母親自身催產素與點滴給予催產素的異同
How Are They Similar and How Are They Different?
Oxytocin and Pitocin® are identical in chemical structure, which is comprised of a chain of nine amino acids (called a nonapeptide). However, they don’t act on the body in the same way. In addition to causing uterine contractions that help to birth the placenta and prevent PPH, the mother’s oxytocin is also released in the brain, where it reduces anxiety, stress, and pain. This is a major difference between oxytocin and Pitocin®: the birthing person’s own oxytocin levels rise in both blood and brain fluid, but Pitocin® does not cross into the brain because of the blood brain barrier (Meisenberg an Simmons, 1983). Interestingly, researchers are now studying intranasal (nose-to-brain) delivery of synthetic oxytocin as a way of crossing the blood brain barrier and treating different brain diseases (Quintana et al. 2018).
