More Information
Summary:The present invention relates to stable, ophthalmic pharmaceutical formulations of the phosphodiesterase-4 inhibitor, roflumilast, and methods of making the same. Novel ophthalmic pharmaceutical formulations of roflumilast can comprise a viscosity agent, a surfactant, and a buffer. In preferred embodiments, the pH of the ophthalmic pharmaceutical composition is between 6.0 and 6.7. Methods of making stable, ophthalmic pharmaceutical formulations of roflumilast can include separate active and inactive ingredient processes. Further, the methods can include clarity filtration to mitigate particle size aggregation and to create an optimized suspension. Further, the methods can include terminal sterilization of the final drug product.
