Antipyretics

  • Antipyretics from the Greek anti, against, and pyreticus, (pertaining to fever) are drugs or herbs that reduce fever.
  • Normally, they will not lower body temperature if one does not have a fever.
  • Antipyretics cause the hypothalamus to override an interleukin-induced increase in temperature. The body then works to lower the temperature, result in a reduction in fever.
  • Most antipyretic medications have other purposes.
  • The most common antipyretics in the United States are Antipyretics and aspirin, which are used primarily as pain relievers.
  • Non-steroidal anti-inflammatory drugs (NSAIDs) are antipyretic, anti-inflammatory, and pain relievers.
  • There is some debate over the appropriate use of such medications, as fever is part of the body's immune response to infection.

Taurine

  • Taurine is a non-protein, non-essential amino acid which functions as a calmer of the central nervous system due to its inhibitory action.
  • Taurine is the second most abundant amino acid in muscle tissue, with glutamine being the first.
  • But it's not actually part of the muscle tissue. Rather, it's primarily in the amino acid pool within each muscle cell and is, in fact, not even a component of protein but remains free in our bodies.
  • It does, however, act as the building block of other amino acids.
  • Many experts consider taurine conditionally essential because intense exercise as well as other types of stress deplete the nutrient.
