Effect of BPJ, nifedipine, and the combination of BPJ with nifedipine on human myometrial contractility in vitro. BPJ (green; 15 μL), nifedipine (violet; 5 μL of 3.7 μg/mL), or their combination (orange, same concentrations) were added to the myograph chamber. The scatter dot plot shows the AUC (a), the amplitude (b), and the frequency (c) expressed as percentage of initial. Krebs solution was used as negative control (black, 5 μL). Data were obtained from 11 to 13 different biopsies (n = 11–13) and are presented as mean value ± SEM. *p < 0.05
