  • Which drugs undergo film coating for photostabilization?
  • Tablets containing light sensitive drugs (e.g., sorivudine, nifedipine, sulfisomidine, and molsidomine) undergo film coating for photostabilization . Photostability mainly depends on the thickness of coating layers and can also be affected by concentration of the opacifier .
  • Does film coating aqueous based or solvent based improve tablet formulation?
  • On the basis of the study that the film coating as solvent based or aqueous based improve the tablets formulation, Physical and chemical aspects, during process arise a various types of defects in coating, these defect reducing the effectiveness of the product.
  • Which polymers are used to improve drug stability?
  • Various water soluble and insoluble polymers, including polysaccharides, polypeptides, and vinyl polymers, are also widely used for film coating to improve drug stability . The film coating approach used to improve the stability of drugs or drug products is exemplified as follows.
  • Can film coating improve product stability of moisture-sensitive drugs?
  • Film coating of core tablets has also been attempted to improve the product stability of moisture-sensitive drugs using various water-proof coating agents including polyvinyl alcohol (PVA), Eudragit ® EPO, hydroxypropyl methyl cellulose (HPMC), hydroxyethyl cellulose (HEC), and polyvinyl alcohol-polyethylene glycol (PVA-PEG copolymer).
  • Which film forming agent is used in active film coating?
  • The API is directly mixed with the film-forming agent in active film coating, and there is no limitation in selection of the film-forming agent, including polyacrylates, polyvinyl alcohol, hypromellose, and hydroxypropyl cellulose .
  • Why are plasticizers used in film formation?
  • Film formation depends on the physicochemical properties of polymers . Plasticizers are also used to reduce the glass transition temperature (Tg) and increase flexibility to avoid cracking and subsequent peel-off of polymer films .
