NOVELTY - Zolpidem tartrate film agent comprises (wt.%) zolpidem tartrate (1-40), high molecular weight film forming material (e.g. hydroxypropyl methyl cellulose (HPMC), hydroxy propyl cellulose (HPC), polyvinyl alcohol (PVA), polyvinylpyrrolidone (PVP), and/or sodium alginate) (40-98), plasticizer (e.g. polyethylene glycol (PEG)) (0-20), titanium dioxide (0-3), and flavoring agent (1-30), where total weight is 100 wt.%.    USE - Zolpidem tartrate film agent.    ADVANTAGE - The zolpidem tartrate film agent can quickly dissolve and has good stability. It can be directly stuck to the surface of the mucosa and can be quickly absorbed; can prevent first-pass effect of liver; has high bioavailability, quick effect, and good compliance; and is convenient to use. After the film agent is administered, it can be directly adsorbed without being dispersed, so that the raw medicine can be kept to continuously release medicine with accurate amount. There is no flying dust during the production of the film agent. The preparation of film agent solves the problem of labor protection and environmental pollution.    DETAILED DESCRIPTION - Zolpidem tartrate film agent comprises (wt.%) zolpidem tartrate (1-40), high molecular weight film forming material (40-98), plasticizer (0-20), titanium dioxide (0-3), and flavoring agent (1-30), where total weight is 100 wt.%. The high molecular weight film forming material comprises HPMC, HPC, PVA, PVP, sodium alginate, polyoxyethylene (PEO), Bletilla mucilage, corn starch, and/or carrageenan. The plasticizer comprises PEG, glycerol, and/or Tween 80 (RTM: polyoxyethylene (20) sorbitan monooleate). An INDEPENDENT CLAIM is included for preparation of zolpidem tartrate film agent comprising adding zolpidem tartrate hydrochloric acid solution or powdered hydrochloric acid and plasticizer to water solution containing 10-35 wt.% high molecular weight film forming material and dispersing; adding titanium dioxide and flavoring agent, dispersing, if there is air bubble in solution, standing for 1 night, and removing bubble in vacuum; and extending the solution on stainless steel belt, glass plate, or plastic film, drying, embossing by an embossing roller, cutting into certain size, removing from the stainless steel belt, glass plate, or plastic film, sealing, and packing.
