Analgesics are classified into different types based on their mechanism of action:
Non-opioid Analgesics: These include acetaminophen and NSAIDs like ibuprofen and aspirin. They are commonly used for mild to moderate pain and have anti-inflammatory properties. Opioid Analgesics: Medications such as morphine, oxycodone, and fentanyl are used for moderate to severe pain. They work by binding to opioid receptors in the central nervous system. Adjuvant Analgesics: These include medications like antidepressants and anticonvulsants that are used in conjunction with other analgesics to manage pain, especially of neuropathic origin.
