Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

No price is published for this exact package yet. CMS surveys NADAC per package size, so a different pack of the same drug often has one.
Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

⚠️ Warnings and Cautions ~2 min read ▾

5 WARNINGS AND PRECAUTIONS Granisetron hydrochloride does not stimulate gastric or intestinal peristalsis and should not be used instead of nasogastric suction. (5.1) QT prolongation has been reported with granisetron hydrochloride. Use with caution in patients with pre-existing arrhythmias or cardiac conduction disorders.

(5.2) Hypersensitivity reactions, such as anaphylaxis, shortness of breath, hypotension, and urticaria, may occur in patients with known hypersensitivity to other selective 5-HT 3 receptor antagonists. (5.3) Serotonin syndrome has been reported with granisetron products, alone but particularly with concomitant use of serotonergic drugs. (5.4)

5.1Gastric or Intestinal Peristalsis Granisetron hydrochloride is not a drug that stimulates gastric or intestinal peristalsis. It should not be used instead of nasogastric suction. The use of granisetron hydrochloride in patients following abdominal surgery or in patients with chemotherapy-induced nausea and vomiting may mask a progressive ileus and/or gastric distention.

5.2Cardiovascular Events An adequate QT assessment has not been conducted, but QT prolongation has been reported with granisetron hydrochloride. Therefore, granisetron hydrochloride should be used with caution in patients with pre-existing arrhythmias or cardiac conduction disorders, as this might lead to clinical consequences. Patients with cardiac disease, on cardio-toxic chemotherapy, with concomitant electrolyte abnormalities and/or on concomitant medications that prolong the QT interval are particularly at risk.

5.3Hypersensitivity Reactions Hypersensitivity reactions (e.g., anaphylaxis, shortness of breath, hypotension, urticaria) may occur in patients who have exhibited hypersensitivity to other selective 5-HT 3 receptor antagonists.

5.4Serotonin Syndrome The development of serotonin syndrome has been reported with 5-HT 3 receptor antagonists. Most reports have been associated with concomitant use of serotonergic drugs (e.g., selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), monoamine oxidase inhibitors, mirtazapine, fentanyl, lithium, tramadol, and intravenous methylene blue). Some of the reported cases were fatal.

Serotonin syndrome occurring with overdose of another 5-HT 3 receptor antagonist alone has also been reported. The majority of reports of serotonin syndrome related to 5-HT 3 receptor antagonist use occurred in a post-anesthesia care unit or an infusion center. Symptoms associated with serotonin syndrome may include the following combination of signs and symptoms: mental status changes (e.g., agitation, hallucinations, delirium, and coma), autonomic instability (e.g., tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, with or without gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea).

Patients should be monitored for the emergence of serotonin syndrome, especially with concomitant use of granisetron and other serotonergic drugs. If symptoms of serotonin syndrome occur, discontinue granisetron and initiate supportive treatment. Patients should be informed of the increased risk of serotonin syndrome, especially if granisetron is used concomitantly with other serotonergic drugs [see Drug Interactions (7), Patient Counseling Information (17.1) ].

🤒 Adverse Reactions ~3 min read ▾

6 ADVERSE REACTIONS QT prolongation has been reported with granisetron hydrochloride [see Warnings and Precautions (5.2) and Drug Interactions (7) ] . Most common adverse reactions: Chemotherapy-induced nausea and vomiting (≥ 3%): Headache, and constipation (6.1) Postoperative nausea and vomiting (≥ 2%): Pain, headache, fever, abdominal pain and hepatic enzymes increased ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Eugia US LLC at 1-866-850-2876 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in patients. Chemotherapy-Induced Nausea and Vomiting The following have been reported during controlled clinical trials or in the routine management of patients. The percentage figures are based on clinical trial experience only.

Table 1 gives the comparative frequencies of the two most commonly reported adverse reactions (≥ 3%) in patients receiving granisetron hydrochloride injection, in single-day chemotherapy trials. These patients received chemotherapy, primarily cisplatin, and intravenous fluids during the 24-hour period following granisetron hydrochloride injection administration. Reactions were generally recorded over seven days post-granisetron hydrochloride injection administration.

Table 1 Principal Adverse Reactions in Clinical Trials — Single-Day Chemotherapy 1 Metoclopramide/dexamethasone and phenothiazines/dexamethasone. Percent of Patients With Reaction G ranisetron Hydrochlorid e Injection 40 mcg/kg (n = 1268) Comparator 1 (n = 422) Headache Constipation 14% 3% 6% 3% Additional adverse events reported in clinical trials were asthenia, somnolence and diarrhea. In over 3,000 patients receiving granisetron hydrochloride injection (2 to 160 mcg/kg) in single-day and multiple-day clinical trials with emetogenic cancer therapies, adverse events, other than those adverse reactions listed in Table 1, were observed; attribution of many of these events to granisetron hydrochloride is uncertain.

