Claim:
A method comprising: a) providing a moisture resistant package that prevents the dosage form described in step (b) from absorbing more than 4 wt. % moisture in three months when stored at 40° C. and 75% relative humidity; b) providing a 10-60 mg. diclofenac potassium solid oral tablet dosage form formulated for rapid bioavailability, in a formulation comprising: i) at least 20 wt. % of one or more alkali metal carbonate or bicarbonate salt excipients that are freely soluble in water, based on the weight of diclofenac in its acid form; and ii) from about 30 to about 80 wt % of a hygroscopic diluent based on the weight of the tablet and said one or more freely soluble diluents at a weight ratio of from about 1:20 to about 5:1, wherein said hygroscopic diluent absorbs greater than about 0.5 wt. % water within a twenty four hour period in a humidity chamber maintained at 60% relative humidity (“RH”) and 25° C.; c) providing said dosage form in said package; and d) administering said dosage form to a human in need thereof.
