Achieving Blood Pressure Goal: From Clinical
Trial into Real-World Data
Hypertension remains a leading cause of mortalityAnnually over 7 million deaths world-wide associated with hypertension
Hypertension causes a large direct and indirect economic burden
accounted for $73.4 billion in US in 20091
responsible for ~7.6 million deaths worldwide in 20012
The global incidence of hypertension is increasing3
Less than 50% of hypertensive patients in US receive therapy. In Canada and Europe approximately 66-75% were untreated4
Approximately 70% of patients do not reach BP goals.

When and Which Anti-hypertension
Combination?
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
Chobanian et al. JAMA. 2003;289:2560–2572; Mancia et al. Eur Heart J. 2007;28:1462–1536; http://www.nice.org.uk/
download.aspx?o=CG034fullguideline (accessed January 2010); Ogihara et al. Hypertens Res. 2009;32:3–107.
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
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

Inclusion criteria: male and female adult patients (age > 18
years) who consented to have their data collected, suffering from
essential hypertension not adequately controlled by monotherapy,
for whom an antihypertensive therapy with amlodipine/valsartan
combination (5/80, 5/160 or 10/160) daily was given at the
discretion of the attending physicians.
Objectives: The clinical EXCITE study evaluated the
effectiveness, safety, tolerability and treatment adherence of
Aml/Val Single Pill Combinations (SPCs) in patients with arterial
hypertension studied in a real-world setting.
Total patients recruited were 500 patients, 464 (92.8%) patients
completed the study, and 35 (7%) patients discontinued the study
due to lost to follow-up. Study period: Mar 2011 to Sept 2012

Objectives: This observational study was conducted to assess
safety, tolerability, and effectiveness of single pill combination
(SPC) amlodipine/valsartan in Indonesian hypertensive patients in
daily clinical practice.
Total patients recruited were 488 patients, 480 patients were
analyzed for safety and 468 patients were eligible for ITT

• From 480 patients eligible for safety analysis,
10 patients (2.1%) reported AE. Three
patients (0.6%) with mild AE were suspected
to be related to study drug : 2 patients (0.4%)
with edema, and 1 patient (0.2%) with
headache.
• Total of 2 patients (0.4%) with edema already
had edema at baseline.
• No serious AE (SAEs) reported in this
study.
Conclusion: This study showed that in patients
with essential hypertension not adequately
controlled by monotherapy, switching to
amlodipine/valsartan combination resulted in
further decrease in BP and achieved target BP
with good safety, tolerability and effectiveness,
suggesting the use of this combination can be
recommended in daily clinical practice in
Indonesia.
• From 500 patients in the full analysis set, 57
patients (11.4%) reported at least one AE.
The most frequent AEs were dyslipidemia (13
patients, 3%), cough (9 patients, 2%),
headache (7 patients, 1%), and edema (6
patients, 1%).
• 5 (1%) patients reported serious adverse
events (SAE), four patients died due to stroke
or heart attacks, one patient reported a non-
fatal SAE. The events were not suspected to
be related to the study drug.
Conclusion: The Indonesian EXCITE study
analysis showed that in a real-world setting,
amlodipine/valsartan SPC is an effective and
well-tolerated SPC therapy for the
hypertensive population in Indonesia
Summary Hypertension is a major CV risk factor. There are still unmet need in
the treatment of hypertension, with many patients are uncontrolled.
Most of the patients need more than one agent to achieve BP target.
CCB/ARB combination are recommended by guideline as preferred
combination for its efficacy, safety and tolerability profile.
Amlodipine/Valsartan combination provides powerful BP reductions,
favorable safety profile, as well as high BP goal and response rates,
for hypertensive patients including those with comorbidities.
Real-world experiences on SPC of amlodipine/valsartan in Indonesia
show consistent BP reduction powerful effectiveness with good
safety and tolerability in overall hypertensive patients and patients
with comorbidities.
