Uterotonic
（重定向自Oxytocic）
A uterotonic, also known as ecbolic, is an agent used to induce contraction or greater tonicity of the uterus. Uterotonics are used both to induce labor, and to reduce postpartum hemorrhage.
Some uterotonics act as analogues of oxytocin. An oxytocinergic, or oxytocic, means "having to do with oxytocin (OXT)". The Oxytocin Receptor (OXTR) is the binding and activation site of oxytocin.
