Part Descriptions
LP16057-9 Caffeine
Caffeine is methylxanthine naturally occurring in some beverages such as coffee, and is also a pharmacological agent. Caffeine is a central nervous system stimulant, that increases alertness and produces agitation. It also relaxes smooth muscle, stimulates cardiac muscle, stimulates diuresis, and is useful in the treatment of some types of headache. Several cellular actions of caffeine have been observed, but it is not entirely clear how each contributes to its pharmacological profile. Among the most important are inhibition of cyclic nucleotide phosphodiesterases, antagonism of adenosine receptors, and modulation of intracellular calcium handling.

- Change Reason
- The Property has been changed from ACnc to reflect the new model for ordinal terms where results are based on a cut-off value.; The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
