For comparison, those with a V d L/kg body weight of less than 0.2 are mainly distributed in blood plasma, 0.2-0.7 mostly in the extracellular fluid and those with more than 0.7 are distributed throughout total body water.
The toxic dose of paracetamol is highly variable. In general the recommended maximum daily dose for healthy adults is 4 grams. [17] [18] Higher doses lead to increasing risk of toxicity. In adults, single doses above 10 grams or 200 mg/kg of bodyweight, whichever is lower, have a reasonable likelihood of causing toxicity.
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]
Paracetamol's bioavailability is dose-dependent: it increases from 63 % for 500 mg dose to 89 % for 1000 mg dose. [6] Its plasma terminal elimination half-life is 1.9–2.5 hours, [ 6 ] and volume of distribution is roughly 50 L. [ 132 ] Protein binding is negligible, except under the conditions of overdose, when it may reach 15–21 %. [ 6 ]
Threshold dose is the minimum dose of drug that triggers minimal detectable biological effect in an animal. [1] At extremely low doses, biological responses are absent for some of the drugs. The increase in dose above threshold dose induces an increase in the percentage of biological responses. [ 2 ]
As many drivers make their way home from Thanksgiving travels, most of the north and eastern U.S. will face below-normal temperatures over the next week – with many regions currently under ...
An analgesic drug, also called simply an analgesic, antalgic, pain reliever, or painkiller, is any member of the group of drugs used for pain management.Analgesics are conceptually distinct from anesthetics, which temporarily reduce, and in some instances eliminate, sensation, although analgesia and anesthesia are neurophysiologically overlapping and thus various drugs have both analgesic and ...
the dose at which toxicity occurs in 50% of cases. LD Lethal Dose the dose at which death occurs in 50% of cases. [6]: 73 [7] [8] TI Therapeutic Index a quantitative measurement of the relative safety of a drug by comparison of the amount of a therapeutic agent that causes toxicity to the amount that causes the therapeutic effect [1]
