Some of the mostcommonly used medicines for high blood pressure are drugs called ACEin-hibitors.Doctors have given these drugs to patients for twenty-five years.A
government study inthe
Doctors have knownfor years that women should not take ACE inhibitors during the last six monthsof pregnancy.The medicine can injure the baby.ACE
inhibitors,though,havebeen con-sidered safe when taken during the first three months. But a new studyhas found that women who take these drugs early in their pregnancy
still increase therisk of birth disorders. The study shows that,compared to others,their babieswere almost three times as likely to be born with major problems .These
included problemswith the formation of the brain and nervous system and holes in the heart.
The researchers saythey found no increased risk in women who took other blood pressure medicinesduring the first three months.Researchers at
births between 1985and 2000.Two hun-dred nine babies were born to women who took ACE inhibitorsduring the first three months of their pregnancies.Eighteen of the
babies,or almostnine percent,had major disorders.
ACE inhibitors areoften given to patients with diabetes. But diabetes during pregnancy can resultin birth defects.So the study did not include any women known to be
diabetic.ACE inhibi-tors suppress a protein called angiotensin-converting enzyme or ACE.This enzymeproduces a chemical in the body that makes blood passages
narrow.The drugsincrease the flow of blood so pressure is reduced.
New drugs are testedon pregnant animals to see if they might cause birth defects in humans. Butexperts say these tests are not always dependable.The United States Food
and Drug Adminis-tration helped pay for the study .The F. D.A.says women who might becomepregnant should talk with their doctor about other ways to treat high blood
pressure.
