Can Deflazacort be used to treat muscular dystrophy?

Deflazacort is a new synthetic corticosteroid that is widely used in the clinical treatment of inflammatory diseases, immune-mediated diseases and specific genetic diseases. Among them, the treatment of Duchenne Muscular Dystrophy (DMD) is of great significance. DMD is an X-linked genetic disease that mainly affects the skeletal muscle development of boys, leading to gradual muscle degeneration and loss of function. Clinical studies and guidelines show that corticosteroids can delay the decline of muscle function, improve upper and lower extremity mobility, and reduce the incidence of respiratory complications.

As a relatively new glucocorticoid, deflazacort’s main advantage in DMD patients is that it has milder side effects on bone density and weight gain than traditional steroids (such as prednisone). For DMD patients aged 2 years and above, deflazacort can delay muscle fiber degeneration by regulating inflammatory responses, inhibiting immune-mediated muscle fiber damage, and improving patients' daily life functions. Its pharmacological mechanism mainly involves inhibiting the expression of inflammatory factors after binding to hormone receptors, reducing immune-mediated damage and maintaining muscle fiber stability, thereby delaying the process of muscle degeneration.

In actual clinical practice, deflazacort usually requires long-term use, and the dose needs to be individually adjusted based on weight, age, and disease progression. The doctor will comprehensively evaluate the patient's bone density, blood sugar, blood pressure and other indicators to formulate the safest and most effective treatment plan. Although deflazacort cannot cure DMD, its ability to significantly improve muscle function and delay the progression of the disease makes it one of the core drugs currently used to treat DMD. With the promotion of international guidelines and clinical practice, deflazacort has gradually become an important part of the standard treatment plan for DMD worldwide.
