Summary
Methotrexate (MTX) is a key drug for rheumatoid arthritis (RA). Current evidence indicates it is safe to continue MTX around elective surgeries, improving disease control.
Area of Science:
- Rheumatology
- Pharmacology
- Surgical Science
Background:
- Methotrexate (MTX) is the primary disease-modifying antirheumatic drug for rheumatoid arthritis (RA).
- Patients with RA frequently require elective surgical procedures.
- Uncertainty exists regarding the perioperative management of MTX in RA patients.
Purpose of the Study:
- To evaluate the safety and efficacy of continuing Methotrexate (MTX) during the perioperative period for patients with rheumatoid arthritis (RA).
- To clarify current recommendations for MTX use in patients undergoing elective surgery.
Main Methods:
- Review of current literature and available data on MTX use in the perioperative setting.
- Analysis of evidence regarding the impact of MTX interruption versus continuation on disease activity and surgical outcomes.
Main Results:
- Available data do not support the routine discontinuation of MTX for elective surgery.
- Evidence suggests that continuing MTX perioperatively is safe for RA patients.
- Interrupting weekly MTX administration may lead to poorer disease control.
Conclusions:
- Methotrexate (MTX) does not need to be discontinued for elective surgical procedures in patients with rheumatoid arthritis (RA).
- Continuing MTX perioperatively is safe and beneficial for maintaining disease control in RA patients.
- Clinicians should consider the evidence supporting uninterrupted MTX therapy around surgery.

Therapeutic Drug Monitoring: Affecting Factors
Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.
Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel Disease...
Phase II Reactions: Methylation Reactions
Methylation is a phase II biotransformation process involving the attachment of a methyl group to a substrate. Enzymes known as methyltransferases orchestrate this reaction.
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...

Parenteral Anesthetics: Overview
Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.
