Potency of Topical Corticosteroids in Combination Preparations

Phase 4

• Conditions: Skin Toxicity

• Registration Number: NCT03606954
• Lead Sponsor: Ben-Gurion University of the Negev

Brief Summary

Several combination topical drugs are available on the market. The potency of corticosteroids depends on a particular molecular structure and the skin penetration properties. Besides molecular structure, a penetration of a corticosteroid molecule correlates with physical properties of the vehicle which depend on physical properties of the vehicle constituents.

Vasoconstriction assay is considered as the gold standard for testing potency of topical corticosteroids.

Detailed Description

Primary outcome: Change in Vasoconstriction index following application of topical corticosteroids that are incorporated with or without an antibiotic and/or antifungal drugs in healthy volunteers.
