Administration

NOTE: Patients should be well hydrated prior to and after iopromide administration. A suggested common regimen in eligible patients (e.g., those patients in which fluid administration would not be contraindicated) is 1 mL/kg/hour of 0.9% Sodium Chloride Injection starting at least 4 hours prior to the procedure or exam and continuing for at least 12 hours after.
NOTE: In patients with a history of allergic reaction to contrast media or iodine, those with a history of asthma or allergic reactions to drugs or foods, nonionic contrast media should be used. In addition, consider administering prednisone 50 mg PO (or equivalent dose of other steroids) 13 hours, 7 hours, and 1 hour prior to the exam or procedure plus diphenhydramine 50 mg IM or PO 1 hour prior to the procedure. The administration of prophylactic steroids and antihistamines does not prevent all hypersensitivity reactions, but reduces the likelihood and may decrease the severity of the reaction.
NOTE: Individualize the volume, concentration, and injection rate of iopromide according to type of imaging procedure. Consider the age of the patient, patient's body weight, size of the vessel and its blood flow, pathology and degree and extent of opacification required, area to be examined, the patient's disease states, equipment and technique to be employed when determining the necessary dose. To minimize the risk of toxicity, ensure patients are adequately hydrated, and use the lowest necessary dose of iopromide.

Injectable Administration

Visually inspect parenteral products for particulate matter and discoloration prior to administration whenever solution and container permit. Do not administer if discoloration or particulate matter (including crystals) is observed or if container is defective.
Use aseptic technique for all handling and administration of iopromide.
The solution must be administered intravascularly (via intravenous or intra-arterial injection). Avoid inadvertent intrathecal administration.
Discard any unused portion remaining in the single-dose container after initial use.
Warm iopromide to body temperature prior to administration.
 
Iopromide Pharmacy Bulk Package (PBP):
Iopromide PBP is not for direct infusion.
Complete the transfer of the PBP in an appropriate work area (e.g., laminar flow hood) utilizing aseptic technique.
Puncture the container closure only 1 time, utilizing a suitable transfer device.
Discard any unused portion remaining in the PBP after 10 hours from initial puncture.
 
Iopromide Imaging Bulk Package (IBP):
Iopromide IBP is for intravenous use only.
Iopromide IBP is for use only with an automated contrast injection system, contrast management system, or contrast media transfer set approved or cleared for use with iopromide IBP. Refer to drug and device labeling for information on devices indicated for use with iopromide IBP and techniques to help assure safe use.
Only use the iopromide IBP in a room designated for radiological procedures that involve intravascular administration of a contrast agent.
Puncture the container closure of the IBP 1 time only using aseptic technique with a suitable sterile compartment of the automated contrast injection system, contrast management system, or contrast media transfer set approved or cleared for use with iopromide IBP.
Once the iopromide IBP is punctured, do not remove it from the work area during the entire period of use. Maintain the bottle in an inverted position so that the container contents are in continuous contact with the dispensing set.
After the container closure is punctured, discard the IBP and all associated disposables for the automated contrast injection system, contrast management system, or contrast media transfer set, if the integrity of the IBP and the delivery system cannot be assured through direct continuous supervision.
Discard any unused portion remaining in the IBP container after 10 hours from initial puncture.
Storage: storage temperature of iopromide IBP after the closure has been entered should not exceed 25 degrees C (77 degrees F) with excursions permitted to 15 degrees C to 30 degrees C (59 degrees F to 86 degrees F). Note: contents should be warmed to body temperature prior to injection.

Intravenous Administration

Do not mix or inject iopromide in intravenous administration lines containing other drugs or total nutritional admixtures. Iopromide may be mixed with 0.9% Sodium Chloride Injection when used in a powder injector suitable for simultaneous injection of contrast and 0.9% Sodium Chloride Injection.
Administer either by bolus injection or rapid infusion.

