TABLET GRANULATION: CURRENT SCENARIO AND RECENT ADVANCES
Granulation is a size enlargement process, in fine or coarse particles converted into physically stronger and larger agglomerates having good flow property, better compression characteristics and uniformity, prevent segregation of the blend components, improve content uniformity, and eliminate excessive amounts of fine particles. Size of granules has a size range of 0.2 to 4.0 mm, depending on their subsequent use. Size of the granules depends on the quantity and feeding rate of granulating liquid. The selection of process to prepare granules requires thorough knowledge of physicochemical properties of the drug, excipients, required flow and release properties, to name a few. At current scenario available technologies includes, spray drying, roller compaction, high shear mixing, and fluid bed granulation etc. The objective of present work is to focus on the commonly used and novel granulation technologies like such as pneumatic dry granulation, steam granulation, moisture-activated dry granulation, thermal adhesion granulation, freeze granulation, and foamed binder or foam granulation.
Peer Review History:
Received 13 October 2017; Revised 25 October; Accepted 30 October, Available online 15 November 2017
UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.
