4 CONTRAINDICATIONS

Famotidine Injection is contraindicated in patients with a history of serious hypersensitivity reactions (e.g., anaphylaxis) to famotidine or other H2-receptor antagonists.

5 WARNINGS AND PRECAUTIONS

5.1 Central Nervous System Adverse Reactions

Central nervous system (CNS) adverse reactions, including confusion, delirium, hallucinations, disorientation, agitation, seizures, and lethargy, have been reported in elderly patients and patients with moderate and severe renal impairment treated with famotidine. Monitor elderly patients for CNS adverse reactions [see Use in Specific Populations (8.5)]. Dosage adjustments are recommended in adult patients with moderate and severe renal impairment due to higher famotidine systemic exposure compared to patients with normal renal function [see Dosage and Administration (2.3), Use in Specific Populations (8.6), and Clinical Pharmacology (12.3)].

5.2 Concurrent Gastric Malignancy

In adults, symptomatic response to therapy with Famotidine Injection does not preclude the presence of gastric malignancy. Consider evaluation for gastric malignancy in adult patients who have a suboptimal response or an early symptomatic relapse after completing treatment with Famotidine Injection.

5.3 Risk of Benzyl Alcohol Toxicity in Neonates

Famotidine Injection is not approved in neonates. Serious adverse reactions, including fatal reactions, of new onset or worsening metabolic acidosis that progressed to neurotoxicity, and in some cases gasping syndrome, have been reported in low-birth weight neonates (less than 2,500 grams) and preterm neonates (gestational age less than 34 weeks) who received benzyl alcohol (BA)-containing drugs intravenously. Gasping syndrome is a life-threatening condition in neonates caused by BA toxicity and is primarily characterized by multiorgan dysfunction secondary to metabolic acidosis, which leads to gasping respirations and death. The minimum amount of BA at which these serious adverse reactions, including fatal reactions, may occur is not known (Famotidine Injection contains 3.6 mg of BA per mL) [see Use in Specific Populations (8.4)].

6 ADVERSE REACTIONS

6.1 Clinical 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 practice.

The safety of Famotidine Injection has been established based on adequate and well-controlled studies of an oral famotidine product. The following is a summary of the adverse reactions reported in those studies.

Oral famotidine was studied in 7 U.S. and international placebo- and active-controlled trials in approximately 2,500 patients. A total of 1,442 patients were treated with oral famotidine, including 302 treated with 40 mg twice daily, 456 treated with 20 mg twice daily, 461 treated with 40 mg once daily, and 396 treated with 20 mg once daily. The population was 17 to 91 years old, fairly well distributed between sex and race; however, the predominant race was White.

Adverse reactions reported in ≥1% of patients treated with oral famotidine in clinical trials were: headache, dizziness, constipation, and diarrhea.

The following other adverse reactions were reported in less than 1% of patients treated with oral famotidine in clinical trials:

Body as a Whole: fever, asthenia, fatigue

Cardiovascular: palpitations

Gastrointestinal: cholestatic jaundice, elevated liver enzymes, vomiting, nausea, abdominal discomfort, anorexia, dry mouth

Hematologic: thrombocytopenia

Hypersensitivity: orbital edema, rash, conjunctival injection, bronchospasm

Musculoskeletal: musculoskeletal pain, arthralgia

Nervous System/Psychiatric: seizure, hallucinations, depression, anxiety, decreased libido, insomnia, somnolence

Respiratory: interstitial pneumonia

Skin: pruritus, dry skin, flushing

Special Senses: tinnitus, taste disorder

Other: impotence

Adverse reactions reported with oral famotidine may also occur with Famotidine Injection. In addition, transient irritation at the injection site was reported with intravenous famotidine.

