Summary:Nausea and vomiting of pregnancy (NVP) is among the most common conditions that pregnant women encounter in the early stages of pregnancy. It can affect up to 85% of pregnant women, thus representing a significant public health concern. NVP results in substantial negative physical, emotional, and financial consequences. Despite its prevalence, the pathogenesis remains elusive. Few guidelines have been published; however, several interventions exist for the symptomatic treatment of NVP. The aim of this review is to provide an overview of modern treatment strategies of NVP with a special focus on the recently approved dual-release formulation of the doxylamine and pyridoxine combination. This combination was approved by the Food and Drug Administration (FDA) in November 2016 for the treatment of NVP when conservative management fails, and it has been introduced to the American market in April 2018. The maximum plasma concentration (T ) of doxylamine and pyridoxal-5-phosphate is reached 3.5 h and 15 h, respectively, after administration of one tablet twice daily, or 4.5 h and 0.5 h, respectively, when one tablet is administered just once daily. In addition, the delayed-release combination allows sufficient levels of doxylamine and the active metabolite pyridoxal-5-phosphate in the systemic circulation, providing symptoms relief in the subsequent morning. Hence, the dual-release formulation can improve the quality of life of pregnant women suffering from NVP. Additionally, large epidemiological trials have shown no increased risk of adverse effects to newborns, demonstrating that its use is not teratogenic.
