Patient Counseling Information
This drug may cause fatigue and dizziness, if affected, do not drive or operate machinery.
MonitoringParameters
Verify baseline ANC, platelet and haemoglobin values before initiation of treatment. Monitor Na level during treatment, CBC and LFT.
Overdosage
Symptoms: Bone marrow suppression and risk of severe infection. Management: Closely monitor vital signs. May perform blood transfusion, administer antibiotics and growth factors as required.
Drug Interactions
May enhance the risk of constipation with opioids.
Potentially Fatal: Increased concentration with CYP3A4 inhibitors (e.g. ritonavir, ketoconazole). Decreased serum concentration with CYP3A4 inducers (e.g. rifampicin). Increased risk of ventricular arrhythmias with QTc prolonging agents.
Food Interaction
Increased concentration with grapefruit juice. Decreased serum concentration with St John’s wort.
Action
Description: Vinflunine is a fluorinated vinca alkaloid derived from vinorelbine. It binds to tubulin, thereby inhibiting its polymerisation and microtubule formation resulting in treadmilling suppression, disruption of microtubule dynamic, mitotic arrest and apoptosis in M phase (metaphase) of cell cycle.
Pharmacokinetics:
Distribution: Extensively distributed to tissues. Volume of distribution: Approx 35 L/kg. Plasma protein binding: 67.2 ± 1.1%.
Metabolism: Metabolised via formation of multiple esterases into active metabolite 4-O-deacetyl-vinflunine (DVFL) and into inactive metabolites via cytochrome CYP3A4 isoenzyme pathway.
Excretion: Mainly via faeces (approx 2/3); urine (approx 1/3). Terminal elimination half-life: Approx 40 hours (vinflunine); approx 120 hours (DVFL).
