One knows that a tablet is the most common form of medication for the administering of drugs in a dry state. Its preparation constitutes an important part of modern “Pharmaceutical Technology”. The method of tablet making or tabletting is defined as a process of pressure of powdered medicine.
It is generally observed that some tablets are made easier from certain drugs than from other ones. For example, sodium chloride is used without the addition of auxiliary substances. But for lactose the addition of such substances is necessary to overcome certain difficulties. It is interesting that in the process of tabletting some materials are continuously binding and sticking in the special machine. Sticking takes place when there is too much moisture in the granules because of insufficient drying, etc.
The application of different pressure during tabletting plays a very great role. It is important that tablets which are being dissolved slowly by saliva in the mouth are more strongly compressed than other ones using for common internal administration. Another important effect of higher pressures is an increase of friction which causes the use of greater amount of lubricating and gliding substances, such as natural starch. The use of starch as an auxiliary component in tablet making is generally recognized. It was stated that starches possessed very good gliding properties and didn’t show any lubricating action.
