Caffeine is an addictive psychoactive compound, consumed mostly in the form of brewed coffee, instant coffee, tea and caffeinated soft drinks. Caffeine is reported to be an allergen and causes anaphylaxis. It is added to common analgesics such as paracetamol, ibuprofen and aspirin for enhancing their analgesic efficacy. It is a plant-derived drug and has been detected in low doses in the floral nectar and pollen of Citrus. Determination of caffeine in beverages by square-wave voltammetry using Nafion-ruthenium oxide pyrochlore chemically modified electrode has been reported. Caffeine acts as an antagonist of adenosine A1 receptors (A1R) and A2AR at non-toxic doses. Chronic consumption of caffeine is reported to prevent the memory impairment in type 2 diabetic mice.
Caffeine (1,3,7-Trimethylxanthine) has been used in a study to determine the benefits of co-ingestion of carbohydrate and caffeine on rugby performance.
Caffeine is the suitable reagent used to investigate effect of its exposure during embryogenesis.

A central nervous system stimulant believed to act through adenosine receptors and monoamine neurotransmitters. It is an adenosine receptor antagonist and adenosine 3′,5′-cyclic monophosphate (cAMP) phosphodiesterase inhibitor. Thus, levels of cAMP increase in cells following treatment with caffeine. It has been reported to affect cellular calcium levels, releasing calcium from intracellular stores. It overrides the cell cycle effects of various chemicals such as protease inhibitors, preventing apoptosis; and it has been shown to inhibit cellular DNA repair mechanisms.
