Treatment options

Evidence-based approaches to managing this condition.

First-line treatments

1

Asfotase alfa enzyme replacement

Recombinant tissue-nonspecific alkaline phosphatase replacement therapy to address the underlying enzyme deficiency. This targeted therapy helps improve bone mineralization and reduce skeletal manifestations.

Additional treatment options

Calcium and vitamin D supplementation

Adequate calcium intake combined with vitamin D supplementation to support bone health. Dietary modifications may be necessary based on individual nutritional needs and absorption capacity.
