A comparison of wax matrix and microencapsulated potassium chloride in relation to upper gastrointestinal illness requiring hospitalization.
The frequency of hospitalization for documented upper gastrointestinal illness among recipients of either wax matrix or microencapsulated potassium chloride was similar in a study in which clinics were randomly assigned to dispense one or the other preparation. The results indicate that there is no material difference between the two preparations in relation to serious upper gastrointestinal illness.
