Thiazide-type diuretics for
most. May consider ACE

Two-drug combination for
most (usually including
thiazide-type diuretic)
Other antihypertensive
drugs (diuretics, ACE
inhibitor, ARB, β-blocker,
CCB) as needed
If not at goal, optimise dosages or add additional drugs until goal BP is achieved.
Consider consultation with hypertension specialist
*BP goal <140/90 mmHg or <130/80 mmHg for those
with diabetes or chronic kidney disease

Absence or presence of TOD and risk factors
Choose between:

ESH/ESC
JNC VII
Also Guidelines worldwide Acknowledge That Most
Patients Need Combination Therapy to Achieve BP Goals
Most patients with hypertension will require two or more
antihypertensive medications to achieve their BP goals
– When BP is > 20/10 mmHg above goal, consideration should
be given to initiating therapy with two drugs
•
Combination treatment should be considered as first choice
when there is high CV risk
– i.e., in individuals in whom BP is markedly above the
hypertension threshold (> 20/10 mmHg), or associated with
multiple risk factors sub-clinical organ damage, diabetes, renal
or CV disease
• Many patients will require more than one drug to achieve
adequate BP control
– Pathophysiological reasoning suggests that adding an ACE-I/ARB
to a CCB or a diuretic (or vice versa in the younger group) are
logical combinations
NICE
JSH
•
The Japanese Society of
Hypertension Committee for
Guidelines for the
Management of Hypertension
2009
• The use of two or three drugs in combination is often necessary
to achieve the target BP control
– A low dose of a diuretic should be included in this combination

RECOMMENDATIONS FOR COMBINING THERAPIES

needed to achieve BP goals

combining antihypertensive therapies

BENEFITS OF FIXED-DOSE COMBINATION
THERAPY
Rationale for fixed-dose combinations
(FDCs): efficacy; tolerability;
compliance and persistence
Beneficial impact of FDCs on
compliance and persistence, and costs
11
RATIONALE FOR THE USE OF FIXED-DOSE
COMBINATIONS: TOLERABILITY
FDC therapy may have an improved tolerability profile
compared with its single-mechanism components1,2
Low doses of two agents often result in fewer adverse
events than high doses of one agent1,2
– Physicians may accept less than optimal BP control to minimise
adverse events
Compound-specific adverse events can be attenuated,
e.g.1,2
– RAS blockers effectively blunt the metabolic effects of diuretics
– RAS blockers may attenuate the oedema that is caused by
calcium channel blockers (CCBs)

Why Telmisartan + Amlodipine,
because it
• Combines the best in class compounds –
unique PK/PD evidence – in a single-pill
combination
• Provides powerful and ‘smart’ BP
reductions and high 24h BP control
including patients with added-risk such as
diabetes and obese
• Has a safety & tolerability profile similar to36

RATIONALE FOR THE USE OF FIXED-DOSE COMBINATIONS:
COMPLIANCE AND PERSISTENCE
A single, once-daily pill simplifies the treatment
regimen compared with agents given as separate
pills
– Increases convenience for patients
– Reduces the pill burden
Increased convenience and lower pill burden likely
to improve compliance to and persistence with
antihypertensive medications
– Overcomes a major barrier to effective BP control
Likely to cost less than the individual components
prescribed separately

THE CCBARB TARGETS TWO KEY BP
EFFECTOR PATHWAYS (1)
Sympathetic nervous system (SNS)
SNS activity → noradrenaline binds to α1-adrenergic
receptors on vascular smooth muscle → vasoconstriction1
SNS also stimulates renin secretion from the kidney,
thereby activating the RAS2
CCBs inhibit SNS-induced vasoconstriction by blocking
influx of calcium ions (needed for contraction) through
voltage-gated calcium channels → vasodilation3,4
Other effects of CCBs: natriuresis; inhibition of aldosterone
release; interference with angiotensin II-mediated
vasoconstriction4

THE CCBARB TARGETS TWO KEY BP
EFFECTOR PATHWAYS (2)
Renin angiotensin system (RAS)
Release of renin catalyses conversion of
angiotensinogen into angiotensin I, which is
converted by ACE to angiotensin II →
– Vasoconstriction; increased aldosterone and sodium/water
retention; SNS activation
ARBs block the effects of angiotensin II by binding to
AT1 receptors
– Arterial and venous dilation
– Reduced SNS activity
– Reduced secretion of aldosterone and increased secretion of
sodium and water