Other Injectable Administration

Intra-arterial Administration
Inject contrast at rates approximately equal to the flow rate in the vessel being injected.

Drug Interactions

Acebutolol: (Moderate) Use caution when administering non-ionic contrast media to patients taking beta-blockers. Beta-blockers lower the threshold for and increase the severity of contrast reactions and reduce the responsiveness of treatment of hypersensitivity reactions with epinephrine.
Acetaminophen; Aspirin, ASA; Caffeine: (Major) Use of medications that lower the seizure threshold should be carefully evaluated when considering intrathecal radiopaque contrast agents. Caffeine and caffeine containing products should be discontinued at least 48 hours before myelography and should not be resumed for at least 24 hours post-procedure.
Acetaminophen; Caffeine: (Major) Use of medications that lower the seizure threshold should be carefully evaluated when considering intrathecal radiopaque contrast agents. Caffeine and caffeine containing products should be discontinued at least 48 hours before myelography and should not be resumed for at least 24 hours post-procedure.
Acetaminophen; Caffeine; Dihydrocodeine: (Major) Use of medications that lower the seizure threshold should be carefully evaluated when considering intrathecal radiopaque contrast agents. Caffeine and caffeine containing products should be discontinued at least 48 hours before myelography and should not be resumed for at least 24 hours post-procedure.
Acetaminophen; Caffeine; Pyrilamine: (Major) Use of medications that lower the seizure threshold should be carefully evaluated when considering intrathecal radiopaque contrast agents. Caffeine and caffeine containing products should be discontinued at least 48 hours before myelography and should not be resumed for at least 24 hours post-procedure.
Acetaminophen; Chlorpheniramine; Dextromethorphan; Phenylephrine: (Major) Do not administer non-ionic contrast media intra-arterially after the administration of vasopressors since they strongly potentiate neurologic effects.
Acetaminophen; Chlorpheniramine; Phenylephrine : (Major) Do not administer non-ionic contrast media intra-arterially after the administration of vasopressors since they strongly potentiate neurologic effects.
Acetaminophen; Dextromethorphan; Guaifenesin; Phenylephrine: (Major) Do not administer non-ionic contrast media intra-arterially after the administration of vasopressors since they strongly potentiate neurologic effects.
Acetaminophen; Dextromethorphan; Phenylephrine: (Major) Do not administer non-ionic contrast media intra-arterially after the administration of vasopressors since they strongly potentiate neurologic effects.
Acetaminophen; Guaifenesin; Phenylephrine: (Major) Do not administer non-ionic contrast media intra-arterially after the administration of vasopressors since they strongly potentiate neurologic effects.
Acetaminophen; Phenylephrine: (Major) Do not administer non-ionic contrast media intra-arterially after the administration of vasopressors since they strongly potentiate neurologic effects.
Acyclovir: (Moderate) Concomitant use of acyclovir and contrast agents should be avoided when possible, as use of these drugs together may increase the risk for nephrotoxicity.
Aldesleukin, IL-2: (Moderate) Patients have reported 'recall reactions' of aldesleukin therapy and delayed reactions to contrast when used concomitantly with radiopaque contrast agents. The reactions responded to supportive therapy. Such recall reactions were minimized by using nonionic contrast media and waiting four weeks between aldesleukin treatment and radiopaque contrast agents.
Aliskiren; Hydrochlorothiazide, HCTZ: (Major) Do not use diuretics before non-ionic contrast media administration. Concomitant use of diuretics and non-ionic contrast media may increase the risk for acute kidney injury, including renal failure.
Alogliptin; Metformin: (Major) Discontinue metformin at the time of, or before, administration of non-ionic contrast media to patients with an eGFR of 30 to 60 mL/minute/1.73 m2, history of liver disease, alcoholism, or heart failure, or who will be administered intra-arterial iodinated contrast. Reevaluate eGFR 48 hours after the imaging procedure; restart metformin if renal function is stable. Iodinated contrast agents appear to increase the risk of metformin-induced lactic acidosis, possibly as a result of worsening renal function.
Amiloride: (Major) Do not use diuretics before non-ionic contrast media administration. Concomitant use of diuretics and non-ionic contrast media may increase the risk for acute kidney injury, including renal failure.
Amiloride; Hydrochlorothiazide, HCTZ: (Major) Do not use diuretics before non-ionic contrast media administration. Concomitant use of diuretics and non-ionic contrast media may increase the risk for acute kidney injury, including renal failure.
Aminoglycosides: (Moderate) Because the use of other nephrotoxic drugs, such as aminoglycoside antibiotics, is an additive risk factor for nephrotoxicity in patients receiving radiopaque contrast agents, concomitant use should be avoided when possible.
Amiodarone: (Major) When injected directly into coronary arteries, contrast media can cause bradycardia and QT interval prolongation; these reactions tend to be less common with nonionic low-osmolar contrast media. In a retrospective review of 21 patients on amiodarone therapy who underwent cardiac catheterization with iohexol, the QTc interval was significantly prolonged 12-24 hours post catheterization from a baseline QTc interval of 433 msec (95%CI 419-483 msec) to 480 msec (95%CI, 422-483 msec) (p< 0.001). No significant change in the QTc interval was seen in non-amiodarone treated control patients. Until more data are available, clinicians should closely monitor patients taking amiodarone during cardiac catheterization with radiopaque contrast agents; EKG monitoring during intra-coronary artery injection of radiopaque contrast agents is recommended.
Amitriptyline: (Major) Use of medications that lower the seizure threshold should be carefully evaluated when considering the use of intrathecal radiopaque contrast agents. Tricyclic antidepressants should be discontinued at least 48 hours before myelography and should not be resumed for at least 24 hours postprocedure.

