The dissolution specification is defined by the amount (Q) of active substance that dissolves within a designated time frame, represented as a percentage of the content indicated on the product label. According to the Indian Pharmacopoeia, the dissolution specification is articulated in terms of the amount (D) of active substance that dissolves in a specified … Read more
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

UNDERSTANDING COATING: Coating can be defined as a physical deposition of a layer on Tablet surface for the purpose of masking the Taste, odour, appearance, physical / chemical protection or to control the drug release. Coating process is the application of coating composition to a moving bed of Tablets in a coating pan by concurrent … Read more
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
BLENDING PROCESS: Blending of solid particles refers to mixing of solids with the aim of attaining a uniform composition throughout the mix. In powder blending two or more dissimilar particulate solids are blended to give a random mix. Objective of blending is to form a homogeneous final product from two or more dissimilar raw materials. … Read more
MILLING PROCESS: Milling process is also called as ‘screening’ and ‘sizing’ process. Milling is employed between RMG and Blending to crush the larger particles from granulation into uniform small particles which meets the process requirement. Milling isperformed to remove lumps, improve flow, reduce segregation and to control the particle size. Milling is performed by using … Read more
