In this review, we have discussed on various parameters affecting pelletization, different techniques of pelletization and assessment of pellets. Expert opinion It is expected that the pellatizaiton is an effective and efficient approach which can help in improvement of absorption, bioavailability, stability, etc. Pellets can offer therapeutic advantages with effordable cost. Several studies are performed to address the limitations of numerous drugs.
