Collagenase

INDICATIONS AND USAGE Collagenase Santyl ◊ Ointment is indicated for debriding chronic dermal ulcers 2, 3, 4, 5, 6, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 and severely burned areas. 3, 4, 5, 7, 16, 19, 20, 21

DOSAGE AND ADMINISTRATION Collagenase Santyl ◊ Ointment should be applied once daily (or more frequently if the dressing becomes soiled, as from incontinence). When clinically indicated, crosshatching thick eschar with a #10 blade allows Collagenase Santyl ◊ Ointment more surface contact with necrotic debris. It is also desirable to remove, with forceps and scissors, as much loosened detritus as can be done readily. Use Collagenase Santyl ◊ Ointment in the following manner: 1 - Prior to application the wound should be cleansed of debris and digested material by gently rubbing with a gauze pad saturated with normal saline solution, or with the desired cleansing agent compatible with Collagenase Santyl ◊ Ointment (See PRECAUTIONS ), followed by a normal saline solution rinse. 2 - Whenever infection is present, it is desirable to use an appropriate topical antibiotic powder. The antibiotic should be applied to the wound prior to the application of Collagenase Santyl ◊ Ointment. Should the infection not respond, therapy with Collagenase Santyl ◊ Ointment should be discontinued until remission of the infection. 3 - Collagenase Santyl ◊ Ointment may be applied directly to the wound or to a sterile gauze pad which is then applied to the wound and properly secured. 4 - Use of Collagenase Santyl ◊ Ointment should be terminated when debridement of necrotic tissue is complete and granulation tissue is well established.

ADVERSE REACTIONS No allergic sensitivity or toxic reactions have been noted in clinical use when used as directed. However, one case of systemic manifestations of hypersensitivity to collagenase in a patient treated for more than one year with a combination of collagenase and cortisone has been reported.
