Introduction of Sodium diatrizoate hydrate is an iodinated, water-soluble contrast agent used in diagnostic imaging. Its structure features a benzene ring with three iodine atoms (providing X-ray opacity), two acetamido groups, and a sodium carboxylate group, enhancing solubility. Administered intravenously, orally, or rectally, it highlights blood vessels, urinary tracts, or gastrointestinal systems during X-rays or CT scans. A high-osmolar ionic agent, it carries risks like nephrotoxicity or allergic reactions, limiting its use compared to safer non-ionic alternatives. Still employed in specific GI studies (e.g., Gastrografin), it requires proper hydration and kidney function assessment. Store protected from light/moisture.

Application of Sodium diatrizoate hydrate is a pharmaceutical compound primarily used as an iodinated contrast agent in diagnostic radiology. Below is a detailed breakdown of its properties, structure, and applications:

Chemical Structure

Core Compound: Diatrizoic acid derivative (a triiodinated benzoic acid).

Structure:

A benzene ring substituted with:

Three iodine atoms (at positions 2, 4, and 6) for radiopacity.

Two acetamido groups (-NHCOCH?) at positions 3 and 5.

A carboxyl group (-COO?) at position 1, neutralized by a sodium ion (Na?).

Hydrate: Contains water molecules (H?O) in its crystalline lattice (exact stoichiometry varies).

IUPAC Name: Sodium 3,5-bis(acetylamino)-2,4,6-triiodobenzoate hydrate.

Key Properties

1. High Water Solubility: The sodium salt form enhances solubility, making it suitable for intravenous or oral administration.
2. Radiopacity: Contains ~60% iodine by weight, enabling strong X-ray absorption for imaging.
3. Osmolality: Classified as a high-osmolar contrast medium (HOCM), which may cause more side effects compared to newer low-osmolar agents.
4. Stability: The hydrate form ensures stability in solid-state storage but requires protection from light and moisture.

Applications

Diagnostic Imaging:

Angiography: Visualizes blood vessels.

Urography: Examines the urinary tract.

Gastrointestinal Studies: Used orally or rectally for GI tract imaging (e.g., barium substitute).

Administration: Typically administered intravenously, orally, or via enema, depending on the procedure.

Pharmacology & Safety

Mechanism: Iodine atoms absorb X-rays, creating contrast between tissues and fluids.

Excretion: Eliminated renally (unchanged) within 24 hours; requires normal kidney function.

Adverse Effects:

Mild: Nausea, flushing, or itching.

Severe: Anaphylaxis, nephrotoxicity (rare, but caution in renal impairment).

Contraindications: Allergy to iodine, severe renal dysfunction, or hyperthyroidism.

Comparison with Other Agents

High-Osmolar vs. Low-Osmolar: Sodium diatrizoate is an older ionic, high-osmolar agent (higher risk of adverse reactions). Newer non-ionic agents (e.g., iohexol, iopamidol) are safer but more expensive.

Brand Names: Historically marketed as Hypaque (in combination with meglumine diatrizoate) or Gastrografin (for GI use).

Storage

Store in airtight containers, protected from light and humidity.

Solutions are typically prepared just before use to avoid degradation.

Key Takeaway

Sodium diatrizoate hydrate is a legacy iodinated contrast agent valued for its radiopacity but limited by high osmolality. It remains in use for specific applications (e.g., GI imaging) but has largely been replaced by safer non-ionic alternatives in vascular studies.
