DEVELOPMENT OF LOW-DOSE SOLID ORAL TABLETS USING DIRECT COMPRESSION

DEVELOPMENT OF LOW-DOSE SOLID ORAL TABLETS USING DIRECT COMPRESSION [Pg.159]

Direct compression is a simpler alternative tablet manufacturing method. With direct compression, tablets are compressed directly from a powder mixture of an API and appropriate excipients. Like granulation methods, this approach is also based on the required flow, compressibility, and compactibility of a formulation. Direct compression offers both time and economic advantages by eliminating intermediate granulating and drying steps. [Pg.159]

The first direct compression excipient, spray-dried lactose, was introduced in the early 1960s as a filler specifically designed for direct compression processes. Over many years, more direct compression API and excipients, especially diluents and binders, were developed. Since these are now commercially available, design of direct compression formulations is readily possible. However, despite the simplicity of the direct compression process, the pharmaceutical industry still produces most tablets by wet granulation methods.1 [Pg.159]

Lubrication is an important unit operation in manufacturing solid oral dosage forms, particularly when using a direct compression platform. Pharmaceutical lubricants can have a significant impact on product performance (e.g., disintegration and dissolution) as well as manufacturability. Lubrication is one of the most critical aspects of a tablet formulation. A lubricant is intended to reduce the friction between the tablet surface and die wall during and after compaction to enable easy ejection of the tablet. In low-dose dmg product development, three issues are associated with lubricating a direct compression formulation ... [Pg.168]
