What is Granisetron?
Granored is a prescription oral medication that contains the selective 5‑HT3 receptor antagonist granisetron. It is marketed in the European Union and is supplied without a specified strength or dosage form in the public data. Granisetron works by blocking serotonin receptors in the central nervous system, which helps to reduce the stimulation of the vomiting centre. Granored is used under medical supervision for nausea and vomiting control.
What is Granisetron used for?
Granored is indicated for the prevention and treatment of nausea and vomiting associated with specific medical procedures.
- Chemotherapy‑induced nausea and vomiting (CINV) - Post‑operative nausea and vomiting (PONV) - Nausea related to radiation therapy - Antiemetic prophylaxis in patients receiving highly emetogenic chemotherapy
What are the side effects of Granisetron?
The safety profile of granisetron includes both frequent, mild reactions and rare, more serious events.
Common: - Headache - Constipation - Diarrhoea - Fatigue - Dizziness
Serious: - Allergic reaction (rash, itching, swelling) - Cardiac arrhythmia - Severe hypotension
What precautions apply to Granisetron?
Before prescribing Granored, clinicians should evaluate patient history and consider several precautionary factors.
- Assess for known hypersensitivity to granisetron or other 5‑HT3 antagonists - Use cautiously in patients with prolonged QT interval or cardiac conduction disorders - Monitor electrolytes and cardiac status in patients receiving concurrent cardiotoxic chemotherapy - Adjust dose or avoid in severe hepatic impairment - Consider pregnancy and lactation status; safety data are limited
What does Granisetron interact with?
Granisetron may interact with other medicines, and certain combinations should be avoided or used with careful monitoring.
Avoid: - Concurrent use with other 5‑HT3 antagonists (e.g., ondansetron) due to additive effects - Co‑administration with drugs that significantly prolong the QT interval
Use with caution: - Antifungal agents such as ketoconazole that inhibit CYP3A4 - Certain anti‑emetics like aprepitant that affect metabolism - Drugs that alter cardiac conduction (e.g., certain antiarrhythmics)
