Embedding of dithranol in lipid crystals

Area of Science:

• Dermatology
• Pharmaceutics
• Materials Science

Background:

• Psoriasis is a chronic inflammatory skin condition.
• Dithranol is an effective topical treatment for psoriasis.
• Conventional Dithranol formulations can cause skin staining and are difficult to remove.

Purpose of the Study:

• To develop a new cream base for Dithranol formulations.
• To improve the stability and usability of Dithranol creams.
• To create an antipsoriatic cream that is nonstaining and easily washable.

Main Methods:

• Formulation of a cream base using lipid crystals of C12 and C14 monoglycerides.
• Incorporation of Dithranol into the developed cream base.
• Evaluation of cream properties including lipid melting point, Dithranol stability, washability, and staining potential.

Main Results:

• The cream base utilizes lipid crystals (C12 and C14 monoglycerides) that are solid at room temperature and melt at skin temperature.
• The formulated Dithranol cream demonstrated good stability of the active ingredient.
• The cream exhibited practical nonstaining properties and was easy to wash off the skin.

Conclusions:

• A novel lipid crystal cream base offers a promising approach for formulating Dithranol antipsoriatic treatments.
• This formulation enhances patient compliance by addressing issues of staining and washability.
• The developed cream provides a stable and user-friendly delivery system for Dithranol.
