Contraindications
Hypersensitivity to vinorelbine or other vinca alkaloids; severe current or recent infection (within last 2 wk); neutropenia; thrombocytopenia; severe hepatic impairment. Intrathecal admin. Do not give concomitantly with radiotherapy if liver is in treatment field. Pregnancy, lactation.
Side Effects & Adverse Reactions
Most common adverse reactions (incidence ≥20%) are leukopenia, neutropenia, anemia, increased aspartate aminotransferase, nausea, vomiting, constipation, asthenia, injection site reaction and peripheral neuropathy.
Warnings & Precautions
Hepatic Toxicity: Monitor hepatic function prior to initiation and during treatment.
Severe constipation and bowel obstruction, including necrosis and perforation, occur. Institute a prophylactic bowel regimen to mitigate potential constipation, bowel obstruction and/or paralytic ileus.
Extravasation can result in severe tissue injury, local tissue necrosis and/or thrombophlebitis. Immediately stop Vinorel and institute recommended management procedures.
Neurologic Toxicity: Severe sensory and motor neuropathies occur. Monitor patients for new or worsening signs and symptoms of neuropathy. Discontinue for Grade 2 or greater neuropathy
Pulmonary toxicity and respiratory failure occur. Interrupt Vinorel in patients who develop unexplained dyspnea or have any evidence of pulmonary toxicity. Permanently discontinue for confirmed interstitial pneumonitis or ARDA.
Embryo-Fetal Toxicity: Can cause fetal harm. Advise females of reproductive potential of potential risk to the fetus and to use effective contraception.
Pharmacology & Mechanism of Action
Vinorelbine is a vinca alkaloid that interferes with microtubule assembly. The antitumor activity of vinorelbine is thought to be due primarily to inhibition of mitosis at metaphase through its interaction with tubulin. Vinorelbine may also interfere with: 1) amino acid, cyclic AMP and glutathione metabolism, 2) calmodulin-dependent Ca

transport ATPase activity, 3) cellular respiration, and 4) nucleic acid and lipid biosynthesis. Vinorelbine inhibited mitotic microtubule formation in intact mouse embryo tectal plates at a concentration of 2 µM inducing a blockade of cells at metaphase, but produced depolymerization of axonal microtubules at a concentration 40 µM, suggesting a modest selectivity of vinorelbine for mitotic microtubules.
