Application

Caffeine has been used:
  • to functionally disable Ca2+ removal via sarco/endoplasmic reticulum Ca2+ ATPase (SERCA)[1]
  • to determine its effects in overcoming excitation-contraction-coupling failure[2]
  • to compare its role as a stimulant with guarana[3]

General description

Caffeine is a commonly consumed pharmacologically active substance. It is a member of the class of methylxanthines.[4] It is a natural alkaloid found in coffee, cocoa and other plants. Caffeine might be linked to osteoporosis, cardiovascular risk, arrhythmia and gastrointestinal disturbances.[5] Caffeine is used to treat orthostatic hypotension,[6] bronchopulmonary dysplasia and apnea of prematurity (AOP).[7]
