D001826	Body Fluids	Liquid components of living organisms.	Body Fluid,Fluid, Body,Fluids, Body
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

D013806	Theophylline	A methyl xanthine derivative from tea with diuretic, smooth muscle relaxant, bronchial dilation, cardiac and central nervous system stimulant activities. Theophylline inhibits the 3',5'-CYCLIC NUCLEOTIDE PHOSPHODIESTERASE that degrades CYCLIC AMP thus potentiates the actions of agents that act through ADENYLYL CYCLASES and cyclic AMP.	1,3-Dimethylxanthine,3,7-Dihydro-1,3-dimethyl-1H-purine-2,6-dione,Accurbron,Aerobin,Aerolate,Afonilum Retard,Aquaphyllin,Armophylline,Bronchoparat,Bronkodyl,Constant-T,Elixophyllin,Euphylong,Glycine Theophyllinate,Lodrane,Monospan,Nuelin,Nuelin S.A.,Quibron T-SR,Slo-Phyllin,Somophyllin-T,Sustaire,Synophylate,Theo Von Ct,Theo-24,Theo-Dur,Theobid,Theocin,Theoconfin Continuous,Theodur,Theolair,Theolix,Theon,Theonite,Theopek,Theophylline Anhydrous,Theophylline Sodium Glycinate,Theospan,Theostat,Theovent,Uniphyl,Uniphyllin,Uniphylline,1,3 Dimethylxanthine,Anhydrous, Theophylline,Constant T,ConstantT,Ct, Theo Von,Glycinate, Theophylline Sodium,Quibron T SR,Quibron TSR,Slo Phyllin,SloPhyllin,Sodium Glycinate, Theophylline,Somophyllin T,SomophyllinT,Theo 24,Theo Dur,Theo24,Theophyllinate, Glycine,Von Ct, Theo
D014527	Uric Acid	An oxidation product, via XANTHINE OXIDASE, of oxypurines such as XANTHINE and HYPOXANTHINE. It is the final oxidation product of purine catabolism in humans and primates, whereas in most other mammals URATE OXIDASE further oxidizes it to ALLANTOIN.	2,6,8-Trihydroxypurine,Ammonium Acid Urate,Monosodium Urate,Monosodium Urate Monohydrate,Potassium Urate,Sodium Acid Urate,Sodium Acid Urate Monohydrate,Sodium Urate,Sodium Urate Monohydrate,Trioxopurine,Urate,Acid Urate, Ammonium,Acid Urate, Sodium,Acid, Uric,Monohydrate, Monosodium Urate,Monohydrate, Sodium Urate,Urate Monohydrate, Monosodium,Urate Monohydrate, Sodium,Urate, Ammonium Acid,Urate, Monosodium,Urate, Potassium,Urate, Sodium,Urate, Sodium Acid
D014556	Urine	Liquid by-product of excretion produced in the kidneys, temporarily stored in the bladder until discharge through the URETHRA.
