PubChem
| Name: | Caffeine |
|---|---|
| PubChem Compound ID: | 2519 |
| Description: | 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. |

Pharmacology
| Indication: | For management of fatigue, orthostatic hypotension, and for the short term treatment of apnea of prematurity in infants. |
|---|---|
| Pharmacology: |
Caffeine, a naturally occurring xanthine derivative like theobromine and the bronchodilator theophylline, is used as a CNS stimulant, mild diuretic, and respiratory stimulant (in neonates with apnea of prematurity). Often combined with analgesics or with ergot alkaloids, caffeine is used to treat migraine and other headache types. Over the counter,...

| Mechanism of Action: |
Caffeine stimulates medullary, vagal, vasomotor, and respiratory centers, promoting bradycardia, vasoconstriction, and increased respiratory rate. This action was previously believed to be due primarily to increased intracellular cyclic 3′,5′-adenosine monophosphate (cyclic AMP) following inhibition of phosphodiesterase, the enzyme that...

| Absorption: | Readily absorbed after oral or parenteral administration. The peak plasma level for caffeine range from 6-10mg/L and the mean time to reach peak concentration ranged from 30 minutes to 2 hours. |
| Protein binding: | Low (25 to 36%). |
| Biotransformation: | Hepatic cytochrome P450 1A2 (CYP 1A2) is involved in caffeine biotransformation. About 80% of a dose of caffeine is metabolized to paraxanthine (1,7-dimethylxanthine), 10% to theobromine (3,7-dimethylxanthine), and 4% to theophylline (1,3-dimethylxanthine). |
| Route of elimination: | In young infants, the elimination of caffeine is much slower than that in adults due to immature hepatic and/or renal function. |
| Half Life: | 3 to 7 hours in adults, 65 to 130 hours in neonates |
| Toxicity: | LD50=127 mg/kg (orally in mice) |
| Affected organisms: | Humans and other mammals |
