Pharmacological Index

Immunosuppressant Agent


Use

Prophylaxis of acute organ rejection in patients receiving renal transplants; used as part of an immunosuppressive regimen that includes cyclosporine and corticosteroids


Pregnancy Risk Factor

C


Contraindications

Hypersensitivity to any component of the product


Warnings/Precautions

Only physicians experienced in immunosuppressive therapy and management of organ transplant patients should prescribe daclizumab. Manage patients receiving the drug in facilities equipped and staffed with adequate laboratory and supportive medical resources. Readministration of daclizumab after an initial course of therapy has not been studied in humans. The potential risks of such readministration, specifically those associated with immunosuppression or the occurrence of anaphylaxis/anaphylactoid reactions, are not known.

Miscellaneous: Increased diaphoresis, night sweats, post-traumatic pain


Overdosage/Toxicology

Overdose has not been reported; a maximum tolerated dose has not been determined in patients. A dose of 1.5 mg/kg has been administered to bone marrow transplant recipients without any associated adverse events.


Stability

Refrigerate vials at 2°C to 8°C/36°F to 46°F. Do not shake or freeze; protect undiluted solution against direct sunlight. Dose should be further diluted in 50 mL 0.9% sodium chloride solution. Diluted solution is stable for 24 hours at 4°C or for 4 hours at room temperature.


Mechanism of Action

Inhibits the binding of IL-2 to the high affinity IL-2 receptor, thus suppressing T cell activity against allografts. Its active ingredient, daclizumab, a humanized monoclonal antibody, binds to the alpha subunit of the high affinity interleukin-2 receptor (IL-2R) which is expressed on activated T cells.


Pharmacodynamics/Kinetics

Volume of central compartment: 2.5 L

Volume of peripheral compartment: 3.4 L

Estimated half-life (terminal elimination): 20 days (480 hours)


Usual Dosage

Children and Adults: IVPB: 1 mg/kg, used as part of an immunosuppressive regimen that includes cyclosporine and corticosteroids for a total of 5 doses; give the first dose less than or equal to 24 hours before transplantation. The 4 remaining doses should be administered at intervals of 14 days.


Administration

Daclizumab dose should be diluted in 50 mL NS solution. When mixing the solution, gently invert the bag to avoid foaming; do not shake. Daclizumab solution should be administered within 4 hours of preparation if stored at room temperature; infuse over a 15-minute period via a peripheral or central vein


Mental Health: Effects on Mental Status

May cause depression, anxiety, or insomnia


Mental Health: Effects on Psychiatric Treatment

None reported


Dental Health: Local Anesthetic/Vasoconstrictor Precautions

No information available to require special precautions


Dental Health: Effects on Dental Treatment

No effects or complications reported


Dosage Forms

Injection: 5 mg/mL (5 mL)
