The causes and remedies of cracking
a. Causes related to formulation (granulation):
Causes Remedies
Large size of granules Reduce granule size. Add fines.
Too dry granules. Moisten the granules properly and
add proper amount of binder.
Granulation too cold. Compress at room temperature.
b. Causes related to machine:
Causes Remedies
Deep concavities cause cracking Use tapered die. The use of a tapered
while removing tablets die, which essentially minimizes the
interaction of the die edge with the
expanding compact, can help to
minimize damage
3- Chipping:
Defined as the breaking of tablet edges, while the tablet leaves the press or
during subsequent handling and coating operations.
Reason: Incorrect machine settings, especially miss-set ejection take-off.
