What combinations increase NSAID nephrotoxicity risk dramatically?

'Triple whammy' combination: ACE inhibitor/ARB + diuretic + NSAID increases AKI risk 31.3× vs each drug alone. Risk factors: eGFR 65, concomitant nephrotoxins. NSAIDs should be avoided in CKD stage 3b+ (eGFR <45).

Are COX-2 selective NSAIDs safer for the kidneys?

No. COX-2 selective inhibitors (celecoxib, etoricoxib) cause equivalent renal toxicity to non-selective NSAIDs because COX-2 mediates renal prostaglandin synthesis responsible for maintaining GFR in low perfusion states. Cardiovascular thrombotic risk is higher with COX-2 inhibitors. Neither type is 'kidney-safe' in high-risk patients.
