlled substances pursuant to a prescription as long as the concentration is not greater than the maximum allowed limit.
The specific maximum concentration limit for a narcotic controlled substance depends on the particular substance and regulations set by the governing bodies such as the Food and Drug Administration (FDA) or Drug Enforcement Administration (DEA). For example, the DEA classifies hydrocodone combination products as Schedule II drugs and limits the concentration of hydrocodone to 15 milligrams or less per dosage unit to be dispensed as a Schedule III drug.
It is important for pharmacies and healthcare professionals to follow these regulations to ensure the safe and appropriate use of narcotic controlled substances.
