🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Methotrexate inhibits dihydrofolate reductase, preventing the conversion of dihydrofolate to tetrahydrofolate. This leads to decreased synthesis of thymidylate and purines, which are essential for DNA and RNA synthesis. Rapidly dividing cells, such as cancer cells and activated immune cells, are particularly sensitive to this effect. Additionally, methotrexate increases intracellular levels of adenosine, which has anti-inflammatory properties. This dual mechanism explains its use in both cancer and autoimmune diseases.
Mechanism Steps
💡 How to Take biotrexate 1000mg injection
Strength: This product is a 1000 mg injection vial containing methotrexate. It is intended for parenteral administration after appropriate dilution or reconstitution as per the manufacturer's instructions.
Dosage Information
| Adult Dosage | The dose of this medicine varies widely depending on the indication, treatment protocol, and patient factors. For rheumatoid arthritis, typical doses range from 7.5 mg to 25 mg once weekly, given as a single injection. For cancer, doses may range from 30 mg/m² to 12 g/m² depending on the regimen. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function, and response to therapy. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatric oncologist or rheumatologist for individualized dosing. |
| Elderly Dosage | Elderly patients may be more sensitive to the effects of methotrexate, especially bone marrow suppression and renal toxicity. Doses should be adjusted based on renal function and overall health status. Close monitoring is required. |
| Renal Impairment | Methotrexate is primarily excreted by the kidneys. In patients with renal impairment, dose reduction or avoidance is necessary. For mild renal impairment, dose adjustment may be required. For moderate to severe impairment, methotrexate is contraindicated. Consult a nephrologist or clinical pharmacist for guidance. |
| Hepatic Impairment | In patients with hepatic impairment, methotrexate should be used with caution. Dose reduction may be necessary. Regular monitoring of liver function is essential. In severe hepatic impairment, methotrexate is contraindicated. |
| Maximum Daily Dose | The maximum dose varies by indication and protocol. For high-dose cancer therapy, doses up to 12 g/m² have been used. For rheumatoid arthritis, the maximum recommended weekly dose is typically 25 mg. Dose must be individualized by a qualified clinician. |
