Currently, a wide variety of wound dressings of varying composition and effects is used to treat wounds. These include also film dressings where one of the promising materials for its preparation is sodium carboxymethylcellulose (NaCMC) as a material of natural origin with excellent film-forming properties. Its application is particularly in the field of absorbent dressings, films for wounds from this material are not used in practice yet. Hidden potential offers also dexpanthenol, a substance widely used in dermatological practice. Therefore, the aim of this research was to prepare films from textile NaCMC with dexpanthenol by the solvent evaporation method and their subsequent physicochemical evaluation. The presence of microfibrillar fibers of partially substituted carboxymethylcellulose together with HCMC has ensured optimal parameters for wound application such as pH, swelling and mechanical properties. The films showed satisfactory mass content uniformity and those with dexpanthenol also drug content uniformity.
