Ampoule containing solution of granisetron hydrochloride equivalent to 1mg granisetron per ml of isotonic solution.
Drugs List
Therapeutic Indications
Uses
For the management of nausea and vomiting induced by cytotoxic chemotherapy and radiotherapy.
Prevention and treatment of post-operative nausea and vomiting in adults
Not all presentations are licensed for all indications.
Dosage
Adults
Nausea and vomiting induced by cytostatic therapy:
Prevention:
1 to 3 mg (10 to 40 micrograms per kilogram bodyweight) of granisetron should be administered either as a slow intravenous injection (over 30 seconds) or as an intravenous infusion administered 5 minutes before the start of chemotherapy or radiotherapy. The solution should be diluted to 5 ml per mg.
Treatment:
The same dose of granisetron should be used for treatment as prevention. Additional doses should be administered at least 10 minutes apart.
Maximum daily dosage:
Up to three doses of 3 mg granisetron may be administered within a 24 hour period. The maximum dose of granisetron to be administered over 24 hours should not exceed 9 mg.
Post-operative nausea and vomiting:
Prevention:
A single dose of 1 mg (10 micrograms per kilogram bodyweight) of granisetron diluted to 5 ml and given as a slow intravenous injection (over 30 seconds) before induction of anaesthesia.
Treatment:
The same dose as used for prevention.
Maximum dose and duration:
3 mg (3 doses) within 24 hours.
Elderly
(See Dosage; Adult)
Children
Nausea and vomiting induced by cytostatic therapy:
Children aged 2 to 18 years
Intravenous infusion only.
Prevention:
A single dose of 10 to 40 micrograms per kilogram bodyweight (up to 3 mg) should be administered as an intravenous infusion, diluted in 10 to 30 ml infusion fluid and administered over 5 minutes before start of cytostatic therapy.
Treatment:
The same dose as used for prevention.
One additional dose of 40 micrograms per kilogram bodyweight (up to 3 mg) may be administered within a 24-hour period if required. This additional dose should be administered at least 10 minutes apart from the initial infusion.
Post-operative nausea and vomiting:
Not recommended.
Additional Dosage Information
The efficacy of parenteral granisetron may be enhanced by the addition of an intravenous adrenocortical steroid e.g 8 to 20 mg dexamethasone administered before the start of cytostatic therapy or by 250 mg methylprednisolone administered prior to the start and shortly after the end of chemotherapy.
Administration
To be administered after dilution by intravenous infusion or slow intravenous injection.
Reconstitution
For intravenous injection:
To prepare dose of 1mg, 1ml should be drawn from the ampoule and diluted to 5ml with 0.9% w/v sodium chloride injection. No other diluents should be used.
For intravenous infusion:
Intravenous infusions should be prepared at the time of administration. It must not be used after 24 hours. If it is to be stored after preparation, granisetron infusions must be prepared under appropriate aseptic conditions.
To prepare a dose of 3mg, 3ml is withdrawn from the ampoule and diluted either to 15ml with 0.9% sodium chloride injection (for bolus administration) or in infusion fluid to a total volume of 20 to 50ml in any of the solutions listed below.
To prepare the dose of 20-40 micrograms per kilogram, the appropriate volume is withdrawn and diluted with infusion fluid to a total volume of 10 to 30ml in any of the solutions listed below.
Any one of the following solutions may be used:
sodium chloride injection 0.9% w/v
Sodium chloride 0.18% w/v and glucose 4% w/v injection
glucose injection 5% w/v
sodium lactate compound injection
sodium lactate injection
mannitol injection 10%
No other diluents should be used.
Incompatibilities
Granisetron should not be mixed in solution with other drugs.
Prophylactic administration of granisetron should be completed prior to the start of cytostatic therapy or induction of anaesthesia.
Contraindications
Breastfeeding (see Lactation)
Precautions and Warnings
Patients with subacute intestinal obstruction should be monitored following administration as granisetron may reduce bowel motility.
Cases of ECG modifications including QT prolongation have been reported. The ECG changes were minor and generally not of clinical significance, specifically with no evidence of proarrhythmia.
Patients treated concurrently with drugs known to prolong QT interval, and/or with pre-existing arrhythmias or cardiac conduction disorders, may experience clinical consequences. Use with caution in patients with cardiac co-morbidities, receiving cardio-toxic chemotherapy and/or with concomitant electrolyte abnormalities.
Pregnancy- see Pregnancy section
Not all presentations are licensed for all indications
Do not mix with other drugs or substances unless compatibility known
For children under 18 years see- Dosage Children.
Contains sodium. This should be taken into consideration by patients on a controlled sodium diet.
Pregnancy and Lactation
Pregnancy
At the time of writing there are no reports of the use of granisetron during pregnancy although animal studies have shown no teratogenic effects. Use only where there are compelling clinical reasons.
The use of all medication in pregnancy should be avoided whenever possible; particularly in the first trimester. Non-drug treatments should also be considered. When essential, a medication with the best safety record over time should be chosen, employing the lowest effective dose for the shortest possible time. Polypharmacy should be avoided. Teratogens taken in the pre-embryonic period, often quoted as lasting until 14-17 days post-conception, are believed to have an all-or-nothing effect. Where drugs have a short half-life, and when the date of conception is certain, this may allow women to be reassured where drug exposure has occurred within this time frame. Further advice may be available from the UK National Teratology Information Service (NTIS) and through ToxBase, available via password on the internet ( www.toxbase.org ) or if this is unavailable at the backup site ( www.toxbasebackup.org ).
Lactation
At the time of writing there are no reports of the use of granisetron during breastfeeding but its molecular weight is low enough that transfer to milk would be expected. The manufacturer recommends that breast feeding is discontinued during therapy.
Neonates, infants born prematurely, those with low birth weight, those with an unstable gastrointestinal function or who have serious illnesses may require special consideration. For any infant, if a drug is prescribed to the nursing mother, it should be at the lowest practical dose and for the shortest time. When drug administration is unavoidable and breastfeeding is to continue, minimisation of exposure of the infant to the drug may sometimes be achieved by timing the maternal doses to just after a feeding episode. Infants exposed to drugs via breast milk should be monitored for unusual signs or symptoms. Interactions between the drug received by the infant from the mother's milk and medication prescribed for the infant should also be considered, for example, when the drug given to the infant may prevent metabolism of the drug received via breast milk.
