BMD Changes With BP-lowering Drugs

Studying the effects of various therapies

Thiazide diuretic (THZD) users had a slower decline in bone mineral density (BMD) compared to nonusers, while decline among ACE inhibitor (ACEi) and beta blocker (BB) users were similar to rates in nonusers, according to a study of 2,312 women, including 69 ACEi, 71 BB, and 74 THZD users. Researchers found:

• THZD users had a statistically insignificant slower rate of BMD decline in the femoral neck and spine.

• Annual percentage changes in BMD among ACEi and BB users were similar to rates in nonusers.

• Compared to BB, THZD use was associated with a trend toward less annual BMD loss at the spine and a similar trend at the femoral neck.

• Compared to ACEi, THZD use was associated with less loss at the femoral neck, but not at the spine.
