Dexibuprofen: pharmacology, therapeutic uses and safety.

Dexibuprofen is the single pharmacologically effective enantiomer of rac-ibuprofen. Racibuprofen and dexibuprofen differ in their physico-chemical properties, in terms of their pharmacological properties and their metabolic profiles. Several clinical trials and post-marketing surveillance studies were performed to broaden the findings on dexibuprofen. In the last 5 years 4836 patients have been exposed to dexibuprofen in clinical trials and PMS trials. Only in 3.7% of patients adverse drug reactions have been reported and 3 serious adverse drug reactions (0.06%) were observed. In the dose ratio of 1 : 0.5 (rac-ibuprofen vs. dexibuprofen) at least equivalent efficacy was proven in acute mild to severe somatic and visceral pain models. Dexibuprofen has proven at least comparable efficacy to diclofenac, naproxen and celecoxib and has shown a favourable tolerability. The results suggest that dexibuprofen processed in a special crystal form is a safe and effective treatment for different pain conditions.
