antipyretic

n. a drug that helps control fever or other forms of hyperthermia (raised body temperature) by acting on the thermoregulatory center in the hypothalamus. Antipyretics may also help the body to dissipate heat faster by dilating peripheral arteries. Aspirin and other nonopioid analgesics function as antipyretics.
