Similar to other vinca alkaloids, vinblastine binds to the microtubular proteins of the mitotic spindle, leading to depolymerization of the microtubule and mitotic arrest at metaphase or cell death. It also has complex effects on nucleic acid and protein synthesis in high concentrations. Vinblastine has some immunosuppressant effects. The vinca alkaloids are considered to be cell cycle phase-specific (M and S phases).
Rapid and extensive binding to tissues and to formed elements of peripheral blood. Distributes to the liver.

Myelosuppression and neurotoxicity are the main dose-limiting effects of vinblastine.
Hyperuricemia during periods of active cell lysis, which is caused by cytotoxic chemotherapy of highly proliferative tumours of massive burden (e.g. some leukemias and lymphomas), can be minimized with allopurinol and hydration. In hospitalized patients the urine may be alkalinized, by addition of sodium bicarbonate to the IV fluids, if tumour lysis is expected.
Neurotoxicity with the vinca alkaloids is qualitatively similar but quantitatively different (vincristine> vinblastine>vinorelbine). Symptoms tend to be worse with prolonged exposure. Neurotoxicity may manifest as numbness, paresthesia, mental depression, loss of deep tendon reflex, headache, malaise, dizziness, seizures or psychosis. Cranial nerve neuropathy may lead to vocal cord paresis or paralysis, oculomotor nerve dysfunction, hearing impairment and facial nerve palsies. Vocal cord effects or facial nerve palsies tend to be bilateral and reversible when treatment with vinblastine is discontinued. High doses (> 20 mg) may be associated with autonomic neuropathy, which manifests as constipation, abdominal pain, urinary retention and paralytic ileus.
Severe jaw pain or parotid gland pain can occur within a few hours of the first dose of vinblastine. This is not an indication to stop or modify the dose; treat with analgesics.
Refer to protocol by which patient is being treated.
Dosage may be reduced and/or delayed in patients with bone marrow depression due to cytotoxic/radiation therapy. Do not re-treat with vinblastine until marrow recovery has occurred.
(range 3.7-18.5 mg/m2; usual weekly dose: 5.5 – 7.4 mg/m2; maximum weekly dose: 18.5 mg/m2)
Modify according to protocol by which patient is being treated.

FOR INTRAVENOUS USE ONLY.
Intrathecal administration of other vinca alkaloids has resulted in death. Containers with this product should be labelled:
“WARNING – FOR INTRAVENOUS USE ONLY. FATAL if given intrathecally.”
- Direct IV push is not recommended to reduce the risk of inadvertently administering vinca alkaloids via intrathecal route.
- Mix in 50 mL minibag (NS or D5W).
- Dilutions in large volumes (≥ 100mL) and infusions over ≥30-60 minutes are not recommended, since these can increase the risk of vein irritation and extravasation.
- If any signs or symptoms of extravasation occur, the injection or infusion should be immediately terminated and restarted in another vein. Any known or suspected extravasation should be managed promptly according to local guidelines.
- Store unopened vials at 2 to 8ºC; protect from light.
- Patients who have hypersensitivity to vinblastine or its formulation
- Patients with severe myelosuppression or infection
- Intrathecal vinblastine administration is absolutely contraindicated.
- Myelosuppressive effects are more marked in patients with bone marrow infiltration, cachexia or skin ulcers
- Use with caution in hepatic impairment due to an increased risk of neurotoxicity.
- Use with caution in patients with ischemic heart disease and in combination with neurotoxic drugs.
- Do not give vinblastine more frequently than once every 7 days.
- Standard doses of vinblastine given for prolonged periods (e.g. daily for 7 days) may result in permanent or fatal neurologic toxicity and should not be used.
Other Drug Properties:
Vinblastine is contraindicated in pregnancy. Adequate contraception should be used by both sexes during vinblastine treatment and for at least 6 months after the last dose (general recommendation).
Breast feeding is not recommended due to the potential secretion of vinblastine into breast milk.
Aspermia and amenorrhea have been reported. Recovery of menses is variable.
Vinblastine is metabolized by CYP3A4 and is a potent CYP3A4 inhibitor.
|Mitomycin||Acute bronchospasm has occurred minutes to hours after administration. Reaction may occur up to 2 weeks after mitomycin.||Unknown||Caution; discontinue vinblastine if this occurs|
|Phenytoin||↓ serum concentration of phenytoin||Possibly ↓ absorption or increased metabolism of phenytoin||Monitor serum levels of phenytoin and adjust dose as needed|
|CYP3A4 inhibitors (i.e. ketoconazole, voriconazole, clarithromycin, erythromycin, ritonavir, fruit or juice from grapefruit, Seville oranges, starfruit or pomegranate )||↑ risk of neurotoxicity||inhibition of vinblastine metabolism||Avoid concomitant use|
|CYP3A4 substrates (i.e., aprepitant, tolterodine)||↑ toxicity of CYP3A4 substrates||↓ metabolism of CYP3A4 substrates||Avoid if possible. If must use, monitor or adjust dose.|
|CYP3A4 inducers (i.e. phenytoin, rifampin, dexamethasone, carbamazepine, phenobarbital, St. John’s Wort, etc)||↓ vinblastine effect||↑ metabolism of vinblastine||Caution|
|Bleomycin +/- cisplatin||Raynaud's phenomenon, nephrotoxicity, neurotoxicity, MI, CVA reported||Unknown||Caution|
|Ototoxic drugs (i.e., cisplatin, aminoglycosides)||↑ ototoxicity (reported with other vinca alkaloids)||Additive||Caution|
Treating physicians may decide to monitor more or less frequently for individual patients but should always consider recommendations from the product monograph.
