Matrix Microparticles Of Copaiba Oil (Copaifera Langsdorffii) On Renal Physiology: Patent Review

PURPOSE: to demonstrate the effect of matrix microparticles of Copaifera langsdorffii (aerial parts of copaiba), aiming to evaluate the discussions and results of the works that demonstrate Its function on the kidneys as well as its effectiveness. METHODS: A bibliographic study was carried out by consulting public online databases of patents, such as the United States Patent and Trademark office, World Intellectual Property Organization and the National Intellectual Property Institute; The following keywords were used: copaiba oil, renal function, kidney, kidney stones, matrix microparticles Copaifera langsdorffii and lithiasis. In this study were included patents of invention, innovations and utility models in the period from January 2007 to May 2016. RESULTS: One patent register was included regarding a method for obtaining microparticles and compounds, having antilithiasic, analgesic, antispasmodic, anti-inflammatory, diuretic and antiseptic activity. CONCLUSION: The patent registry survey demonstrates the possibility of beneficial action of matrix microparticles Copaifera langsdorffii on renal physiology, acting as antilithiasis and even with diuretic properties, thus opening up new possibilities of research of this substance on renal physiology.
