Gadopentetic acid

Intravenous
Cranial, spinal and whole body imaging

Severe (GFR <30 mL/min/1.73 m²): Contraindicated.

Hypersensitivity. Acute kidney injury, patient in perioperative liver transplantation period. Severe renal impairment (GFR <30 mL/min/1.73 m²). Neonates <4 week.

Patient with history of allergic reactions, bronchial asthma, seizure disorders, intracranial lesions. Mild to moderate renal impairment. Children. Pregnancy and lactation.

Significant: Gadolinium retention, extravasation reactions (e.g. thrombosis, skin and soft tissue necrosis). Rarely, seizures.
Gastrointestinal disorders: Nausea, vomiting, dysgeusia.
Injury, poisoning and procedural complications: Inj site reactions (e.g. pain, oedema, irritation).
Nervous system disorders: Headache, dizziness.
Skin and subcutaneous tissue disorders: Hot or cold sensation.
Potentially Fatal: Nephrogenic systemic fibrosis. Rarely, hypersensitivity (e.g. anaphylactic reactions).

Parenteral: C

Monitor renal function prior to administration. Monitor for signs and symptoms of hypersensitivity reactions, extravasation, nephrogenic systemic fibrosis (e.g. muscle weakness, rib bone pain).

Falsely low value result with serum Fe determination test using complexometric methods.

Description:
Mechanism of Action: Gadopentetic acid is an ionic gadolimium chelate, paramagnetic contrast media for MRI. It shortens the relaxation time of water protons in the plasma leading to increase in signal intensity, thus enhancing the image contrast between tissues.
Pharmacokinetics:
Distribution: Rapidly distributed into the extracellular space. Crosses placenta and enters breast milk in small amount. Volume of distribution: Approx 0.266 ± 0.043 L/kg.
Excretion: Via urine (approx 91% as gadopentetate). Elimination half-life: 1.6 ± 0.13 hr.
