Problems solved by technology

However, fusidic acid precipitates are difficult to process into cream form, the first reason is its coarse and uneven particle size, and the second reason is that the recovery of fusidic acid from wet cake involves drying and further processing, which causing fusidic acid to be destroyed by exposure to oxygen
[0013] The stability of the API in fusidic acid cream is unreliable due to the thermolabile nature of fusidic acid

Abstract

The present invention discloses a skin cream comprising an antifungal agent, a steroid and an antibacterial agent in the form of fusidic acid formed in situ with sodium fusidate as a starting material, wherein fusidic acid Sodium acid is converted to fusidic acid in the absence of oxygen. The cream of the present invention has higher shelf-life stability and finer API particle size than conventional creams containing fusidic acid. The cream of the present invention comprises as API fusidic acid and steroids which have been formed in situ from sodium fusidate in a cream base comprising acids, co-solvents, emulsifiers and waxy materials and Water, preferably purified water.

Description

technical field [0001] The present invention relates to primary and secondary bacterial skin infections and inflammations, and in particular to single-dose treatment with steroid and antifungal creams also comprising an antibacterial agent in the form of fusidic acid, wherein The acid has been prepared using sodium fusidate as the starting active pharmaceutical ingredient (API). Background technique [0002] Steroids are known to be used to reduce inflammation, irritation and itching caused by skin disorders. Steroid use is also known to compromise a patient's immune system and expose the patient to the risk of bacterial and fungal infections. Single-dose treatments comprising steroids, antifungals and antibacterials are known. [0003] Multiple bolus treatments, local and systemic, are currently used to treat the above skin inflammations. Compositions for the treatment of local and systemic inflammation typically use a combination of corticosteroids as an essential compo...
