Iobenguane I-123 is transported into adrenergic nerve terminals via the noradrenaline uptake transporter. It is rapidly cleared from systemic circulation and collected in adrenergically invervated tissues. This allows for gamma-scintigraphic imaging of these tissues and their associated organs for diagnostic purposes.

IOBENGUANE SULFATE I-123

Established Pharmacologic Class [EPC] - Radioactive Diagnostic Agent

Mechanisms of Action [MoA] - Radiopharmaceutical Activity

Iobenguane sulfate i-123 is a Radioactive Diagnostic Agent. The mechanism of action of iobenguane sulfate i-123 is as a Radiopharmaceutical Activity.

Primarily eliminated via the urine as the parent compound (70-90%). A small amount is eliminated in the urine as m-iodohippuric acid (</10%) and free radioiodide (</6%). Less than 1% is eliminated in the feces. Iobenguane I-123 is initially rapidly cleared from circulation follwed by a slow clearance from other tissues over 4 days. Retention is the longest in highly adrenergically inervated tissues like the adrenal medulla, heart, and salivary glands. Iobenguane I-123 is not cleared by dialysis.
