Why are drugs film coated?
Pharmaceutical film coating is considered a key part in the production of solid pharmaceutical dosage forms since it gives superior organoleptic properties products. In addition, it can improve the physical and chemical stability of dosage forms, and modify the release characteristics of the drug.
What mean film coated?
Definition of ‘film-coating’ Film-coating is a process in which a tablet, capsule, or pellet is covered by a thin layer of film to protect it or make it easier to swallow. Applying a thin coating to tablets is called film-coating. The outer layer applied in film-coating makes tablets easier to swallow.
Do film coated tablets dissolve?
An enteric coating stabilizes tablets. An enteric coating allows tablets to survive intact as they pass through the acidic stomach. They then dissolve in the less acidic small intestine to be absorbed.
What is used in film coating?
The most widely used polymers in non-functional film coating are cellulose derivatives such as hypromellose. Plasticizers, used to improve the flexibility of the film formed and prevent it from cracking or breaking. They work by weakening the attraction between the polymer molecules to make the film more malleable.
How does film coating work?
Film coating involves the deposition of a thin layer of film-forming polymeric onto a product substrate. The process can be carried out using conventional panning equipment but nowadays more sophisticated equipment is used to achieve efficient drying, high degree of automation and coating time.
Does film-coated mean slow release?
They may also be used to delay or augment the delivery and uptake of medications or delay release and uptake until the medication passes through the stomach. These types of film coatings are known as functional film coatings.
Are film-coated tablets vegetarian?
The following preparations are unsuitable for both vegans and vegetarians as they include gelatin as an excipient: Accrete D3 Film-Coated Tablets. Adcal D3 Chewable Tablets.
Are coated tablets better?
A coated tablet generally goes down easier and with less aftertaste. The coating on tablets can do more than just mask the taste; some pills are coated with a substance that protects them from the gastric acid produced in the stomach so they will not be broken down until they reach the small intestine.
Is it okay to chew film coated tablets?
Sugar or film coating – surrounds the tablet normally to make it taste better or easier to swallow. Crushing these types of tablets may make them to taste very unpleasant. Enteric coating – tablets with an enteric coating should never be crushed.
What is the difference between film-coated and uncoated tablets?
Tablets can be either coated with a sugar or film coating, or uncoated. Uncoated tablets are rougher, may be more difficult to swallow, and often leave a bad taste in the mouth when swallowed. A coated tablet generally goes down easier and with less aftertaste.
Can you cut film coated tablets in half?
Pills that are coated to protect your stomach, such as enteric-coated aspirin and ibuprofen, shouldn’t be split, either. Those with a hard coating and capsules of any kind are best swallowed whole because they can easily crumble, leak, or crack into pieces.
Are film-coated tablets slow release?
Tablets and capsules may have special coatings for example ‘sugar coated’, ‘film coated’ or ‘enteric coated ‘ or they may be designed to modify the rate that the drug is released into the body….Oral medication that should NOT be crushed or opened.

Are film coated tablets safe?
Film or sugar-coated medicines Disruption of the film or sugar coating on a drug may result in rapid degradation of the active ingredient and may also cause skin irritation in patients or carers.
Are film coated tablets easier to swallow?
Dr Ali Rajabi-Siahboomi, VP and Chief Scientific Officer at Colorcon, said: “Compared with other coating formulations, the superior slip provided by this coating, once wet, significantly reduces the probability of sticking in the throat or esophagus during the swallowing process.
How can coating improve a surface?
But there are three things that coatings can do for the surfaces themselves. The first is improving the appearance of the old surface. That dull surface can be turned into something illuminating. The second is protecting the surface.
What are the objectives of coating surfaces?
Coating is a covering that can be applied to the surface of an object, normally called as substrate. The purpose of application of coating is the value enhancement of the substrate by improving its appearance, corrosion resistant property, wear resistance, etc.
Are film-coated tablets safe?
Are film-coated tablets easier to swallow?
What are the advantages of film coating?
Film coating owes its success for these reasons: 1. Results is minimal weight increase (typically 2%–3% of tablet core weight), unless there is a need to achieve a modified-release effect. 2. Reduces processing times. 3. Increases process efficiency and output. 4. Exhibits formulation flexibility.
What are the disadvantages of film coating tablets?
The major disadvantage of film coating tablets is that not all drugs and excipients are suitable for coating. The film-coated tablets are intended for oral routes of administration, hence it is difficult to swallow, particularly for children, sick, and unconscious patients.
What is the difference between sugar coating and film coating?
Film coating, unlike sugar coating (which is typically only applicable to the coating of tablets), exhibits greater flexibility in enabling a broad range of products (e.g., tablets, powders, granules, nonpareils, and capsules) to be coated.
What are the common ingredients used in film coating?
Common ingredients used in many film-coating formulations are: (1) polymer, (2) plasticizer, (3) colorants, and (4) solvent/vehicle. When designing coating formulations, there are several important issues to consider.
