  2. Biological half-life - Wikipedia

    en.wikipedia.org/wiki/Biological_half-life

    Caesium in the body has a biological half-life of about one to four months. Mercury (as methylmercury) in the body has a half-life of about 65 days. Lead in the blood has a half life of 28–36 days. [29] [30] Lead in bone has a biological half-life of about ten years. Cadmium in bone has a biological half-life of about 30 years.

  3. List of benzodiazepines - Wikipedia

    en.wikipedia.org/wiki/List_of_benzodiazepines

    The tables below contain a sample list of benzodiazepines and benzodiazepine analogs that are commonly prescribed, with their basic pharmacological characteristics, such as half-life and equivalent doses to other benzodiazepines, also listed, along with their trade names and primary uses.

  4. Benzodiazepine - Wikipedia

    en.wikipedia.org/wiki/Benzodiazepine

    Desmethyldiazepam has a half-life of 36–200 hours, and flurazepam, with the main active metabolite of desalkylflurazepam, with a half-life of 40–250 hours. These long-acting metabolites are partial agonists. [6] [145] Short-acting compounds have a median half-life of 1–12 hours.

  5. Triazolam - Wikipedia

    en.wikipedia.org/wiki/Triazolam

    Triazolam is short-acting, is lipophilic, and is metabolized hepatically via oxidative pathways. Triazolam produces one short-acting active metabolite, alpha-hydroxytriazolam, which is suspected to be of minor clinical significance. [31] The half-life of triazolam is only 2 hours making it a very short acting benzodiazepine drug. [32]

    Radioactive isotope table "lists ALL radioactive nuclei with a half-life greater than 1000 years", incorporated in the list above. The NUBASE2020 evaluation of nuclear physics properties F.G. Kondev et al. 2021 Chinese Phys. C 45 030001. The PDF of this article lists the half-lives of all known radioactives nuclides.

  7. Half-life - Wikipedia

    en.wikipedia.org/wiki/Half-life

    For example, the medical sciences refer to the biological half-life of drugs and other chemicals in the human body. The converse of half-life (in exponential growth) is doubling time. The original term, half-life period, dating to Ernest Rutherford's discovery of the principle in 1907, was shortened to half-life in the early 1950s. [1]

  8. Equianalgesic - Wikipedia

    en.wikipedia.org/wiki/Equianalgesic

    An equianalgesic chart can be a useful tool, but the user must take care to correct for all relevant variables such as route of administration, cross tolerance, half-life and the bioavailability of a drug. [5] For example, the narcotic levorphanol is 4–8 times stronger than morphine, but also has a much longer half-life. Simply switching the ...

  9. Temazepam - Wikipedia

    en.wikipedia.org/wiki/Temazepam

    The unchanged drug was 96% bound to plasma proteins. The blood-level decline of the parent drug was biphasic, with the short half-life ranging from 0.4 to 0.6 hours and the terminal half-life from 3.5 to 18.4 hours (mean 8.8 hours), depending on the study population and method of determination.
