FRIABILITY

A tablet’s strength has a significant impact on its marketing, transportation and dissolution. The mechanical strength of tablet or granules can be determined by its hardness and through friability test. A clear synthetic polymer drum with polished internal surfaces that is not susceptible to static buildup shouldbe used; it should have an internal diameter of 283 to 291 mm and a depth of 36 to 40 mm. The drum has a detachable side. A curving projection that runs from the center of the drum to the outside wall and has an inside radius of 75.5 to 85.5 mm tumbles the tablets with each rotation of the drum. A device that revolves at 25 ±1 rpm has the drum fixed to its horizontal axis. As a result, the tablets slide or roll during every rotation, landing on the drum wall or one another. Friability test procedure and Acceptance Criteria

COMPRESSION PROCESS IN PHARMACEUTICAL MANUFACTURING

TABLET COMPRESSION: Reducing the bulk volume of a powder by applying mechanical force so as to form a defined shape of desired weight and strength is called ‘Compression’. Tablet compression is the process of squeezing powders together and driving out the air between the particles, resulting in a compressed Tablet. WHY COMPRESSION? TABLET PRESS OR … Read more

Unit Operations during manufacture of Tablets:

Unit Operations: The manufacture of Tablets is a complex multi-stage process under which the starting materials change their physical characteristics a number of times before the final dosage form is produced. Numerous unit operations are involved in making Tablets including sifting, mixing, granulation, drying, sizing, blending, lubrication, compression and coating. DISPENSING OF RAW MATERIALS (API … Read more
