Defnalone Tablet (Deflazacort) | Used for Arthritis and Autoimmune Diseases
Defnalone Tablet contains Deflazacort, a synthetic oxazoline corticosteroid derived from prednisolone, used to treat a broad range of inflammatory, allergic, and autoimmune conditions including rheumatic disorders, respiratory diseases, dermatological conditions, nephrotic syndrome, and Duchenne muscular dystrophy.
Product Overview
Defnalone Tablet is a high-potency synthetic glucocorticoid containing Deflazacort. It is engineered to provide powerful anti-inflammatory and immunosuppressive relief including rheumatic disorders, respiratory diseases, dermatological conditions, nephrotic syndrome, and Duchenne muscular dystrophy. As a derivative of prednisolone, it is specifically valued in clinical practice for its "steroid-sparing" characteristics, meaning it often achieves significant therapeutic results with a reduced impact on bone density and carbohydrate metabolism compared to older corticosteroids.
Product Composition
- Deflazacort: The active pharmaceutical ingredient (available in 6mg), providing systemic control over inflammatory pathways.
- Microcrystalline Cellulose: A high-purity excipient that serves as a filler and binder, ensuring the tablet remains stable and easy to handle.
- Magnesium Stearate: A pharmaceutical-grade lubricant that ensures the active drug is evenly distributed and released consistently.
- Croscarmellose Sodium: A cross-linked polymer that acts as a super-disintegrant, facilitating rapid tablet breakdown for faster drug onset.
- Purified Talc: Included to improve the texture of the tablet and prevent sticking during the compression process.

Mechanism of Action
- Defnalone exerts its effect by diffusing into target cells and binding to cytoplasmic glucocorticoid receptors.
- Once activated, this complex travels to the cell nucleus to modulate gene transcription, effectively turning off the production of proteins that cause swelling and pain.
- It significantly inhibits the release of inflammatory mediators like histamine, prostaglandins, and leukotrienes from mast cells and leukocytes.
- The medication suppresses the immune response by reducing the activity of T-lymphocytes and decreasing the production of antibodies.
- Unlike many other steroids, its molecular structure is designed to minimize interference with calcium absorption, which helps in preserving bone health during extended treatment.
Key Benefits
- Highly effective for the long-term management of Duchenne Muscular Dystrophy (DMD), helping to prolong muscle strength and mobility.
- Provides a safer alternative for patients who require steroids but are concerned about weight gain or developing steroid-induced diabetes.
- Excellent for treating severe asthma and chronic allergies by rapidly reducing airway inflammation and hyper-reactivity.
- Utilized in the treatment of autoimmune joint diseases, providing rapid relief from the stiffness and pain associated with rheumatoid arthritis.
- Offers a lower risk of growth suppression in pediatric patients compared to traditional corticosteroids like prednisone.
- Essential for managing dermatological flare-ups, including severe eczema and psoriasis, by calming the overactive immune response in the skin.
Precautions
| General Precaution | Details |
|---|---|
| Use only on prescription | Take Defnalone Tablet only as directed by a doctor |
| Do not stop suddenly | Abrupt stopping may cause withdrawal symptoms |
| Take with food | Helps reduce stomach irritation |
| Use lowest effective dose | Reduces risk of long-term side effects |
| Regular monitoring | May require routine medical check-ups |
Medical Supervision
- Always use under strict medical guidance
- Inform your doctor about existing infections or chronic illnesses
- Share history of diabetes, hypertension or bone disorders
Health Condition Precautions
- Use carefully in diabetes as it may increase blood sugar levels
- Caution in patients with high blood pressure
- May increase risk of infections due to immune suppression
- Long-term use may weaken bones and muscles
During Treatment Care
- Avoid exposure to people with infections
- Attend regular follow-up visits if used long term
- Report fever, weakness or unusual symptoms immediately
Pregnancy and Breastfeeding
- Use only if clearly prescribed by a doctor
- Doctor will assess risk vs benefit before use
Safety Advice
- Avoid alcohol if advised by your doctor
- Do not take live vaccines without medical approval
- Store in a cool, dry place away from moisture and heat
Usage
The administration of Defnalone must be tailored to the patient's specific condition, with careful consideration given to the timing and duration of the steroid therapy.
Administration
Diurnal Alignment: It is best to take the dose in the morning to mimic the body's natural peak of cortisol, which helps reduce the risk of adrenal suppression.
Gastric Protection: Tablets should be taken with food or milk to protect the stomach lining and reduce the chance of indigestion.
The Tapering Rule: If the medication has been taken for more than a few days, it must be gradually tapered off. Stopping abruptly can lead to "steroid withdrawal" or acute adrenal crisis.
Consistency: Take the medication at the same time every day to ensure a steady concentration of the active metabolite in the bloodstream.
Missed Dose: If a dose is missed, take it as soon as remembered unless it is almost time for the next dose; do not double the dose to catch up.
Clinical Guidance Summary
| Factor | Recommendation |
| Timing | Once daily, preferably in the morning |
| Interaction | Avoid taking with NSAIDs (like Aspirin) unless directed, as it increases ulcer risk |
| Monitoring | Regular checks for blood pressure, weight gain, and blood sugar |
| Infection Risk | Avoid contact with individuals who have chickenpox or measles while on therapy |
