Questionnaire survey and serum phosphorus levels in maintenance hemodialysis patients switching lanthanum carbonate formulation from chewable tablets to granules.

We conducted a questionnaire survey of 79 maintenance hemodialysis patients switching lanthanum carbonate (LC) formulation from chewable tablets to granules, to investigate the compliance and patient preferences of these two formulations. For the number of times chewed when taking chewable tablets, the ratio of patients who responded 10 times or more was 54.4%, who responded four to nine times was 24.
