As a means of providing a broad overview of these validation criteria, the following checklist/guideline as in Table 1, is provided for tablets and dry-filled capsules for inclusion in an in-depth validation program.

Chandra Sekhara Rao Baru2, M. association of two or more conventional excipients has enabled the design of new high performance direct compression excipients • PanExcea GR is an unique natural polymer enabling development of gastroretentive dosage forms • Since these new excipients performance is only based on the unique physical association and not a chemical change effectiveness of pharmaceutical dosage forms is termed pharmaceutics. Five different semisolid as well as two marketed preparations containing 1% diclofenac sodium were used. Studies about the effect of formulation excipients on the rheology of semisolids have contributed significantly toward their characterization.
