1. Clinical Overview
Adrenochrome Monosemicarbazone is a hemostatic agent derived from the oxidation product of epinephrine. It acts as a capillary stabilizer and is primarily used in India for the management of capillary bleeding, particularly in ophthalmic and ENT surgeries, and in conditions involving increased capillary fragility. It is not a systemic coagulant but works by reducing capillary permeability and promoting platelet adhesion at the endothelial level.
| Onset | Duration | Bioavailability |
|---|---|---|
| Within 30 to 60 minutes after intramuscular injection. | Approximately 4 to 6 hours. | Not well characterized orally; primarily administered via intramuscular or intravenous routes where bioavailability is considered 100%. |
2. Mechanism of Action
Adrenochrome Monosemicarbazone stabilizes the capillary wall by interacting with the intercellular cement substance (hyaluronic acid) and reducing abnormal capillary permeability. It does not affect blood coagulation factors, prothrombin time, or platelet count. Its action is primarily on the vascular endothelium, promoting platelet adhesion and reducing the time for capillary hemostasis.
3. Indications & Uses
- Prophylaxis and treatment of capillary bleeding in ophthalmic surgery (e.g., cataract, glaucoma procedures)
- Control of capillary oozing in ENT surgeries (e.g., tonsillectomy, adenoidectomy, nasal surgeries)
- Management of increased capillary fragility as seen in conditions like hereditary hemorrhagic telangiectasia (for minor bleeds).
4. Dosage & Administration
Adult Dosage: 1 ampoule (40mg) intramuscularly or slow intravenous injection, 1 to 3 times daily as per surgical need. In surgical settings, often given pre-operatively and/or post-operatively.
Administration: For IM use: Administer by deep intramuscular injection. For IV use: Administer as a slow intravenous injection over 2-3 minutes. Do not mix with other medications in the same syringe. Inspect solution for particulate matter or discoloration before use.
5. Side Effects
Common side effects may include:
- Pain or discomfort at the injection site.
- Transient nausea.
6. Drug Interactions
| Drug | Effect | Severity |
|---|---|---|
| Anticoagulants (Warfarin, DOACs) | Theoretical reduction in efficacy of Adrenochrome. No direct pharmacodynamic interaction, but concurrent use for different bleeding risks requires monitoring. | Moderate |
| Anti-platelet drugs (Aspirin, Clopidogrel) | May antagonize the capillary stabilizing effect of Adrenochrome in controlling oozing. | Moderate |
| Antihypertensives | No significant interaction reported. | Minor |
7. Patient Counselling
- Do report any signs of allergic reaction like rash, itching, or swelling immediately.
- Do inform your surgeon and anesthetist that you are on this medication.
- Don't use this medicine for any bleeding without consulting a doctor.
- Don't stop or change the dosage schedule on your own.
8. Toxicology & Storage
Overdose: Symptoms are not well documented due to rarity. Theoretical symptoms based on pharmacology include severe nausea, vomiting, tachycardia, hypertension, anxiety, and risk of thrombotic events. Methemoglobinemia is a concern with massive overdose.
Storage: Store below 25°C. Protect from light. Do not freeze. Keep the ampoules in the outer carton. Keep out of reach of children. The solution should be clear; discard if cloudy or discolored.
