| Physicians
do not expect to decrease their prescribing of ACE inhibitors to control hypertension,
according to a survey of 300 physicians conducted by the New Jersey research firm
Market Measures/Corzint. The
findings may be surprising in light of recent findings from the controversial
ALLHAT clinical trial that found diuretics to be superior among other hypertensive
drugs in preventing major cardiovascular events. Market
Measures/Corzint officials said the jury appears still to be out, as the controversial
ALLHAT results run counter to those of other major trials that found that ACE
inhibitors are superior to diuretics Diuretics
are already the most frequently-used class of hypertensive drug as the survey
found them to be prescribed either alone or in conjunction with other drugs by
98 percent of the physicians who responded. Market
Measures/Corzint said the low-cost of diuretics may figure into their popularity
particularly among elderly patients, even though generic versions of ACE inhibitors
are available that enables them to compete with diuretics on the cost front. The
survey also reported a growing trend toward physicians prescribing more than one
drug against hypertension across all levels of severity. Physicians are also more
likely to add another drug to a failed first-line therapy than switching to another
drug or class of drugs. "Prescribing patterns could change, with
diuretic usage realizing gains at the expense of ACE inhibitors and calcium channel
blockers, if the ALLHAT findings are adopted in the new Joint National Committee
on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure,"
said Elizabeth Rountree, Executive Vice President at Market Measures/Cozint. Other
