1. Introduction to Paracetamol Tablets IP 500 mg – Batch Manufacturing Record (BMR):
Paracetamol Tablets IP 500 mg are widely used pharmaceutical formulations with analgesic and antipyretic properties, commonly administered for the relief of mild to moderate pain and reduction of fever. Each uncoated tablet contains 500 mg of Paracetamol IP as the active pharmaceutical ingredient. The Batch Manufacturing Record (BMR) for Paracetamol Tablets IP 500 mg provides comprehensive documentation of manufacturing activities, ensuring product quality, consistency, traceability, and compliance with Good Manufacturing Practices (GMP). The manufacturing process involves raw material dispensing, sifting, binder preparation, dry mixing, wet granulation, fluid bed drying, milling, blending, lubrication, tablet compression, and packaging. Each operation is performed according to approved manufacturing instructions and documented by authorized personnel. Critical process parameters, including granulation conditions, moisture content, blending time, tablet weight, hardness, thickness, friability, and disintegration time, are monitored to maintain established quality standards. The BMR specifies a theoretical batch yield of 800,000 tablets, with an average tablet weight of 600 mg and a total theoretical batch weight of 480 kg. Quality Assurance and Quality Control departments oversee in-process checks, documentation verification, material reconciliation, and final product release.

The flow diagram illustrates the systematic manufacturing process of Paracetamol Tablets IP 500 mg using the wet granulation method. The process begins with dispensing and weighing approved raw materials, including Paracetamol IP and pharmaceutical excipients, according to the Batch Manufacturing Record (BMR). The materials undergo sifting to eliminate foreign particles and ensure uniform particle size. Starch paste is prepared as a binding agent, followed by dry mixing and wet granulation using a Rapid Mixer Granulator (RMG).
The wet granules are dried in a Fluid Bed Dryer (FBD) to achieve the specified moisture content. Subsequently, dried granules undergo milling, sizing, blending, and lubrication to improve flow properties and compressibility. The lubricated granules are compressed into tablets using a tablet compression machine. Critical quality parameters, including weight variation, hardness, thickness, friability, and disintegration, are monitored. Finally, tablets undergo blister packaging, inspection, reconciliation, and Quality Assurance verification to ensure GMP compliance and product quality.
3. Critical Process Parameters (CPP) and Critical Quality Attributes (CQA) of Paracetamol Tablets IP 500 mg:
Critical Process Parameters (CPPs) and Critical Quality Attributes (CQAs) are essential for ensuring consistent quality, safety, and efficacy during the manufacturing of Paracetamol Tablets IP 500 mg. CPPs include dispensing accuracy, sifting mesh size, binder preparation, granulation time, impeller speed, drying temperature, milling screen size, blending duration, lubrication time, and compression settings. These parameters require monitoring and control to maintain manufacturing consistency.
Critical Quality Attributes include raw material identity, purity, granule moisture content, flow properties, blend uniformity, tablet weight variation, hardness, thickness, friability, disintegration time, assay, and finished product appearance. According to the Batch Manufacturing Record (BMR), the standard tablet weight is 600 mg, granule moisture content is maintained between 1.8% and 2.4%, friability is not more than 1%, and disintegration time is not more than 15 minutes.
