Industrial Pharmacy-I is the introductory part of industrial pharmacy, a branch of pharmaceutics focusing on the large-scale production and quality assurance of medicines. This book (or course) introduces students to the basic principles, materials, and processes used in pharmaceutical manufacturing. It bridges the gap between laboratory formulation and commercial production, ensuring that drug products are safe, effective, and of consistent quality. The book begins with the history and scope of industrial pharmacy, emphasizing regulatory requirements and Good Manufacturing Practices (GMP). It covers the classification of dosage forms with special focus on solid dosage forms such as tablets, capsules, and powders, since they represent the majority of marketed drugs. Students learn about raw material handling, preformulation studies, and factors affecting large-scale production. A major part of Industrial Pharmacy deals with manufacturing processes granulation (dry and wet), compression, coating, and encapsulation. Each process is explained with flowcharts, equipment details, in-process controls, and defect rectification. The book also highlights the importance of quality control tests such as dissolution, disintegration, friability, and weight variation to meet pharmacopoeia standards. Finally, it emphasizes documentation, validation, and regulatory compliance to ensure batch-to-batch consistency and patient safety. Industrial Pharmacy-I thus provides pharmacy students with a foundation to understand the industrial environment, production technologies, and the quality systems necessary for successful pharmaceutical manufacturing.