Amphetamines should be discontinued at least 48 hours before myelography and should not be resumed for at least 24 hours postprocedure.
Amphetamine; Dextroamphetamine Salts: (Major) Use of medications that lower the seizure threshold should be carefully evaluated when considering the use of intrathecal radiopaque contrast agents. Amphetamines should be discontinued at least 48 hours before myelography and should not be resumed for at least 24 hours postprocedure.
Amphetamine; Dextroamphetamine: (Major) Use of medications that lower the seizure threshold should be carefully evaluated when considering the use of intrathecal radiopaque contrast agents. Amphetamines should be discontinued at least 48 hours before myelography and should not be resumed for at least 24 hours postprocedure.
Amphotericin B: (Moderate) Because the use of other nephrotoxic drugs, including amphotericin B, is an additive risk factor for nephrotoxicity in patients receiving radiopaque contrast agents, concomitant use should be avoided when possible.
Angiotensin II: (Major) Do not administer non-ionic contrast media intra-arterially after the administration of vasopressors since they strongly potentiate neurologic effects.
Angiotensin-converting enzyme inhibitors: (Moderate) Because the use of other nephrotoxic drugs, including ACE inhibitors, is an additive risk factor for nephrotoxicity in patients receiving radiopaque contrast agents, ACE inhibitor therapy should be withheld, when possible, during radiopaque contrast agent administration.
Aprotinin: (Moderate) The manufacturer recommends using aprotinin cautiously in patients that are receiving drugs that can affect renal function, such as radiopaque contrast agents, as the risk of renal impairment may be increased.
Aripiprazole: (Major) Aripiprazole lowers the seizure threshold and should be discontinued at least 48 hours before myelography and should not be resumed for at least 24 hours postprocedure.
Articaine; Epinephrine: (Major) Do not administer non-ionic contrast media intra-arterially after the administration of vasopressors since they strongly potentiate neurologic effects.
Asenapine: (Major) Use of medications that lower the seizure threshold should be carefully evaluated when considering intrathecal radiopaque contrast agents. Antipsychotics should be discontinued at least 48 hours before myelography and should not be resumed for at least 24 hours post-procedure. The frequency of seizure activity with asenapine was low during clinical trials; however, seizures have been associated with other antipsychotics and caution is advised.
Aspirin, ASA; Butalbital; Caffeine: (Major) Use of medications that lower the seizure threshold should be carefully evaluated when considering intrathecal radiopaque contrast agents. Caffeine and caffeine containing products should be discontinued at least 48 hours before myelography and should not be resumed for at least 24 hours post-procedure.
Aspirin, ASA; Caffeine: (Major) Use of medications that lower the seizure threshold should be carefully evaluated when considering intrathecal radiopaque contrast agents.

