Intraperitoneal administration of 2,5-dimethylpyrazine (2,5-DMP) was found to inhibit oxytocin- and prostaglandin F2alpha-induced tetanic uterine contractions in normal or pregnant female rats. This suggests that 2,5-DMP may be used as a countercontraction agent or relaxant for preventing oxytocic agent-induced medical