6.2 Postmarketing Experience

The following adverse reactions have been identified during post-approval use of famotidine. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Cardiovascular: arrhythmia, AV block, prolonged QT interval

Gastrointestinal: cholestatic jaundice, hepatitis

Hematologic: agranulocytosis, pancytopenia, leukopenia

Hypersensitivity: anaphylaxis, angioedema, facial edema, urticaria

Musculoskeletal: rhabdomyolysis, muscle cramps

Nervous System/Psychiatric: confusion, agitation, paresthesia

Respiratory: interstitial pneumonia

Skin: toxic epidermal necrolysis/Stevens-Johnson syndrome

7 DRUG INTERACTIONS

7.1 Drugs Dependent on Gastric pH for Absorption

Famotidine can reduce the absorption of other drugs due to its effect on reducing intragastric acidity, leading to loss of efficacy of the concomitant drug. See the prescribing information for other drugs dependent on gastric pH for absorption.

7.2 Tizanidine (CYP1A2 Substrate)

Although not studied clinically, famotidine is considered a weak CYP1A2 inhibitor and may lead to substantial increases in blood concentrations of tizanidine, a CYP1A2 substrate. Avoid concomitant use with Famotidine Injection. If concomitant use is necessary, monitor for hypotension, bradycardia or excessive drowsiness. Refer to the full prescribing information for tizanidine.

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Risk Summary

Available data with H2-receptor antagonists, including famotidine, in pregnant women over decades of use have not identified a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. Reproductive studies have been performed in rats and rabbits at intravenous doses of up to 200 mg/kg/day, with no obvious adverse developmental effects (see Data). Famotidine Injection contains benzyl alcohol as a preservative [see How Supplied/Storage and Handling (16)]. Because benzyl alcohol is rapidly metabolized by a pregnant female, benzyl alcohol exposure in the fetus is unlikely.

The background risk for major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Data

Animal Data

Reproductive studies have been performed in rats and rabbits at oral doses of up to 2,000 and 500 mg/kg/day, respectively, and in both species at intravenous doses of up to 200 mg/kg/day and have revealed no significant evidence of impaired fertility or harm to the fetus due to famotidine.

8.2 Lactation

Risk Summary

There are limited data available on the presence of famotidine in human breast milk following oral administration. There were no effects on the breastfed infant. There are no data on famotidine effects on milk production. Famotidine Injection contains benzyl alcohol as a preservative. Because benzyl alcohol is rapidly metabolized by a lactating female, benzyl alcohol exposure in the breastfed neonate is unlikely.

The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Famotidine Injection and any potential adverse effects on the breastfed child from famotidine or from the underlying maternal condition.

8.4 Pediatric Use

Peptic Ulcer Disease

The safety and effectiveness of Famotidine Injection have been established in pediatric patients 1 year to less than 17 years of age for the treatment of peptic ulcer disease in hospitalized patients or as an alternative to oral famotidine. Use of Famotidine Injection in this age group is supported by evidence from adequate and well-controlled studies of oral famotidine in adults with additional pharmacokinetic and pharmacodynamic data in pediatric patients 1 year to less than 17 years of age [see Dosage and Administration (2.2) and Clinical Pharmacology (12.2, 12.3)].

A safe and effective dosage has not been established in pediatric patients 1 year to less than 17 years of age with renal impairment for the treatment of peptic ulcer disease.

The safety and effectiveness of Famotidine Injection for the treatment of peptic ulcer disease in pediatric patients less than 1 year of age have not been established.

Other Conditions

The safety and effectiveness of Famotidine Injection for the treatment of symptomatic nonerosive GERD, erosive esophagitis due to GERD, pathological hypersecretory conditions and reduction of the risk of DU recurrence have not been established in pediatric patients.

Risk of Benzyl Alcohol Toxicity in Neonates

Famotidine Injection is not approved for use in neonates. Serious adverse reactions, including fatal reactions, of new onset or worsening metabolic acidosis that progressed to neurotoxicity, and in some cases gasping syndrome, have been reported in low-birth weight neonates and preterm neonates who received benzyl alcohol (BA)-containing drugs intravenously. Gasping syndrome is a life-threatening condition in neonates caused by BA toxicity that is characterized by new onset or worsening metabolic acidosis with gradual neurological deterioration, seizures, intracranial hemorrhage, hematologic abnormalities, skin breakdown, hepatic and kidney failure, hypotension, bradycardia, and gasping respirations followed by death. In reported cases, BA in amounts of 99 to 234 mg/kg/day produced blood BA levels of 6.6 to 14.9 mg/dL, but the minimum amount of BA at which gasping syndrome may occur in neonates is not known (Famotidine Injection contains 3.6 mg of BA per mL) [see Warnings and Precautions (5.3)].

