Abstract

Purpose: Hyperemesis gravidarum is the third leading cause of hospitalization during pregnancy. 5-HT3-receptor antagonists are the most effective against chemotherapy-induced nausea and vomiting and radiation. This randomized study aimed to compare and evaluate the efficacies of granisetron and promethazine for controlling nausea and vomiting of pregnancy.

Methods: The included patients were administered (oral and intravenous) granisetron and promethazine randomly. The patients were evaluated for nausea and vomiting by a senior gynecology resident blinded to designated drugs.

Results: This study revealed that granisetron significantly decreased nausea and vomiting in pregnant women (p < 0.05). Greater patient satisfaction and lesser adverse drug reactions in women receiving granisetron observed in this study suggest that it can be introduced as a more effective and safer drug in comparison with promethazine.

Conclusions: Considering the prevalence of nausea and vomiting of pregnancy and hyperemesis gravidarum, we can state that it is a health-related problem with economic, social and psychological dimensions. All efforts especially simple outpatient strategies to reduce its severity will help the pregnant woman continue her pregnancy with more satisfaction.
