It refers to wrapping a thin layer of polymer coating around the core of the tablet to form a film, which is called film coating. Film coating materials require film-forming materials, plasticizers, solvents and other materials. Materials that form films are further divided into stomach-soluble film-forming materials and enteric film-forming materials.
Features:
1. Easy to operate, saving materials and labor, and low cost.
2. The tablet weight only increases by 2%-4%, saving packaging materials.
3. It has less adverse effects on disintegration and drug dissolution than sugar coating.
4. The logo pressed on the tablet core is clearly visible.
Extended information:
The functions of film-coated tablets are to prevent moisture, light, isolate air, increase stability, and mask the bad taste of drugs. Ordinary film-coated tablets should generally be taken as a whole tablet, and can be broken into pieces when necessary.
Disadvantages
1. High production costs and low profits;
2. Quality gives way to cost, and the concept of cost is vague.
