dexamethasone contraindications prednisolone

So if you were replacing 10 mg of hydrocortisone with dexamethasone, the equivalent dose would need to be 0.125 mg. Experimental animal studies on dexamethasone have revealed it possesses greater anti-inflammatory activity than many steroids. Continuous treatment for over 10 days can produce adrenal suppression for 3-4 weeks.

Binding to plasma proteins is less than for hydrocortisone and prednisolone. So if you were replacing 10 mg of hydrocortisone with dexamethasone, the equivalent dose would need to be 0.125 mg. For prednisolone in comparison, the equivalence factor is 4 (2.5 mg prednisolone equates to 10 mg hydrocortisone).
Contraindications : Use in preterm infants may be associated with an increased risk of cerebral palsy. There is the general choice between long-acting preparations (in a depot vehicle) and shorter-acting soluble preparations. The duration of action is even longer, lasting approximately 36–54 hours, so there is the potential for overlapping effects on a twice daily dosing schedule hence the high incidence of side effects with dexamethasone. Systemic fungal infections, cerebral malaria, tuberculosis disease of eye. Our own preference has been the use of prednisolone formulations for severe intraocular inflammatory disease. Common adverse effects of dexamethasone include fluid retention, dyspepsia, hyperglycemia, and mood changes (Osmotic agents have been shown to reduce cerebral edema and improve brain perfusion. Dexamethasone is a potent, long-acting glucocorticoid, which is commonly applied topically to the eye to treat eye inflammation caused by, for example, injury, surgery, or infections.VTD has been compared with TD in a randomized trial.Although 8 mg is the most commonly used dose for prevention of PONV, dose-response studies suggest that 5 mg is the minimum effective dose for PONV prophylaxis (Dexamethasone is an effective and well-tolerated component of antiemetic combination therapy.Many steroid preparations are now available. To date this route of administration has been achieved using three approaches.

In a study of HAPE-susceptible individuals ascending to 4559 m, dexamethasone has been shown to decrease pulmonary artery pressure and prevent HAPE. The mechanism underlying this finding is indistinct but might be associated to its effects on sympathetic activity, pulmonary capillary permeability, epithelial sodium transport, endothelial nitric oxide synthetase activity, and availability of nitric oxide (Dexamethasone might have a role in HAPE treatment considering its potential role in HAPE prevention, and studies demonstrating effects on maximum exercise capacity, pulmonary inflammation, and ion-transporter function in hypoxia. Although studies do show differences in corneal penetration between phosphate and acetate preparations of steroids, we have not noted a major difference in efficacy between the two preparations for treating active inflammation. We frequently ask the patient to administer his or her drops every hour while awake. Find out what health conditions may be a health risk when taken with Dexamethasone Oral The bioavailability is 90% similar to prednisolone and hydrocortisone.Although its role in AMS prevention has been established in research studies and clinical experience, the mechanism by which it plays this role remains unexplained. The biological half-life of dexamethasone is approximately 190 minutes which is almost twice as long as hydrocortisone. Status asthmaticus is a contraindication for inhalative glucocorticoids. The schedule for tapering is unique to each patient, but persons who have had numerous attacks may need to receive one or two drops a day for weeks or even months.A second option is to inject the corticosteroid periocularly.
