Exforge Helps Nearly Twice as Many Patients Control Their High Blood Pressure Compared to Amlodipine Alone
New data show that patients on Exforge with baseline blood pressure greater than or equal to 180 mmHg experienced significant reductions of up to 40 mmHg to help reach target levels
EAST HANOVER, N.J., July 28, 2008 /PRNewswire/ -- New data show Exforge (amlodipine and valsartan), a single-pill combination of the world's leading high blood pressure medicines Diovan (valsartan) and amlodipine, gets nearly twice as many patients with high baseline blood pressure to a healthier blood pressure goal compared to amlodipine alone.
Results of a study in patients with baseline systolic blood pressure greater than or equal to 160 mmHg published in The Journal of the American Society of Hypertension, showed that 51.8% of patients on Exforge achieved systolic blood pressure control, defined as <140 mmHg at week four, compared to 27.7% of those on amlodipine alone. Systolic blood pressure, measured when the heart contracts and pumps, is an important indicator of a person's risk of cardiovascular events.
The primary endpoint of the study was the change from baseline Mean Sitting Systolic Blood Pressure (MSSBP) at week four. Results showed that on average, patients on Exforge experienced a significant 30.1 mmHg reduction in systolic blood pressure compared to a 23.5 mmHg reduction in patients on amlodipine alone.
In the same study, patients with systolic blood pressure greater than or equal to 180 mmHg treated with Exforge experienced significant systolic blood pressure reductions of up to 40.1 mmHg, compared with 31.7 mmHg for those treated with amlodipine alone. High blood pressure is estimated to affect one in three adults in the US -- approximately 73 million adults.
"All patients who received Exforge achieved significant blood pressure drops, with the bigger blood pressure drops of up to 40 mmHg being seen in those patients with a higher baseline level," said Maurizio Destro, MD, the lead investigator from the Azienda Ospedaliera di Pavia in Italy. "In addition, Exforge was well tolerated which is important for patients in managing their blood pressure."
Treatment guidelines recommend that patients with high blood pressure greater than or equal to 160/100 mmHg should be considered for a combination of two medicines from different drug classes.
Exforge also demonstrated significantly better blood pressure-lowering efficacy than amlodipine alone across certain difficult-to-treat patient groups, including the elderly (over 65 years), obese people and those with diabetes.
"Exforge has shown significant benefit in difficult-to-treat patients with high blood pressure," said Marjorie Gatlin, MD, Vice President and Head of Cardiovascular and Metabolism Medical Franchise, US Medical and Drug Regulatory Affairs at Novartis Pharmaceuticals Corporation. "This is important as high blood pressure remains a highly prevalent condition and underlying cause of cardiovascular disease."
The study was designed to investigate and compare the efficacy and safety of Exforge with amlodipine in patients with stage 2 high blood pressure (a more severe stage of the disease, with systolic blood pressure between 160 and 200 mmHg). It was a randomized, double-blind, multi-center parallel-group study carried out in 75 centers across Europe and the US. In total, 646 patients were randomized to receive treatment with Exforge 5-10/160 mg (n=322) or amlodipine 5-10 mg (n=324). Demographic and high blood pressure baseline characteristics were similar for both groups.
Overall blood pressure measurements consist of two values, both expressed in millimeters of mercury (mmHg). The first is the systolic blood pressure when the heart beats and the second is the diastolic pressure when the heart relaxes between beats. In this study, overall blood pressure control rates (<140>

IMPORTANT WARNING: Taking Diovan, Tekturna or Exforge during pregnancy can cause injury and even death to your unborn baby. If you get pregnant, stop taking Diovan, Tekturna or Exforge and call your doctor right away. Talk to your doctor about other ways to lower your blood pressure if you plan to become pregnant.
Do not take Diovan, Tekturna or Exforge if you are allergic to any of the ingredients in the product you are taking. Additionally, do not take Tekturna if you take cyclosporine. If you take Tekturna or Exforge, tell your doctor if you have kidney problems.

The most serious side effect with Diovan, Tekturna and Exforge is low blood pressure, and additionally with Diovan kidney problems.
In clinical studies, diarrhea was experienced by more patients taking Tekturna than patients taking a sugar pill. Other less common reactions to Tekturna include cough and rash. Side effects that occur more frequently with Exforge than placebo are swelling of the hands, ankles, or feet; nasal congestion or sore throat; head or chest cold; and dizziness.
