Which drug is commonly used to treat muscular dystrophy?

Corticosteroids are commonly used to treat muscular dystrophy due to their anti-inflammatory properties and ability to help preserve muscle strength and function. In conditions such as Duchenne muscular dystrophy, corticosteroids have been shown to slow muscle degeneration and improve the overall quality of life for patients. By reducing inflammation and potentially influencing muscle regeneration, corticosteroids play a critical role in managing the symptoms associated with muscular dystrophy.

Other classes of drugs mentioned are not typically used for muscular dystrophy. Antidepressants focus on managing mood disorders and do not address the underlying muscle weakness. Beta-blockers are primarily used for cardiovascular issues and do not have a role in the treatment of muscular dystrophy. Opioids, while effective for pain management, do not contribute to the treatment of muscle function or the progression of muscular dystrophy.
