Crystallization has the vital role in the pharmaceutical industry as it is started from intermediates separationprocess and the
final manufacture step as active pharmaceutical ingredients. Crystallization is a key component of almost all processes
in the manufacturing of pharmaceuticals. Whether for purification of intermediates, formation of the product, or prevention
of crystallization in amorphous products, crystallization is essential in both processing & development. Crystallization can be
natural or artificial process of formation of solid crystal sprecipitating from a solution melts or more rarely deposited directly
from a gas. Crystallization is also a chemical solid?liquid separation technique, in which mass transfer of a solute from the liquid
solution to a pure solid crystalline phase occurs. If we take an example of third generation, semi synthetic, broad-spectrum
cephalosporin Ceftriaxone sodium, which belongs to β-lactam antibiotics. This is most in demand able anti-infectious production
India and abroad. The continuous methodical studies and development of R& D have been performed to resolve the problems
faced in the industry manufacture of ceftriaxone sodium, for example the low yield of batches, less commercial batches and no
uniform of the quality so on. With the help of R & D the problem is studied and continuous lab batches taken and data evaluated.
A new process of dilution crystallization has been successfully used for industry manufacture of ceftriaxone sodium, and the
product quality, yield and size were enhanced much more than that of the old technology. In past the India has done more studies
and research on the crystal formation of ceftriaxone sodium. By evaluating the type of equipment for crystallization, solvent
quality, maintaining temperature, recovering solvent, time for reflux, effects of seeds, stirring RPM control, purification and
concentration of mother liquor the crystallization process is developed. After intensive work on the crystallization of ceftriaxone
sodium has been determined, and the product quality, yield and size are improved.
