A Study to Assess Maternal and Fetal Outcomes After Taking Prucalopride During Pregnancy

This study will collect information on pregnant women diagnosed with constipation from the two large health care insurance claims records. It will include the following groups: * Those who took prucalopride. * Those who took other medicines for constipation. * Those who did not take any prescription medicines for constipation. The main aim of the study is to find out whether the medicine prucalopride, which is used to treat constipation, is safe for use during pregnancy and to look at whether taking prucalopride at certain times during pregnancy is associated to a higher chance of specific health problems for the mother or baby. The study uses two large existing healthcare insurance databases for collecting information. Participants are not enrolled, treated, or required to visit the doctor during this study.

Inclusion Criteria: * Pregnant women aged 18 to 44 years with constipation. * Maternal coverage by health care and prescriptions insurance during eligibility period: a) To study pregnancy outcomes (live births, spontaneous abortions, terminations, or stillbirths): 90 days prior to the LMP until end of pregnancy; and b) to study malformations, perinatal, and infant outcomes: 90 days to LMP until 30 days post-delivery. * For infant outcomes, the cohort will be restricted to pregnancies with linked offspring. * For major malformations, only pregnancies with livebirths will be included, since information regarding the pathology results from a pregnancy loss or the indication for termination is rarely recorded. In addition, infants are required to have full insurance coverage from delivery to at least 90 days after the delivery, unless the infant died prior to the end of the 90 days, in which case a shorter eligibility period until death is permitted. * For the analyses of pregnancy losses, the cohort also includes pregnancies ending in spontaneous abortion, terminations, stillbirth and any livebirth (linked or unlinked to a delivery). Exclusion Criteria: * Women with opioids dispensed in the 90 days prior to LMP or during the first trimester (to exclude potential opioid-induced constipation). * Women with inflammatory bowel diseases (IBDs) identified based on ICD codes recorded in the 90 days prior to LMP or during the first trimester (because it is a contraindication). * For major malformations, pregnancies with outpatient exposure to definite teratogens including warfarin, valproate, antineoplastic agents, colchicine, testosterone, radioiodine, isotretinoin, misoprostol, and thalidomide from LMP through LMP plus 90 days.
