Claim:
A method of packaging a rapidly bioavailable diclofenac potassium tablet comprising: a) formulating a 50 mg. diclofenac potassium tablet dosage form 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, and ii) from about 30 to about 80 wt % of a hygroscopic diluent 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.; and b) packaging said dosage form in a moisture resistant bottle that prevents said dosage form from absorbing more than 4 wt. % moisture in three months when stored at 40° C. and 75% relative humidity.
