No results posted yet for this study

Summary

Etoricoxib and cyclobenzaprine hydrochloride are active pharmaceutical ingredients (APIs) already registered in the country as mono-drugs. These products are widely used for the proposed indications, and their safety and efficacy profiles are known in daily clinical practice. Once the absence of a pharmacokinetic interaction between etoricoxib and cyclobenzaprine hydrochloride has been confirmed in relative bioavailability studies, this phase 3 study will be conducted for demonstrating the superiority of the new FDC over etoricoxib 90 mg (Arcoxia®) and cyclobenzaprine hydrochloride 15 mg (XL - Mitrul®) in the treatment of moderate to serious pain associated with muscle spasm. The purpose is to provide a new, effective, and safe therapeutic option to address these cases.
