What is A Film-coated Tablet?
This is the most extensively used tablet coating technique in the pharmaceutical industry. It personifies the tablet with different dyes and helps to stabilize the chemical compound. The unpleasant smell and taste of the pill are also masked. The film coating technique includes placing film solutions on tablets through a sprayer. This procedure is done once with a polymer, plasticizer, solvent, and dye solution. The pills are sprayed and quickly dried in a rotating tablet pan. After drying, a thin coating of polymer is created around a tablet. The tablet can sometimes keep its color; however, this can be adjusted if the solution is mixed with various dyes. There are now numerous varieties of tablet coating machines on the market. The following are the three main categories. Standard Pan Perforated Pan Fluidized Bed Processor Film Coating Process A polymer is dissolved in a solvent as well as other materials such as plasticizers, dyes, and pigments and sprayed into the tablet coater. You must put the tablets periodically into the coating pan to conduct the film coating. Measure the distance between the spray nozzle and tablet bed precisely and appropriate adjustments for even layering over the bed. The coating solution may normally atomize to very thin droplets. As the coating pan spins with the tablets, the sprayer will disperse the coating solution on the bed. Most of these devices include a multi-sprayer system. Droplets of the solvent hit the tablet and form a coating before the vapor is removed by hot air. This happens in a single-stage procedure, which retains a 2-3% rise in pill weight. The tablets are then dried to remove the solvent, resulting in a thin coating on each tablet known as a film.
Difference between film coating and enteric coating tablet?
Film coat is only coating that prevents the bitter taste while taking the medicinea nd protects the tablet from microbial growth. and color change. Enteric coat means (Enteric=Small intestine) this enteric coated tablet dissolved in only in small intestine. That means this type of coating prevents the drug release in other parts of the body. It will reacts with only small intestine fluids and get dissolved in 10mg concept. like 100mg tablet: 10mg>20mg>30mg>.......100mg complete dissolve.
Why are enteric coated tablets not crushed?
Because this would make the enteric coating coating useless and may upset the users stomach. An enteric coated tablet has a material that allows the tablet to pass through the stomach to the small intestine before the medication is released reducing the chance of stomach problems. Hope this helps. ~J

What are the advantages and disadvantages of film coating?
Film coating is less time consuming than compression coating as less time is needed to dry the coat. As the coating is thin, its presence will not affect the tablet's weight that much. This method can also be used to create sustained release formulations. However, film coating is quite expensive due to the high cost of the coating material. The quality of the film also has to be monitored to ensure that they are continuous and uniformly thick.
What is compression coating?
Compression coating involves compacting a granule around an already formed cored with compression equipment. Incompatible drugs can hence be combined together in one tablet. Sustained release drugs can also be produced. It is now rarely used today in the manufacturing industry as film coating is being used instead.

Can 1000 mg depakote tablet be cut in half?

Hydraulic pressure on tablet compression machine but in result gain hardness on tablet how the pressure is converted into hardness unit?
In the tablet compression machine main principle is compressing the upper & lower puch in a die hole . the hydraulic pressure plays a key role if we increase the hydra. pressue more compressing force on tablet then it becomes more hard.
