Dosing & Uses

AdultPediatric

Dosage Forms & Strengths

ointment

• 250 units/g

Dermal Ulcers

Apply qDay directly to wound or to sterile gauze pad, which is then applied to wound and properly secured; apply more frequently if dressing becomes soiled; terminate use of collagenase ointment when debridement of necrotic tissue is completed and granulation tissue well established

Administration

When clinically indicated, crosshatching thick eschar with a #10 blade allows ointment more surface contact with necrotic debris

Remove as much loosened detritus as can be done readily with forceps & scissors

Clean wound of debris & digested material by gently rubbing with a gauze pad saturated with NS (or other desired cleansing agent compatible with Santyl), follow with a NS rinse

If an antibiotic powder is used in case of infection, it should be applied prior to the application of Santyl.

If infection remains, discontinue Santyl until remission of infection

May be applied directly to the wound or to a sterile gauze pad which is then applied to the wound & properly secured

Terminate treatment when debridement of necrotic tissue is complete & granulation tissue is well established

Safety & efficacy not established

Warnings

Contraindications

Hypersensitivity

Cautions

Efficacy will be adversely affected by detergents, denaturants, extreme pH & certain heavy metal ions

May cause slight transient erythema in surrounding tissues

Monitor patients for the possibility of systemic bacterial infections; debriding enzymes may increase risk of bacteremia

For external use only; avoid contact with eyes

Pregnancy & Lactation

Pregnancy Category: C

Lactation: Excretion in milk unknown

Pregnancy Categories

A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

NA: Information not available.

Pharmacology

Mechanism of Action

Collagen-degrading enzyme; has high specificity for native and denatured collagen; digests collagen in necrotic tissue but not in healthy tissue; does not act on fibrin, fat, keratin or muscle
