Medi-Exametazim

Exametazime, the active ingredient in Medi-Exametazim, is a radiopharmaceutical presented as a solution for injection for intravenous use. It is employed to label leukocytes with technetium‑99m, enabling gamma‑camera imaging that helps detect infection and inflammation in patients suspected of these conditions.

GNH USA supplies Medi-Exametazim as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals worldwide.

Medi-Exametazim is used in diagnostic imaging to visualize infection‑related processes and inflammatory sites.

- Detection of infection: enables visualization of active bacterial or fungal infections through labeled leukocyte accumulation. - Detection of inflammation: highlights inflammatory foci such as autoimmune or traumatic inflammation. - Leukocyte scintigraphy: provides whole‑body imaging of radiolabeled leukocytes to assess disease distribution and severity.

Adverse reactions may occur following intravenous administration of the radiopharmaceutical.

Common Side Effects: - Injection site pain or erythema - Transient nausea or vomiting - Mild headache or dizziness - Flushing or warmth sensation - Temporary hypotension - Mild allergic skin rash

Serious or Rare Side Effects: - Anaphylactic reaction or severe hypersensitivity - Severe hypotension or cardiovascular collapse - Pulmonary embolism from micro‑clots - Significant radiation‑induced tissue injury - Acute hemolysis or severe leukopenia

Use of Medi-Exametazim requires careful clinical assessment and adherence to radiopharmacy standards.

- Verify indication: confirm that leukocyte scintigraphy is clinically indicated. - Radiopharmacy preparation: ensure preparation is performed by qualified personnel under aseptic conditions. - Allergy check: assess patient history for hypersensitivity to radiopharmaceuticals or technetium‑99m. - Monitor vitals: observe blood pressure, heart rate, and respiratory status during and after injection. - Radiation safety: apply appropriate shielding and limit exposure to staff and family members. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Exametazime may interact with other agents that influence leukocyte function or radiopharmaceutical distribution.

Major Interactions (Avoid): - Concurrent administration of other technetium‑99m labeled agents that could compete for binding sites. - High‑dose corticosteroids that markedly suppress leukocyte migration.

Moderate Interactions (Monitor Closely): - Immunosuppressive drugs (e.g., azathioprine, methotrexate) that may alter labeling efficiency. - Iodinated contrast media used shortly before or after injection, potentially affecting image quality. - Antihistamines that could mask early allergic signs.
