Stock solutions are most stable when stored in aliquots at -20°C, protected from light. Solutions are expected to remain stable for 2 - 4 weeks when refrigerated at 2-8°C. The stability of this product in solution at room temperature has not been evaluated. Commercially available products, such as Solu Cortef® solutions, stored at room temperature at >2 mg/mL, are recommended to be discarded after 3 days or sooner if a change in color or turbidity is noted.

Biochem/physiol Actions
Hydrocortisone (also referred to as cortisol) is an endogenous glucocorticoid which is secreted by the adrenal gland. It is produced from the hypothalamus–pituitary–adrenal (HPA) axis. Hydrocortisone interacts with glucocorticoid receptors and regulates various signaling pathways. It is associated with the induction of energy mobilization, increase in cerebral perfusion rates and local glucose consumption. It is also linked with increase in cardiovascular output and respiration, redistribution of blood, delivery of molecules and energy to the brain and muscles and modulation of immune responses.[3][4]
Primary glucocorticoid secreted by the adrenal cortex.
Primary glucocorticoid secreted by the adrenal cortex. It has three times the anti-inflammatory potency of corticosterone but much lower Na2+ retention potency.

How stable is hydrocortisone? I use it and supplement a medium but I administer it every 48 hours, can I have my stock for 7 days and it does not lose its effect or do I have to defrost it every time I use it so that it does not lose its effect?
1 answer-
The stability of this product in solution has not been determined. To assure optimum performance, it is recommended that solutions be stored in frozen aliquots at -20°C. However, the water soluble version of Hydrocortisone, available as product H0396, is estimated to be stable for 1 - 2 weeks when refrigerated at 2 - 8°C. Note that a publication, J. AM. PHARM. ASSOC., 49, 253 (1960), determined that solutions prepared in ethanol at 40mg/mL and stored at 25°C decline by 50% in potency after 160 days.

Can it be dissolved completely in absolute ethanol, and stored per instructions (instead of 1:1 chloroform and ethanol)?
1 answer-
A stock solution can be prepared by reconstituting the product at 1 mg/ml in 100% EtOH. Gently swirl to dissolve. Then dilute to 50 ug/ml with sterile culture media, aliquot, and store at -20 °C. As a frozen aliquot, this should be stable for at least 3-4 months. Avoid the freeze/thaw cycle.
