Propranolol in hypertensive dialysis patients: efficacy and compliance.

The effect of propranolol therapy on plasma renin activity and blood pressure control was evaluated in 35 uremic patients receiving intermittent center-based outpatient hemodialysis. Patients were determined to be either compliant or noncompliant with therapy based on the steady-state predialysis plasma propranolol concentration. Noncompliance occurred with remarkable frequency and was associated with persistent hyperreninemia and poorly controlled hypertension. Blood pressure control was significantly better in compliant patients, in whom plasma renin activity was generally, but not universally, suppressed. Propranolol can be effectively used in the management of hypertensive dialysis patients, but steady-state plasma propranolol levels should be measured to assess compliance in patients apparently refractory to treatment.
