How are granules prepared?
Granules are prepared by two methods – Dry or wet granulation. Dry granulation includes dry mixing, slug-de-slug and roller compaction processes. Wet granulation includes aqueous granulation and non-aqueous granulation. Dry granulation can be achieved through roller compaction or slugging.
