In the past several years, some newer medications have come on the market; these are commonly referred to as COX-2 inhibitors . Remember, all NSAIDs work against cyclooxygenase (COX). Traditional NSAIDs (. Ibuprofen, Motrin, Aleve) work against both COX-1 and COX-2. COX-1 and COX-2 are both types of cyclooxygenase enzymes that function in your body. The new medications (. Celebrex) work primarily against COX-2, and allow COX-1 to function normally. Because COX-1 is more important in producing the protective lining in your gut (gastric mucosa), these newer NSAIDs are believed to have less of a risk of causing stomach ulcers.
NSAIDs are not recommended during pregnancy, particularly during the third trimester . While NSAIDs as a class are not direct teratogens , they may cause premature closure of the fetal ductus arteriosus and kidney ADRs in the fetus. Additionally, they are linked with premature birth  and miscarriage .   Aspirin, however, is used together with heparin in pregnant women with antiphospholipid antibodies .  Additionally, indomethacin is used in pregnancy to treat polyhydramnios by reducing fetal urine production via inhibiting fetal kidney blood flow.
