Introduction
Tradenames: NoDoz, Vivarin.
Indications
- drowsiness, fatigue
- treatment of apnea in infants
- obesity, weight loss ?[7][9]
- neuroprotection in women ?[6]
- may diminish risk of non melanoma skin cancer[9]
- may reduce risk of diabetes mellitus type 2[15][16]
- may reduce risk of stroke in women[17]
- may reduce risk of depression in women[14]
- nasal congestion, sinusitis[20]
- urinary incontinence[20]
- higher caffeine intake associated with reduced cardiovascular risk[25]
- 200-300 mg of caffeine/day may confer 40% reduced cardiometabolic risk[32]
- diminished risk of Parkinson's disease (PD)[26][29]
Dosage
- 100-200 mg PO every 3-4 hours PRN
- maximum: 400 mg/day[12]
- < 500 mg/day considered to be safe[18]
- lethal dose: >= 3 grams within a few hours[18]
Tabs: 100 & 200 mg.
Pharmacokinetics
- metabolized in liver to paraxanthine
- caffeine is a minor metabolite of theophylline
- metabolized by cyt P450 1A2[3]
- maternal metabolism reduced during early pregnancy, clearance is prolonged[8]
- fetal metabolism is low[8]
- high-dose 800 mg in 6 hours increases renal calcium clearance 77%[30]
elimination via liver
1/2life = 3.5 hours
protein binding = 35 %
Adverse effects
- hypertension in adults, adolescents[5]
- moderate use does not increase risk of miscarriage[10]
- high caffeine intake in combination with high stress may be associated with auditory hallucinations[13]
- no association between caffeine intake & cardiovascular events[23]
- no association with arrhythmia (500 mg over 5 hours) in patients with heart failure, even during exercise[24]
- caffeine (>=200 mg/day) during pregnancy associated with overweight offspring up to 5 years of age[27]
- genetic variant in CYP1A2 resulting in slow metabolism of caffeine increases risk of albuminuria, hyperfiltration, & hypertension in heavy coffee consumers (> 3 cups/day)[31]
- toxic effects of caffeine occur with intake > 1.2 grams/day
Drug interactions
- any drug which inhibits cyt P450 1A2 can increase caffeine levels
- any drug which induces cyt P450 1A2 can diminish caffeine levels
- drug interaction(s) of lithium carbonate with xanthine
- drug interaction(s) of MAO inhibitor with caffeine
- drug interaction(s) of methotrexate with caffeine
Laboratory
Mechanism of action
- blocks adenosine A-2A receptors
- relaxes smooth muscle of bronchial airways & pulmonary blood vessels
- in mice, inhibits PP-2A dephosphorylation of threonine 75 on DARPP-32
- may have neuroprotective properties in women[6]
- may have anti-tumor properties[7]
- enhances alertness[19]
- activates arousal[19]
- suppresses the urge to sleep[19]
- may enhance memory consolidation[21]
Notes
- energy drinks may contain significant amounts of caffeine[12]
- FDA recommends avoiding powdered pure caffeine being marketed directly to consumers[23]
