Granisetron Fresenius Kabi
Granisetron Fresenius Kabi Uses, Dosage, Side Effects, Food Interaction and all others data.
Granisetron Fresenius Kabi is a highly selective 5-HT3 receptor antagonist with little or no affinity for other serotonin receptors. It blocks serotonin peripherally on vagal nerve terminals and centrally in the chemoreceptor trigger zone.
Serotonin receptors of the 5-HT3 type are located peripherally on vagal nerve terminals and centrally in the chemoreceptor trigger zone of the area postrema. During chemotherapy that induces vomiting, mucosal enterochromaffin cells release serotonin, which stimulates 5-HT3 receptors. This evokes vagal afferent discharge, inducing vomiting. Animal studies demonstrate that, in binding to 5-HT3 receptors, granisetron blocks serotonin stimulation and subsequent vomiting after emetogenic stimuli such as cisplatin. In the ferret animal model, a single granisetron injection prevented vomiting due to high-dose cisplatin or arrested vomiting within 5 to 30 seconds.
In most human studies, granisetron has had little effect on blood pressure, heart rate or ECG. No evidence of an effect on plasma prolactin or aldosterone concentrations has been found in other studies.
Granisetron Fresenius Kabi is a selective inhibitor of type 3 serotonergic (5-HT3) receptors. Granisetron Fresenius Kabi has little or no affinity for other serotonin receptors, including 5-HT 1 , 5-HT 1A , 5-HT 1B/C , or 5-HT 2 ; for alpha 1 -, alpha 2 -, or beta-adrenoreceptors; for dopamine D 2 receptors; for histamine H 1 receptors; for benzodiazepine receptors; for picrotoxin receptors; or for opioid receptors. In most human studies, granisetron has had little effect on blood pressure, heart rate, or electrocardiogram (ECG). The drug is structurally and pharmacologically related to ondansetron, another selective inhibitor of 5-HT3 receptors. The serontonin 5-HT3 receptors are located on the nerve terminals of the vagus in the periphery, and centrally in the chemoreceptor trigger zone of the area postrema. The temporal relationship between the emetogenic action of emetogenic drugs and the release of serotonin, as well as the efficacy of antiemetic agents suggest that chemotherapeutic agents release serotonin from the enterochromaffin cells of the small intestine by causing degenerative changes in the GI tract. The serotonin then stimulates the vagal and splanchnic nerve receptors that project to the medullary vomiting center, as well as the 5-HT3 receptors in the area postrema, thus initiating the vomiting reflex, causing nausea and vomiting.

How Granisetron Fresenius Kabi works
Granisetron Fresenius Kabi 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.
Dosage
Granisetron Fresenius Kabi dosage
Tablet-
Emetogenic Chemotherapy: The recommended adult dosage of oral Granisetron Fresenius Kabiis 2 mg once daily or 1 mg twice daily. In the 2 mg once-daily regimen, two 1 mg tablets is given up to 1 hour before chemotherapy. In the 1 mg twice-daily regimen, the first 1 mg tablet is given up to 1 hour before chemotherapy, and the second tabletis given 12 hours after the first. Either regimen is administered only on the day(s) chemotherapy is given. Continued treatment, while not on chemotherapy, has not been found to be useful.
Injection-
Chemotherapy Induced Nausea and Vomiting:
- Adults: The recommended dosage for Granisetron Fresenius Kabi Injection is 10 mcg/kg administered intravenously within 30 minutes before initiation of chemotherapy, and only on the day(s) chemotherapy is given. Granisetron Fresenius Kabi Injection may be administered intravenously either undiluted over 30 seconds, or diluted with 0.9% Sodium Chloride or 5% Dextrose and infused over 5 minutes. As a general precaution, Granisetron Fresenius Kabi Injection should not be mixed in solution with other drugs.
- Paediatric Patients: The recommended dose in paediatric patients 2 to 16 years o f age is 10 mcg/kg. Paediatric patients under 2 years o f age have not beenstudied.
- Geriatric Patients, Renal Failure Patients or Hepatically Impaired Patients: No dosage adjustment is required.
Treatment of Postoperative Nausea and Vomiting:
- Adults: The recommended dosage for prevention of postoperative nausea and vomiting is, a single dose of 1 mg of Granisetron Fresenius Kabi should be diluted to 5 ml andadministered as a slow intravenous injection (over 30 seconds). Administration should be completed prior toinduction of anesthesia. The recommended dosage for the treatment of nausea and vomiting after surgery is 1 mg of Granisetron Fresenius Kabi undiluted, administered intravenously over 30 seconds.
- Paediatric Patients: Safety and effectiveness of Granisetron Fresenius Kabi Injection have not been established in paediatric patients for the prevention or treatment of post operative nausea or vomiting.
