Question

Purpose of Seal coating step of Sugar coating is

• A. Gives smooth surface to the tablet
• B. Enhances weight of the tablet for coating
• C. Gives sweet taste to the Tablet
• D. Prevent moisture penetration into the tablet

Answer 1

The Correct Option is D

The purpose of the seal coating step in the sugar coating process of tablets is primarily to prevent moisture penetration into the tablet. Let's examine this in more detail:

1. Understanding the Role of Seal Coating:
   • Seal coating is the initial step in the sugar coating process.
   • Its primary function is to protect the tablet core from moisture by creating a barrier.
   • This step is crucial because moisture can deteriorate the active ingredients or alter the mechanical properties of the tablet.
2. Eliminating Incorrect Options:
   • Gives smooth surface to the tablet: While a smooth surface is achieved in later stages (e.g., smoothing and polishing steps), it is not the primary function of seal coating.
   • Enhances weight of the tablet for coating: Increasing weight is a result of the overall sugar coating process, not specifically the sealing step.
   • Gives sweet taste to the Tablet: The sweet taste is imparted during the actual sugar coating phase, not during seal coating.
3. Conclusion:
   • Based on the analysis, the correct answer is that the purpose of seal coating is to prevent moisture penetration into the tablet.

Thus, the seal coating step is a protective measure to ensure the integrity and stability of the tablet before proceeding to other stages of sugar coating.
