Opnol (Dexamethasone Sodium Phosphate)

Dexamethasone sodium phosphate, the active ingredient in Opnol, is a corticosteroid presented as a sterile injectable solution for intravenous use. It reduces inflammation and modulates immune responses in a range of acute and chronic conditions.\n\nGNH India supplies Opnol as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, transplant centres, oncology centres, pharmacies and clinics worldwide.

Dexamethasone sodium phosphate is employed in the management of inflammatory and immune‑mediated disorders.\n\n- Severe allergic reactions: rapid reduction of airway swelling and systemic symptoms.\n- Cerebral edema: decreases intracranial pressure associated with tumors or trauma.\n- Acute inflammatory conditions: alleviates pain and swelling in severe arthritis or postoperative states.\n- Certain hematologic malignancies: part of chemotherapy regimens to control inflammation and improve response.

Adverse reactions may vary in frequency and severity.\n\nCommon Side Effects:\n- Elevated blood glucose levels.\n- Increased susceptibility to infections.\n- Mood changes such as anxiety or depression.\n- Gastrointestinal discomfort or ulceration.\n\nSerious or Rare Side Effects:\n- Adrenal suppression causing cortisol deficiency.\n- Severe hypersensitivity reactions including anaphylaxis.\n- Osteonecrosis of the jaw or avascular necrosis.\n- Thromboembolic events such as deep vein thrombosis.

Use of dexamethasone requires careful monitoring and patient education.\n\n- Assess infection risk: screen for active infections before initiating therapy.\n- Monitor blood glucose: adjust diabetic management as hyperglycaemia may occur.\n- Evaluate bone health: consider calcium and vitamin D supplementation for long‑term use.\n- Caution in pregnancy: weigh potential fetal risks against maternal benefits.\n- Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Dexamethasone can alter the pharmacokinetics or pharmacodynamics of several drugs.\n\nMajor Interactions (Avoid):\n- CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin): may increase dexamethasone exposure and toxicity.\n- Live vaccines: concurrent use can diminish vaccine efficacy and increase infection risk.\n\nModerate Interactions (Monitor Closely):\n- Anticoagulants (e.g., warfarin): dexamethasone may enhance anticoagulant effect, requiring INR monitoring.\n- Non‑steroidal anti‑inflammatory drugs (NSAIDs): combined use raises risk of gastrointestinal ulceration.\n- Diuretics: may potentiate electrolyte disturbances, especially hypokalaemia.
