Naurif Tablet

Granisetron is a potent, selective antagonist of 5-HT3 receptors. The antiemetic activity of the drug is brought about through the inhibition of 5-HT3 receptors present both centrally (medullary chemoreceptor zone) and peripherally (GI tract). This inhibition of 5-HT3 receptors in turn inhibits the visceral afferent stimulation of the vomiting center, likely indirectly at the level of the area postrema, as well as through direct inhibition of serotonin activity within the area postrema and the chemoreceptor trigger zone.

Chemotherapy-induced nausea and vomiting:

• Adults: The recommended dosage for Granisetron Injection is 10mcg/kg administered intravenously within 30 minutes before initiation of chemotherapy and only on the day(s) chemotherapy is given.

Two 1 mg tablets are taken within one hour of irradiation.
• Pediatric use: There is no experience with oral Granisetron in the prevention of radiation-induced nausea and vomiting in pediatric patients.

Naurif does not induce or inhibit the cytochrome P-450 drug-metabolizing enzyme system. As Naurif is metabolized by hepatic cytochrome P-450 drug-metabolizing enzymes, inducers or inhibitors of these enzymes may change the clearance and the half-life of Naurif.

Granisetron is contraindicated in patients with known hypersensitivity to Granisetron or any of its components.

Headache, constipation, asthenia, diarrhea, abdominal pain, dyspepsia, nausea and vomiting, dizziness, insomnia, and anxiety.

Pregnancy category B. No evidence of impaired fertility or harm to the animal fetus has been found. However, this drug may be used in pregnancy only if clearly needed.
