Application
Flumethasone pivalate is a topical difluorinated corticosteroid ester with anti-inflammatory, antipruritic and vasoconstrictive properties. A prompt decrease in inflammation, exudation and itching is experienced after application. It is commonly used in veterinary practice and has been used in cortisol assays to study early porcine conceptus development.
Biochem/physiol Actions
Flumethasone is a glucocorticoid receptor agonist used in studies on plasma transcortin binding. It binds to the nucleus causing a variety of genetic activation and repressions. The anti-inflammatory actions of flumethasone is thought to involve lipocortins and phospholipase A2 inhibitory proteins, which results in the inhibition of arachidonic acid and the control of prostaglandin and leukotriene biosynthesis. Flumethasone suppresses the immune system due to a decrease in the function of the lymphatic system, a reduction in immunoglobulin and complement concentrations, the precipitation of lymphocytopenia, and interference with antigen-antibody binding .

Dexamethasone is a synthetic glucocorticoid with potent anti-inflammatory properties. However, its administration causes significant side effects, specially in long-term therapy. A new approach for limiting adverse effects consists in the slow and constant deliver of this drug, using dexamethasone-21-phosphate-loaded erythrocytes

Rapid, nongenomic actions of glucocorticoids (GCs) have been well documented, but information about putative membrane receptors that mediate them is scarce. We used fluorescence correlation spectroscopy to search for membrane GC-binding on the mouse pituitary cell line AtT-20. A slowly

The clinical treatment of sudden sensorineural hearing loss currently relies on the administration of steroids, either systemically or via intratympanic injections. Intratympanic injections bypass the hemato-cochlear barrier, reducing its systemic side effects. The efficacy of the injections is limited through
