Abstract:
High-dose methotrexate is an effective and safe therapy. It is included in the treatment regimens of various hematologic and oncologic diseases. The acute and severe toxicity of this chemotherapeutic agent is unusual. Nephrotoxicity occurs in about 2-12% of patients, associated with a slow clearance of the drug. It is usually reversible but requires an early approach. The objective was to describe the case of a patient diagnosed with lymphoblastic leukemia who presented with acute kidney injury after the administration of high doses of methotrexate.

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
