Adverse Reactions

6 ADVERSE REACTIONS The following adverse reactions have been identified from spontaneous reporting or clinical studies of barium sulfate administered orally. Because the reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or to establish a causal relationship to drug exposure Nausea, vomiting, diarrhea and abdominal cramping Serious adverse reactions and fatalities include aspiration pneumonitis, barium sulfate impaction, intestinal perforation with consequent peritonitis and granuloma formation, vasovagal and syncopal episodes Common adverse reactions include nausea, vomiting, diarrhea and abdominal cramping ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact Bracco Diagnostics Inc at 1-800-257-5181 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch

Dosage And Administration

2 DOSAGE AND ADMINISTRATION Adults: Recommended reconstituted oral dose is between 150 – 750 mL ( 2.1 ) Pediatric patients: adjust reconstituted dose based on relative GI volume ( 2.1 ) Must reconstitute supplied powder with water prior to use. See Full Prescribing Information for reconstitution instructions ( 2.2 ) 2.1 Recommended Dosage The optimal oral dose of E-Z-PAQUE will vary depending on the size and anatomy of the patient and the procedure being performed. The recommended oral dose of reconstituted E-Z-PAQUE: Adults: 150 to 750 mL, 169 to 450 g barium sulfate, depending on the reconstituted concentration [see Dosage and Administration ( 2.2 )] . Volumes closer to 150 mL are recommended for examination of the esophagus and stomach. Volumes up to 750 mL are recommended for examination of the small bowel. Pediatric Patients: Adjust dose of reconstituted E-Z-PAQUE based on GI volume. For examinations of the upper GI tract, administer a volume sufficient to fully distend the esophagus or stomach. For small bowel examinations: Age birth to less than 2 years: 30 mL to 75 mL. Age 2 years to less than 17 years: 75 mL to 480 mL. 2.2 Instructions for Reconstitution The reconstituted concentration will vary, depending on the procedure being performed. A barium suspension up to 115% w/v is recommended for examinations of the esophagus and upper GI A barium suspension of 60% w/v is recommended for examinations of the small bowel. Reconstitute the E-Z-PAQUE prior to administration according to the following instructions: Tap bottle on a hard surface (right side up) several times to compact the product in the bottle. Add water to the blue line marked ‘Initial Fill Line’ on the bottle. Replace cap securely on the bottle. Invert bottle and tap with fingers to mix contrast into the water. Shake vigorously for 30 seconds; wait 5 minutes. Add more water as needed to achieve the desired % w/v concentration using the fill lines marked on the bottle. Then, re-shake vigorously for 30 seconds. To use with straw, remove adhesive label on top of cap. Remove cap and use straw to push out cap liner; replace cap. 2.3 Administration Instructions Use immediately after reconstitution. Ensure patients have nothing by mouth for the following time period prior to the examination: Neonates and infants < 3 months 2 hours Infants 3-12 months 3 hours > 12 months of age 4 hours Discard any unused suspension. Encourage patients to maintain hydration following the barium sulfate procedure.

Indications And Usage

1 INDICATIONS AND USAGE E-Z-PAQUE is indicated for use in single contrast radiographic examinations of the esophagus, stomach, duodenum and small bowel to visualize the gastrointestinal tract (GI) in adult and pediatric patients. E-Z-PAQUE is a radiographic contrast agent indicated for use in single contrast radiographic examinations of the esophagus, stomach, duodenum and small bowel to visualize the gastrointestinal (GI) tract in adult and pediatric patients ( 1 )

Clinical Pharmacology

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Due to its high atomic number, barium (the active ingredient in E-Z-PAQUE) is opaque to x-rays and therefore acts as a positive contrast agent for radiographic studies. 12.3 Pharmacokinetics Under physiological conditions, barium sulfate passes through the GI tract in an unchanged form and is absorbed only in pharmacologically insignificant amounts.

Use In Specific Populations

8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Risk Summary E-Z-PAQUE is not absorbed systemically following oral administration, and maternal use is not expected to result in fetal exposure to the drug [see Clinical Pharmacology ( 12.3 )] . 8.2 Lactation Risk Summary E-Z-PAQUE is not absorbed systemically by the mother following oral administration, and breastfeeding is not expected to result in exposure of the infant to E-Z-PAQUE [see Clinical Pharmacology ( 12.3 )] . 8.4 Pediatric Use The efficacy of E-Z-PAQUE in pediatric patients from birth to less than 17 years of age is based on successful opacification of the esophagus, stomach, duodenum and small bowel during radiologic examinations [see Clinical Pharmacology ( 12.1 )] . Safety and dosing recommendations in pediatric patients are based on clinical experience [see Dosage and Administration ( 2.1 )] . E-Z-PAQUE is contraindicated in pediatric patients with tracheo-esophageal fistula [see Contraindications ( 4 )]. Pediatric patients with a history of asthma or food allergies may be at increased risk for development of hypersensitivity reactions [see Warnings and Precautions ( 5.1 )]. Pediatric patients with cystic fibrosis or Hirschsprung disease should be monitored for bowel obstruction after use [see Warnings and Precautions ( 5.3 )]. Pediatric patients with hereditary fructose intolerance may develop severe symptoms with administration of E-Z-Paque; assess for this risk and avoid use in patients with hereditary fructose intolerance [see Warnings and Precautions ( 5.6 )] . 8.5 Geriatric Use Clinical studies of E-Z-PAQUE did not include sufficient numbers of subjects aged 65 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. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
