Which medication class is used primarily to treat moderate to severe pain?

Narcotic analgesics, also known as opioids, are primarily used to manage moderate to severe pain. They work by binding to specific receptors in the brain and spinal cord, blocking the perception of pain and producing a sense of euphoria. Common examples include morphine, codeine, and oxycodone. Due to their efficacy in pain relief, they are typically prescribed when patients experience significant discomfort that cannot be managed effectively with other medications.

In contrast, non-narcotic analgesics are mainly used for mild to moderate pain and include over-the-counter medications such as acetaminophen and ibuprofen. Antipyretics are medications designed to reduce fever and may also provide some pain relief, but they are not the primary choice for treating severe pain. Hypnotics, on the other hand, are primarily prescribed to assist with sleep and are not intended for pain management. Therefore, the classification of narcotic analgesics as the preferred treatment option for moderate to severe pain is well-supported by their pharmacological effects and clinical use.
