There are three main methods of tablet production, namely, direct compression, dry granulation and wet granulation.
Direct compression: Whenever applicable, D.C. is the most preferred method because of its simplicity. D.C. method composes only of three steps which are weighing, mixing and compression.
> Low labor input.
> Dry process (useful for water sensitive drugs).
> Fewest processing steps.
> Less time consuming.
> Less cost than other methods.
> Reduced dust formation and Lower health risks at the workplace
> Easy dosing, Good flowability and reduced agglomeration during transport and storage, which avoid additional processing costs.
> Good tabletting properties, which help to reduce the quantity & cost of binding agents
> High compressibility at low compression forces for harder tabletsümaking “carriers” unnecessary, thus helping to save costs.
