In Acute Kidney Injury (AKI), several classes of drugs should be avoided or used with extreme caution due to their potential to worsen kidney function or cause further damage. 1. Nephrotoxic Medications: NSAIDs (Non-Steroidal Anti-Inflammatory Drugs): Drugs like ibuprofen, naproxen, and diclofenac can reduce blood flow to the kidneys, especially in states of reduced renal perfusion. Certain Antibiotics: Aminoglycosides (e.g., gentamicin, amikacin) and vancomycin (especially at high doses or prolonged use) can be toxic to kidney tubules. Radiocontrast Agents: Used in imaging studies, these can cause contrast-induced nephropathy. 2. Medications Affecting Renal Perfusion or Function: ACE Inhibitors (Angiotensin-Converting Enzyme Inhibitors) and ARBs (Angiotensin II Receptor Blockers): While often used in CKD, they can precipitate AKI in situations of severe volume depletion or bilateral renal artery stenosis. Diuretics: Overuse can lead to dehydration and reduced kidney perfusion. Certain Antivirals: Such as foscarnet and cidofovir. 3. Medications Causing Obstruction: Sulfonamides and Methotrexate: Can precipitate in renal tubules, causing obstruction. It is crucial for healthcare providers to review a patient's medication list thoroughly when AKI is suspected or diagnosed and to adjust or discontinue any potentially harmful drugs.
