Description

Metrizamide is a glucosamine derivative of metrazoic acid, used as a contrast medium for myelography. Metrizamide is no longer marketed in the US.

CNS Activity

CNS Non-penetrant
1040
Curator's Comment: The blood-brain barrier of rats is impermeable to metrizamide.

Originator

Almen, T.|Nyegaard

Sample Use Guides

In Vivo Use Guide
300 mgI/ml as one injection
Route of Administration: Intra-arterial
In Vitro Use Guide
Cultured endothelial cells derived from human umbilical cord veins were labeled with Na2 (51Cr)O4 and exposed to pure isoiodinated contrast media or control solutions for 10 minutes to simulate the effects of intravenous injections of contrast media on the human endothelium. Metrizamide was used at 300 mgI/ml.
