ABSTRACT

Tablet manufacture is a paradox. They are solid preparations each of which contains a single dose of one or more active ingredients. The tablet is the most popular dosage form because it provides advantages for all concerned in the production and consumption of medicinal products. All tablets are made by a process of compression. Irrespective of the type of press that is used, the process of tablet compression can be divided into three stages: filling, compression, and ejection. The purpose of the mixing stage is to ensure that the powder blend and hence the resulting tablets are homogeneous in content. The fluidized bed drier is the most commonly used device for drying tablet granules. A lubricant is a substance that deforms easily when sheared between two surfaces, and hence when interposed between the tablet and the die wall, provides a readily deformable film.