Hepatic: In comparative trials, mainly with cisplatin regimens, elevations of AST and ALT (> 2 times the upper limit of normal) following administration of granisetron hydrochloride injection occurred in 2.8% and 3.3% of patients, respectively. These frequencies were not significantly different from those seen with comparators (AST: 2.1%; ALT: 2.4%). Cardiovascular: Hypertension (2%); hypotension, arrhythmias such as sinus bradycardia, atrial fibrillation, varying degrees of A-V block, ventricular ectopy including non-sustained tachycardia, and ECG abnormalities have been observed rarely.

Central Nervous System: Agitation, anxiety, CNS stimulation and insomnia were seen in less than 2% of patients. Extrapyramidal syndrome occurred rarely and only in the presence of other drugs associated with this syndrome. Hypersensitivity: Rare cases of hypersensitivity reactions, sometimes severe (e.g., anaphylaxis, shortness of breath, hypotension, urticaria) have been reported.

Other: Fever (3%), taste disorder (2%), skin rashes (1%). In multiple-day comparative studies, fever occurred more frequently with granisetron hydrochloride injection (8.6%) than with comparative drugs (3.4%, P < 0.014), which usually included dexamethasone. Postoperative Nausea and Vomiting The adverse reactions listed in Table 2 were reported in ≥ 2% of adults receiving granisetron hydrochloride injection 1 mg during controlled clinical trials.

🔄 Drug Interactions ~2 min read ▾

7 DRUG INTERACTIONS Granisetron does not induce or inhibit the cytochrome P-450 drug-metabolizing enzyme system in vitro . There have been no definitive drug-drug interaction studies to examine pharmacokinetic or pharmacodynamic interaction with other drugs; however, in humans, granisetron hydrochloride injection has been safely administered with drugs representing benzodiazepines, neuroleptics and anti-ulcer medications commonly prescribed with antiemetic treatments. Granisetron hydrochloride injection also does not appear to interact with emetogenic cancer chemotherapies.

Because granisetron is metabolized by hepatic cytochrome P-450 drug-metabolizing enzymes, inducers or inhibitors of these enzymes may change the clearance and, hence, the half-life of granisetron. No specific interaction studies have been conducted in anesthetized patients. In addition, the activity of the cytochrome P-450 subfamily 3A4 (involved in the metabolism of some of the main narcotic analgesic agents) is not modified by granisetron hydrochloride in vitro .

In in vitro human microsomal studies, ketoconazole inhibited ring oxidation of granisetron hydrochloride. However, the clinical significance of in vivo pharmacokinetic interactions with ketoconazole is not known. In a human pharmacokinetic study, hepatic enzyme induction with phenobarbital resulted in a 25% increase in total plasma clearance of intravenous granisetron hydrochloride.

The clinical significance of this change is not known. QT prolongation has been reported with granisetron hydrochloride. Use of granisetron hydrochloride in patients concurrently treated with drugs known to prolong the QT interval and/or are arrhythmogenic may result in clinical consequences.

Serotonin syndrome (including altered mental status, autonomic instability, and neuromuscular symptoms) has been described following the concomitant use of 5-HT 3 receptor antagonists and other serotonergic drugs, including selective serotonin reuptake inhibitors (SSRIs) and serotonin and norepinephrine reuptake inhibitors (SNRIs) [see Warnings and Precautions (5.4) ] . Granisetron hydrochloride injection has been administered safely with benzodiazepines, neuroleptics, and anti-ulcer medications. (7) Does not appear to interact with emetogenic cancer chemotherapies.

(7) Inducers or inhibitors of CYP450 enzymes may change the clearance and therefore the half-life of granisetron. (7) Coadministration of granisetron hydrochloride with drugs known to prolong the QT interval and/or are arrhythmogenic may result in clinical consequences. (7)

👥 Use in Specific Populations ~3 min read ▾

8 USE IN SPECIFIC POPULATIONS Pregnancy: Use only if clearly needed. (8.1) Nursing mothers: Caution should be exercised when administered to a nursing woman. (8.3) Pediatric use: Safety and efficacy in pediatric patients have not been established for use in postoperative nausea and vomiting. (8.4) Geriatric use: No differences in responses between the elderly and younger patients were observed in reported clinical experience. (8.5)

8.1Pregnancy Teratogenic Effects Reproduction studies have been performed in pregnant rats at intravenous doses up to 9 mg/kg/day (54 mg/m 2 /day, 146 times the recommended human dose based on body surface area) and pregnant rabbits at intravenous doses up to 3 mg/kg/day (35.4 mg/m 2 /day, 96 times the recommended human dose based on body surface area) and have revealed no evidence of impaired fertility or harm to the fetus due to granisetron. There are, however, no adequate and well-controlled studies in pregnant women.

Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.

8.3Nursing Mothers It is not known whether granisetron is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when granisetron hydrochloride injection is administered to a nursing woman.

8.4Pediatric Use Chemotherapy-Induced Nausea and Vomiting [See Dosage and Administration (2) ] for use in chemotherapy-induced nausea and vomiting in pediatric patients 2 to 16 years of age. Safety and effectiveness in pediatric patients under 2 years of age have not been established. Postoperative Nausea and Vomiting Safety and efficacy have not been established in pediatric patients for the prevention of postoperative nausea and vomiting (PONV).

Granisetron has been evaluated in a pediatric patient clinical trial for use in the prevention of PONV. Due to the lack of efficacy and the QT prolongation observed in this trial, use of granisetron for the prevention of PONV in children is not recommended. The trial was a prospective, multicenter, randomized, double-blind, parallel-group trial that evaluated 157 children aged 2 to 16 years who were undergoing elective surgery for tonsillectomy or adenotonsillectomy.

The purpose of the trial was to assess two dose levels (20 mcg/kg and 40 mcg/kg) of intravenous granisetron in the prevention of PONV. There was no active comparator or placebo. The primary endpoint was total control of nausea and vomiting (defined as no nausea, vomiting/retching, or use of rescue medication) in the 24 hours following surgery.

Efficacy was not established due to lack of a dose response. The trial also included standard 12 lead ECGs performed pre-dose and after the induction of anesthesia. ECGs were repeated at the end of surgery after the administration of granisetron and just prior to reversal of anesthesia.

QT prolongation was seen at both dose levels. Five patients in this trial experienced an increase of ≥ 60 msec in QTcF. In addition, there were two patients whose QTcF was ≥ 500 msec.

Interpretation of the QTcF prolongation was confounded by multiple factors, including the use of concomitant medication and the lack of either a placebo or active control. A thorough QT trial in adults has not been performed. Other adverse events that occurred in the study included: vomiting (5 to 8%), post-procedural hemorrhage (3 to 5%), and dehydration (0 to 5%).

Pediatric patients under 2 years of age have not been studied.

8.5Geriatric Use During chemotherapy clinical trials, 713 patients 65 years of age or older received granisetron hydrochloride injection. The safety and effectiveness were similar in patients of various ages. During postoperative nausea and vomiting clinical trials, 168 patients 65 years of age or older, of which 47 were 75 years of age or older, received granisetron hydrochloride injection.

During postoperative nausea and vomiting clinical trials, 168 patients 65 years of age or older, of which 47 were 75 years of age or older, received granisetron hydrochloride injection.

Clinical studies of granisetron hydrochloride injection did not include sufficient numbers of subjects aged 65 years and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients.

🆘 Overdosage 44 words ▾

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Granisetron is a selective 5-hydroxytryptamine 3 (5-HT 3 ) receptor antagonist with little or no affinity for other serotonin receptors, including 5-HT 1 ; 5-HT 1A ; 5-HT 1B/C ; 5-HT 2 ; for alpha 1 -, alpha 2 - or beta-adrenoreceptors; for dopamine-D 2 ; or for histamine-H 1 ; benzodiazepine; picrotoxin or opioid receptors. Serotonin receptors of the 5-HT 3 type are located peripherally on vagal nerve terminals and centrally in the chemoreceptor trigger zone of the area postrema. During chemotherapy-induced vomiting, mucosal enterochromaffin cells release serotonin, which stimulates 5-HT 3 receptors.

This evokes vagal afferent discharge and may induce vomiting. Animal studies demonstrate that, in binding to 5-HT 3 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 hydrochloride injection exhibited no effect on oro-cecal transit time in normal volunteers given a single intravenous infusion of 50 mcg/kg or 200 mcg/kg.

Single and multiple oral doses slowed colonic transit in normal volunteers.

7.01Distribution Plasma protein binding is approximately 65% and granisetron distributes freely between plasma and red blood cells. Metabolism Granisetron metabolism involves N-demethylation and aromatic ring oxidation followed by conjugation. In vitro liver microsomal studies show that granisetron’s major route of metabolism is inhibited by ketoconazole, suggestive of metabolism mediated by the cytochrome P-450 3A subfamily.

Animal studies suggest that some of the metabolites may also have 5-HT 3 receptor antagonist activity. Elimination Clearance is predominantly by hepatic metabolism. In normal volunteers, approximately 12% of the administered dose is eliminated unchanged in the urine in 48 hours.

The remainder of the dose is excreted as metabolites, 49% in the urine, and 34% in the feces. Subpopulations Gender There was high inter- and intra-subject variability noted in these studies. No difference in mean AUC was found between males and females, although males had a higher C max generally.

