Dose Mode Days Rituximab: 375 mg/m 2: IV infusion: Day 1 Ifosfamide: 5000 mg/m 2: IV continuous infusion over 24 hours: Day 2 Mesna for haemorrhagic cystitis prophylaxis with ifosfamide: 5000 mg/m 2: IV continuous infusion over 24 hours: Day 2 Carboplatin: Optimized to get AUC = 5 (max. 800 mg) IV infusion: Day 2 Etoposide: 100 mg/m 2: IV ...
Rituximab, sold under the brand name Rituxan among others, is a monoclonal antibody medication used to treat certain autoimmune diseases and types of cancer. [18] It is used for non-Hodgkin lymphoma, chronic lymphocytic leukemia (in children and adults, but not recommended in elderly patients), rheumatoid arthritis, granulomatosis with polyangiitis, idiopathic thrombocytopenic purpura ...
There are various competing calculation methods for the drug accumulation ratio, yielding somewhat different results. A commonly used formula defines R ac as the ratio of the area under the curve (AUC) during a single dosing interval under steady state conditions to the AUC during a dosing interval after one single dose: [1]
For example, gentamicin is an antibiotic that can be nephrotoxic (kidney damaging) and ototoxic (hearing damaging); measurement of gentamicin through concentrations in a patient's plasma and calculation of the AUC is used to guide the dosage of this drug. [3] AUC becomes useful for knowing the average concentration over a time interval, AUC/t.
The IC 50 of a drug can be determined by constructing a dose-response curve and examining the effect of different concentrations of antagonist on reversing agonist activity. IC 50 values can be calculated for a given antagonist by determining the concentration needed to inhibit half of the maximum biological response of the agonist. [ 4 ]
The sitcom sensation underwent 12 rounds of weekly chemotherapy, followed by three weeks of radiation, She now continues to be treated with infusions of Herceptin and a daily dose of Tamoxifen.
Therefore the dose required to give a certain plasma concentration can be determined if the V D for that drug is known. The V D is not a real volume; it is more a reflection of how a drug will distribute throughout the body depending on several physicochemical properties, e.g. solubility, charge, size, etc.
The solution of this differential equation is useful in calculating the concentration after the administration of a single dose of drug via IV bolus injection: = C t is concentration after time t; C 0 is the initial concentration (t=0) K is the elimination rate constant
