BACKGROUND: Chronic use of NSAIDs is associated with gastrointestinal (GI) toxicity that increases with age.
AIM: To evaluate the GI safety and therapeutic efficacy of ibuprofen chemically associated with phosphatidylcholine (PC) in osteoarthritic (OA) patients.
METHODS: A randomized, double-blind trial of 125 patients was performed. A dose of 2400 mg/day of ibuprofen or an equivalent dose of ibuprofen-PC was administered for 6 weeks. GI safety was assessed by endoscopy. Efficacy was assessed by scores of analgesia and anti-inflammatory activity. Bioavailability of ibuprofen was pharmacokinetically assessed.
RESULTS: Ibuprofen-PC and ibuprofen provided similar bioavailability/therapeutic efficacy. In the evaluable subjects, a trend for improved GI safety in the ibuprofen-PC group compared with ibuprofen that did not reach statistical significance was observed. However, in patients aged >55 years, a statistically significant advantage for ibuprofen-PC treatment vs. ibuprofen in the prevention of NSAID-induced gut injury was observed with increases in both mean Lanza scores and the risk of developing >2 erosions or an ulcer. Ibuprofen-PC was well tolerated with no major adverse events observed.
CONCLUSION: Ibuprofen-PC is an effective osteoarthritic agent with an improved GI safety profile compared with ibuprofen in older OA patients, who are most susceptible to NSAID-induced gastroduodenal injury.
