Methotrexate, a folic acid analog, is a long-standing treatment for inflammatory skin diseases. New research explores its anti-inflammatory effects and genetic factors to optimize therapy and predict side effects.
Area of Science:
- Dermatology
- Pharmacology
- Immunology
Background:
- Methotrexate is a folic acid analog with over 40 years of use in dermatology for cutaneous diseases.
- It possesses antiproliferative and anti-inflammatory properties, the latter linked to adenosine pathways.
Purpose of the Study:
- To review methotrexate's pharmacokinetics, administration, dosing, side effects, and interactions.
- To provide practical guidelines for methotrexate therapy initiation and adjustment.
- To summarize emerging research on its mechanism of action and future therapeutic potential.
Main Methods:
- Literature review of existing studies on methotrexate.
- Analysis of pharmacokinetic and pharmacodynamic data.
- Synthesis of current research on mechanisms and genetic variations.
Main Results:
- Established efficacy and safety profile of methotrexate in various dermatological conditions.
- Identified anti-inflammatory mechanisms beyond antiproliferation, involving adenosine.
- Highlighted the role of genetic variations in predicting treatment response and adverse events.
Conclusions:
- Methotrexate remains a cornerstone therapy for numerous skin diseases.
- Understanding its adenosine-related anti-inflammatory effects and genetic factors can personalize treatment.
- Further research promises optimized methotrexate therapy and improved patient outcomes.

Phase II Reactions: Methylation Reactions
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...
