Dermatologic Therapy, 2007
Methotrexate is a folic acid analog pioneered for use in inflammatory diseases by dermatologists, and used successfully for over 40 years for a wide variety of cutaneous diseases. In addition to its antiproliferative properties, methotrexate has other more recently recognized anti-inflammatory properties related to its effects on adenosine.

INTRODUCTION Methotrexate is an anatlogue of aminopterin which was first used in the treatment of acute leukaemia in 1947. However, because of its better therapeutic index, the closely related amethopterin superseded aminopterin and was marketed as Methotrexate.

The pharmacology of methotrexate
Journal of the American Academy of Dermatology, 1991Methotrexate is a useful antimetabolite for the treatment of both benign and malignant proliferative disorders. When the pharmacokinetics and potential toxicity of this drug are understood, treatment regimens can be tailored to the underlying kinetics of the target population.

Clinical and experimental rheumatology, 2010
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 ...

The pharmacology of methotrexate
Expert Opinion on Pharmacotherapy, 2001Ectopic pregnancy (EP) is a major cause of maternal morbidity and mortality. The treatment of this condition is primarily surgical, but medical management in selected cases is safe, effective, cost-effective and eliminates the morbidity of surgery.

Journal of Medicinal Chemistry, 1979
Analogues of methotrexate (MTX) were prepared by alkylation of side-chain precursors with 6-(bromomethyl)-2,4-pteridinediamine followed, where necessary, by saponification of the intermediate esters and, in two cases, by electrophilic substitution reactions in the pyridine ring portion of 3-deazamethotrexate.

Methotrexate for the neurologist
Practical NeurologyThe use of methotrexate in clinical practice has expanded significantly in recent years, as an effective chemotherapeutic agent as well as disease-modifying treatment for conditions such as rheumatoid arthritis, psoriasis and Crohn’s disease. It is also used as a steroid-sparing agent for a range of inflammatory diseases of the central and peripheral ...

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.

Pharmacokinetics of methotrexate
Clinical Pharmacology & Therapeutics, 1974Methotrexate (Mtx) is a competitive inhibitor of the enzymatic activity of dihydrofolate reductase, decreasing the reduction of folic acid to tetrahydrofolate and thereby the activity of thymi dilate kinase. The net effect is a decrease in biosynthesis of deoxyribonucleic acid (DNA) primarily, but also of ribonucleic acid (RNA) and protein. Whereas the
