This book contains complete information about formulation and evaluation of omeprazol pellets (delayed release). Firstly it contains various methods of pellets formation along with its evaluation followed by drug profile (omeprazol). The drug profile contains its evaluation using various parameter like cars index, solubility, melting point, solubility, dissolution etc, which is utilized for its pre- formulation and evaluation. Finally a stable formulation is chosen for the various formulation made and is used for omeprazol pellet formation (delayed release).
