   New data from the SEVITENSION study show the fixed-dose 
   combination treatment Sevikar® (olmesartan/amlodipine) to be 
   superior to perindopril in combination with amlodipine in reducing
   central blood pressure 

When the traditional arm (brachial) method of measurement is used, blood pressure is usually found to be higher than it is in the large central arteries.(1) Central blood pressure is believed to provide a more accurate reflection of the pressure experienced by the internal organs,(1) and there is an increasing amount of evidence from clinical studies to show that measures of central blood pressure predict damage to organs and the risk of disease- related events more accurately than brachial blood pressure.(2-4) The Conduit Artery Function Evaluation (CAFÉ) study, a substudy of the ground-breaking ASCOT study, showed that the treatment combinations used had different effects on central systolic aortic blood pressure, with a significant advantage for the perindopril and amlodipine combination.(5) "According to the investigators of the study, this advantage could potentially explain the differences in clinical outcomes between the two groups in the ASCOT study.(6) These findings are what inspired the SEVITENSION study" explained Professor Luis Ruilope, Head of the Hypertension Unit at 12 de Octubre Hospital, Madrid, Spain and Principal Investigator of the Sevitension study. "Post-marketing studies like these provide important insights to help physicians select the best treatment options to manage hypertension more effectively and conveniently and protect patients in a better way. And this potentially improved management will help achieve the ambitious goal of controlling the blood pressure (<140/90 mmHg) of 70% of hypertension patients by 2015."

Drugs like angiotensin-converting enzyme inhibitors (ACEIs) lower blood pressure by inhibiting the activity of the renin-angiotensin system (RAS). Another class of antihypertensive drugs known as angiotensin receptor blockers (ARBs) also lowers blood pressure by inhibiting the RAS, and offers the advantage of fewer side effects than ACEIs, in particular cough.(7)

Daiichi Sankyo actively supports research into treatments for hypertension and has developed a range of treatments based upon the ARB olmesartan. One of these treatments, a dual combination of olmesartan with amlodipine (Sevikar®), has now been used to address an important clinical question: can a dual combination of an ARB like olmesartan plus amlodipine lower central blood pressure as effectively as perindopril plus amlodipine? This question was addressed by the SEVITENSION study,(8) and the first findings from this study were revealed at an ESH 2013 poster session. (10)

SEVITENSION set out to show that olmesartan 40 mg/amlodipine 10 mg was non inferior to perindopril 8 mg/amlodipine 10 mg, the treatment used in the CAFÉ study, in lowering central blood pressure. The results show not only that this aim was achieved, but also that the reductions in central blood pressure went beyond this and met the criteria of a test for superiority defined by the European Agency for the Evaluation of Medicinal Products.(9) This means that olmesartan 40 mg/amlodipine 10 mg was shown to be superior to perindopril 8 mg/amlodipine 10 mg.(10) Other secondary endpoints including standard brachial blood pressure and ambulatory blood pressure measurements made over 24 hours also confirmed that olmesartan 40 mg/amlodipine 10 mg was superior. Another important finding was that three quarters (75.6%) of patients treated with olmesartan 40 mg/amlodipine 10 mg were able to 'normalise' their blood pressure(10) so that it fell below the level (<140/90 mmHg) recommended by the European Society of Hypertension for all patients with hypertension.11 The proportion of patients who achieved this level of blood pressure with the perindopril 8 mg/amlodipine 10 mg combination was nearly 20% lower (57.5%). "The gold standard since the publication of the CAFÉ study has been the combination of perindopril 8 mg/amlodipine 10 mg and we compared this with olmesartan 40 mg/amlodipine 10 mg which lowered central blood pressure levels significantly more. The better the response of blood pressure the lower could be the chance of suffering cardiovascular events," commented Professor Luis Ruilope, the lead investigator of the SEVITENSION study.


About Sevikar

Sevikar is a fixed-dose combination of olmesartan and amlodipine:(12)

   - Olmesartan is an angiotensin II receptor antagonist or blocker
     (ARB) which works by inhibiting the action of the RAS by
     blocking the action of a hormone called angiotensin-II.
     Angiotensin-II causes blood vessels to narrow       
     (vasoconstriction) and leads to the production of another       
     hormone called aldosterone which is responsible for fluid       
     retention. By preventing the action of angiotensin-II,       
     olmesartan widens blood vessels and reduces fluid in the blood
     lowering the blood pressure.     

   - Amlodipine is a long-acting calcium channel blocker indicated to
     reduce blood pressure. Amlodipine acts by relaxing the smooth 
     muscles in artery walls decreasing total peripheral resistance 
     and hence reducing blood pressure. 

About Combination Therapy (According to the European Guidelines on Hypertension Management)(11)

Several two-drug combinations are suitable for clinical use. However, trial evidence of outcome reduction has been obtained particularly for the combination of a diuretic with an ACE inhibitor or an angiotensin receptor antagonist or a calcium antagonist, and in recent large-scale trials for the ACE inhibitor/calcium antagonist combination. The angiotensin receptor antagonist/calcium antagonist combination also appears to be rational and effective.(11)

In no less than 15-20% of hypertensive patients, BP control cannot be achieved by a two-drug combination. When three drugs are required, the most rational combination appears to be a blocker of the renin-angiotensin system, a calcium antagonist, and a diuretic at effective doses.(11)
