Mechanism of action

Xiaflex contains clostridial collagenase, an enzyme that cleaves collagen in pathological fibrotic cords. By enzymatically degrading the collagen matrix of Dupuytren's contracture cords, the drug weakens the tissue structure, enabling subsequent manual manipulation by a healthcare provider to straighten the affected fingers. This minimally invasive approach avoids surgical excision while achieving similar functional outcomes.
