Pharmacological treatment of pregnancy complications in adults: An overview of phase IV clinical trials.

The aim of this review was to provide a review of the pharmacological treatments for pregnancy complications in adults. This review analyzed medications used for pregnancy complications in phase IV clinical trials based on the ClinicalTrials.gov database. The search included completed trials only. As of September 1, 2023, a total of 29,654 phase IV clinical trials were identified, of which 298 were related to pregnancy complications. Of these, 24 clinical trials met the inclusion criteria for the current study. In the 24 included clinical trials, we found 9 trials for overactive bladder with 5005 participants in total, 236 of which had adverse effects from the drugs used. Six trials for preeclampsia were conducted on 663 participants, with only 1 adverse drug effect reported. Three trials each were conducted on urinary tract infections and gestational diabetes mellitus (115 and 656 participants, respectively) without any adverse drug effects reported. One trial each focused on anemia, dystocia, and placentation disorders (80, 1003, and 14 participants, respectively) without any adverse drug effects reported. The trials reported minimal adverse drug effects, suggesting potential effectiveness and safety in managing these complications. While the trials mentioned minimal adverse effects, close monitoring and individualized patient care are essential, as are evaluating the risk-benefit ratio and the specific circumstances of each patient.
