(Headquarters: Chuo-ku, Tokyo; President & CEO: Masafumi Nogimori) announced today that on 22 April the approval of manufacture and marketing of Micombi®Combination Tablets was obtained. Micombi® is a combination drug of telmisartan, an angiotensin II receptor blocker (ARB), and hydrochlorothiazide (HCTZ), a diuretic of the thiazide class.  Micombi®Combination Tablets will be manufactured by Nippon Boehringer Ingelheim, distributed by Astellas Pharma, and co-promoted by both companies as are the telmisartan drug Micardis® Tablets.

In a Japanese clinical trial, Micombi®Combination Tablets AP demonstrated a very strong antihypertensive effect, lowering systolic blood pressure by -23.3 mmHg from baseline at the end of the trial.1 Micombi®Combination Tablets offer a very strong antihypertensive effect by a convenient single dose administration which is expected to contribute to improving medication adherence.2

About telmisartan
Telmisartan is a member of the angiotensin II receptor blocker (ARB) * class and is undergoing many clinical studies for the verification of its efficacy.  A single agent Telmisartan is marketed as Micardis®, while Micombi® is to join the line-up as a combination drug.  Landmark clinical trial programmes including ONTARGET®4 and PRoFESS®5 have been conducted, enrolling a total of 58,000 subjects or more for investigation of the efficacy of Telmisartan in preventing cardiovascular events. These landmark trials proved the favourable profile of Telmisartan in preventing cardiovascular events.
*Angiotensin II receptor blocker: antihypertensive treatment drug that selectively blocks the angiotensin II AT1 receptor.  The blockade is thought to cause vasodilation and prevent cell proliferation.

Telmisartan was discovered and developed by Boehringer Ingelheim. The company markets telmisartan in nearly 100 countries, including USA, Japan and European countries.  Telmisartan drug Micardis® Tablets are manufactured by Nippon Boehringer Ingelheim, distributed by Astellas Pharma, and co-promoted by both companies in Japan. Micombi®Combination Tablets are planned to be introduced to the Japanese market by both companies in the same way. Both Micardis® Tablets and Micombi®Combination Tablets are indicated for hypertension in Japan.
