What is coated tablet?

Coated tablets are pharmaceutical products that have a thin layer of coating on their outer surface. The coating serves as a protective layer for the active ingredient, preventing it from being released until it reaches the target site in the body. The coating also provides a barrier that protects the active ingredient from degradation due to environmental factors such as light, heat, and moisture.

The coating of the tablet may be made of different materials, such as sugar, polymer resins, or cellulose derivatives, depending on the specific application of the product. They may be colored to help in the identification of the product, improve appearance, or make it easier to swallow.

Coated tablets have many advantages over uncoated tablets, including:

1. Improved stability: The coating provides a protective layer, preventing the active ingredient from being exposed to environmental factors that may cause degradation.

2. Better patient compliance: Coated tablets are usually smoother and easier to swallow, which can improve patient compliance.

3. Controlled release: The coating can be designed to control the release of the active ingredient, allowing for sustained release over a specific period.

Overall, coated tablets are a useful pharmaceutical product that offers many benefits both to the manufacturer and the patient.
