Why is oxytocin stored in fridge?
Consequently, WHO and UNICEF have jointly recommended that all oxytocin products are supplied and stored under refrigerated conditions to avoid product deterioration in countries where ambient temperatures exceed 25°C.
Where oxytocin is stored?
Oxytocin is produced in the hypothalamus and is secreted into the bloodstream by the posterior pituitary gland. Secretion depends on electrical activity of neurons in the hypothalamus – it is released into the blood when these cells are excited.
Can you freeze oxytocin?
Researchers found that oxytocin concentrations in ampules remained stable after exposure to freezing temperatures. These results should reassure health care workers and skilled birth attendants that oxytocin ampules can be safely used even if temporarily frozen during transportation or storage.
What is shelf life of oxytocin?
Oxytocin parenteral solutions in the final concentration of 0.02 U/mL and diluted in normal saline are stable for at least 30 days under frozen and refrigerated conditions for 30 days.
Can oxytocin be stored at room temperature?
Depending upon the manufacturer, oxytocin products should be stored at either controlled room temperature (25°C or less) or in refrigerated storage (2°- 8°C) in order to ensure quality and comply with the labelled storage conditions.
How is oxytocin stored?
In the hypothalamus, oxytocin is made in magnocellular neurosecretory cells of the supraoptic and paraventricular nuclei, and is stored in Herring bodies at the axon terminals in the posterior pituitary. It is then released into the blood from the posterior lobe (neurohypophysis) of the pituitary gland.
How is oxytocin injection stored?
Does oxytocin degrade?
The degradation of oxytocin as a function of concentration was tested at 70°C for oxytocin formulated at 0.02 mg/ml, 0.1 mg/ml and 0.5 mg/ml over the pH range of 2.0 to 9.0. However, for oxytocin formulations of pH 4.5, 7.0 and 9.0 the degradation rates increased with the concentration.
What is expiry date of medicine?
What does the ‘expiry date’ mean? The expiry date usually means that you should not take the medicine after the end of the month given. For example, if the expiry date is July 2020, you should not take the medicine after 31 July 2020.
How do you calculate the expiry date of a drug?
The expiration date of a drug is estimated using stability testing under good manufacturing practices as determined by the Food and Drug Administration (FDA). Drug products marketed in the US typically have an expiration date that extends from 12 to 60 months from the time of manufacturer.
Should oxytocin be kept in fridge?
Which is the best temperature to store oxytocin?
Differences in labelled storage requirements can lead to uncertainties among stakeholders around the relative stability of oxytocin products and specifically whether ≤25°C products are more resistant to degradation.
Is the injection of oxytocin recommended by who?
Introduction Oxytocin, administered via injection, is recommended by WHO for the prevention and treatment of postpartum haemorrhage. However, the susceptibility of oxytocin injection to thermal degradation has led WHO and UNICEF to recommend cold-chain storage of all oxytocin products.
How long do oxytocin ampoules last in refrigeration?
Visualisation of the oxytocin temperature cycling study. One cycle consisted of ampoule storage at either 30°C, 40°C or 50°C for a 30-day period then a refrigeration period for 15 days. This cycle was undertaken three times, for a total study duration of 135 days.
What happens to the body after an oxytocin injection?
Severe hypertension has been reported when oxytocin was given three to four hours following prophylactic administration of a vasoconstrictor in conjunction with caudal block anesthesia. Cyclopropane anesthesia may modify oxytocin’s cardiovascular effects, so as to produce unexpected results such as hypotension.
