Tablet Coating: Uses, Techniques and Types

Introduction:

Tablet Coating is a thin coating of film for covering the surface of the tablet using a high-quality machine. It is one of the oldest techniques for coating tablets in the drug industry. However, it is still valid and a running method for tablet coating. 

The tablet/film/sugar coating process helps in masking the colour, smell and taste of the drug. The machinery is widely used in the pharmaceutical and drug industry. It is also used in the food processing industry as well. 

What is the tablet coating technique/process?

The process of tablet coating includes applying a substantially dry coating to the surface of the drug for protecting it. It technically involves the application of a sugar or polymeric coat on the surface of the tablet. It benefits the tablet by increasing its durability and quality. Apart from the physical and chemical protection, it also aids with the protection of the drug inside the stomach by safeguarding its release process. 

The different types of tablet coating techniques include:

  1. Standard Coating
  2. Perforated Coating
  3. Fluidised Bed or Air Suspension
