VINORELBINE TARTRATE
| VINORELBINE TARTRATE (vin-o-rel'been) Navelbine Classifications: antineoplastic agent; mitotic inhibitor; Therapeutic: antineoplastic Prototype: Vincristine Pregnancy Category: D |
Availability
10 mg/mL injection
Action
A semisynthetic vinca alkaloid with antineoplastic activity. Inhibits polymerization of tubules into microtubules, which disrupts mitotic spindle formation.
Therapeutic Effect
Arrests mitosis at metaphase, thereby inhibiting cell division in cancer cells.
Uses
Non-small cell lung cancer.
Unlabeled Uses
Breast cancer, ovarian cancer, Hodgkin's disease.
Contraindications
Hypersensitivity to vinorelbine, infection; severe bone marrow suppression; pregnancy (category D), lactation.
Cautious Use
Hypersensitivity to vincristine or vinblastine; leukopenia or other indicator(s) of bone marrow suppression; chickenpox or herpes zoster infection; hepatic insufficiency; pulmonary disease; preexisting neurological or neuromuscular disorders. Safety and efficacy in children are not established.
Route & Dosage
| Non-Small Cell Lung Cancer, Breast Cancer Adult: IV 30 mg/m2 weekly Hepatic Impairment Bilirubin 2.1–3 mg/dL: use 50% of dose; >3 mg/dL: use 25% of dose |
Administration
Intravenous
PREPARE: Direct: Dilute each 10 mg in a syringe with either 2 or 5 mL of D5W or NS to yield 3 mg/mL or 1.5 mg/L, respectively. IV Infusion: Dilute the required dose in an IV bag with D5W, NS, or RL to a final concentration of 0.5–2 mg/mL (example: 10 mg diluted in 19 mL yields 0.5 mg/mL). ADMINISTER: IV Infusion: Give diluted solution over 6–10 min into the side port closest to an IV bag with free-flowing IV solution; follow by flushing with at least 75–125 mL of IV solution over 10 min. Take every precaution to avoid extravasation. If suspected, discontinue IV immediately and begin in a different site.

Adverse Effects (≥1%)
CNS: Decreased deep tendon reflexes, paresthesia, fatigue, asthenia, peripheral neuropathy, myalgia, jaw pain. Hematologic: Anemia, neutropenia, granulocytopenia, thrombocytopenia. GI: Paralytic ileus, constipation, nausea, vomiting, diarrhea, stomatitis, mucositis, hepatotoxicity (elevated LFT). Body as a Whole: Pain on injection, venous pain, thrombophlebitis, alopecia, myalgia, muscle weakness.Interactions
Drug: Increased severity of granulocytopenia in combination with cisplatin; increased risk of acute pulmonary reactions in combination with mitomycin; paclitaxel may increase neuropathy.Pharmacokinetics
Distribution: 60–80% bound to plasma proteins (including platelets and lymphocytes); sequestered in tissues, especially lung, spleen, liver, and kidney, and released slowly. Metabolism: In liver (CYP3A4). Elimination: Primarily in bile and feces (50%), 10% in urine. Half-Life: 42–45 h.Nursing Implications
Assessment & Drug Effects
- Withhold drug and notify physician if the granulocyte count is <1000 cells/mm3.
- Montior for neurological dysfunction including parestheia, decreased deep tendon reflexes, weakness, constipation, and paralytic ileus.
- Lab tests: Monitor CBC with differential throughout therapy and on the day of treatment prior to each infusion. Monitor kidney and liver functions, and serum electrolytes periodically.
- Monitor for S&S of infection, especially during period of granulocyte nadir 7–10 d after dosing.
Patient & Family Education
- Be aware of potential and inevitable adverse effects.
- Women should use reliable forms of contraception to prevent pregnancy.
- Notify physician of distressing adverse effects, especially symptoms of leukopenia (e.g., chills, fever, cough) and peripheral neuropathy (e.g., pain, numbness, tingling in extremities).
- Report changes in bowel habits as soon as manifested.
