Kytril -->

Good day,
Good night,
Good morning

1 mg or 2 mg tablets and 1 mg/1 ml or 3 mg/3 ml solutions for injection

For acute nausea and vomiting in adults associated with:
CINV = Chemotherapy Induced Nausea & Vomiting1-4
RINV = Radiotherapy Induced Nausea & Vomiting1-4
PONV = Post-Operative Nausea & Vomiting3,4

A long half-life is the key to Kytril’s lasting action1–5

  • Ondansetron IV: half-life 4 hours – duration of effect of 12–24 hours5
  • Kytril IV: half-life 9 hours3-5 – duration of effect of more than 24 hours5
IV = Intravenous

When they need it most in CINV6

In patients receiving highly emetogenic chemotherapy including cisplatin6

Kytril 3 mg/ml IV or ondansetron 8 mg IV, plus dexamethasone 8 mg IV immediately prior to therapy.
Oral dexamethasone 4 mg three times a day on days 2 to 4 of therapy (n=21). Double-blind crossover study.6
Kytril “ significantly better on day 2 when the majority of patients suffer most.“ 6
  • Palonosetron 0.25 mg IV and Kytril 1 mg/ml IV have similar effects on delayed nausea7
IV = Intravenous    CINV = Chemotherapy Induced Nausea & Vomiting

Kytril oral tablets offer reliable, lasting control in RINV8

Patients receiving hyperfractionated total body irradiation (TBI)
over a 4-day period8

p <0.01 vs. historic control for both treatment groups8
  • The proportion of patients with >5 emetic episodes over the 4 days was significantly less in the Kytril group (0%; p<0.01) but not in the ondansetron group (20%), vs. the control group (55.6%)8
Kytril 2 mg/ml (administered as two 1 mg tablets, n=18) was given once daily, 1 h prior to the administration of the first daily fraction of radiation. Ondansetron 8 mg (n=15) was given 1.5 h prior to every fraction of radiation (three times daily for days 0 to 3 and twice daily on day 4). Control did not receive a 5-HT3-receptor antagonist, (n=90)8. All patients had a diagnosis of either malignant disease or aplastic anaemia, and were hospitalised to receive 11 fractions each of 120 cGy of radiation over the course of 4 days for a total radiation exposure of 1320 cGy prior to bone marrow transplantation and the initiation of any conditioning chemotherapy.8
IV = Intravenous    RNIV = Radiotherapy Induced Nausea & Vomiting

Kytril IV controls PONV throughout the whole day9

Patients undergoing surgical procedures with spinal anaesthesia9

  • Kytril was significantly more effective in the late postoperative period (3-24 hours)9
  • A complete response (absence of nausea and vomiting) was seen in significantly more Kytril patients (86.7%, p<0.05) than ondansetron patients (60%)9
Patients undergoing gynaecological surgical procedures under spinal anaesthesia were randomised to two groups (each n=30): Kytril 2 mg/ml IV or ondansetron 4 mg IV 5 minutes before induction of anaesthesia9
IV = Intravenous    PONV = Post-Operative Nausea & Vomiting

Kytril has good tolerability1–4

  • The most commonly reported adverse reactions for Kytril (≥ 1/10) are headache and constipation, which may be transient
  • ECG changes including QT prolongation have been reported with Kytril and with other 5-HT3 antagonists
  • Other adverse events –
    Common (1/100 to <1/10): insomnia, diarrhoea, elevated hepatic transaminases (occurred at similar frequency to comparator therapy)
    Uncommon (1/1,000 to <1/100): hypersensitivity reactions, e.g. anaphylaxis, urticaria, extrapyrimidal reactions, serotonin syndrome, rash
