Comparison of the taste and acceptance of three potassium chloride preparations

The palatability and acceptance of three commercially available potassium chloride solutions were evaluated. Adult ambulatory patients routinely self-administering potassium chloride solution rate the palatability and acceptance of each preparation. An open-label, three-treatment crossover study design was used. The taste of Klorvess was rated significantly more palatable than Kaochlor (p less than 0.01) or KayCiel (p less than 0.05). Klorvess was rated significantly more acceptable if taken over a long period of time than Kaochlor (p less than 0.01) or KayCiel (p less than 0.01). The average amount consumed of all three products was 57% of the prescribed amount. The amount of Klorvess returned was significantly less than the amount of either KayCiel (p less than 0.01) or Kaochlor (p less than 0.01). The flavoring agents are described and the importance of ensuring that the patient uses an accurate measuring spoon is discussed.
