5 Tips about sustained and controlled release You Can Use Today
The decision to work with a sustained release or extended release formulation is dependent upon the nature of the situation getting handled and the specified outcomes. Right here’s why you may select one about the other:➢ Dry Granulation Approach: In this process, the API and excipients are compacted to variety slugs or ribbons, which happen to be then milled into granules. These granules are compressed into tablets. ➢ Soaked Granulation Process: In this technique, the API and excipients are blended, and a liquid binder is extra to sort a wet mass.
