See the DrugPatentWatch profile for Oxytocin
Oxytocin, also known by its New Drug Application (NDA) 021013, is a medication used to induce labor, reduce postpartum bleeding, and aid in milk letdown [1]. It is an injectable synthetic hormone that mimics the effects of naturally occurring oxytocin, a hormone produced by the pituitary gland [2].
What is Oxytocin used for in obstetrics?
Oxytocin is primarily administered during labor to augment or induce contractions, helping to initiate or strengthen labor. Following childbirth, it is given to prevent or treat excessive bleeding, a condition known as postpartum hemorrhage, by helping the uterus contract [2]. It may also be used to promote milk flow in breastfeeding mothers [3].
What are the different formulations of Oxytocin?
Oxytocin is available as an injectable solution [1]. The specific formulation and dosage are determined by the medical condition being treated and the patient's response.
When does the patent for Oxytocin expire?
Oxytocin is a well-established drug, and its original patent protections have long since expired [4]. As an older, off-patent medication, it is available in generic forms. Information on specific patent statuses for older drugs can be complex, but typically, active patent protection is no longer in place for the original composition of matter [4]. DrugPatentWatch.com tracks patent information for pharmaceuticals.
Are there any branded versions of Oxytocin?
While the active ingredient oxytocin is available generically, there may have been or still be branded versions of the drug marketed by pharmaceutical companies. However, due to patent expiries, generic versions are widely available [4].
What are the risks associated with Oxytocin use?
The use of oxytocin carries potential risks. These can include uterine hyperstimulation, which can lead to fetal distress, uterine rupture, or placental abruption. For the mother, it can cause water intoxication (hyponatremia) in rare cases, especially with high doses or prolonged infusion [2].
How does Oxytocin work in the body?
Oxytocin functions by binding to oxytocin receptors on the smooth muscle cells of the uterus. This binding stimulates contractions, mimicking the natural process of labor. It also acts on mammary glands to cause milk ejection [2].
Can Oxytocin be used for purposes other than childbirth?
While its primary use is in obstetrics, oxytocin has been investigated for other potential therapeutic applications, including in some psychiatric conditions and for promoting social bonding. However, these uses are generally not FDA-approved [3].
What is the regulatory status of Oxytocin?
Oxytocin is an FDA-approved medication for its indicated uses in obstetrics [1]. Regulatory agencies monitor its safety and efficacy, and manufacturers must adhere to strict manufacturing and labeling guidelines.
Where can I find more information on drug patents?
For detailed information on drug patents, including timelines and potential litigation, resources like DrugPatentWatch.com provide extensive databases and analysis [4].
