Which category are ACE inhibitors classified as for pregnant women in their second or third trimester?

1. Category A

2. Category B

3. Category C

4. Category D

The correct answer is: Category D

ACE inhibitors are classified as Category D for pregnant women in their second and third trimesters. Category A drugs are considered the safest as they have been tested and found to have no adverse effects on the fetus, but this testing is not typically done in pregnant women due to ethical concerns. Category B drugs have not been shown to cause harm in animal studies, but there is limited data on the effects in pregnant women. Category C drugs have been shown to cause harm in animal studies and may also have limited data in pregnant women. Category D drugs have been shown to cause potential harm in human studies and should only be used if the benefits outweigh the risks.
