Medi-Macro

Human Albumin As Macroaggregates, the active ingredient in Medi-Macro, is a Biologic presented as a solution for injection for intravenous use. It is employed as a tracer in lung perfusion imaging, primarily for adult patients undergoing ventilation/perfusion (V/Q) scans to assess pulmonary blood flow.

GNH USA supplies Medi-Macro as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to EU GMP standards and provides cold‑chain logistics for biologic injectables. Customers receive regulatory documentation and support for import clearance.

Medi-Macro is used in nuclear medicine for pulmonary perfusion assessment. - Lung perfusion imaging: provides quantitative assessment of regional pulmonary blood flow. - Ventilation/perfusion (V/Q) scan: enables detection of pulmonary embolism by comparing ventilation and perfusion patterns. - Pre‑operative evaluation: assists in evaluating lung function before thoracic surgery.

Common Side Effects: - Transient dyspnea: short‑lasting shortness of breath after injection. - Chest discomfort: mild pain or pressure in the chest area. - Mild fever: low‑grade temperature elevation. - Injection site erythema: redness at the site of administration.

Serious or Rare Side Effects: - Anaphylactic reaction: severe allergic response requiring immediate medical attention. - Pulmonary embolism: macroaggregate lodging causing a perfusion defect. - Severe hypotension: marked drop in blood pressure following administration.

Prior to administration, consider the following precautions: - Allergy assessment: verify no known hypersensitivity to human albumin. - Patient condition: ensure appropriate indication and assess pulmonary status. - Aseptic technique: maintain sterility during preparation and injection. - Monitoring: observe vital signs during and after injection for adverse reactions. - Contraindication: avoid use in patients with severe pulmonary hypertension. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Medi-Macro may interact with other agents used in diagnostic imaging or affecting pulmonary circulation. Major Interactions (Avoid): - Concurrent radiopharmaceuticals: may interfere with image interpretation. - High‑dose anticoagulants: can alter macroaggregate distribution. - Severe anemia: may affect tracer uptake and imaging quality. Moderate Interactions (Monitor Closely): - Beta‑blockers: may modify heart rate monitoring during scans. - Diuretics: can change pulmonary capillary pressure and affect distribution. - Iodinated contrast agents: may impact subsequent nuclear imaging results.
