1.DILUENT  Diluents are fillers to make bulk of the tablet.
 Ex: Lactose , starch , dextrose etc.
2.BINDER &
ADHESIVE
Added either dry or wet-form to form
granules/compacts.
Ex: acacia , starch , CMC, PVP.

Ex: starch , cellulose , clays .
4. LUBRICANTS
Prevent adhesion tablet materials to the surface of
dyes & punces.
Ex: stearic acid ,Talc,surfactants.

coating technics.
Suitable for large scale production.
ADVANTAGES

12. Difficult to swallow in case of children and

Some drug resist compression into dense compacts
,owing to amorphous nature ,low density
characters.
Drugs with poor wetting ,slow dissolution
properties.
Bitter tasting drugs,drugs within an objectionable
odour or drugs that are sensitive to oxygen may
require encapsulation or coating.
