ABSTRACT:
A pharmaceutical dosage form is prepared from a multiplicity of coated potassium chloride crystals coated with two distinct layers, the first of ethylcellulose and the second of a hydrophilic coating polymer, preferably hydroxypropylcellulose, resulting in microcapsules. These microcapsules are capable of being compressed into tablets of suitable hardness and friability with minimum quantities of excipients. The resultant controlled release tablets are useful for treatment of potassium deficiencies in humans.
