CLINICAL PHARMACOLOGY SECTION.


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

USE IN SPECIFIC POPULATIONS SECTION.


8 USE IN SPECIFIC POPULATIONS. 8.1 Pregnancy. Risk SummaryE-Z-HD is not absorbed systemically followingoral administration, and maternal use is not expected to result infetal exposure to the drug.. 8.2 Lactation. Risk SummaryE-Z-HDis not absorbed systemically by the mother following oral administration,and breastfeeding is not expected to result in exposure of the infantto E-Z-HD.. 8.4 Pediatric Use. Double-contrast radiographicexaminations of the esophagus, stomach and duodenum may be used inpediatric patients 12 years and older.E-Z-HD is contraindicatedin pediatric patients with tracheo-esophageal fistula. [seeContraindications (4)]. Pediatricpatients with history of asthma or food allergies may be at increasedrisk for development of hypersensitivity reactions [see Warningsand Precautions (5.1)]. Pediatric patients with cystic fibrosis or Hirschsprung disease shouldbe monitored for bowel obstruction after use [see Warningsand Precautions (5.3)] 8.5 GeriatricUse. Clinicalstudies of E-Z-HD did not include sufficient numbers of subjects aged65 and over to determine whether they respond differently from youngersubjects. Other reported clinical experience has not identified differencesin responses between the elderly and younger patients. In general,dose selection for an elderly patient should be cautious, usuallystarting at the low end of the dosing range, reflecting the greaterfrequency of decreased hepatic, renal, or cardiac function, and ofconcomitant disease or other drug therapy.

WARNINGS AND PRECAUTIONS SECTION.


5 WARNINGS AND PRECAUTIONS. Emergency equipment and trained personnel should be immediatelyavailable for treatment of serious hypersensitivity reaction (5.1)Intra-abdominal leakage: Caution is recommended in patientconditions like GI fistula, ulcer, inflammatory bowel disease, appendicitisor diverticulitis, severe stenosis or obstructing lesions of the GItract (5.2) Patients should maintain adequate hydration in days followinga barium sulfate procedure to avoid obstruction or impaction causedby baroliths (5.3)Aspiration: Caution is recommended in patients with historyof food aspiration and in patients with known swallowing disorders(5.4)E-Z-HD is not intended for pediatric use from birth through11 years of age (8.4). Emergency equipment and trained personnel should be immediatelyavailable for treatment of serious hypersensitivity reaction (5.1). Intra-abdominal leakage: Caution is recommended in patientconditions like GI fistula, ulcer, inflammatory bowel disease, appendicitisor diverticulitis, severe stenosis or obstructing lesions of the GItract (5.2) Patients should maintain adequate hydration in days followinga barium sulfate procedure to avoid obstruction or impaction causedby baroliths (5.3). Aspiration: Caution is recommended in patients with historyof food aspiration and in patients with known swallowing disorders(5.4). E-Z-HD is not intended for pediatric use from birth through11 years of age (8.4). 5.1 HypersensitivityReactions. Barium sulfate preparations contain number of excipients, includingnatural and artificial flavors and may induce serious hypersensitivityreactions. The manifestations include hypotension, bronchospasm andother respiratory impairments, dermal reactions including rashes,urticaria, and itching. history of bronchial asthma, atopy, ora previous reaction to contrast agent may increase the risk forhypersensitivity reactions. Emergency equipment and trained personnelshould be immediately available for treatment of hypersensitivityreaction.. 5.2 Intra-abdominal BariumLeakage. Theuse of E-Z-HD is contraindicated in patients at high risk of perforationof the GI tract [see Contraindications (4)]. Administration of E-Z-HD may result in leakageof barium from the GI tract in the presence of conditions such ascarcinomas, GI fistula, inflammatory bowel disease, gastric or duodenalulcer, appendicitis, or diverticulitis, and in patients with severestenosis at any level of the GI tract, especially if it is distalto the stomach. The barium leakage has been associated with peritonitisand granuloma formation. 5.3 Delayed GastrointestinalTransit and Obstruction. Orally administered bariumsulfate may accumulate proximal to constricting lesion of the colon,causing obstruction or impaction with development of baroliths (inspissatedbarium associated with feces) and may lead to abdominal pain, appendicitis,bowel obstruction, or rarely perforation. Patients with the followingconditions are at higher risk for developing obstruction or baroliths: severe stenosis at any level of the GI tract, impaired GI motility,electrolyte imbalance, dehydration, on low residue diet, takingmedications that delay GI motility, constipation, pediatric patientswith cystic fibrosis or Hirschsprung disease, and the elderly [see Use in Specific Populations (8.4, 8.5)]. To reduce therisk of delayed GI transit and obstruction, patients should maintainadequate hydration during and in the days following barium sulfateprocedure. Consider the administration of laxatives.. 5.4 Aspiration Pneumonitis. The use of E-Z-HD is contraindicatedin patients at high risk of aspiration [see Contraindications(4)]. Oral administrationof barium is associated with aspiration pneumonitis, especially inpatients with history of food aspiration or with compromised swallowingmechanism. Vomiting following oral administration of barium sulfatemay lead to aspiration pneumonitis. In patients at risk for aspiration,begin the procedure with small ingested volume of E-Z-HD. Discontinueadministration of E-Z-HD immediately if aspiration is suspected.. 5.5 SystemicEmbolization. Barium sulfate products may occasionally intravasate into the venousdrainage of the large bowel and enter the circulation as bariumembolus leading to potentially fatal complications which includesystemic and pulmonary embolism, disseminated intravascular coagulation,septicemia and prolonged severe hypotension. Although this complicationis exceedingly uncommon after oral administration of barium sulfatesuspension, monitor patients for potential intravasation when administeringbarium sulfate.. 5.6 Risk with Hereditary Fructose Intolerance. E-Z-HD containssorbitol which may cause severe reactions if ingested by patientswith hereditary fructose intolerance, such as: vomiting, hypoglycemia,jaundice, hemorrhage, hepatomegaly, hyperuricemia, and kidney failure. Before administration of E-Z-HD assess patients for history ofhereditary fructose intolerance and avoid use in these patients.
