Pantadexa (Dexamethasone Sodium Phosphate)

Dexamethasone Sodium Phosphate is used to manage inflammatory and immune‑mediated conditions.

• Inflammatory conditions: reduces swelling and pain by suppressing inflammatory mediators.
• Allergic reactions: mitigates severe hypersensitivity responses through immune modulation.
• Arthritis: alleviates joint inflammation and improves mobility.
• Autoimmune disorders: dampens overactive immune activity to control disease flares.

• Dexamethasone Sodium Phosphate binds intracellular glucocorticoid receptors, forming a complex that translocates to the nucleus and alters gene transcription. This leads to decreased production of pro‑inflammatory cytokines, inhibition of leukocyte migration, and suppression of immune cell activation, resulting in potent anti‑inflammatory and immunosuppressive effects.

Adverse reactions may occur with dexamethasone sodium phosphate therapy.

Common Side Effects

• Hyperglycemia: elevated blood sugar levels, especially in diabetic patients.
• Increased appetite and weight gain.
• Insomnia or sleep disturbances.
• Mood changes: irritability, anxiety, or euphoria.
• Gastrointestinal discomfort: nausea, dyspepsia.
• Injection‑site reactions: pain, erythema, or swelling.

Serious or Rare Side Effects

• Adrenal suppression: risk of adrenal insufficiency on abrupt discontinuation.
• Severe infection: heightened susceptibility to bacterial, viral, or fungal infections.
• Hypersensitivity: anaphylactic reactions including rash, bronchospasm.
• Osteonecrosis: bone tissue death, particularly in weight‑bearing joints.
• Cataracts or glaucoma: ocular pressure increase.
• Electrolyte imbalance: severe hypokalemia or sodium retention.

Before initiating therapy, clinicians should consider several safety measures.

• Assess infection risk: evaluate for active infections prior to use.
• Monitor blood glucose: patients with diabetes may require dose adjustments.
• Screen psychiatric history: glucocorticoids can exacerbate mood disorders.
• Use lowest effective dose: limit duration to reduce systemic exposure.
• Avoid abrupt discontinuation: taper under medical supervision.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Dexamethasone sodium phosphate may interact with other medicines.

Major Interactions (Avoid)

• Systemic CYP3A4 inhibitors: may raise dexamethasone concentrations.
• Live vaccines: increased risk of infection.
• Anticoagulants (e.g., warfarin): enhanced anticoagulant effect.

Moderate Interactions (Monitor Closely)

• Non‑steroidal anti‑inflammatory drugs: higher gastrointestinal ulcer risk.
• Antidiabetic agents: may need dose adjustment for hyperglycemia.
• Diuretics: potential for potassium loss.
