Authored by leading experts from academia, users and manufacturers, this book provides an authoritative account of the science and technology involved in multiparticulate drug delivery systems which offer superior clinical and technical advantages over many other specialized approaches in drug delivery. The book will cover market trends, potential benefits and formulation challenges for various types of multiparticulate systems. Drug solubility, dose, chemistry and therapeutic indications as well as excipient suitability coupled with manufacturing methods will be fully covered. Key approaches for taste-masking, delayed release and extended release of multiparticulates systems are of significant interest, especially their in-vivo and in-vitro performance. In addition, the principles of scale-up, QbD, and regulatory aspects of common materials used in this technology will be explained, as well as recent advances in materials and equipment enabling robust, flexible and cost-effective manufacture. Case studies illustrating best practices will also make the book a valuable resource to pharmaceutical scientists in industry and academia.

Controlled Release in Oral Drug Delivery provides focus on specific topics, complementing other books in the initial CRS series. Each chapter sets the context for the inventions described and describe the latitude that the inventions allow. In order to provide some similar look to each chapter, the coverage includes the historical overview, candidate drugs, factors influencing design and development, formulation and manufacturing and delivery system design. This volume was written along three main sections: the relevant anatomy and physiology, a discussion on candidates for oral drug delivery and the major three groups of controlled release systems: diffusion control (swelling and inert matrices); environmental control (pH sensitive coatings, time control, enzymatic control, pressure control) and finally lipidic systems.

Multiparticulates or pellets are more popular as sustained released dosage forms. These multiparticulates offer flexibility in dosage form design by filling them into capsule, compression into a tablet either conventional or fast dissolving or into sachets that can be administered along with food. They are also helpful in minimizing the effect of food on absorption as they flow freely in the gastro-intestinal tract irrespective of presence or absence of food and the opening or closing nature of pyloric sphincter. This book therefore provides an approach of pellets for enhancing dissolution rate of Telmisartan using different carriers like PVP, PEG 4000, PEG 6000, Mannitol, Sodium Lauryl Sulphate, Magnesium Oxide and Sodium bicarbonate along with various manufacturing methods, advantages, various technologies that employ pellets. Factorial design was used for optimizing the concentration of carrier and size of the pellets. Use of Magnesium oxide and Sodium bicarbonate satisfied the dissolution requirements. Size of non-pareil seeds and carrier ratio were optimized using a 2x2 factorial design.

The present study is aimed to develop floating, pulsatile, multiparticulate drug delivery system intended for chronopharmacotherapy in arthritis. Cross-linked beads were prepared by using low methoxylated pectin, sodium alginate, low methoxylated pectin + Sodium alginate and low methoxylated pectin + deacetylated gellan by acid- base reaction during ionotropic gelation. Beads were dried in oven at 500 degree Cenntigrate for 4hr. Aceclofenac was used as a model drug for encapsulation. Drug loaded multiparticulates were subjected to various characterization and evaluation parameters like entrapment efficiency, buoyancy study, surface topography.
