Oxytocin is a drug used to induce labor during pregnancy. This drug incites uterine contractions that increase all through the pregnancy, achieving the maximum at term by multiplying oxytocin receptors. It also enhances the tone and amplitute of the uterine contractions at smaller dosages. It is known as a peptide hormone and a neuropeptide that is normally produced by the brain for social bonding, sexual reproduction, and childbirth.
