Combinational Tocolysis: Evaluating Lower-Dose Combinations of Nifedipine, Indomethacin and Aminophylline for Tocolytic Synergism in Pregnant Human Myometrium

The authors aimed to determine whether lower-dose combinations of the tocolytics nifedipine, indomethacin, and aminophylline could produce synergistic effects in inhibiting contractions of pregnant human myometrial tissue. Their findings revealed that dual combinations of nifedipine with either indomethacin or aminophylline, as well as the triple combination of all three drugs, demonstrated significant synergism, suggesting that these combinations could enhance tocolytic efficacy while minimizing side effects. This study supports the potential for further clinical investigation into combinational tocolysis to improve outcomes in preterm birth management.
