Definitions

  • the subject matter described herein generally relates to a process for the preparation of Bi/Multi- layer film, Multi-layered film produced thereof and also apparatus for producing such Multi-layer film.
  • the subject matter described herein particularly relates to process for the preparation of Multi-layer film for oral, transmucosal, transdermal or topical applications in humans or animals, Multi-layered films produced thereof and also apparatus for producing such films.
  • Thin film is a dosage form that is used for delivering various active pharmaceutical agents, nutraceuticals and dietary additives. When administered by oral route, these films have many advantages over existing oral solid dosage forms like, tablets, orally disintegrating tablets, capsules, etc. When compared to tablets or capsules thin films do not require swallowing and hence are an ideal dosage form for pediatric, geriatric, mentally challenged and dysphagic patients. Specifically, when compared to orally disintegrating tablets, thin films are quite flexible and are not friable so can withstand stress during transportation and handling.
  • Liquid formulations are generally preferred for patient populations having difficulty in swallowing but, the same have issues of storage, transport and handling. Instances of dose non- uniformity are also quite high with liquid formulations. Thin films being, unit solid dosage form that require much less volume for storage and is free from spillage but is fast dissolving. These attributes of thin films obviate such limitations of liquid formulations.
  • Thin films also offer a very convenient way of drug administration through buccal, sublingual and transdermal routes as these have higher surface area for faster drug permeation and can be made mucoadhesive.
  • one of the layers of the Multilayer film may be a backing layer, which is required for adherence to mucosal or skin surfaces or to maintain unidirectional permeation of active ingredients through the mucosal surfaces.
  • Example 1 also describes the method of preparation of two layered film, wherein the backing layer was casted, cured and dried. After two coating and drying iterations, the mucoadhesive polymeric layer was casted onto the backing layer, cured and dried.
  • This method may also faces issues relating to a wet layer being added over a dried first layer. If the solvent system used in both the layers is different then the casting of second layer over the first layer does not result in the film with smooth surfaces because of the interfacial tension between two layers. In case of same solvent systems in both the layers, there are chances of migration of API from mucoadhesive layer to backing layer resulting in inconsistent rate of permeation through transmucosal membranes.
  • EP 1079813B 1 reports casting of one layer over the other while the first layer is completely wet or partially dried.
  • This disclosure mentions the use of hydrophilic solvents in both layers.
  • a wet film is casted on already dried film layer because of thin nature of base layer, it gets dissolved to some extent. Due to this process mixing between two layers take place and chemical interaction between incompatible actives or active-excipients may be observed. Additionally, this process is not suitable for incorporating thermolabile actives into base layer as the base layer is exposed to heat two times, firstly during drying of base layer and secondly during drying of subsequent layers.
  • This disclosure also mentions preparation of bilayer films using lamination of individual layers on to each other. During the process of lamination one layer is dried while the other layer is partially wet. In this method there will be need of additional drying steps after lamination that again may not be suitable for thermolabile actives and presence of extra moisture may also cause chemical degradation.

  • step (a) placing each layer obtained in step (a) over one another;
  • At least one layer of two adjacent layers of the multi-layer film comprises one or more of a binding excipient having a melting point in the range of 30°C to 100°C, preferably, 35°C to 70°C as an integral component of said layer and said binding excipient binds the layers together on application of heat and pressure.
