Process Analytical Technology (PAT) is a framework initiated by the FDA to design, analyze, and control pharmaceutical manufacturing processes through timely measurements of critical quality attributes. Implementing PAT ensures consistent product quality and enhances manufacturing efficiency.

Core Components of PAT
o Real-Time Monitoring: Utilizes sensors and analytical tools to assess critical parameters during production.
o Data Analysis: Employs statistical tools to interpret data, facilitating informed decision-making.
o Process Control: Adjusts manufacturing conditions in real-time to maintain product quality .

Coating is essential in pharmaceutical manufacturing, enhancing tablet aesthetics, stability, and controlled drug release. Technological advancements have refined coating processes, ensuring better product performance and patient compliance.

Types of Coatings
o Sugar Coating: Traditional method involving multiple layers, enhancing taste and appearance but increasing tablet size.
o Film Coating: Applies a thin polymer layer, offering protection and controlled release without significantly altering tablet dimensions.
o Functional Coatings: Includes enteric and sustained-release coatings, targeting drug release in specific gastrointestinal regions .

Granulation is a pivotal process in pharmaceutical manufacturing, transforming fine powders into granules to enhance flowability, compressibility, and uniformity. Over the years, granulation techniques have evolved, incorporating advanced technologies to meet the stringent requirements of modern drug production.
Traditional Granulation Methods

Wet Granulation:
Involves adding a liquid binder to the powder mixture, forming a wet mass that’s subsequently dried and sieved. This method improves the cohesiveness of powders but may not be suitable for moisture-sensitive drugs.
