[100], "Caffeine addiction" was added to the ICDM-9 and ICD-10. [1][3][5] Tolerance to the autonomic effects of increased blood pressure and heart rate, and increased urine output, develops with chronic use (i.e., these symptoms become less pronounced or do not occur following consistent use).[20]. [149] As a competitive nonselective phosphodiesterase inhibitor,[150] caffeine raises intracellular cAMP, activates protein kinase A, inhibits TNF-alpha[151][152] and leukotriene[153] synthesis, and reduces inflammation and innate immunity.

With a continued wakeful state, over time adenosine accumulates in the neuronal synapse, in turn binding to and activating adenosine receptors found on certain CNS neurons; when activated, these receptors produce a cellular response that ultimately increases drowsiness. [50] Caffeine consumption before constant load exercise is associated with reduced perceived exertion. The earliest evidence of cocoa bean use comes from residue found in an ancient Mayan pot dated to 600 BCE. When caffeine is consumed, it antagonizes adenosine receptors; in other words, caffeine prevents adenosine from activating the receptor by blocking the location on the receptor where adenosine binds to it.

[142], In addition to its activity at adenosine receptors, caffeine is an inositol trisphosphate receptor 1 antagonist and a voltage-independent activator of the ryanodine receptors (RYR1, RYR2, and RYR3). [131] When alcohol and caffeine are consumed jointly, the effects produced by caffeine are affected, but the alcohol effects remain the same.