Betaxolol: (Moderate) Use caution when administering non-ionic contrast media to patients taking beta-blockers. Beta-blockers lower the threshold for and increase the severity of contrast reactions and reduce the responsiveness of treatment of hypersensitivity reactions with epinephrine.
Bictegravir; Emtricitabine; Tenofovir Alafenamide: (Moderate) Monitor for changes in renal function if tenofovir alafenamide is administered in combination with nephrotoxic agents, such as radiopaque contrast agents. Tenofovir is primarily excreted via the kidneys by a combination of glomerular filtration and active tubular secretion. Coadministration of tenofovir alafenamide with a drug that reduces renal function or competes for active tubular secretion may increase concentrations of tenofovir and other renally eliminated drugs; thus, increasing the risk of developing renal-related adverse reactions.
Bisoprolol: (Moderate) Use caution when administering non-ionic contrast media to patients taking beta-blockers. Beta-blockers lower the threshold for and increase the severity of contrast reactions and reduce the responsiveness of treatment of hypersensitivity reactions with epinephrine.

Pamidronate: (Moderate) Coadministration of pamidronate with other nephrotoxic drugs may increase the risk of developing nephrotoxicity following pamidronate administration, even in patients who have normal renal function.
Perphenazine; Amitriptyline: (Major) Use of medications that lower the seizure threshold should be carefully evaluated when considering the use of intrathecal radiopaque contrast agents. Tricyclic antidepressants should be discontinued at least 48 hours before myelography and should not be resumed for at least 24 hours postprocedure.
Phendimetrazine: (Major) Phendimetrazine lowers the seizure threshold and should be discontinued at least 48 hours before and for at least 24 hours after intrathecal use of contrast media.
Phenothiazines: (Major) Use of medications that lower the seizure threshold should be carefully evaluated when considering the use of intrathecal radiopaque contrast agents. Phenothiazines should be discontinued at least 48 hours before myelography and should not be resumed for at least 24 hours postprocedure.

Concomitant use of diuretics and non-ionic contrast media may increase the risk for acute kidney injury, including renal failure. (Moderate) Use caution when administering non-ionic contrast media to patients taking beta-blockers. Beta-blockers lower the threshold for and increase the severity of contrast reactions and reduce the responsiveness of treatment of hypersensitivity reactions with epinephrine.
Protriptyline: (Major) Use of medications that lower the seizure threshold should be carefully evaluated when considering the use of intrathecal radiopaque contrast agents. Tricyclic antidepressants should be discontinued at least 48 hours before myelography and should not be resumed for at least 24 hours postprocedure.

