    Journal: Clin Nephrol; 1993 Jan; 39(1):37-43. PubMed ID: 8428406.
    Abstract:
    The efficacy of transdermally administered clonidine was evaluated in twenty-four patients with mild-to-moderate hypertension (seated diastolic blood pressure 95-115 mmHg) and renal impairment. Patients were initially treated with oral clonidine; the dose was titrated until the seated diastolic pressure fell below 90 mmHg or a minimum 10% reduction in baseline was achieved. Oral clonidine produced a significant decrease in both systolic and diastolic blood pressure; mean seated diastolic blood pressure decreased 16.9 mmHg from baseline. When transdermal clonidine was substituted for twice daily dosage of oral clonidine, blood pressure decreases were fully maintained. Sixteen patients completed three months of stable-dose transdermal therapy. The results suggest that, in mild-to-moderate hypertensive patients with chronic renal impairment, blood pressure can be controlled with a once-weekly application of transdermal clonidine as effectively as with oral clonidine. Mean diastolic blood pressure was decreased approximately 17% during clonidine therapy independent of the severity of renal dysfunction or route of clonidine administration.
