| E.1.2 | Term | Hypertension |

| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| To assess the antihypertensive efficacy of adding spironolactone to the antihypertensive treatment of patients with resistant hypertension. |
|
| E.2.2 | Secondary objectives of the trial |
| To assess the safety of adding spironolactone to the antihypertensive treatment of patients with resistant hypertension. |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
Aged>18 years. Hypertension (essential or secondary) managed in Sheffield Hypertension Clinic or General Practice or both. Blood pressures not adequately controlled (SBP >140 mmHg and/or DBP >85 mmHg in clinic and on daytime mean ambulatory blood pressure monitoring) despite treatment with the maximum tolerated dose of 3 antihypertensive agents. Additional antihypertensive treatment deemed appropriate by the patients' doctor. Patients' current antihypertensive treatment includes a thiazide diuretic and a least one of: a beta blocker, angiotensin converting enzyme inhibitor or angiotensin II receptor antagonist (i.e. modern antihypertensive regime where spironolactone is least likely to be effective). |
|
| E.4 | Principal exclusion criteria |
Definite indication or contraindication for spironolactone. Known Conn's syndrome. Heart failure NYHA class III or IV. Known hepatic failure or significant cirrhosis. Known pregnancy or women planning pregnancy. Women of child-bearing potential not using adequate contraception methods. Serum creatinine >221 µmol/l. Serum potassium >5 mmol/l. Clinic blood pressure or daytime ambulatory blood pressure >240/120 mmHg.
