Scientific title | |
Study objectives | The aim of the present study was: 1. To compare drug regimen compliance in hypertensives treated with combination therapy whose blood pressure (BP) was controlled versus uncontrolled after four weeks of self-monitored BP measurement. 2. To observe the consequences in uncontrolled patients of switching one drug of the combination therapy to candesartan/HCTZ (16 mg/12.5 mg) with and without a compliance intervention program. |
Ethics approval(s) | Ethics approval gained from the Ethics Committee of the university of Bonn on 12th December 2000 (reference No.:150/00). |
Health condition(s) or problem(s) studied | Resistant arterial hypertension |
Intervention | Patients with oBP of more than 140/90 mmHg despite combination therapy were begun on microelectromechanical systems (MEMS) monitoring and self BP measurement for four weeks of run-in. Of 62 such patients, 18 (29%) were normotensive according to self BP measurement and ambulatory BP measurement at four weeks (Group A); in the remaining 44 still uncontrolled patients, candesartan/HCTZ was substituted for one of the combination therapy drugs, with half these patients receiving passive compliance monitoring (Group B) and the other half in the Drug Regimen Compliance (DRC) intervention program (Group C). All groups were then followed for eight weeks. |
