1. SBP: Home readings are an average of 3 daily blood pressure readings prior to the date of
review. They also help to exclude symptomatic hypotension before any increase in medication. Clinic blood pressure readings are required before any new drug is added.
In the Standard regime, medication changes are indicated if SBP outside target range (130-
140mmHg systolic) on an average of the last 2 out of 3 readings, unless home readings show
consistent readings below 130 mm Hg. If any clinic reading were below 130mmHg then antihypertensive medication withdrawal would be indicated.
In the Intensive treatment arm, medication changes are indicated if any SBP were over
125mmHg systolic unless home readings show consistent readings below 110 mm Hg.
2. Calcium channel blocker (CCB): First line antihypertensive therapy if patient is older
than 55 years old (or Afro-Caribbean). Non-rate control CCB such as Amlodipine 5mg od (5- 10mg od), Nifedipine MR/LA 20 or 30 mg od (range 20, 30, 40, 60 mg od). Peripheraloedema is a common side effect and although benign, may need to have dose reduction or discontinuation depending on patient comfort. Combination with long acting thiazide diuretic or ACEI can minimise peripheral oedema.
3. Angiotensin converting enzyme inhibitors (ACEi): First line antihypertensive therapy
in patients less than 55 years old with normal kidney function.
Monitor renal function 1-2 weeks after ACEI initiated. Start Lisinopril at 10-20 mg per day (up to 80 mg per day). Some experts prefer to use Lisinopril twice a day when in high doses.
Others include Perindopril 2mg od (range 2, 4, 8mg od), Ramipril 2.5mg od (range 1.25, 2.5, If intolerant or develops cough, consider substituting with an Angiotensin receptor
blocker (ARB) e.g. Losartan 50mg od (up to 100mg od), Candesartan 8mg per day (up to 32
4. Thiazide diuretic (D): In patients with normal kidney function start
Bendroflumethiazide 2.5mg od. In patients with decreased eGFR (<30 ml/minute/1.73m2), loop diuretics may be used instead (Furosemide 80mg od).
5. Beta Blocker (BB): Atenolol 25-100mg od (in some cases such as patients with kidney
failure, 12.5 mg daily could be adequate). Bisoprolol 10mg od (5-20mg od). Monitor HR and
do not titrate dose up if resting HR is <60 bpm
6. Potassium sparing diuretic (PSD): Spironolactone 25 mg od (12.5-200mg od) or
7. Alpha-receptor antagonist (ARA): Doxazosin 4mg od (4-16mg od). This is an effective
vasodilator. Ideally add to regimens that include a diuretic and a rate-controlling agent like a BB. Monitor for CHF and volume overload carefully.
8. Centrally active antihypertensive (CAB): Discontinue beta-blocker before starting
Moxonidine 200 micrograms od (200-600 micrograms od) Increase dose in the following order ‘ACEi’, ‘CCB’, ‘ARA’, ‘BB’, ‘PSD
Add drugs in the following order: ACEi, CCB, ARA, PSD, BB, CAB
Withdraw or reduce dose of last added drug