Sodium Iodide: (Moderate) Administration of non-ionic contrast media may interfere with thyroid uptake of radioactive sodium iodide (I-131) and decrease therapeutic and diagnostic efficacy in patients with carcinoma of the thyroid. The decrease in efficacy lasts for 6 to 8 weeks.
Sodium Oxybate: (Major) Sodium oxybate lowers seizure threshold and should be discontinued at least 48 hours before myelography and should not be resumed for at least 24 hours postprocedure.
Sotalol: (Moderate) Use caution when administering non-ionic contrast media to patients taking beta-blockers. Beta-blockers lower the threshold for and increase the severity of contrast reactions and reduce the responsiveness of treatment of hypersensitivity reactions with epinephrine.
Spironolactone: (Major) Do not use diuretics before non-ionic contrast media administration. Concomitant use of diuretics and non-ionic contrast media may increase the risk for acute kidney injury, including renal failure.
Spironolactone; Hydrochlorothiazide, HCTZ: (Major) Do not use diuretics before non-ionic contrast media administration. Concomitant use of diuretics and non-ionic contrast media may increase the risk for acute kidney injury, including renal failure.
Telmisartan; Hydrochlorothiazide, HCTZ: (Major) Do not use diuretics before non-ionic contrast media administration. Concomitant use of diuretics and non-ionic contrast media may increase the risk for acute kidney injury, including renal failure.
Tenofovir Alafenamide: (Moderate) Monitor for changes in renal function if tenofovir alafenamide is administered in combination with nephrotoxic agents, such as radiopaque contrast agents. Tenofovir is primarily excreted via the kidneys by a combination of glomerular filtration and active tubular secretion. Coadministration of tenofovir alafenamide with a drug that reduces renal function or competes for active tubular secretion may increase concentrations of tenofovir and other renally eliminated drugs; thus, increasing the risk of developing renal-related adverse reactions.
Tenofovir Alafenamide: (Moderate) Monitor for changes in renal function if tenofovir alafenamide is administered in combination with nephrotoxic agents, such as radiopaque contrast agents. Tenofovir is primarily excreted via the kidneys by a combination of glomerular filtration and active tubular secretion. Coadministration of tenofovir alafenamide with a drug that reduces renal function or competes for active tubular secretion may increase concentrations of tenofovir and other renally eliminated drugs; thus, increasing the risk of developing renal-related adverse reactions.
Tenofovir Disoproxil Fumarate: (Moderate) Tenofovir-containing products should be avoided with concurrent or recent use of a nephrotoxic agent, such as radiopaque contrast agents. Tenofovir is primarily excreted via the kidneys by a combination of glomerular filtration and active tubular secretion. Coadministration of tenofovir with drugs that are eliminated by active tubular secretion may increase concentrations of tenofovir and/or the co-administered drug. Drugs that decrease renal function may also increase concentrations of tenofovir. Renal impairment, which may include hypophosphatemia, has been reported with the use of tenofovir with a majority of the cases occurring in patients who have underlying systemic or renal disease or who are concurrently taking nephrotoxic agents. Monitor patients receiving concomitant nephrotoxic agents for changes in serum creatinine and phosphorus.

Tricyclic antidepressants should be discontinued at least 48 hours before myelography and should not be resumed for at least 24 hours postprocedure.
Valacyclovir: (Moderate) Concomitant use of valacyclovir and contrast agents should be avoided when possible, as use of these drugs together may increase the risk for nephrotoxicity.
Valsartan; Hydrochlorothiazide, HCTZ: (Major) Do not use diuretics before non-ionic contrast media administration. Concomitant use of diuretics and non-ionic contrast media may increase the risk for acute kidney injury, including renal failure.
Vasopressin, ADH: (Major) Do not administer non-ionic contrast media intra-arterially after the administration of vasopressors since they strongly potentiate neurologic effects.
Vasopressors: (Major) Do not administer non-ionic contrast media intra-arterially after the administration of vasopressors since they strongly potentiate neurologic effects.
Voclosporin: (Moderate) Concomitant use of voclosporin and non-ionic contrast media may result in additive nephrotoxicity. Monitor for renal toxicity if concomitant use is required.

Mechanism Of Action

Intravascular administration of iopromide opacifies vessels where the contrast agent is present which allows for radiographic visualization of the internal structures through attenuation of photons. Iodinated contrast agents diffuse from the vessels into the extravascular space in imaging of the body. Contrast does not diffuse into the extravascular space in a normal brain with an intact blood-brain barrier. In persons with a disrupted blood-brain barrier, contrast accumulates in the extravascular space in the region of disruption. The degree of contrast enhancement from iopromide is related to the iodine concentration in the tissue of interest.

