Drug Guide
Sargramostim
Classification
Therapeutic: Hematopoietic growth factor
Pharmacological: Granulocyte-macrophage colony-stimulating factor (GM-CSF)
FDA Approved Indications
- Neutropenia post-hematopoietic stem cell transplant
- Neutropenia induced by chemotherapy in acute myeloid leukemia (AML) patients
- Autologous marrow transplantation to shorten neutropenia
Mechanism of Action
Stimulates proliferation and differentiation of granulocyte and macrophage progenitor cells by binding to GM-CSF receptors, enhancing hematopoiesis.
Dosage and Administration
Adult: Based on indication; generally, 250 mcg/m2/day subcutaneously or intravenously, adjusted according to clinical response.
Pediatric: Dosage varies; consult specific protocols depending on condition and weight.
Geriatric: No specific adjustments, but caution due to potential comorbidities.
Renal Impairment: Adjust dosage based on clinical response and tolerability.
Hepatic Impairment: No specific adjustments established.
Pharmacokinetics
Absorption: Subcutaneous and intravenous administration; rapid onset.
Distribution: Distributed in plasma and tissues; crosses biological membranes.
Metabolism: Metabolized and cleared primarily via renal pathways.
Excretion: Renal excretion of metabolites.
Half Life: Approx. 2-4 hours in plasma.
Contraindications
- Hypersensitivity to Sargramostim or other GM-CSF products.
Precautions
- Use with caution in patients with bone marrow disorders, or those at risk for leukemic proliferation. Avoid in patients with eosinophilia, pulmonary infiltrates, or active infections.
Adverse Reactions - Common
- Bone pain (Frequent)
- Fever, chills (Often)
- Malaise, fatigue (Common)
Adverse Reactions - Serious
- Capillary leak syndrome (Rare)
- Severe allergic reactions including anaphylaxis (Rare)
- Progression of leukemia or other malignancies (Rare)
Drug-Drug Interactions
- Chemotherapy agents that suppress marrow
Drug-Food Interactions
N/ADrug-Herb Interactions
N/ANursing Implications
Assessment: Monitor complete blood counts regularly to assess hematopoietic response. Observe for signs of allergic reactions.
Diagnoses:
- Risk for infection due to neutropenia
- Impaired skin integrity
Implementation: Administer as ordered, preferably subcutaneously. Evaluate for side effects and response.
Evaluation: Assess for improvement in neutrophil counts and resolution of clinical symptoms. Watch for adverse effects.
Patient/Family Teaching
- Report any fever, chills, or signs of allergic reaction immediately.
- Maintain good hygiene to reduce infection risk.
- Understand the purpose of the medication and comply with dosing schedules.
Special Considerations
Black Box Warnings:
- Potential for leukemic transformation or other hematologic malignancies (monitor closely).
Genetic Factors: N/A
Lab Test Interference: May elevate baseline white cell counts, complicating interpretation.
Overdose Management
Signs/Symptoms: Severe leukocytosis, capillary leak syndrome.
Treatment: Discontinue drug, provide supportive care, and monitor hematologic status.
Storage and Handling
Storage: Store refrigerated at 2-8°C (36-46°F). Protect from light.
Stability: Stable for up to 3 months when refrigerated.
