The glucocorticoid medication vamorolone can offer the same benefits as traditional glucocorticoid medications used to manage Duchenne muscular dystrophy (DMD) but with fewer side effects, according to a recent review published in the Journal of Pharmacy Technology.
With DMD, muscles get weaker over time. The standard treatment is a class of corticosteroids called glucocorticoids — like prednisone, dexamethasone and deflazacort — which can help preserve movement but often come with long-term side effects like lower immunity to infections, weight gain, slowed growth, delayed puberty and weaker bones.
Based on the findings of five studies involving 370 patients, boys taking vamorolone demonstrated similar or better improvements in mobility compared to those taking traditional glucocorticoids. Vamorolone significantly improved key everyday movements affected by DMD, as shown by faster times for standing up from lying down, walking or running short distances and climbing stairs.
Compared to traditional glucocorticoids, vamorolone appeared safer. It helped preserve growth, supported bone health and did not lead to excessive weight gain. Bone health markers — tests which indicate how well bones are forming and maintaining strength — were significantly better in the vamorolone group.
“Vamorolone emerges as a superior contender to glucocorticoids in DMD management, enhancing motor function while sparing patients the growth and bone health pitfalls of traditional therapy,” the researchers said. “Our findings illuminate its potential to reshape DMD care, urging robust trials to pave the way for widespread clinical adoption.”

What makes vamorolone different is how it works. Like traditional steroids, it calms harmful inflammation, but it avoids activating the body in ways that usually lead to side effects.
The review also highlights how vamorolone may have a heart-protective effect. This is something worth studying further since heart problems are a major risk for people with DMD.
While the early results are encouraging, the researchers stress that larger and longer-term studies are still needed — especially to understand its full impact on heart health and quality of life over time.
