Hardness makes sure tablets can endure producing and managing stresses. Friability tests area toughness and disintegration confirms how promptly tablets stop working in fluid. Dissolution decides the rate of drug launch.
The main features of the dissolution test for the duration of early levels of progress are to characterize therapeutic efficacy, bioequivalence, and bioavailability of API. During afterwards phases of the development procedure, dissolution testing is likewise useful for good quality Manage (QC) uses.
