Codeine is a medication that falls under the category of opioid analgesics, commonly used to provide relief from pain and suppress cough. It is derived from opium and has been used for centuries to treat various ailments.
Codeine works by binding to specific receptors in the brain, spinal cord, and other parts of the body to reduce the perception of pain. It also acts on the brain's cough center, reducing the urge to cough. Due to its analgesic and cough suppressant properties, codeine is often found in combination with other drugs in prescription and over-the-counter medications.
