Usage
This combination medication is a topical antiseptic and antibiotic primarily prescribed for the management and prevention of infections in second and third-degree burn wounds. It also aids in promoting wound healing.
Alternate Names
Burnosaf, Sufrate SSD, Slvrgen.
How It Works
Pharmacodynamics:
-
Chlorhexidine Gluconate: A cationic antiseptic that disrupts bacterial cell membranes, causing leakage of cellular contents and ultimately bacterial death. It exhibits a broad spectrum of activity against gram-positive and gram-negative bacteria, fungi, and some viruses.
-
Silver Sulfadiazine: A sulfonamide antibiotic that exerts its bacteriostatic effect by inhibiting bacterial folic acid synthesis. It interferes with the synthesis of dihydropteroic acid, necessary for bacterial DNA and RNA synthesis. Silver ions also contribute to its antibacterial activity by binding to bacterial DNA and cell membranes.
-
Sucralfate: Although primarily known for its use in treating ulcers, when applied topically, sucralfate forms a protective barrier over the wound. This physical barrier helps to protect the wound from further injury, reduces pain, and creates a favorable environment for healing.
Pharmacokinetics:
Topical application minimizes systemic absorption. However, some absorption may occur with application to large burn areas, especially in young children or patients with impaired skin barrier function. Sulfadiazine can be absorbed systemically and is primarily excreted by the kidneys. Chlorhexidine has low systemic absorption when applied topically.
Dosage
Standard Dosage
Adults: Apply a thin layer to the cleaned and dried affected area once or twice daily.
Children: Apply a thin layer to the cleaned and dried affected area once or twice daily for children older than 2 months. The use of this medication is not recommended in premature babies or infants 2 months of age and younger. Pediatric dosage may be adjusted based on the child’s weight and the extent of the burn. Monitor for potential systemic absorption, particularly in young children with large burns.
Special Cases:
- Elderly Patients: No specific dosage adjustments are generally needed; however, close monitoring of renal function is recommended, especially in patients with pre-existing renal impairment.
- Patients with Renal Impairment: Close monitoring is advised, and dosage adjustments of the sulfadiazine component may be necessary.
- Patients with Hepatic Dysfunction: Caution should be used. Monitor liver function tests.
- Patients with Comorbid Conditions: Use with caution in patients with G6PD deficiency due to the risk of hemolytic reactions.
Clinical Use Cases
Dosing in these scenarios generally follows standard dosage recommendations, but close monitoring of patient and wound site is essential.
- Intubation: Not applicable for this topical medication.
- Surgical Procedures: Can be used post-operatively to prevent infection in burn wounds.
- Mechanical Ventilation: Not applicable for this topical medication.
- Intensive Care Unit (ICU) Use: Standard dosage can be used for managing burns in ICU patients.
- Emergency Situations: Can be applied in emergency settings to manage burns immediately after injury.
Dosage Adjustments
Adjustments may be necessary based on patient-specific factors such as the extent and severity of the burn, the patient’s age, and the presence of renal or hepatic impairment.

FAQs (Frequently Asked Questions)
Q1: What is the recommended dosage for Chlorhexidine Gluconate + Silver Sulfadiazine + Sucralfate?
A: Apply a thin layer to the cleaned and dried affected area once or twice daily for adults and children older than 2 months.
Q2: Can this medication be used in pregnant or breastfeeding women?
A: The safety in pregnancy and breastfeeding has not been fully established. Consult a physician before use. It is generally contraindicated near term pregnancy, labor, and delivery. Use with caution during breastfeeding.
Q3: What are the common side effects?
A: Common side effects include itching, burning, redness, dryness, and rash at the application site.
Q4: What are the serious side effects I should watch for?
A: Although rare, serious side effects can include Stevens-Johnson syndrome, leukopenia, exfoliative dermatitis, and toxic epidermal necrolysis. Any signs of these should be reported and the medication stopped.
Q5: Are there any drug interactions I should be aware of?
A: Yes. Avoid using with other topical antiseptics. Anionic compounds in some soaps may inactivate chlorhexidine. Concomitant use with other sulfa drugs may increase the risk of adverse reactions. Debriding agents like collagenase may interact with the medication.

A: Chlorhexidine disrupts bacterial cell membranes, silver sulfadiazine inhibits bacterial growth, and sucralfate forms a protective barrier to promote healing.
Q7: Can this cream be used on all types of wounds?
A: While it can be used on various wounds and ulcers, it is primarily indicated for the management of second and third-degree burn wounds.
Q8: What should I do if a dose is missed?
