Risdiplam Uses
Risdiplam is used in the treatment of spinal muscular atrophy (SMA).
How Risdiplam works
Risdiplam works by helping the body make more protein called survival motor neuron (SMN) protein, which is needed for muscles and the nerves that control them. In spinal muscular atrophy, the body cannot produce enough of this protein, leading to muscle weakness. Risdiplam acts on a gene, and improves the way it functions so the body can produce higher, more useful levels of SMN protein. With better protein levels, the nerve cells stay healthier, muscles get better support, and the progression of muscle weakness can slow down.
