Voriconazole, sold under the brand name Vfend among others, is an antifungal medication used to treat a number of fungal infections. [5] This includes aspergillosis , candidiasis , coccidioidomycosis , histoplasmosis , penicilliosis , and infections by Scedosporium or Fusarium . [ 5 ]
3) Regarding dosage adjustment to recommend, this TDM result suggests that a doubled dose of 800 mg daily might be suitable to drive the concentration curve close to target (blue dotted line). Note that this interpretation assumes that the patient's adherence to prescription is good, and that the sample measurement is accurate.
Drug titration is the process of adjusting the dose of a medication for the maximum benefit without adverse effects. [ 1 ] When a drug has a narrow therapeutic index , titration is especially important, because the range between the dose at which a drug is effective and the dose at which side effects occur is small. [ 2 ]
Dosage typically includes information on the number of doses, intervals between administrations, and the overall treatment period. [3] For example, a dosage might be described as "200 mg twice daily for two weeks," where 200 mg represents the individual dose, twice daily indicates the frequency, and two weeks specifies the duration of treatment.
Some antibiotics are actively eliminated through the kidneys. Impaired renal function will require reduction of the drug dose to avoid excessively elevated plasma drug concentrations that could lead to toxicity. [17] Dose adjustment can be done by reducing the amount administered in each dose or by increasing the interval between doses. [17]
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.
Caspofungin has some interference with ciclosporin metabolism, and micafungin has some interference with sirolimus (rapamycin), but anidulafungin needs no dose adjustments when given with ciclosporin, tacrolimus, or voriconazole. [21]
Repeated administration of a medication is also different from single dosing, as many drugs have active metabolites that can build up in the body. [6] Patient variables such as sex, age, and organ function may also influence the effect of the drug on the system. These variables are rarely included in equianalgesic charts. [7] [3] [8]
