Medicine Description oxytocin 10i
Oxytocin for Labor Induction & Uterine Contractions is a medication that primarily acts on the myometrial tissue of the uterus. It binds to G-protein coupled receptors, specifically activating Gq and G11 pathways. This interaction leads to the activation of phospholipase C, resulting in the hydrolysis of phosphatidylinositol bisphosphate and the subsequent production of inositol triphosphate (IP3) and diacylglycerol (DAG). The increase in IP3 levels stimulates the release of calcium ions from intracellular stores, which, along with calcium influx through voltage-gated calcium channels, promotes uterine muscle contraction. Furthermore, oxytocin's role in enhancing prostaglandin synthesis contributes to uterine contractility, facilitating labor progression and reducing postpartum hemorrhage.
Indications and Uses of Oxytocin for Labor Induction & Uterine Contractions
- Induction of labor
- Augmentation of labor
- Management of postpartum hemorrhage
- Assessment of fetal well-being through the oxytocin challenge test
Side Effects of Oxytocin for Labor Induction & Uterine Contractions
- Uterine hyperstimulation
- Maternal hypotension
- Headaches
- Nausea and vomiting
- Cardiac arrhythmias
- Water intoxication leading to hyponatremia
Storage and Handling
Oxytocin should be stored at room temperature, away from light. It should not be frozen and must be kept out of reach of children. Once opened, any unused portion should be discarded after a specified period as per pharmacy guidelines.
Patient Advice and Precautions
Patients should be monitored closely for uterine contractions and maternal vital signs during oxytocin administration. Be aware of the signs of uterine hyperstimulation, which may necessitate discontinuation of the medication. It's important to counsel patients about the potential side effects and to report any concerning symptoms immediately.
