Albumin:

MEDICATION SAFETY ISSUES
Sound-alike/look-alike issues:
Albutein® may be confused with albuterol
Buminate® may be confused with bumetanide

U.S. BRAND NAMES — Albumarc®; Albuminar®; AlbuRx™ ; Albutein®; Buminate®; Flexbumin; Plasbumin®

PHARMACOLOGIC CATEGORY
Blood Product Derivative
Plasma Volume Expander, Colloid

DOSING: ADULTS
Note: Use 5% solution in hypovolemic patients or intravascularly-depleted patients. Use 25% solution in patients in whom fluid and sodium intake is restricted.

Usual dose: 25 g; initial dose may be repeated in 15-30 minutes if response is inadequate; no more than 250 g should be administered within 48 hours.

Hypoproteinemia: I.V.: 0.5-1 g/kg/dose; repeat every 1-2 days as calculated to replace ongoing losses.

Hypovolemia: 5% albumin: 0.5-1 g/kg/dose; repeat as needed. Note: May be considered after inadequate response to crystalloid therapy and when nonprotein colloids are contraindicated. The volume administered and the speed of infusion should be adapted to individual response.

DOSING: PEDIATRIC

(For additional information see "Albumin: Pediatric drug information")
Note:5% should be used in hypovolemic patients or intravascularly-depleted patients. 25% should be used in patients in whom fluid and sodium intake must be minimized.

Dose depends on condition of patient: Hypovolemia: I.V.: 0.5-1 g/kg/dose (10-20 mL/kg/dose of albumin 5%); maximum dose: 6 g/kg/day

DOSING: ELDERLY — Refer to adult dosing.

GENERIC EQUIVALENT AVAILABLE — Yes

ADMINISTRATION — For I.V. administration only. Use within 4 hours after opening vial; discard unused portion. In emergencies, may administer as rapidly as necessary to improve clinical condition. After initial volume replacement:
5%: Do not exceed 2-4 mL/minute in patients with normal plasma volume; 5-10 mL/minute in patients with hypoproteinemia
25%: Do not exceed 1 mL/minute in patients with normal plasma volume; 2-3 mL/minute in patients with hypoproteinemia

Do not dilute 5% solution. Rapid infusion may cause vascular overload. Albumin 25% may be given undiluted or diluted in normal saline. May give in combination or through the same administration set as saline or carbohydrates. Do not use with ethanol or protein hydrolysates, precipitation may form.

COMPATIBILITY — Stable in dextran 6% in D5W, dextran 6% in NS, D5LR, D5NS, D51/2NS, D51/4NS, D5W, D10W, LR, NS, 1/2NS; incompatible with sterile water.

Y-site administration: Compatible: Diltiazem, lorazepam. Incompatible: Midazolam, vancomycin, verapamil.

USE — Plasma volume expansion and maintenance of cardiac output in the treatment of certain types of shock or impending shock; may be useful for burn patients, ARDS, and cardiopulmonary bypass; other uses considered by some investigators (but not proven) are retroperitoneal surgery, peritonitis, and ascites; unless the condition responsible for hypoproteinemia can be corrected, albumin can provide only symptomatic relief or supportive treatment

CONTRAINDICATIONS — Hypersensitivity to albumin or any component of the formulation; patients with severe anemia or cardiac failure

WARNINGS / PRECAUTIONS
Concerns related to adverse effects: Hypervolemia: All patients should be observed for signs of hypervolemia such as pulmonary edema; monitor closely with rapid infusions.

Disease-related concerns: Hepatic impairment: Use with caution in patients with hepatic impairment; protein load may exacerbate or precipitate encephalopathy. Renal impairment: Use with caution in patients with renal impairment; protein load may precipitate azotemia.

Special populations: Preterm infants: Avoid 25% concentration in preterm infants due to risk of intraventricular hemorrhage. Sodium restricted patients: Use with caution in those patients for whom sodium restriction is necessary.

Other warnings/precautions: Nutritional supplementation: Is not an appropriate indication for albumin.
