Healthcare Industry News: amlodipine besylate
News Release - March 31, 2008
Lotrel, a Single-Pill Combination for Treating High Blood Pressure, Reduced Cardiovascular Events by 20% in High-Risk PatientsACCOMPLISH first study to compare two single-pill combinations of commonly used high blood pressure medicines in reduction of cardiovascular events RAS inhibition with an ACEI was the foundation of the combination therapies in this study and exceptional blood pressure control rates were achieved
Further analyses of full data set will examine effects on specific patient populations
High dose formulations of benazepril/amlodipine besylate used in this study are only available as Lotrel 5/40 mg and 10/40 mg capsule
CHICAGO, March 31 (HSMN NewsFeed) -- Interim results from the ACCOMPLISH (Avoiding Cardiovascular Events through COMbination Therapy in Patients LIving with Systolic Hypertension) trial demonstrate that high-risk, high blood pressure patients treated with Lotrel® (amlodipine besylate and benazepril HCl) had 20% fewer cardiovascular events than those taking a benazepril and hydrochlorothiazide (HCTZ) combination. This is the first cardiovascular outcomes trial in a hypertensive population where all patients were randomized to receive a single-pill combination treatment at the onset of the trial as opposed to a step care regimen.
"These results suggest that the combination of the angiotensin-converting enzyme inhibitor (ACEI) and calcium channel blocker in Lotrel yielded better patient outcomes in high-risk hypertensive patients than the ACEI and HCTZ combination," explained Kenneth Jamerson, MD, professor of internal medicine at the University of Michigan Medical Center in Ann Arbor and lead investigator of the trial. "Further, a strategy of starting patients in the trial on a single-pill combination proved to be very efficient in significantly increasing blood pressure control rates."
Lotrel is approved for the treatment of high blood pressure. It should not be used before other medications have been tried first.
Treatment with combination therapy resulted in exceptional blood pressure control at 30 months. Before entering the study, almost all patients were treated with multiple high blood pressure medicines. At study entry, only 37% of the study population had a blood pressure of <140/90 mmHg, regarded in treatment guidelines as the appropriate goal for most patients. After switching to a single-pill combination of the study medications, 82% of patients taking Lotrel and 79% of patients taking the benazepril and HCTZ combination achieved blood pressure goal after 30 months. Some patients received additional medication to treat their high blood pressure.
"Evidence from trials like ACCOMPLISH provides physicians with additional information to better inform their treatment decisions in high-risk hypertensive patients," said Marjorie Gatlin, MD, Vice President and Head of Cardiovascular and Metabolism Medical Franchise US Medical and Drug Regulatory Affairs at Novartis Pharmaceuticals Corporation. "Novartis is an innovator of unique medications for the treatment of high blood pressure, including single- pill combinations, and is committed to further develop this approach for effective patient care."
The results were presented today in a late-breaking session at the American College of Cardiology 57th Annual Scientific Session in Chicago.
ACCOMPLISH is the first large clinical outcomes trial to directly compare two single-pill combinations of commonly used high blood pressure medicines in the reduction of a composite endpoint including heart attacks, strokes, hospitalizations for unstable angina and cardiovascular deaths in high blood pressure patients at high cardiovascular risk. In October 2007, the study was stopped early because the pre-defined efficacy outcome had been achieved.
The study was a multi-national, double-blind trial and included more than 11,000 patients at 550 study sites in the US and Scandinavia. One day after stopping their current high blood pressure medication, patients received a single-pill combination of either Lotrel or a combination of benazepril and HCTZ. In the first two months of the study, doses of study medications were increased. Patients in the Lotrel arm started on 5/20 mg. The dose was increased to Lotrel 5/40 mg and, for patients not at goal blood pressure, then to 10/40 mg. Patients taking benazepril and HCTZ started at 20/12.5 mg and were increased to 40/12.5 mg and, for patients not at goal blood pressure, to 40/25 mg. The combination doses of benazepril and HCTZ 40/12.5 mg and 40/25 mg used in this study were investigational. In both arms, patients were given additional blood pressure medication if goal blood pressure was not attained on the maximum dose of study medications.
The primary study endpoint was a composite of cardiovascular disease, non- fatal heart attack, non-fatal stroke, and hospitalization for unstable angina (chest pain that occurs when the heart muscle does not get enough blood) or revascularization (a procedure that re-establishes blood flow to previously restricted regions of the heart), and cardiovascular death. The full data will be available later this year and further analyses will examine the effects on specific patient populations.
Important safety information
LOTREL and the fixed dose combination of benazepril and HCTZ are prescription medications for the treatment of high blood pressure. They should not be used before other high blood pressure medications have been tried first.
LOTREL and the fixed dose combination of benazepril and HCTZ can harm an unborn baby and even cause death. If you get pregnant, stop taking LOTREL or the benazepril and HCTZ combination. Call your doctor right away. Talk to your doctor about other ways to lower your blood pressure if you plan to become pregnant.
Don't take LOTREL or the benazepril and HCTZ combination if you are allergic to any of the ingredients, or to any ACE inhibitor or for patients taking LOTREL, amlodipine. Do not take the benazepril and HCTZ combination if you have a history of reduced urine output, or have allergic reactions to certain drugs known as sulfonamides and tell your doctor if you have liver problems, lupus or if you take lithium. Your doctor or pharmacist can give you a complete list of the ingredients in LOTREL or the benazepril and HCTZ combination.
In rare cases with LOTREL or the benazepril and HCTZ combination, a potentially life-threatening allergic reaction (swelling of the mouth and throat) can occur. This potentially dangerous swelling of the mouth and throat has been reported more often in African American patients receiving ACE inhibitors than in non-African American patients.
The most serious side effect with LOTREL and the benazepril and HCTZ combination is low blood pressure.
The most common side effects in patients taking LOTREL and the benazepril and HCTZ combination include cough, dizziness, and headache, additionally with the benazepril and HCTZ combination fatigue and additionally with LOTREL, edema (swelling of the feet, ankles, legs, or hands).

40/12.5 mg and 40/25 mg used in this study were investigational and do not have approved prescribing information available.
About high blood pressure and treatment
High blood pressure increases a person's risk of experiencing a cardiovascular event. For example, it has been reported that the risk of heart attack and stroke doubles with every 20/10 mmHg increase in blood pressure, starting at 115/75 mmHg. Blood pressure treatment guidelines sponsored by the National Heart, Lung and Blood Institute recommend initial combination therapy of two medications that work differently for patients who have a systolic blood pressure of 20 mmHg and a diastolic blood pressure of 10 mmHg over target goal. Systolic blood pressure is the pressure of blood flow as the heart beats and pushes blood throughout the body. Diastolic blood pressure is between heart beats, as your heart rests and refills with blood.
Approximately 73 million adults (nearly one in three) in the US have high blood pressure. It has been estimated that most adults with high blood pressure also have additional health problems that increase their risk for cardiovascular events.
