EP4585207A1 — Synergic and stable pharmaceutical composition of an nsaid and an opioid analgesic for pain and inflammation

USPTO Abstract

The present invention relates to pharmaceutical compositions comprising etoricoxib and tramadol, or a pharmaceutically acceptable salt thereof, for the treatment of pain, which in addition to offering the possibility of an analgesic effect with a decrease in adverse events due to the reduction of the dose of one or both compounds, presents an improved stability, maintaining the dissolution and bioavailability of the composition to be administered; The composition manages to overcome the technological complexity that lies in having a drug with high sensitivity to light and humidity (tramadol), together with another fat-soluble drug with poor flow and excessive adhesiveness (etoricoxib), in a dispensing media in which their absorption is not affected through a water-free process, without affecting the release of both drugs.
