  2. Theobromine - Wikipedia

    en.wikipedia.org/wiki/Theobromine

    The elimination half life of theobromine is between 6 and 8 hours. [1] [2] Unlike caffeine, which is highly water-soluble, theobromine is only slightly water-soluble and is more fat soluble, and thus peaks more slowly in the blood. While caffeine peaks after only 30 minutes, theobromine requires 2–3 hours to peak. [29]

  3. Theobromine poisoning - Wikipedia

    en.wikipedia.org/wiki/Theobromine_poisoning

    Theobromine has a half-life of 10 hours, but over 16% may be unmodified 48 h after a single dose of 10 mg/kg (0.00016 oz/lb) [3] In general, the amount of theobromine found in chocolate is small enough that chocolate can be safely consumed by humans with a negligible risk of poisoning. [4]

  4. Paraxanthine - Wikipedia

    en.wikipedia.org/wiki/Paraxanthine

    Paraxanthine, also known as 1,7-dimethylxanthine, is a metabolite of theophylline and theobromine, two well-known stimulants found in coffee, tea, and chocolate mainly in the form of caffeine. It is a member of the xanthine family of alkaloids , which includes theophylline, theobromine and caffeine .

  5. Biological half-life - Wikipedia

    en.wikipedia.org/wiki/Biological_half-life

    Absorption half-life 1 h, elimination half-life 12 h. Biological half-life (elimination half-life, pharmacological half-life) is the time taken for concentration of a biological substance (such as a medication) to decrease from its maximum concentration (C max) to half of C max in the blood plasma.

  6. Half-life - Wikipedia

    en.wikipedia.org/wiki/Half-life

    Half-life (symbol t ½) is the time required for a quantity (of substance) to reduce to half of its initial value.The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable atoms survive.

  7. Theophylline - Wikipedia

    en.wikipedia.org/wiki/Theophylline

    The elimination half-life varies: 30 hours for premature neonates, 24 hours for neonates, 3.5 hours for children ages 1 to 9, 8 hours for adult non-smokers, 5 hours for adult smokers, 24 hours for those with hepatic impairment, 12 hours for those with congestive heart failure NYHA class I-II, 24 hours for those with congestive heart failure ...

  8. Caffeine - Wikipedia

    en.wikipedia.org/wiki/Caffeine

    Caffeine's biological half-life – the time required for the body to eliminate one-half of a dose – varies widely among individuals according to factors such as pregnancy, other drugs, liver enzyme function level (needed for caffeine metabolism) and age. In healthy adults, caffeine's half-life is between 3 and 7 hours. [5]
