Opioid analgesics are a class of medications used to relieve pain. They work by binding to specific receptors in the brain and spinal cord, reducing the perception of pain. Common examples include morphine, oxycodone, and hydrocodone. These medications are often prescribed for moderate to severe pain, such as that experienced after surgery or due to chronic conditions. While effective for pain management, opioid analgesics carry risks, including the potential for addiction and overdose. Due to these risks, healthcare providers typically prescribe them with caution and may recommend alternative pain management strategies, such as non-opioid medications or physical therapy.
