In a random crossover study in general practice, sixty patients with heart failure were given one week's maintenance treatment with the recommended dosage of Burinex K or Lasix+K. Burinex K appeared to be easier to swallow than the supplement tablets of Lasix+K although the differences were not significant. Patients showed a highly significant preference to take two tablets on one occasion (Burinex K) rather than two different types of tablet on three separate occasions (Lasix+K). Despite pharmacological arguments in favour of stimultaneous versus separate administration of potassium supplement and diuretic, patient acceptibility is of over-riding importance in the long-term.
