Study Says Bristol-Myers Blood-Pressure Drug Better Than Pfizer's May 15, 1998 3:35 PM NEW YORK -(Dow Jones)- A study conducted by the University of Tennessee-Memphis showed that Bristol-Myers Squibb Co.'s Monopril product reduced the risk of a heart attack or stroke in patients with diabetes and hypertension by 51% compared to Pfizer Inc.'s Norvasc. The university said physicians have assumed that if a drug can reduce blood pressure, it should offer equal protection against cardiovascular events, but this study "suggests blood pressure reduction alone might not be a sufficient marker of drug efficacy." The university said two additional trials are under way or planned as follow-ups to the completed study. The study was published in the April issue of Diabetes Care and presented at the American Society of Hypertension annual meeting. Monopril is an angiotensin converting enzyme, or ACE, inhibitor fosinopril. Norvasc is a long-acting calcium channel blocker, or CCB, amlodipine. CCBs are among the most frequently used therapies for preventing cardiovascular events in diabetic hypertensive patients, according to the university. Bristol-Myers Squibb (BMY) and Pfizer (PFE) officials declined comment. The study focused on 380 patients with diabetes and hypertension for up to three-and-a-half years. A randomized, double-blind clinical trial of 104 patients is under way as a further study. An additional follow-up study that will examine 307 hypertensive patients with left ventricular hypertrophy is expected to be complete by early 1999, the university said.
