technetium (99mTc) gluconate

V09CA05

Forms & Strengths

Kit for the preparation of technetium Tc 99m gluconate injection

Adult Dosing

Intravenous injection of 185 to 370 MBq (5 to 10 mCi) of technetium Tc 99m gluconate
Imaging typically performed 1 to 2 hours post-injection

Pediatric Dosing

Dosing adjusted based on body surface area or weight according to nuclear medicine guidelines
Typically 3.7 to 7.4 MBq/kg with a minimum recommended dose

Indications

Renal scintigraphy and visualization of renal parenchyma
Evaluation of renal blood flow, function, and morphological abnormalities

Mechanism of Action

Technetium Tc 99m is bound to sodium gluconate and localizes in the renal cortex
Retained within the renal tubular cells and vascular spaces, allowing static imaging of renal parenchyma

Contraindications

Known hypersensitivity to technetium Tc 99m or gluconate preparations
Pregnancy, unless the clinical benefit outweighs the potential radiation risk
Lactation (breastfeeding should be interrupted for a specified period after administration)

Adverse Reactions

Hypersensitivity reactions including rash, pruritus, and urticaria (rare)
Injection site reactions such as pain or erythema
Nausea and dizziness (infrequent)

Drug Interactions

Drugs that significantly alter renal blood flow or function may affect radiopharmaceutical biodistribution
Prior administration of other renal imaging agents may cause interference
