Fosrenol(R) is a non-aluminium, non calcium phosphate binder that has a very high affinity for dietary phosphate, forming lanthanum phosphate, which passes through the intestines and is eliminated from the body, leading to effective reduction in serum phosphorus levels. CPFilms' parent company, Solutia, has patents on IR-absorbing layers of lanthanum hexaboride, antimony-tin oxide, and indium-tin oxide.
