Osteoporosis
Intervention
The Calci-Chew D3 chewable tablets (Nycomed, Denmark) contained 1250 mg of calcium carbonate (equivalent to 500 mg elemental calcium) and 400 IU of cholecalciferol (equivalent to 10 µg vitamin D3). The sachet of calcium plus vitamin D3 (Cad, Will-Pharma) contained 1250 mg of calcium carbonate (equivalent to 500 mg elemental calcium) and 440 IU of vitamin D3.
The patients received both trial medications for 14 days, which was considered adequate for a patient to become familiar with the formulation and to assess the preference and acceptability. The patients received either the chewable tablet for two weeks followed by the sachet for two weeks or vice versa.
