A pilot study on in-utero exposure to psychotropic drugs: A comparison of pharmacological classes on neonatal and maternal outcomes.

Objective: In this retrospective cohort study, we compared neonatal and maternal outcomes after exposure of different psychopharmacological classes of drugs. Both psychiatric diseases and pharmacological treatment of these are associated with lower birth weights, lower APGAR scores, and NICU admission. Therefore, we tried to rule out the role of psychotropics as if no differences were found between pharmacological classes, the lower birthweights might not be attributable to these.
Method: We divided our groups in exposed to atypical antipsychotic drugs, Selective Serotonin Reuptake Inhibitors (SSRI), Tricyclic Antidepressants (TCA), benzodiazepines, and different combinations of psychotropic drugs. The last group included SSRIs combined with benzodiazepines, methylphenidate, lithium, and classic antipsychotic drugs.
Results: We used univariate regression analysis to see which factors from our rich dataset including pharmacological class, are associated with birth weight, APGAR scores, gestational age, and NICU admission. The significant associations from univariate analyses were further analyzed using ancova analysis or logistic regression where applicable.
Conclusion: We found no clinically relevant differences in neonatal and maternal outcomes between the different exposed pharmacological classes. However, our dataset may have been too small to draw firm conclusions.
