Pharmaceutical Tablet Film Coatings | PharmaCentral
The different steps involved in a typical tablet film coating, as it is carried out presently, can be split into several stages: Preparation of the coating dispersion This step is required in order to effectively transform coating components into a medium that can be efficiently applied onto the coating substrates.
Film coating | SEPPIC
Seppic develops effective and easy-to-use film coating agents for medications and dietary supplements, thanks to its expertise in film coating, and in selecting compositions based on a tablet’s type and desired functionality. The tablet coating process The coating process results in the formation of a thin layer of polymer around the tablet.
Polymers used for Fast Disintegrating Oral Films: A Review
It has film-forming properties and can be used as a substitute for gelatin or other film-forming polymers in certain foods. A white to off-white tasteless, odourless powder that forms a viscous non-hygroscopic solution when dissolved in water at 5-10%. Pullulan starts to decompose at 250°C and chars at 280°C.
Thin-film drug delivery
Combination of microcrystalline cellulose and maltodextrin has been used to formulate Oral Strips of piroxicam made by hot melt extrusion technique. Pullulan has been the most widely used film former (used in Listerine PocketPak, Benadryl, etc.) Plasticizers [ edit] Plasticizer is a vital ingredient of the OS formulation.

Sorbitol Special is an effective plasticizer for soft gel formulations which makes soft shells more robust. These grades reduce drying time, driving productivity and also enhance the gloss of capsules for a premium appearance. Ingredient (s): Sorbitan, Sorbitol Dosage Form: Softgels Category: Film Formers & Plasticizers
- Which film forming formulation is best for tablet coating?
- 4. Executive summary In conclusion, tablet coating films made of HPMC 5cPs with the addition of PEG at 1.5% and SLS at 0.3% and films made of HPMC 5cPs with PG at 1% and Tween-80 at 0.3% could be considered as an elegant film forming formulation for solving different coating problems generally faced in an industrial scale.
- Which plasticizers are used in aqueous based film coating formulation?
- Proper optimization for the aqueous based film coating formulation was undertaken primarily employing plasticizers like polyethylene glycol (PEG) 400 and propylene glycol (PG).
- How do plasticizers affect film properties?
- The type and concentration of plasticizers can affect the film properties, as revealed by several investigations ( Mortada, 1990, Siepmann et al., 2005, James, 1997 ). The plasticizing efficiency is measured by the lowering of the incidence of coat defects.
- What are plasticizers used for?
- Plasticizers are relatively low molecular weight materials which are added to film-coating formulations to modify the physical properties of polymers.
- What should a film-coated tablet look like?
- Schematic representation of the film-coating process Film-coated tablets should have even coverage with uniform colour coverage across the surface of each dosage unit within a batch, and from batch to batch. Film-coated tablets must be free from defects which affect functionality and stability of the finished product.
- How does a tablet coating work?
- The coating formulation contains a polymer solubilized in a suitable solvent together with other additives like plasticizers and pigments. This solution is sprayed onto a rotating or fluidized tablet bed. The drying conditions cause removal of the solvent, leaving a thin deposit of coating material around each tablet core.
