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.

LP16057-9   Caffeine
Because preterm babies metabolilze theophylline to caffeine, baselline levels of caffeine should be measured in infants treated with theophylline. Baseline levels should also be performed in infants whose mother consumed caffeine prior to delivery. Source: National Library of Medicine, Caffeine

LP20176-1   trough
In medicine, a trough level is the lowest level that a medicine is present in the body. In a medicine that is administered periodically, the trough level should be measured just before the administration of the next dose in order to avoid overdosing. It should be contrasted with a "peak level", which is the highest level of the medicine in the body, and the "average level", which is the mean level over time. It helps in therapeutic drug monitoring. It is widely used in clinical trials for newer medicines for its therapeutic effectiveness and safety.
