Dosing
Hypovolemic Shock Infants and young children: 2.5 to 5 mL per kg body weight IV; older children and adults: initial dose 100 to 200 mL IV, repeated after 15 to 30 minutes if response is inadequate. Do not exceed 1 mL/min in patients with normal blood volume.
Hypoalbuminemia Calculate body albumin compartment to be 80 to 100 mL per kg body weight; do not exceed a daily dose of 2 g of albumin per kg of body weight, administered IV.
Burns Dose determined by patient's condition and response to treatment after the first 24 hours, administered IV.
Erythroblastosis, Fetal 1 g per kilogram body weight IV prior to or during exchange transfusion.
All indications Initial dose 5-60 mg once daily with food; RAYOS releases active substance approximately 4 hours after intake. Titrate to lowest effective maintenance dose; withdraw gradually after long-term or high-dose therapy.
Contraindications
- History of hypersensitivity reaction to albumin preparations or to any excipient (N-acetyltryptophan and sodium caprylate)
- Severe anemia or cardiac failure with normal or increased intravascular volume
- Known hypersensitivity to prednisone or any excipient
Adverse Reactions
Serious Hypersensitivity reaction, anaphylactic reaction, pulmonary edema
Postmarketing Anaphylactic shock, anaphylactic reaction, hypersensitivity/allergic reactions, headache, dysgeusia, myocardial infarction, atrial fibrillation, tachycardia, hypotension, flushing, pulmonary edema, dyspnea, vomiting, nausea, urticaria, rash, pruritus, pyrexia, chills
Most common Fluid retention, altered glucose tolerance, elevated blood pressure, behavioral and mood changes, increased appetite and weight gain
Serious Anaphylaxis, cardiac arrest, circulatory collapse, congestive heart failure, myocardial rupture, pulmonary edema, peptic ulcer with perforation and hemorrhage, osteonecrosis, pathologic fracture, adrenocortical insufficiency, convulsions, increased intracranial pressure
Postmarketing No new safety concerns identified beyond those established for immediate-release prednisone
Pharmacology
Human albumin accounts for 70 to 80% of the colloid osmotic pressure of normal plasma and serves as a transport protein; administered as a 25% IV solution, it draws approximately 3.5 times its volume of additional fluid into the circulation within 15 minutes, expanding blood volume.
Prednisone is a synthetic corticosteroid with potent anti-inflammatory and immunosuppressive properties that suppresses inflammatory processes (edema, capillary dilatation, leukocyte migration), modifies immune responses, and produces metabolic effects including promotion of gluconeogenesis, protein catabolism, and altered calcium and electrolyte balance.
