  2. Equianalgesic - Wikipedia

    en.wikipedia.org/wiki/Equianalgesic

    An equianalgesic chart is a conversion chart that lists equivalent doses of analgesics (drugs used to relieve pain). Equianalgesic charts are used for calculation of an equivalent dose (a dose which would offer an equal amount of analgesia) between different analgesics. [1]

  3. Median lethal dose - Wikipedia

    en.wikipedia.org/wiki/Median_lethal_dose

    In toxicology, the median lethal dose, LD 50 (abbreviation for "lethal dose, 50%"), LC 50 (lethal concentration, 50%) or LCt 50 is a toxic unit that measures the lethal dose of a given substance. [1] The value of LD 50 for a substance is the dose required to kill half the members of a tested population after a specified test duration.

  4. Extended-release morphine - Wikipedia

    en.wikipedia.org/wiki/Extended-release_morphine

    Extended-release (or slow-release) formulations of morphine are those whose effect last substantially longer than bare morphine, availing for, e.g., one administration per day. Conversion between extended-release and immediate-release (or "regular") morphine is easier than conversion to or from an equianalgesic dose of another opioid with ...

  5. Patient-controlled analgesia - Wikipedia

    en.wikipedia.org/wiki/Patient-controlled_analgesia

    Narcotics are the most common analgesics administered through IV PCAs. [6] [7] It is important for caregivers to monitor patients for the first two to twenty-four hours to ensure they are using the device properly. [8] With an IV PCA the patient is protected from overdose by the caregiver programming the PCA to deliver a dose at frequent set ...

  6. Morphine - Wikipedia

    en.wikipedia.org/wiki/Morphine

    In the Netherlands, morphine is classified as a List 1 drug under the Opium Law. In New Zealand, morphine is classified as a Class B drug under the Misuse of Drugs Act 1975. [153] In the United Kingdom, morphine is listed as a Class A drug under the Misuse of Drugs Act 1971 and a Schedule 2 Controlled Drug under the Misuse of Drugs Regulations ...

  7. Route of administration - Wikipedia

    en.wikipedia.org/wiki/Route_of_administration

    Drug administration via the nasal cavity yields rapid drug absorption and therapeutic effects. [33] This is because drug absorption through the nasal passages does not go through the gut before entering capillaries situated at tissue cells and then systemic circulation and such absorption route allows transport of drugs into the central nervous ...

  8. Pharmacokinetics - Wikipedia

    en.wikipedia.org/wiki/Pharmacokinetics

    The model outputs for a drug can be used in industry (for example, in calculating bioequivalence when designing generic drugs) or in the clinical application of pharmacokinetic concepts. Clinical pharmacokinetics provides many performance guidelines for effective and efficient use of drugs for human-health professionals and in veterinary medicine .

  9. Instrumental variables estimation - Wikipedia

    en.wikipedia.org/wiki/Instrumental_variables...

    One computational method which can be used to calculate IV estimates is two-stage least squares (2SLS or TSLS). In the first stage, each explanatory variable that is an endogenous covariate in the equation of interest is regressed on all of the exogenous variables in the model, including both exogenous covariates in the equation of interest and ...
