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]
In 1997, ondansetron was the subject of a meta-analysis case study. Researchers examined 84 trials, with 11,980 people receiving ondansetron, published between 1991 and September 1996. Intravenous ondansetron 4 mg versus placebo was investigated in 16 reports and three further reports which had been duplicated a total of six times.
Serotonin (5-HT3) receptor antagonists can be administered as a single dose at the end of surgery. Adverse effects include prolongation of the QT interval on electrocardiogram (EKG). Medications include ondansetron, granisetron, and dolasetron. Anticholinergics can be used as a long-acting patch placed behind the patient's ear. Adverse effects ...
Ondansetron (Zofran) is administered in an oral tablet form, orally dissolving tablet form, orally dissolving film, sublingual, or in an IV/IM injection. Tropisetron (Setrovel, Navoban) can be administered in oral capsules or in injection form. Palonosetron (Aloxi) can be administered in an injection or in oral capsules.
A V D greater than the total volume of body water (approximately 42 liters in humans [5]) is possible, and would indicate that the drug is highly distributed into tissue. In other words, the volume of distribution is smaller in the drug staying in the plasma than that of a drug that is widely distributed in tissues. [6]
In pharmacokinetics, a maintenance dose is the maintenance rate [mg/h] of drug administration equal to the rate of elimination at steady state. This is not to be confused with dose regimen , which is a type of drug therapy in which the dose [mg] of a drug is given at a regular dosing interval on a repetitive basis.
Absolute bioavailability refers to the bioavailability of a drug when administered via an extravascular dosage form (i.e. oral tablet, suppository, subcutaneous, etc.) compared with the bioavailability of the same drug administered intravenously (IV). This is done by comparing the AUC of the non-intravenous dosage form with the AUC for the drug ...
To ensure that the drug taker who has poor absorption is dosed appropriately, the bottom value of the deviation range is employed to represent real bioavailability and to calculate the drug dose needed for the drug taker to achieve systemic concentrations similar to the intravenous formulation. [4] To dose without knowing the drug taker's ...
