Study objectivesThis will be a study in patients with Polycystic Kidney Disease (PKD) and hypertension designed to evaluate:
1. Individual responsiveness to 5 main drug groups:
1.1. Angiotensin Converting Enzyme (ACE)-inhibitor
1.2. Alpha-blockade
1.3. Beta-blockade
1.4. Diuretic
1.5. Calcium antagonist, and

Health condition(s) or problem(s) studiedCardiovascular: Hypertension
InterventionFollowing a 2-week placebo run-in period, patients eligible to enter this crossover, double-blind study will receive in a randomised order, daily, and for a six week period:
1. Amlodipine (5 mg)
2. Doxazosin (1 mg increasing to 4 mg)
3. Lisinopril (2.5 mg increasing to 10 mg)
4. Benrofluazide (2.5 mg)
5. Bisoprolol (5 mg)
6. Placebo

Patients will then receive an additional six weeks treatment with the agent that produced the greatest lowering of mean supine blood pressure.

Updated 16/05/2014: the trial was stopped in 2008 due to a lack of funding.
