Flowability Testing of Directly Compressible Excipients According to British Pharmacopoeia

A review of co-processed directly compressible excipients.

Direct compression is the preferred method for the preparation of tablets. The present review outlines the importance of the functionality of the directly compressible adjuvants in the formulation of tablets. The co-processing is the most widely explored method for the preparation of directly compressible adjuvants because it is cost effective and can be prepared in-house based on the functiona...

Effect of compressional force on the crystallinity of directly compressible cellulose excipients.

The effect of compressional force on the crystallinity of low crystallinity cellulose (LCPC), microcrystalline celluloses (Avicel PH-101, PH-102 and PH-302 grades) and powdered cellulose (Solka Floc BW-100) has been investigated using an X-ray diffraction method. Microcrystalline and powdered celluloses showed an increase of about 10% in their crystallinities, compared to the values for the cor...

Development of directly compressible co-processed excipients for solid dosage forms

The tablets manufactured by direct compression method using co-processed excipient showed relatively better disintegration time and in vitro drug release, with omission of number of laborious steps as compared to tablets manufactured by conventional wet granulation method. Melt granulation technique is a potential alternative for the development of directly compressible adjuvants. Lactose and m...

The Old English illustrated pharmacopoeia: British Library Cotton Vitellius CIII

Hippocrates and Galen, the translations made from Greek to those from Arabic, and using the more recent translations in preference to older ones: for example, the translation of the Royal book of 'Ali ibn al'Abbas made by Stephen of Antioch (Liber regalis) rather than the older version of Constantine the African (Pantegni). But, beyond this, he adds his personal stamp. He provides what is proba...
