Synthetic oxytocin, sold under the brand name Pitocin among others, is a medication made from the peptide oxytocin. [ 6 ] [ 7 ] As a medication, it is used to cause contraction of the uterus to start labor , increase the speed of labor , and to stop bleeding following delivery . [ 6 ]
Oxytocin is a peptide hormone and neuropeptide normally produced in the hypothalamus and released by the posterior pituitary. [4] Present in animals since early stages of evolution, in humans it plays roles in behavior that include social bonding, love, reproduction, childbirth, and the period after childbirth.
The oxytocin receptor, also known as OXTR, is a protein which functions as receptor for the hormone and neurotransmitter oxytocin. [4] [5] In humans, the oxytocin receptor is encoded by the OXTR gene [6] [7] which has been localized to human chromosome 3p25. [8] Evolutionary tree of the oxytocin, vasotocin, mesotocin and isotocin receptors and ...
Oxytocin/ergometrine (trade name Syntometrine) is an obstetric combination drug. The components are synthetically produced oxytocin , a human hormone produced in the hypothalamus , and ergometrine , an alpha-adrenergic , dopaminergic and serotonin (5-HT 2 ) receptor agonist.
The action of drugs on the human body (or any other organism's body) is called pharmacodynamics, and the body's response to drugs is called pharmacokinetics. The drugs that enter an individual tend to stimulate certain receptors, ion channels, act on enzymes or transport proteins. As a result, they cause the human body to react in a specific way.
The medicine is given in a rapid infusion and may cause hypotension. Oxytocin alone is the usually treatment of atony in the US. However, if bleeding is uncontrolled after administration of oxytocin, then a second uterotonic is given. [20] Carbetocin: A synthetic analog of oxytocin, works similarly to oxytocin but the half-life is much longer. [23]
Epelsiban (INN, [1] USAN, [2] code name GSK-557,296-B) is an orally bioavailable drug which acts as a selective and potent oxytocin receptor antagonist (K i = 0.13 nM). [3] [4] It was initially developed by GlaxoSmithKline (GSK) for the treatment of premature ejaculation in men [5] [6] and then as an agent to enhance embryo or blastocyst implantation in women undergoing embryo or blastocyst ...
Prostaglandin E 2 (PGE 2), also known as dinoprostone, is a naturally occurring prostaglandin with oxytocic properties that is used as a medication. [2] [3] [4] Dinoprostone is used in labor induction, bleeding after delivery, termination of pregnancy, and in newborn babies to keep the ductus arteriosus open.
