2 DOSAGE AND ADMINISTRATION Individualize the combination of volume and concentration of iodixanol injection considering age, body weight, size of the vessel, rate of blood flow within the vessel, and other applicable factors. ( 2.1 , 2.2 , 2.3 , 2.4 ) For CT of the head and body, iodixanol injection may be used with an automated contrast injection system or contrast media management system cleared for use with iodixanol injection. (2.5) For the adult patients, the maximum recommended total dose of iodine is 80 grams. ( 2.1 ) Patients should be adequately hydrated prior to and following the intravascular administration of iodinated contrast agents. ( 2.1 , 5.3 ) See full prescribing information for complete dosing and administration information. (2) 2.1 Important Dosage and Administration Instructions Iodixanol injection is for intravascular use only [see Boxed Warning , Contraindications (4) , and Warnings and Precautions (5.1) ] Use sterile technique for all handling and administration of iodixanol injection. Do not use if tamper-evident ring is broken or missing. Warm iodixanol injection and administer at body or room temperature. Inspect iodixanol injection for particulate matter or discoloration before administration, whenever solution and container permit. Do not administer if iodixanol injection contains particulate matter or is discolored. Do not mix iodixanol injection with, or inject in intravenous lines containing, other drugs or total nutritional admixtures. Use the lowest dose necessary to obtain adequate visualization. Individualize the volume, strength, and rate of administration of iodixanol injection. Consider factors such as age, bodyweight, vessel size, blood flow rate within the vessel, anticipated pathology, degree and extent of opacification required, structures or area to be examined, disease processes affecting the patient, and equipment and technique to be employed. The maximum recommended total dose of iodine for adults is 80 grams. Avoid extravasation when injecting iodixanol injection; especially in patients with severe arterial or venous disease [see Warnings and Precautions (5.6) ] . Hydrate patients before and after iodixanol injection administration [see Warnings and Precautions (5.3) ] . 2.2 Intra-arterial Dosage and Administration Intra-arterial digital subtraction angiography (IA-DSA) (270 mg Iodine/mL and 320 mg Iodine/mL) Angiocardiography (left ventriculography and selective coronary arteriography), peripheral arteriography, visceral arteriography, and cerebral arteriography (320 mg Iodine/mL) Use injection rates approximately equal to the flow rate in the vessel being injected. The usual single injection volumes or total dose per patient (mL/kg) for adults and adolescents over 12 years of age are listed in Table 1: TABLE 1 ADULTS and PEDIATRIC PATIENTS 12 YEARS OF AGE AND OLDER IODIXANOL INJECTION SINGLE DOSE RECOMMENDATIONS FOR INJECTION INTO SELECTED ARTERIES ARTERIOGRAPHY IA-DSA1 Maximum Total Dose Intra-arterial Injection Sites 320 mg Iodine/mL 270 mg Iodine/mL 320 mg Iodine/mL Carotid Arteries 10 mL to 14 mL 5 mL to 8 mL Usually Not to Exceed 175 mL Vertebral Arteries 10 mL to 12 mL 5 mL to 8 mL Right Coronary Artery 3 mL to 8 mL Usually Not to Exceed 200 mL Left Coronary Artery 3 mL to 10 mL Left Ventricle 20 mL to 45 mL Renal Arteries 8 mL to 18 mL 10 mL to 25 mL -- Usually Not to Exceed 250 mL Aortography 30 mL to 70 mL 20 mL to 50 mL 10 mL to 50 mL Major Branches of Aorta 10 mL to 70 mL 5 mL to 30 mL 2 mL to 10 mL Aortofemoral Runoffs 20 mL to 90 mL -- 6 mL to 15 mL Peripheral Arteries 15 mL to 30 mL -- 3 mL to 15 mL 1 IA-DSA = Intra-arterial Digital Subtraction Angiography 2.3 Intravenous Dosage and Administration Computed Tomography of the Head or Body (270 mg Iodine/mL and 320 mg Iodine/mL) Excretory Urography (270 mg Iodine/mL and 320 mg Iodine/mL) Peripheral Venography (270 mg Iodine/mL) Coronary Computed Tomography Angiography (CCTA) (320 mg Iodine/mL) Recommended dosage of iodixanol injection is dependent on: the administration procedure, patient weight, and CT device factors, as detailed in Table 2. Calibrate the intravenous injection rate so that image acquisition coincides with peak arterial concentration. The time between iodixanol injection and peak arterial concentration varies between patients. Selected dosing for different indications in adults and pediatric patients over 12 years of age are shown in Table 2 .