8.5 Geriatric Use

Of the 1,442 patients treated with oral famotidine in clinical studies, approximately 10% were 65 and older. In these studies, no overall differences in safety or effectiveness were observed between elderly and younger patients. In elderly patients, there are no clinically significant age-related changes in the pharmacokinetics of famotidine [see Clinical Pharmacology (12.3)].

In postmarketing experience, CNS adverse reactions have been reported in elderly patients with and without renal impairment receiving famotidine. Monitor elderly patients for CNS adverse reactions [see Warnings and Precautions (5.1)]. Famotidine is known to be substantially excreted by the kidney, and the risk of adverse reactions to Famotidine Injection may be greater in elderly patients, particularly those with impaired renal function [see Dosage and Administration (2.3) and Use in Specific Populations (8.6)].

8.6 Renal Impairment

CNS adverse reactions and prolonged QT intervals have been reported in patients with moderate and severe renal impairment [see Warnings and Precautions (5.1)]. The clearance of famotidine is reduced in adults with moderate and severe renal impairment compared to adults with normal renal function [see Clinical Pharmacology (12.3)]. The recommended dosage in adults with moderate or severe renal impairment (creatinine clearance <60 mL/minutes) is less than the recommended dosage in adults with normal renal function [see Dosage and Administration (2.3)]. The recommended dosage in adults with mild renal impairment (creatinine clearance ≥60 mL/minute) is the same as the recommended dosage in adults with normal renal function.

Data are not available to establish a safe and effective dosage in pediatric patients 1 year to less than 17 years of age with renal impairment for the treatment of peptic ulcer disease.

10 OVERDOSAGE

Adverse reactions reported in cases of overdosage are similar to the adverse reactions reported with use of the recommended dosage [see Adverse Reactions (6)]. In the event of overdosage, treatment should be symptomatic and supportive. In the event of overdosage, monitor the patient, and employ supportive therapy. Due to low binding to plasma proteins, famotidine is eliminated by hemodialysis. There is limited experience on the usefulness of hemodialysis as a treatment for famotidine overdosage.

Consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdose management recommendations.

11 DESCRIPTION

The active ingredient in Famotidine Injection is a histamine H2-receptor antagonist.

Famotidine, USP is N'-(aminosulfonyl)-3-[[[2-[ ( diaminomethylene )amino ]-4 thiazolyl]methyl]thio]propanimidamide. The empirical formula of famotidine is C8H15N7O2S3 and its molecular weight is 337.45. Its structural formula is:

Famotidine, USP is a white to pale yellow crystalline compound that is freely soluble in glacial acetic acid, slightly soluble in methanol, very slightly soluble in water, and practically insoluble in ethanol.

Famotidine Injection is supplied as a premixed, ready-to-use, sterile solution for intravenous injection. Each mL contains 4 mg of famotidine and the following inactive ingredients: L-aspartic acid 1.6 mg, mannitol 8 mg, sodium chloride 7 mg, and Water for Injection q.s. 1 mL. The multiple-dose vials of 10 mL and 50 mL also contain benzyl alcohol 0.36% (3.6 mg per mL) added as a preservative. The pH ranges for all three concentrations range from 5.7 to 6.4 and may have been adjusted with sodium hydroxide.

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Famotidine is a competitive inhibitor of histamine H2-receptors. The primary clinically important pharmacologic activity of famotidine is inhibition of gastric secretion. Both the acid concentration and volume of gastric secretion are suppressed by famotidine, while changes in pepsin secretion are proportional to volume output.

12.2 Pharmacodynamics

Adults

Famotidine inhibited basal and nocturnal gastric secretion, as well as secretion stimulated by food and pentagastrin. After intravenous administration, the maximum effect was achieved within 30 minutes. Single intravenous doses of 20 mg inhibited nocturnal secretion for a period of 10 to 12 hours.

Famotidine had little or no effect on fasting or postprandial serum gastrin levels. Gastric emptying and exocrine pancreatic function were not affected by famotidine.

