Osmosis video - Analgesics: Nursing pharmacology

Analgesics are drugs that reduce pain. They work by either blocking the transmission of pain signals or by reducing inflammation. There are many different types of analgesics available, and they can be divided into two main groups: Non-opioid analgesic agents which include non-steroidal anti-inflammatory drugs (NSAIDs); and opioid analgesics.

NSAIDs include ibuprofen, aspirin, and naproxen. These drugs work by blocking the action of cyclooxygenase (COX), an enzyme that is involved in the production of inflammatory mediators. Opioid analgesics include morphine, codeine, and fentanyl. These drugs work by binding to opioid receptors in the brain, which reduces the perception of pain.
