    Abstract: A formulation comprising, and process for preparing, improved oral dosage forms of 1-(5-tert-butyl-2-p-tolyl-2H-pyrazol-3-yl)-3-[4-(2-morpholin-4-yl-ethoxy)-naphthalen-1-yl]-urea, a chemical entity with anti-inflammatory properties. Granulation of 1-(5-tert-but l-2-p-tolyl-2H-pyrazol-3-yl)-3-[4-(2-morpholin-4-yl-ethoxy)-naphthalen-1-yl]-urea within specified ranges provides improved dissolution of 1-(5-tert-butyl-2-p-tolyl-2H-pyrazol-3-yl)-3-[4-(2-morpholin-4-yl-ethoxy)-naphthalen-1-yl]-urea and oral bioavailability, as well as content uniformity. Incorporation into the formulation of an aqueous soluble inclusion compound capable of forming a complex with 1-(5-tert-butyl-2-p-tolyl-2H-pyrazol-3-yl)-3-[4-(2-morpholin-4-yl-ethoxy)-naphthalen-1-yl]-urea, such as beta-cyclodextrin provides enhanced stability of 1-(5-tert-butyl-2-p-tolyl-2H-pyrazol-3-yl)-3-[4-(2-morpholin-4-yl-ethoxy)-naphthalen-1-yl]-urea, in particular in highly ionic environments. Chipping and disintegration of tablets containing more than about 10% betacyclodextrin can be prevented by applying a polymeric coat to the surface of the tablet at a temperature below 40° C.
