“TECHNICAL AND PATENT PERSPECTIVE ON FILM FORMING TOPICAL SPRAYS”

Abstract

Film-forming systems were a viable option for topical and transdermal medication administration in the present study. Medication administered via the skin serves two purposes: topical treatment of skin disorders and transdermal drug absorption into the circulation. Apart from the ease of self-administration, the topical route provides a broad and diverse surface and functions as a substitute for oral and hypodermic injection drug delivery routes. Existing dosage forms, such as creams, patches, and ointments, have several drawbacks. In addition to being unsightly, patches can be painful to put on curved surfaces, create discomfort while peeling off, and most often cause skin irritation because of their occlusive qualities, which block sweat ducts and prevent perspiration from evaporating from the skin surface. This review encompasses the mechanism of polymers, such as ethyl cellulose and Eudragit types, plasticizers, and penetration enhancers utilized in film formation. Overall, polymeric film-forming sprays exhibit substantial potential for the convenient administration of antibiotics and antiseptics to treat bacterial, fungal, and viral skin infections. The application of topical medication is thought to result in both local and systemic effects. The physicochemical characteristics of the medication and patient adherence determine how well the topical treatment works. Poor permeability and poor adherence to the skin are some of the disadvantages of conventional pharmaceutical formulations for topical and dermatological administration. The development of medication delivery technologies intended for topical administration to the skin includes the use of topical film-forming systems.
