Usage
This combination medication is primarily used as a topical skin protectant and antiseptic. It is prescribed for minor skin irritations, including:
- Nappy rash (diaper rash): Protects the skin and soothes irritation.
- Contact dermatitis: Soothes inflammation and itching.
- Minor burns, cuts, and abrasions: Forms a protective barrier and aids healing.
- Eczema: Provides symptomatic relief.
- Insect bites and stings: Reduces itching and inflammation.
Pharmacological Classification: Topical protectant, antiseptic, anti-inflammatory, and antipruritic agent.
Mechanism of Action: The components work synergistically: Calamine soothes and relieves itching; Cetrimide acts as an antiseptic; Dimethicone forms a moisturizing barrier; Sucralfate creates a protective layer, and Zinc Oxide acts as a protectant and mild antiseptic.
Alternate Names
Calamine-Cetrimide-Dimethicone-Sucralfate-Zinc Oxide cream/lotion. Several brand names exist (e.g., Sufrate, Norash Cream) depending on the manufacturer. International and regional variations may exist. There are no widely recognized proprietary names.
How It Works
Pharmacodynamics: The combined action of its ingredients provides a comprehensive approach to skin irritation and protection. Calamine provides a soothing effect and helps relieve itching and inflammation. Cetrimide, an antiseptic, helps kill bacteria and fungi. Dimethicone forms a protective barrier, preventing further irritation. Sucralfate creates a protective layer over irritated skin promoting healing. Zinc oxide acts as a skin protectant, antiseptic, and mild astringent, creating a barrier against moisture and irritants.
Pharmacokinetics: Primarily for topical application, systemic absorption is minimal. Pharmacokinetic parameters like absorption, distribution, metabolism, and excretion are not clinically significant in typical use cases.
Mode of Action: Calamine and Zinc oxide exert anti-inflammatory and astringent effects. Cetrimide disrupts bacterial cell membranes causing cell death. Dimethicone creates a hydrophobic barrier, moisturizing skin and reducing transepidermal water loss. Sucralfate adheres to the skin, creating a physical barrier against irritants.
