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 ...
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.
The therapeutic index (TI; also referred to as therapeutic ratio) is a quantitative measurement of the relative safety of a drug with regard to risk of overdose.It is a comparison of the amount of a therapeutic agent that causes toxicity to the amount that causes the therapeutic effect. [1]
A loading dose is most useful for drugs that are eliminated from the body relatively slowly, i.e. have a long systemic half-life. Such drugs need only a low maintenance dose in order to keep the amount of the drug in the body at the appropriate therapeutic level , but this also means that, without an initial higher dose, it would take a long ...
It is a promising treatment of renal diseases with proteinuria, in particular patients with resistance or partial response to rituximab. [10] A single low-dose infusion of Obinutuzumab, found to be effective and safe in inducing prolonged remission in children with steroid-dependent or frequently relapsing nephrotic syndrome.
The formula for determining the dose is: [1] If there is a single recommended maintenance dose in the literature, this is preferred. If there are a range of recommended maintenance doses then If the literature recommends generally increasing from initial to maximum dose provided it is tolerated, pick the maximum dose.
Whilst equivalent dose is used for the stochastic effects of external radiation, a similar approach is used for internal, or committed dose. The ICRP defines an equivalent dose quantity for individual committed dose, which is used to measure the effect of inhaled or ingested radioactive materials.
8. Was the reaction more severe when the dose was increased, or less severe when the dose was decreased? Yes (+1) No (0) Do not know or not done (0) 9. Did the patient have a similar reaction to the same or similar drugs in any previous exposure? Yes (+1) No (0) Do not know or not done (0) 10. Was the adverse event confirmed by any objective ...
