Tablet manufacturing

FRIABILITY

by

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.

UNDERSTANDING PRE-REQUISITES FOR TECHNOLOGY TRANSFER

by

Technology transfer is both integral and critical to drug discovery and development process for new medicinal drug products. A major decision focuses on that point where the idea or process is advanced from a research-oriented program to targeted toward commercialization. Generally, the cost of product development rises dramatically during the pilot scale-up and initial production … Read more

COATING PROCESS IN PHARMACEUTICAL MANUFACTURING:

by

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

GRANULATION PROCESS IN PHARMACEUTICAL MANUFACTURING:

by

Granulation is required to improve the flow of powder mixtures and mechanical properties of Tablet. Granulation is the act or process in which primary powder particles are made to adhere to form larger, multiparticle entities called granules. It is the process of collecting particles together by creating bonds between them. Bonds are formed by compression … Read more

Unit Operations during manufacture of Tablets:

by

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
