Which medication is controlled and classified as an opioid analgesic?

The classification of medications is based on their therapeutic effects and the regulations governing their use. An opioid analgesic is a category of medication known for its pain-relieving properties, derived from opiates or synthesized to mimic the effects of opium.

Acetaminophen with Codeine Phosphate is the correct answer because it contains codeine, which is classified as an opioid. Codeine works on the central nervous system to reduce the perception of pain. Due to its potential for abuse and dependence, this medication is regulated as a controlled substance.

In contrast, the other medications listed do not fall under the category of opioid analgesics. Insulin Detemir is a long-acting insulin used to manage diabetes, primarily focused on regulating blood glucose levels rather than providing pain relief. Fluticasone propionate is a corticosteroid used to treat allergic and inflammatory conditions, such as asthma and allergies, rather than pain management. Amoxicillin is an antibiotic used to treat bacterial infections and is not classified as an analgesic at all.

Understanding the specific classes and actions of these medications is crucial for safe and effective pharmaceutical care.
