Mechanism of action

Clostridial collagenase is a protease enzyme derived from Clostridium histolyticum that specifically degrades collagen types I and III, the primary structural components of fibrotic tissue. When injected directly into pathological collagen deposits, it enzymatically cleaves the collagen matrix, weakening the tissue architecture and enabling manual manipulation or passive stretching to restore mobility and function.
