Answer #1

Ans) Fever can be defined as any elevation of body temperature above the normal level.

- The mechanism of fever appears to be a defensive reaction by the body against infectious disease. When bacteria or viruses invade the body and cause tissue injury, one of the immune system's responses is to produce pyrogens.

Antipyretic is medication used to lower body temperature when a fever is present. Examples: Aspirin, acetaminophen/paracetamol (Tylenol), ibuprofen, and others.

Pharmacology:

- Antipyretics cause the hypothalamus to override a prostaglandin-induced increase in temperature.

- The body then works to lower the temperature, which results in a reduction in fever.

- Most antipyretic medications have other purposes.
