Embodiment 1

[0025] Example 1, 0.3 parts of tacrolimus, 150 parts of stearic acid, 150 parts of castor oil, 100 parts of liquid paraffin, 20 parts of triethanolamine, 60 parts of glycerin, 420 parts of distilled water, 40 parts of lauryl methyl sulfoxide , 40 parts of oleic acid, 80 parts of polyvinyl alcohol-124, 30 parts of peppermint oil (all by weight)

[0026] Preparation method: Mix stearic acid, castor oil, and liquid paraffin, and melt on a water bath at 80°C. Separately take triethanolamine, glycerin and distilled water, mix well, heat to the same temperature, slowly add oil phase, stir while adding until emulsification is complete, cool for later use. Separately take lauryl methyl sulfoxide, oleic acid, polyvinyl alcohol-124 and peppermint oil, add finely ground tacrolimus, and stir well. The obtained product is added into the ointment base prepared above while stirring, and the product is obtained.

Abstract

The invention provides a tacrolimus ointment composition and a preparation method of the tacrolimus ointment composition. The tacrolimus ointment composition provided by the invention has enhanced permeability and reduction of skin irritation, and can be used for the treatment of atopic dermatitis.

Description

technical field [0001] The invention relates to an ointment composition containing tacrolimus. The novel ointment compositions of the present invention are useful as skin topical delivery systems for the treatment of atopic dermatitis. technical background [0002] Atopic dermatitis (AD, also known as atopic eczema) is a chronic, relapsing, inflammatory skin disease characterized by severe itching. related to abnormal immune function. Due to the lack of effective treatment methods, it has a great impact on the quality of life of patients, and its incidence is increasing, so it has become a research hotspot in recent years. In the past 40 years, topical corticosteroids have become the main treatment for AD, but these drugs have obvious limitations in the treatment of AD. Long-term use can easily lead to adverse reactions such as skin atrophy and thinning, telangiectasia, etc., so it is limited to short-term treatment, and Hormone preparations cannot be used on the face and...
