Abstract

The present invention is directed to a composition for treating bacterial skin infections, along with skin rejuvenation. More particularly, the present invention relates to a pharmaceutical cream comprising a biopolymer, and an antibacterial active ingredient. It discloses a composition for treating fungal skin infections along with skin rejuvenation containing a) a biopolymer in the form of chitosan, b) an active pharmaceutical ingredient (API) composition in the form of framycetin sulphate used in treating bacterial skin infections, c) a cream base containing primary and secondary emulsifiers, waxy materials, co-solvents, acids, preservatives, buffering agents, anti oxidants, chelating agents, and humectants and d) water. The active ingredients, namely chitosan, and an anti bacterial agent in the form of framycetin sulphate, are incorporated in cream base for use in treating bacterial skin infections with allergy & itching, & wounds on human skin involving contacting human skin with the above identified composition.

Description

technical field [0001] The present invention relates to compositions for the treatment of bacterial skin infections and skin regeneration. More specifically, the present invention relates to a medicinal cream comprising a biopolymer and an antibacterial active ingredient, neomycin B sulfate. Background technique [0002] Skin diseases are broadly classified by the bacterial form or fungus from which they arise. Antifungal or antibacterial compositions are commonly used as lotions, creams or ointments. Also, in some cases it is difficult to determine whether the skin condition is due to a bacterial factor or a fungus. [0003] One approach to treating skin diseases is eradication by trial and error. The antibacterial or antifungal composition is administered alternately to monitor response and modify treatment. The main disadvantage of this method is that multiple sessions per day are required during the treatment period. This is inconvenient and uneconomical for most pe...