In clinical pharmacology studies, systemic effects of famotidine in the central nervous system (CNS), cardiovascular, respiratory or endocrine systems were not noted. Also, no antiandrogenic effects were noted. Serum hormone levels, including prolactin, cortisol, thyroxine (T4), and testosterone, were not altered after treatment with famotidine.

Pediatric Patients

Pharmacodynamics of famotidine were evaluated in five pediatric patients 2 to 13 years of age using the sigmoid Emax model. These data suggest that the relationship between serum concentration of famotidine and gastric acid suppression is similar to that observed in one study of adults (Table 4).

0.5 mg/kg twice daily 4 gastric pH >5 for 13.5 ± 1.8b hours 6 to 15 years

12.3 Pharmacokinetics

Plasma levels after multiple doses are similar to those after single doses.

Distribution

Fifteen to 20% of famotidine in plasma is protein bound.

Elimination

Metabolism

Famotidine undergoes minimal first-pass metabolism. Sixty-five to 70% of an intravenous dose are recovered in the urine as unchanged compound. The only metabolite identified in humans is the S-oxide.

Excretion

Famotidine has an elimination half-life of 2.5 to 3.5 hours. Famotidine is eliminated by renal (65 to 70%) and metabolic (30 to 35%) routes. Renal clearance is 250 to 450 mL/minutes, indicating some tubular excretion.

Specific Populations

Pediatric Patients

Table 6 presents pharmacokinetic data for famotidine administered intravenously. Areas under the curve (AUCs) are normalized to a 0.5 mg/kg intravenous dose for pediatric patients 1 to 15 years of age and compared with an extrapolated 40 mg intravenous dose in adults. Extrapolation is based on results obtained with a 20 mg intravenous adult dose). The pharmacokinetic parameters for pediatric patients, aged 1 year to 15 years, are comparable to those obtained for adults.

Geriatric Patients

In elderly patients, there are no clinically significant age-related changes in the pharmacokinetics of famotidine. However, in elderly patients with decreased renal function, the clearance of the drug may be decreased [see Use in Specific Populations (8.5)].

Patients with Renal Impairment

In adult patients with severe renal impairment (creatinine clearance less than 30 mL/min), the systemic exposure (AUC) of famotidine increased at least 5-fold. In adult patients with moderate renal impairment (creatinine clearance between 30 to 60 mL/minute), the AUC of famotidine increased at least 2-fold [see Dosage and Administration (2.3) and Use in Specific Populations (8.6)].

Drug Interaction Studies

Human Organic Anion Transporter (OAT) 1 and 3

In vitro studies indicate that famotidine is a substrate for OAT1 and OAT3. Following coadministration of probenecid (1500 mg), an inhibitor of OAT1 and OAT3, with a single oral 20 mg dose of famotidine in eight healthy subjects, the serum AUC0-10h of famotidine increased from 424 to 768 ng•hr/mL and the maximum serum concentration (Cmax) increased from 73 to 113 ng/mL. Renal clearance, urinary excretion rate and amount of famotidine excreted unchanged in urine were decreased. The clinical relevance of this interaction is unknown.

Multidrug and Toxin Extrusion Protein 1 (MATE-1)

An in vitro study showed that famotidine is an inhibitor of MATE-1. However, no clinically significant interaction with metformin, a substrate for MATE-1, was observed.

CYP1A2

Famotidine is a weak CYP1A2 inhibitor [see Drug Interaction (7.2)]

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

The carcinogenic potential of intravenously administered famotidine has not been determined. In a 106-week study in rats and a 92-week study in mice given oral doses of up to 2,000 mg/kg/day there was no evidence of carcinogenic potential for famotidine.

Famotidine was negative in the bacterial mutagen test (Ames test) using Salmonella typhimurium and Escherichia coli with or without rat liver enzyme activation at concentrations up to 10,000 mcg/plate. In in vivo studies in mice, with a micronucleus test and a chromosomal aberration test, no evidence of a mutagenic effect was observed.

In studies with rats given oral doses of up to 2,000 mg/kg/day or intravenous doses of up to 200 mg/kg/day, fertility and reproductive performance were not affected.
