The clinical relevance of the concept of bioavailability rests on two main principles. First, that measurement of the active component at the site of action is generally not possible and, secondly, that a relationship exists between on the one hand efficacy and/or safety and on the other hand concentration of the active compound or its active ...

Pharmacokinetics of Methotrexate and 7-Hydroxy-Methotrexate After Methotrexate Infusions
Cancer Drug Delivery, 1987Methotrexate was administered by IV infusion, 2g (1.19 +/- 0.05 g/m2) over 24 hours, to a homogeneous group of patients undergoing treatment for breast cancer. Three courses were given at three week intervals. Methotrexate and 7-hydroxy-methotrexate plasma and urine pharmacokinetics were investigated. The average terminal half-lives of methotrexate and

Expert Review of Clinical Pharmacology
Methotrexate polyglutamates (MTXPGs) are intracellular metabolites of methotrexate (MTX) that play a critical role in the drug's activity, influencing both its efficacy and toxicity. As the exact implications of MTXPGs in these processes remain a subject of debate, a comprehensive review of MTXPGs could provide valuable insights for clinicians and ...

Rheumatic Disease Clinics of North America, 1997
Hepatoxicity is a major adverse reaction that can occur during methotrexate treatment of the rheumatic diseases. The pathologic lesions are nonspecific and the pathogenesis is poorly understood. Early studies in psoriasis clearly established a relationship between hepatic injury and several risk factors, particularly alcohol use.

Scandinavian Journal of Rheumatology, 1996
Methotrexate (MTX) has become one of the most widely prescribed second-line agents world-wide for rheumatoid arthritis (RA). Studies have established efficacy in populations which have failed other second-line agents. Although MTX must be considered as a potential hepatotoxin, studies have shown that liver histologic changes can be predicted by ...