Iodixanol is often associated with sensations of discomfort, warmth or pain. In a subgroup of 1,259 patients; 30% who received iodixanol or a comparator had application site discomfort, pain, warmth or cold. Iodixanol had a trend toward fewer patient reports of moderate or severe pain or warmth. Pain was reported in 2% of patients receiving iodixanol and 10% of patients receiving a comparator. Heat was reported in 29% of patients receiving iodixanol and 51% of patients receiving a comparator. Table 3 shows the incidence of events reported in blinded, controlled clinical studies of iodixanol in a total of 1,244 adult patients. Adverse events (AEs) are listed by body system and in decreasing order of occurrence greater than 0.5% of patients. One or more adverse events were reported in 20% of patients during the study period (24 to 72 hours). In a 757 patient subgroup, the number of women reporting adverse events was 83/299 (28%) and the number of men was 77/458 (16%). A total of 3% of women and 0.8% of men reported chest pain.

Additional safety data was obtained in studies of iodixanol in 459 pediatric patients. A total of 26 patients ranged in age from birth to <29 days, 148 ranged from 29 days to 2 years, 263 from 2 to <12 years, and 22 from 12 to 18 years. A total of 252 (55%) of the patients were male. The racial distribution was: Caucasian-81%, Black-14%, Oriental-2%, and other or unknown-4%. The proportion of patients undergoing an intra-arterial procedure by age was: 92 % (<29 days), 55% (29 days to 6 months), and 29 % (>6 months). In these studies, adverse events were numerically higher in pediatric patients less than one year of age compared to older pediatric patients. In pediatric patients who received intravenous injections of iodixanol for computerized tomography or excretory urography, a concentration of 270 mg Iodine/mL was used in 144 patients, and a concentration of 320 mg Iodine/mL in 154 patients. All patients received one intravenous injection of 1 mL/kg to 2 mL/kg. In pediatric patients who received intra-arterial and intracardiac studies, a concentration of 320 mg Iodine/mL was used in 161 patients. Twenty-two patients were <29 days of age; 78 were 29 days to 2 years of age; and 61 were over 2 years. Most of these pediatric patients received initial volumes of 1 mL/kg to 2 mL/kg and most patients received a maximum of 3 injections.

12.3 Pharmacokinetics Distribution In an in vitro human plasma study, iodixanol did not bind to protein. The volume of distribution in adults was 0.26 L/kg body weight, consistent with distribution to extracellular space. Elimination In 40 healthy, young male volunteers receiving a single intravenous administration of iodixanol in doses of 0.3 gram Iodine/kg to 1.2 gram Iodine/kg body weight, the elimination half-life was 2.1 hr. (± 0.1). Renal clearance was 110 ± 14 mL/min, equivalent to glomerular filtration (108 mL/min). These values were independent of the dose administered. Metabolism Iodixanol does not undergo metabolism. Excretion In adults, approximately 97% of the injected dose of iodixanol is excreted unchanged in urine within 24 hours, with less than 2% excreted in feces within five days post-injection. Specific Populations Pediatric: Forty pediatric patients ≤12 years old, with renal function that is normal for their age, received multiple intra-arterial administrations of iodixanol in doses of 0.32 gram Iodine/kg to 3.2 gram Iodine/kg body weight. The elimination half-lives for these patients are shown in Table 5. Dose adjustments to account for differences in elimination half-life in pediatric patients less than 6 months of age have not been studied. TABLE 5 MEAN ELIMINATION HALF-LIFE* IN PEDIATRIC PATIENTS Age Range Number of Patients Elimination half-life (hr. ± SD) Newborn to < 2 months 8 4.1 ± 1.4 2 to 6 months 8 2.8 ± 0.6 6 to 12 months 9 2.4 ± 0.4 1 to 2 years 5 2.3 ± 0.6 2 to 12 years 10 2.3 ± 0.5 Adults 40 2.1 ± 0.1 Renal Impairment: In patients with significantly impaired renal function, the total clearance of iodixanol is reduced and the half-life is increased. In a study of 16 adult patients who were scheduled for renal transplant, the mean creatinine clearance was 13.6 ± 4.7 mL/min). In these patients, plasma half-life was 23 hours (t 1/2 for typical patients = 2.1 hours). Contrast enhancement time in kidneys increased from 6 hours to at least 24 hours. Dose adjustments in patients with renal impairment have not been studied. In patients with normal blood brain barriers and severe renal impairment, iodinated contrast agents have been associated with blood-brain barrier disruption and accumulation of contrast in the brain. Iodixanol has been shown to be dialyzable. In an in vitro hemodialysis study, after 4 hours of dialysis with a cellulose membrane, approximately 36% of iodixanol was removed from the plasma. After 4 hours of dialysis with polysulfone membranes, approximately 49% of iodixanol was removed.
