Which medication is used as an antipyretic?

Antipyretics are medications that are specifically used to reduce fever. All three medications listed—ibuprofen, aspirin, and acetaminophen—have properties that allow them to lower body temperature when fever is present.

Ibuprofen belongs to the class of nonsteroidal anti-inflammatory drugs (NSAIDs), which work by inhibiting the production of prostaglandins, chemicals in the body that promote inflammation and raise fever.

Aspirin, another NSAID, functions similarly by reducing the production of prostaglandins, thereby having both analgesic (pain-relieving) and antipyretic effects.

Acetaminophen, although not classified as an NSAID, is also effective as an antipyretic. It works in a slightly different manner by acting on the hypothalamic heat-regulating center, promoting heat loss and reducing fever.

Since all three medications can effectively reduce fever, they all qualify as antipyretics, making the correct answer that all of the mentioned medications are capable of serving this purpose.
