The oral route of drug administration is the most important and most user-friendly route of administration. In recent years, Multiple Unit Pellet Systems (MUPS) tablets are widely used in solid dosage form design. MUPS is considered to provide pharmacokinetic advantages compared to monolithic dosage forms. Combination of drug substances and release profiles can be provided by formulating the MUPS tablets with different pellet qualities or combining pellets with drugs in powder or granulated form. MUPS tablet contains several hundred of coated pellets of active pharmaceutical ingredients which delivered the drug at predetermined rate and absorption to provide constant blood profile. MUPS are easily administered as disintegratable tablet which disperse into their subunits across the stomach and the small intestine, leading to predictable oral transition and constant bioavailability.
Multiple Unite Pellet Systems (MUPS) as Drug Delivery model
Multiparticulate drug delivery systems are mainly oral dosage form, consist of small discrete units that exhibit different characteristics especially in release pattern and drug bioavailability. These systems are represented by granules, pellets, microspheres, mic rocapsules, and minitablets. Pellets offer high flexibility in the design, formulation, and development of oral dosage forms such as sachet, suspension, capsule, and tablet. Multiparticulate tablets manufactured by compaction of multiple unite pellets is one of the latest and, yet, challenging technologies. Multiparticulate tablets combine the benefits of both a tablet and a pellet-filled capsule in one dosage form but their manufacturing experience many difficulties. The oral multiparticulate products consist of polymer-coated subunits or pellets, which are embedded in an inert excipients' matrix, formulated to overcome the difficulty in administering capsules and improve the physicochemical stability of suspension and offer predictable release and uniform distribution in the gastro-intestinal tract compared to the plain tablet. This review discusses the advantages and drawbacks of MUPS, the properties of an ideal MUPS, various pharmaceutical applications of MUPS, the challenges and key variables that to be considered in the tableting process for successful production of MUPS

Oral drug delivery system becomes challenging when the drug product needs to be delivered in modified release pattern in elderly patients, especially since it is difficult to swallow for them. Multiparticulates are the choice of dosage form when fast disintegration is desirable without loss of original release profile. Compressed multi-particulate system prepared by using pellets have several pharmacokinetic, pharmacodynamic, commercial and other advantages as mentioned henceforth in this review article. It includes not only different types of modified release pellets that can be compressed into Multiple Unit Pellet System (MUPS) but also factors regulating the compression behavior of pellets including properties of pellets, core material, and compressible excipients. This review also presents detailed explanation on physicochemical properties of pellets and formulation strategies of MUPS.
Accepted Manuscript Tablets of multi-unit pellet system for controlled drug delivery
The tablet of multi-unit pellet system (TMUPS), using coated pellets, for controlled release of drugs is an effective therapeutic alternative to conventional immediate-release dosage forms. The main advantages of TMUPS include a) ease of swallowing and b) divisible without compromising the drug release characteristics of the individual units. TMUPS can be prepared more economically than pellet-filled capsules because of the much higher production rate of tableting process. In spite of the superiorities of TMUPS, its adoption has been challenged by manufacturing problems, such as compromised integrity of coated pellets and poor content uniformity. Herein, we provide an updated review on research, from both scientific literatures and patents, related to the compaction of TMUPS. Factors important for the successful production of TMUPS are summarized, including model drug property, potential cushioning agents, and novel techniques to protect pellets from damage. This review is intended to facilitate the future development of manufacturable TMUPS with drug release behavior similar to that of the original coated pellets.
Multi Unit Drug Delivery System - A Brief Review of Pelletization Technique
2014
At present time pharmaceutical research and development showing its interest on drug delivery.Which enhances therapeutic action while minimising side effect. Use of multi-particulate is the gift of that research which achieve delayed or controlled release with low risk of dose dumping, flexibility of blending to attain different release pattern as well as reproducible and short gastric residence time.Pelletization is a novel approach for the formation of spherical beads or pellets from fine powder or blend in order to develop site specific drug delivery system. Different techniques of pelletization such as suspension/solution layering, extrusion and spheronisation, cryopelletization etc. can be used for the formation of multi particulate drug delivery system. In order to provide extended or delayed release formulation, thus extending the frontier of future pharmaceutical development.
Pharmaceutical Pellets: A Versatile Carrier for Oral Controlled Delivery of Drugs
Indian Journal of Pharmaceutical Education and Research, 2016
In pharmaceutical industries, pellets are multiparticulate dosage form which was formed by the agglomeration of fine powdered excipient and drugs together that leads to the formation of small free flowing spherical or semi spherical particles. This technique is called as pelletization process. Pellets are typically varied between 500-1500 µm in size for pharmaceutical applications. It is of great interest over other similar techniques due to its uniformity of dose, less susceptibility of dose dumping, less friability etc. With the advent of controlled release technology, drug loaded pellets have been widely investigated for its control release property in gastrointestinal tract. This review will provide an insight into previous studies on pelletization techniques, investigation of various pelletization techniques namely: layering, extrusion spheronization, cryopelletization, hot melt extrusion. It also gives a brief idea about the evaluation of pellets; parameters affecting pelletization, the different available marketed pellet formulation.

Pelletization Techniques for Oral Drug Delivery
Multiparticulates are discrete particles that make up a multiple unit system. Although pellets have been used in the pharmaceutical industry for more than four decades, with the advent of controlled release technology, that the full impact of the inherent advantages of pellets over single unit dosage forms have been realized, not only has focused on refining and optimizing existing pelletization techniques, but also focused on the development of novel approaches and procedures for manufacturing of pellets. The present review outlines the manufacturing and evaluation of pellets. The manufacturing techniques include layering, cryopelletization, freeze pelletization, extrusion spheronization and hot melt extrusion have been discussed. Characterization of pellets is discussed with reference to the particle size distribution, surface area, porosity, density, hardness, friability and tensile strength of pellets.

Oral multiunit pellet extended release dosage form: A review
International Current Pharmaceutical Journal, 2013
Oral drug delivery is the most preferred route for the various drug molecules among all other routes of drug delivery, because ease of administration which lead to better patient compliance. So, oral extended release drug delivery system becomes a very promising approach for those drugs that are given orally but having the shorter half-life and high dosing frequency. Recent trends indicate that multiparticulate drug delivery systems are especially suitable for achieving extended release oral formulations with low risk of dose dumping, flexibility of blending to attain different release patterns as well as reproducible and short gastric residence time. The release of drug from pellets depends on a variety of factors including the carrier used to form pellets and the amount of drug contained in them. Consequently, pellets provide tremendous opportunities for designing new controlled and extended release oral formulations, thus extending the frontier of future pharmaceutical developmen...
