Study on the safety of perinatal medication

Research output: Contribution to journalReview articlepeer-review

Abstract

We have been conducting research with the aim of generating evidence for the safety of perinatal drugs. As a result of reviewing the records of inquiries to the Drug Information Office of our hospital, we found a large discrepancy between the description of perinatal drugs in package inserts in Japan and the description of the Pregnancy Risk Category according to the U.S. Food and Drug Administration. In the Japan Environment and Children's Study (JECS), we determined the proportion of drug and supplement use among 97464 pregnant women. We clarified that prescriptions of antihypertensive drugs for pregnant women increased during the second half of pregnancy, while prescriptions of anti-epileptic and anti-anxiety drugs decreased after pregnancy using a claims database. A survey of pharmacists and pharmacy students revealed a lack of awareness of eŠective folic acid intake to reduce the risk of neural tube defects in infants. The percentage of pre-pregnancy folic acid supplementation among pregnant women participating in the Babies and their Parents' Longitudinal Observation in Suzuki Memorial Hospital on Intrauterine Period (BOSHI) study, the JECS, and the Tohoku Medical Megabank (TMM) Birth and Three-Generation (BirThree) cohort study was 6.3-18.0%. As a result of close examination of the records of inquiries to the Drug Information Office of our hospital, and of cases in which our lactation plan sheet was applied, it was found that there were discrepancies between the information on the drug package insert and the information on Medications & Mother's Milk, etc. in Japan. The results obtained have been clinically applied in daily practice and we are continuing our research while taking measures.