Pharmacokinetics

Iopromide is administered by intravenous or intra-arterial injection. After intravascular injection, iopromide is immediately distributed into circulating blood volume. Iopromide then distributes into the interstitial space; after equilibrium, distribution into extracellular space occurs. The volume of distribution at steady-state is approximately 16 L. Iopromide is not significantly bound to plasma proteins (1%), and normally does not cross the blood-brain barrier. However, in persons with a disrupted blood-brain barrier or in some persons with normal blood-brain barriers and renal impairment, iopromide can accumulate in the brain. Iopromide does not undergo any significant metabolism, deiodination, or biotransformation and is primarily eliminated unchanged via glomerular filtration (97%); fecal elimination is negligible (2%). The mean total and renal clearances are 107 mL/minute and 104 mL/minute, respectively. The main elimination phase half-life is 2 hours, and the terminal elimination phase half-life is 6.2 hours.
 
Affected cytochrome P450 isoenzymes and drug transporters: none

Intravenous Route

Enhanced visualization of tissues by contrast media is directly related to the vascularization of the specific tissue. Visualization of the renal parenchyma occurs within 30 to 60 seconds after rapid intravenous injection of iopromide. The calyces and pelves can be visualized within 1 to 3 minutes, with optimal contrast occurring after 5 to 15 minutes. Maximum contrast enhancement during computed tomography brain imaging can occur up to 1 hour after injection depending on the type of lesion to be visualized. Contrast enhancement during computed tomography of the body appears to be greatest soon after bolus administration of the contrast medium (15 to 120 seconds). The greatest enhancement may be detected by a series of consecutive 2 to 3 second scans (e.g., dynamic computed tomography imaging) performed within 30 to 90 seconds after injection.

Pregnancy And Lactation
Pregnancy

There are no data on iopromide use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Limited case reports demonstrate that intravenously administered iodinated contrast agents, including iopromide, cross the placenta and are visualized in the digestive tract of exposed infants after birth. In animal reproduction studies, no adverse effects were noted in rats and rabbits at doses up to 3.7 g iodine/kg (approximately 0.7 times the human dose after normalization of the data to body surface area estimates). Due to the potential risks to the fetus, the American College of Radiology (ACR) recommends iodinated contrast agents be administered during pregnancy only if necessary and only after informed consent is obtained. In contrast, the Guidelines for Computed Tomography and Magnetic Resonance Imaging in Pregnancy and Lactation state that use of iodinated contrast during pregnancy appears to be safe and may be administered as per usual. It is advised to screen neonates whose mother received iodinated contrast during pregnancy for hypothyroidism.[49613] [49618] [49974]

There are no data on the excretion of iopromide in human milk, the effects on the breast-fed infant, or the effects on milk production. Iodinated contrast agents are poorly excreted into human milk and are poorly absorbed by the gastrointestinal tract of the breast-fed infant. Interruption of breast-feeding after exposure to iodinated contrast agents is not necessary because the potential exposure of the breast-fed infant to iodine is small. However, a lactating woman may consider interrupting breast-feeding and pumping and discarding breast milk for 12 to 24 hours (approximately 5 elimination half-lives) after iopromide administration in order to minimize drug exposure to the breast-fed infant. The Guidelines for Computed Tomography and Magnetic Resonance Imaging Use During Pregnancy and Lactation and the American College of Radiology (ACR) manual on contrast media also state that lactating women receiving iodinated contrast can continue breast-feeding without interruption. The reasoning for this recommendation is based on estimates of limited systemic exposure in breast-fed infants and reviews that conclude maternally administered iodinated contrast pose no risk to nursing infants.[49613] [49618] [49974]
