Geriatric Use Safety and efficacy in geriatric patients not established. 1 Common Adverse Effects Hypersensitivity reactions (i.e., rash, pruritus, erythema), joint inflammation, hematoma, arthralgia, headache, elevated thrombin-antithrombin levels, increased blood LDH. 1 Interactions for Factor XIII (Human) No formal drug interaction studies to date. 28 Factor XIII (Human) Pharmacokinetics Absorption Duration IV dose results in increased plasma factor XIII activity levels for approximately 28 days. 1 Plasma Concentrations Mean increase (from baseline) in plasma factor XIII activity levels after third dose (steady state) given every 28 days: 83% (range: 48 114%). 1 Elimination Half-life 5 12 days (mean: 6.6 days). 1 7 8 9 Special Populations Patients> <16 years: Possible shorter half-life and faster clearance than in adults. 1 Stability Storage Parenteral Powder for Injection 2 8°C; avoid freezing. 1 Store in original carton and protect from light. 1 Stable for 24 months at 2 8°C, up to the expiration date on carton and vial label. 1 May store at room temperature ( 25°C) for up to 6 months. 1 Do not use beyond the expiration date on carton and vial labels or beyond the period of room temperature storage, whichever comes first. 1 Do not return product to refrigerator after storage at room temperature. 1 Reconstituted solutions: Use within 4 hours after reconstitution. 1 Do not refrigerate or freeze. 1 Actions Preparation of blood coagulation factor XIII derived from pooled human plasma. 1 Congenital factor XIII deficiency is a rare but serious bleeding disorder manifested by a lifelong bleeding tendency that typically includes umbilical bleeding during the neonatal period, delayed soft tissue bruising, mucosal bleeding, poor wound healing, recurrent miscarriage, and intracranial hemorrhage. 7 9 10 13 14 16 20 23 24 27 34 Factor XIII circulates in plasma as a heterotetrameric glycoprotein consisting of 2 A-subunits and 2 B-subunits. 1 8 Enzymatic activity resides in the A-subunit; B-subunits function as carrier molecules for the A-subunits. 1 6 7 8 9 10 Factor XIII is a proenzyme that is activated in the presence of calcium by thrombin cleavage of the A-subunit to become activated factor XIII (factor XIIIa). 1 2 7 Factor XIIIa promotes cross-linking of fibrin and other proteins, resulting in a fibrin clot that is more elastic and resistant to fibrinolysis. 1 2 4 6 8 10 Factor XIIIa also cross-links α 2 -plasmin inhibitor to the α-chain of fibrin, resulting in protection of the fibrin clot from degradation by plasmin. 1 6 8 Advice to Patients Possible risk of transmission of infectious agents (e.g., viruses, and theoretically, the CJD agent). 1 Importance of reporting signs and symptoms of hypersensitivity reactions (e.g., urticaria, rash, tightness of the chest, wheezing, hypotension, anaphylaxis) experienced during or after injection of factor XIII (human). 1 Importance of informing patients of the signs and symptoms of immunogenicity (e.g., breakthrough bleeding). 1 Importance of informing patients of signs and symptoms of thrombosis (e.g., swelling of limb or abdomen and/or pain; chest pain; shortness of breath; loss of sensation or motor power; altered consciousness, vision, or speech). 1 Importance of women informing clinician if they are or plan to become pregnant or plan to breast-feed. 1 Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs, as well as any concomitant illnesses. 1 Importance of informing patients of other important precautionary information. 1 (See Cautions.)
