Direct Compressible Excipients, which can be used universally with any of the APIs, can lead to a revolution in tablet manufacturing techniques by way of low cost and efficient tablet rnanufacturing. These economical advantages will be beneficial for both manufacturing and consumer, we can also go for certain synthetic but inert materials, and by using them we can produce tablets using ingredients than otherwise could not possibly be compressed to a tablet.
Direct Compressible Excipients, which can be used universally with any of the APIs, can lead to a revolution in tablet manufacturing techniques by way of low cost and efficient tablet rnanufacturing. These economical advantages will be beneficial for both manufacturing and consumer, we can also go for certain synthetic but inert materials, and by using them we can produce tablets using ingredients than otherwise could not possibly be compressed to a tablet. From all this, the direct compression technique can be taken as the best alternative for conventional tablet manufacturing and is best suited to industrial expectations too.
Nowadays, we have a long list of materials which can help in the direct compression of certain materials, which are otherwise not easy to be directly compressed, and this is done by imparting certain characteristics. To the materials to be compressed and by the use of certain new technologies, all together, these excipients can lead to easy manufacturing of tablet dosage forms for the APIs, which are not compatible with water, and thus make the use of the wet granulation technique difficult.
