Short-term effect of coffee on blood fibrinolytic activity in healthy adults. 1977

W A Samarrae, and A S Truswell

Ingestion of coffee was followed after one-half and one hour by shortening of whole blood fibrinolysis time. The amount of coffee was equivalent to a heaped teaspoonsful and a standard brand of instant coffee was tested. The effect was laregly lost when decaffeinated coffee was taken. It appears that the caffeine in the amounts of coffee ordinarily consumed stimulates fibrinolytic activity but 2 of the 12 subjects were resistant to the effect.

D002110 Caffeine A methylxanthine naturally occurring in some beverages and also used as a pharmacological agent. Caffeine's most notable pharmacological effect is as a central nervous system stimulant, increasing alertness and producing agitation. It also relaxes SMOOTH MUSCLE, stimulates CARDIAC MUSCLE, stimulates DIURESIS, and appears to be 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. 1,3,7-Trimethylxanthine,Caffedrine,Coffeinum N,Coffeinum Purrum,Dexitac,Durvitan,No Doz,Percoffedrinol N,Percutaféine,Quick-Pep,Vivarin,Quick Pep,QuickPep
