From the Guidelines
Etoricoxib can potentially affect both the stomach and kidneys, though it generally has less stomach impact than traditional NSAIDs. Etoricoxib is a COX-2 selective inhibitor that was designed to reduce gastrointestinal side effects compared to non-selective NSAIDs like ibuprofen or naproxen 1. However, it still carries some risk of stomach problems, particularly at higher doses or with prolonged use, including ulcers and bleeding, especially in high-risk individuals. Some key points to consider when using etoricoxib include:
- The risk of serious gastrointestinal adverse events is lower with etoricoxib compared to traditional NSAIDs, but still present 1
- Etoricoxib can reduce kidney blood flow and potentially cause kidney injury, particularly in people with pre-existing kidney disease, heart failure, liver disease, or dehydration 1
- Patients taking blood pressure medications, diuretics, or who have cardiovascular disease should use etoricoxib cautiously, as it may increase cardiovascular risks 1
- The elderly are especially vulnerable to these effects, and anyone with a history of heart problems should be particularly careful when using etoricoxib 1 It is essential to take the lowest effective dose for the shortest time necessary, stay well-hydrated, and promptly report any concerning symptoms to your healthcare provider when using etoricoxib.
From the Research
Etoricoxib's Effect on the Stomach
- Etoricoxib has been shown to have a lower risk of gastrointestinal adverse events compared to non-selective nonsteroidal anti-inflammatory drugs (NSAIDs) 2.
- A study found that the incidence of endoscopically detected ulcers was significantly lower with etoricoxib 120 mg than with ibuprofen 2400 mg 2.
- Etoricoxib therapy was not associated with exacerbation of underlying inflammatory bowel disease (IBD) or GI-related complications in patients with IBD 3.
- The gastrointestinal safety profile of etoricoxib is similar to that of first-generation coxibs, with a significant reduction in symptomatic ulcers and ulcer complications compared to ns-NSAIDs 4.
Etoricoxib's Effect on the Kidneys
- A study examined the effect of renal insufficiency on the pharmacokinetics of etoricoxib and found that even severe renal impairment had little effect on etoricoxib pharmacokinetics 5.
- The use of etoricoxib is not recommended in patients with advanced renal disease (creatinine clearance below 30 mL/min/1.73 m2) due to the potential for further compromise of renal function 5.
- The incidence of renal adverse events, including hypertension, lower-extremity edema, elevated serum creatinine concentration, and congestive heart failure, was low and generally similar between etoricoxib and comparator NSAIDs 6.
- Etoricoxib has been shown to have a low risk of renal adverse events, with a shallow dose response, and is generally similar to comparator NSAIDs 6.
