Crystallization has the vital role in the pharmaceutical industry as it is started from intermediates separation process and the final manufacture step as active pharmaceutical ingredients (APIs).
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 and development.

Crystallization can be natural or artificial process of formation of solid crystalsprecipitating from a solutionmelts or more rarely deposited directly from a gas.

ABSTRACT:
The purpose of the research work was to prepare and evaluate the microspheres of metoclopramide hydrochloride as a model drug by solvent evaporation method with carbopol and HPMC polymers in various proportions. A total of six formulations were prepared i.e. F1, F2, F3, F4, F5 and F6. The microspheres were evaluated for micromeritic properties, particle size, % yield, Drug content and Drug release. The size or average diameter of prepared microspheres were recognized and characterized by scanning electron microscopic methods. Microspheres were found discrete, spherical and free flowing. They ranged in particle size from 45.6- 52.2 μm. Metoclopramide hydrochloride release from these microspheres was slowed, extended and depended on the type of polymer used. The formulation F2 and F5 showed consistent drug release for up to 12 h time period. Among all the formulations, F2 contains carbopol 934 and F5 containing HPMC showed the reproducible results with best release profile and good surface morphology. Release data were analyzed based on Highuchi kinetics and Korsmeyer/Peppa’s equation and all the selected formulations showed good fit to Peppa’s equation. The work has demonstrated that among all the formulations of microspheres, particularly those of formulation F2 are promising candidates for the sustained release of metoclopramide hydrochloride in the gastrointestinal tract.

At Roche, 80,000 people across 150 countries are pushing back the frontiers of healthcare. Working together, we’ve become one of the world’s leading research-focused healthcare groups. Our success is built on innovation, curiosity and diversity, and on seeing each other’s differences as an advantage. To innovate healthcare, Roche has ambitious plans to keep learning and growing – and is seeking people who have the same goals for themselves.

Abstract:
Main source of sugar has long been cane sugar with beet sugar contributing a very less percentage. But these sugars alongwith sweetening qualities have been found to contribute calories, which can lead to various chronic diseases. Stevia rebaudiana is one such medicinal plant which have made possible to offer consumers the sweet taste without calories. Stevia alongwith sweetner offers anti-bacterial, anti-fungal, anti-inflammatory, anti-viral, anti-yeast, cardiotonic, diuretic and hypoglycaemic properties. Hence there is need to study this medicinal plant to promote this natural sweetener and create product awareness. Its genetic diversity study provides better knowledge of the herb and hence its production and so that it can be used more and more by the pharmaceutical industries to serve the mankind.
