🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Methotrexate inhibits the enzyme dihydrofolate reductase (DHFR), which converts dihydrofolate to tetrahydrofolate. Tetrahydrofolate is required for the synthesis of thymidylate and purines, which are building blocks of DNA and RNA. By blocking this pathway, methotrexate prevents cell division and slows the growth of rapidly dividing cells such as cancer cells and activated immune cells. In autoimmune diseases, it also reduces the production of inflammatory cytokines and promotes the release of adenosine, which has anti-inflammatory effects.
Mechanism Steps
💡 How to Take Trexova 50mg Injection
Strength: Injection: 50 mg/2 mL (25 mg/mL) in a single-use vial.
Dosage Information
| Adult Dosage | The dosage of this medicine is highly individualized and depends on the specific condition being treated, the patient's response, and other factors. For rheumatoid arthritis, a common regimen is 7.5 to 20 mg once weekly, either as a single dose or divided into three doses over 24 hours. For psoriasis, similar weekly doses are used. For cancer, doses can range from 30 to 500 mg/m² or more, given at varying intervals. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. |
| Elderly Dosage | Elderly patients may be more sensitive to the effects of methotrexate, especially bone marrow suppression and liver toxicity. Doses should be adjusted based on renal function and overall health. Close monitoring is required. |
| Renal Impairment | Dose reduction is required in patients with renal impairment. Methotrexate is contraindicated in severe renal impairment. For moderate impairment, doses should be reduced and monitored closely. |
| Hepatic Impairment | Dose reduction is required in patients with hepatic impairment. Methotrexate is contraindicated in severe hepatic impairment. Regular monitoring of liver enzymes is essential. |
| Maximum Daily Dose | The maximum dose varies widely by indication. For cancer, doses up to 12 g/m² have been used in specialized protocols. For autoimmune diseases, the maximum weekly dose is typically 25 mg. Doses must be determined by a qualified clinician. |
