Direct tableting has been renewed as a preferable process by simply mixing and compressing powder to save time and cost in comparison with granule tableting. Direct compression tableting as a technique has been successfully applied to numerous drugs on the industrial scale, although the success of any procedure, and resulting mechanical properties of tablets, is strongly affected by the quality...

The paper evaluates and compares the compressibility and compactibility of directly compressible tableting materials for the preparation of hydrophilic gel matrix tablets containing tramadol hydrochloride and the coprocessed dry binders Prosolv® SMCC 90 and Disintequik™ MCC 25. The selected types of hypromellose are Methocel™ Premium K4M and Methocel™ Premium K100M in 30 and 50 % concentrations...

The tableting behavior of drugs can be affected by changes in the crystal habit. Different crystal habits of the common analgesic drugs ibuprofen and acetaminophen were prepared. Their tableting behavior was characterized. In the case of ibuprofen, a plate-shaped crystal was compared with the common needle-shaped form. In the case of acetaminophen, plate-shaped and prismatic crystals of two dif...

The suitability of the new isomalt grade galenIQ™ 801 for dry granulation and following tableting is evaluated in this study. Isomalt alone, as well as a blend of equal parts with dibasic calcium phosphate, is roll compacted and tableted. Particle size distribution and flowability of the granules and friability and disintegration time of the tablets are determined. Tensile strength of tab...

objective(s) ibuprofen is a problematic drug in tableting, and dissolution due to its poor solubility, hydrophobicity, and tendency to stick to surface. because of the bad compaction behavior ibuprofen has to be granulated usually before tableting. however, it would be more satisfactory to obtain directly during the crystallization step crystalline particles that can be directly compressed and ...

The demands on the functionality of excipients are increasing day by because emergence high-speed tableting machines and use direct compression methods for tableting. Direct compressible is preferred method preparation tablet. Excipient play an important role in formulating a dosage form. these ingredient which along with active pharmaceutical make up forms. act as protective agent, bulking age...

Direct tableting is simpler and more cost-effective from the point of view of good manufacturing practice (GMP) than wet granulation or dry compacting. Moreover, the use of dry plant extracts in the process of direct tableting, omitting granulation, decreases the possibility of biological activity loss of active substances. Thus, pharmaceutical industry uses this particular process more and mor...

Objective(s) Ibuprofen is a problematic drug in tableting, and dissolution due to its poor solubility, hydrophobicity, and tendency to stick to surface. Because of the bad compaction behavior ibuprofen has to be granulated usually before tableting. However, it would be more satisfactory to obtain directly during the crystallization step crystalline particles that can be directly compressed and...

The present work deals with the spherical crystallization process by Spherical agglomeration method applied to Zaltoprofen, a novel NSAID drug. The object of present study was to prepare and characterize the spherical agglomeration of water insoluble non-steroidal anti-inflammatory drug. Zaltoprofen spherical agglomerates prepared with poly ethylene glycol, which is hydrophilic polymer by using...

The microcrystalline cellulose is an important ingredient in pharmaceutical, food, cosmetic and other industries. In this study, the microcrystalline cellulose, obtained from the stalk of Sorghum caudatum was evaluated for its physical and tableting characteristics with a view to assessing its usefulness in pharmaceutical tableting. The microcrystalline cellulose, obtained from the stalk of Sor...
