What is Anacaulase?[edit | edit source]

  • Anacaulase (Nexobrid) is a mixture of proteolytic enzymes extracted from the stems of pineapple plants (Ananas comosus [L.] Merr.) that has been sterile filtered and lyophilized.
  • The drug substance, anacaulase-bcdb, is composed mainly of the proteins: stem bromelain, ananain, jacalin-like lectin, bromelain inhibitors, and phytocystatin inhibitor; and saccharides, as both free monosaccharides and the N-linked glycan of stem bromelain, and small molecule metabolites.

What are the uses of this medicine?[edit | edit source]

Anacaulase (Nexobrid) is used for eschar removal in adults with deep partial thickness (DPT) and/or full thickness (FT) thermal burns.

What special precautions should I follow?[edit | edit source]

  • Serious hypersensitivity reactions, including anaphylaxis, have been reported with postmarketing use of Nexobrid. If a hypersensitivity reaction occurs, remove Nexobrid and initiate appropriate therapy.
  • Eschar removal with Nexobrid and treatment-related burn wound procedures are painful and require adequate analgesia and/or anesthesia. At least 15 minutes prior to Nexobrid application ensure adequate pain control measures are in place to address Nexobrid-related pain.
  • Nexobrid is not recommended for treatment of burn wounds where medical devices (e.g., implants, pacemakers, shunts) or vital structures (e.g., large vessels) could become exposed during eschar removal. Protect any open wounds (e.g., laceration, abraded skin and escharotomy incision) with skin protectant ointments or ointment gauze to prevent possible exposure to Nexobrid.
  • A reduction of platelet aggregation and plasma fibrinogen levels and a moderate increase in partial thromboplastin and prothrombin times have been reported in the literature as possible effects following oral administration of bromelain, a component of Nexobrid. Avoid use of Nexobrid in patients with uncontrolled disorders of coagulation. Patients should be monitored for possible signs of coagulation abnormalities and signs of bleeding.
