CNP analogues are used to treat achondroplasia, a genetic condition that leads to slowed bone growth. These medications work by mimicking C-type natriuretic peptide (CNP), which helps to regulate bone growth and development. CNP analogues are typically available in injectable forms. An example of a CNP analogue is vosoritide (Voxzogo). This medication helps to promote bone growth in children who have achondroplasia with open growth plates, potentially improving their height and overall growth patterns.
