What is anelgesic?

Definition

An analgesic is a drug or other agent that relieves pain. Analgesics are used to treat a wide variety of pain conditions, including headaches, muscle pain, arthritis, and cancer pain.

How Do Analgesics Work?

Analgesics work by either blocking the transmission of pain signals from the nerves to the brain or by altering the way the brain perceives pain. There are two main types of analgesics:

* Non-opioid analgesics: These drugs, which include aspirin, ibuprofen, and naproxen, relieve pain by blocking the production of prostaglandins, which are chemicals that are involved in the inflammation process.

* Opioid analgesics: These drugs, which include morphine, codeine, and oxycodone, bind to opioid receptors in the brain and spinal cord, which blocks the transmission of pain signals to the brain.
