Drug Guide

Generic Name

Ioversol

Brand Names Optiray 160, Optiray 240, Optiray 300, Optiray 320, Optiray 350

Classification

Therapeutic: Contrast Agent, Diagnostic

Pharmacological: Nonionic, iodinated radiopaque contrast agent

FDA Approved Indications

  • X-ray imaging of vascular system and body cavities where contrast enhancement is needed

Mechanism of Action

Ioversol is an iodinated contrast agent that increases the attenuation of X-rays in blood vessels and tissues, enhancing contrast in radiographic images.

Dosage and Administration

Adult: Dosage varies based on procedure; generally 50-150 mL administered via IV, with volume adjusted based on body habitus and imaging requirements.

Pediatric: Dosing is weight-based; consult specific protocols. Usually 1-2 mL/kg as a single dose.

Geriatric: Adjusted based on renal function; use caution in elderly patients due to risk of renal impairment.

Renal Impairment: Reduce dose and ensure adequate hydration; avoid in severe renal impairment if possible.

Hepatic Impairment: No specific adjustments, but caution advised.

Pharmacokinetics

Absorption: Not absorbed orally; administered intravenously.

Distribution: Rapidly distributes in extracellular fluid.

Metabolism: Excreted largely unchanged in urine.

Excretion: Primarily renal excretion.

Half Life: Approximately 2 hours in patients with normal renal function.

Contraindications

  • Known allergy to iodine or iodinated contrast media
  • History of severe hypersensitivity reactions to contrast agents

Precautions

  • Patients with renal impairment, asthma, or allergies to other contrast media should be carefully evaluated before administration.
  • Pre-medication may be considered in at-risk patients.

Adverse Reactions - Common

  • Nausea (Frequently)
  • Warm feeling or flushing (Common)
  • Pruritus or rash (Uncommon)

Adverse Reactions - Serious

  • Anaphylactic reactions (Rare)
  • Contrast-induced nephropathy (CIN) (Rare but serious)

Drug-Drug Interactions

  • Other nephrotoxic drugs (e.g., aminoglycosides, NSAIDs) increase risk of renal impairment

Drug-Food Interactions

Drug-Herb Interactions

Nursing Implications

Assessment: Assess for allergy history, renal function, and hydration status before administration.

Diagnoses:

  • Risk for allergic reaction
  • Risk for renal impairment

Implementation: Ensure proper hydration, monitor vital signs, and observe for allergic or adverse reactions during and after administration.

Evaluation: Monitor renal function post-procedure, reassess for allergic symptoms.

Patient/Family Teaching

  • Inform about possible sensations during injection (warmth, flushing).
  • Advise to report any allergic symptoms immediately.
  • Emphasize importance of hydration to reduce renal risk.

Special Considerations

Black Box Warnings:

  • Risk of anaphylaxis and hypersensitivity reactions.
  • Potential for contrast-induced nephropathy (CIN).

Genetic Factors: No specific genetic concerns identified.

Lab Test Interference: May interfere with thyroid function tests due to iodine content.

Overdose Management

Signs/Symptoms: Signs of hypersensitivity, renal impairment, or adverse reactions.

Treatment: Supportive care, treat allergic reactions with antihistamines or epinephrine, ensure adequate hydration, and renal support if necessary.

Storage and Handling

Storage: Store at controlled room temperature, 20°C to 25°C (68°F to 77°F).

Stability: Stable until expiration date when stored properly.