Elderly The ranges of the pharmacokinetic parameters in elderly volunteers (mean age 71 years), given a single 40 mcg/kg intravenous dose of granisetron hydrochloride injection, were generally similar to those in younger healthy volunteers; mean values were lower for clearance and longer for half-life in the elderly patients (see Table 3).

Pediatric Patients A pharmacokinetic study in pediatric cancer patients (2 to 16 years of age), given a single 40 mcg/kg intravenous dose of granisetron hydrochloride injection, showed that volume of distribution and total clearance increased with age.

No relationship with age was observed for peak plasma concentration or terminal phase plasma half-life. When volume of distribution and total clearance are adjusted for body weight, the pharmacokinetics of granisetron are similar in pediatric and adult cancer patients. Renal Failure Patients Total clearance of granisetron was not affected in patients with severe renal failure who received a single 40 mcg/kg intravenous dose of granisetron hydrochloride injection.

Hepatically Impaired Patients A pharmacokinetic study in patients with hepatic impairment due to neoplastic liver involvement showed that total clearance was approximately halved compared to patients without hepatic impairment. Given the wide variability in pharmacokinetic parameters noted in patients, dosage adjustment in patients with hepatic functional impairment is not necessary. Postoperative Nausea and Vomiting In adult patients (age range, 18 to 64 years) recovering from elective surgery and receiving general balanced anesthesia, mean pharmacokinetic data obtained from a single 1 mg dose of granisetron hydrochloride injection administered intravenously over 30 seconds are shown in Table 4.

14 CLINICAL STUDIES

14.1Chemotherapy-Induced Nausea and Vomiting Single-Day Chemotherapy Cisplatin-Based Chemotherapy In a double-blind, placebo-controlled study in 28 cancer patients, granisetron hydrochloride injection, administered as a single intravenous infusion of 40 mcg/kg, was significantly more effective than placebo in preventing nausea and vomiting induced by cisplatin chemotherapy (see Table 5). Table 5 Prevention of Chemotherapy-Induced Nausea and Vomiting — Single-Day Cisplatin Therapy 1 1 Cisplatin administration began within 10 minutes of granisetron hydrochloride injection infusion and continued for 1.5 to 3 hours.

🧪 Nonclinical Toxicology ~2 min read ▾

13 NONCLINICAL TOXICOLOGY

13.1Carcinogenesis, Mutagenesis, Impairment of Fertility In a 24-month carcinogenicity study, rats were treated orally with granisetron 1, 5 or 50 mg/kg/day (6, 30 or 300 mg/m 2 /day). The 50 mg/kg/day dose was reduced to 25 mg/kg/day (150 mg/m 2 /day) during week 59 due to toxicity. For a 50 kg person of average height (1.46 m 2 body surface area), these doses represent 16, 81 and 405 times the recommended clinical dose (0.37 mg/m 2 , iv) on a body surface area basis.

There was a statistically significant increase in the incidence of hepatocellular carcinomas and adenomas in males treated with 5 mg/kg/day (30 mg/m 2 /day, 81 times the recommended human dose based on body surface area) and above, and in females treated with 25 mg/kg/day (150 mg/m 2 /day, 405 times the recommended human dose based on body surface area). No increase in liver tumors was observed at a dose of 1 mg/kg/day (6 mg/m 2 /day, 16 times the recommended human dose based on body surface area) in males and 5 mg/kg/day (30 mg/m 2 /day, 81 times the recommended human dose based on body surface area) in females.

In a 12-month oral toxicity study, treatment with granisetron 100 mg/kg/day (600 mg/m 2 /day, 1622 times the recommended human dose based on body surface area) produced hepatocellular adenomas in male and female rats while no such tumors were found in the control rats. A 24-month mouse carcinogenicity study of granisetron did not show a statistically significant increase in tumor incidence, but the study was not conclusive. Because of the tumor findings in rat studies, granisetron hydrochloride injection should be prescribed only at the dose and for the indication recommended [see Indications and Usage (1) and Dosage and Administration (2) ] .

Granisetron was not mutagenic in an in vitro Ames test and mouse lymphoma cell forward mutation assay, and in vivo mouse micronucleus test and in vitro and ex vivo rat hepatocyte UDS assays. It, however, produced a significant increase in UDS in HeLa cells in vitro and a significant increased incidence of cells with polyploidy in an in vitro human lymphocyte chromosomal aberration test. Granisetron at subcutaneous doses up to 6 mg/kg/day (36 mg/m 2 /day, 97 times the recommended human dose based on body surface area) was found to have no effect on fertility and reproductive performance of male and female rats.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The form printed on the packaging and shown on DailyMed is the one the FDA registered. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero and the dashes are dropped. The Identity section at the top of this page lists each form of this code.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Eugia US LLC. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
Eugia US LLC is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
