Abstract

The recent expansion of electronic health and medical record systems may present an opportunity to generate robust post-approval safety data and obviate the limitations of prospective pregnancy exposure registries. We examined and compared, over the same time frame, the outcomes of triptan exposure in pregnancy using (1) a retrospective claims database and (2) a previously completed pregnancy registry. Using the Marketscan database, the risk of major birth defects was ascertained in live-born infants whose birth mothers were exposed to sumatriptan, naratriptan, or sumatriptan/naproxen during pregnancy. The frequencies of outcomes observed were compared with the findings of the 16-year sumatriptan, naratripan, and sumatriptan/naproxen prospective pregnancy registry. About 5120 pregnancies were identified in the retrospective claims cohort in contrast to 617 included in the prospective registry during the same time frame. The proportion of major birth defects among first-semester sumatriptan exposures was 4.0%, which is exactly the same as the proportion of major birth defects reported for first-semester sumatriptan exposures in the registry. There were very few non-livebirth outcomes in both the claims analyses and registry. The...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
