Background: There is no single-component excipient that fulfills all the requisite performance to allow an active pharmaceutical ingredient to be formulated into a specific dosage form. Co-processing is a novel concept that incorporates a combination of two or more excipients, that is advantageous and cannot be achieved using a physical admixture.
Objective: This review provides an overview of co-processed excipients, recent patents granted and filed in this field and the commercial patented technology platforms based on these excipients.
Methods: Various online patent databases were used for collecting the information on recent patents and patented co-processed excipient technologies. The recent patents such as single-step coprocessing by dry coating, novel co-processed excipients for oily drugs and novel silica-coated compositions have been discussed.
Results: Co-processed excipients are evolving as a current and future trend of excipient technology in pharmaceutical manufacturing, which is evident by the increasing number of patents based on these excipients. Among various techniques, the maximum number of patents is based on the spray drying technique.
Conclusion: In this work, the authors have focussed on recent patents and commercial technologies on co-processed excipient. A better understanding of this will help researchers and pharmaceutical industries to select the appropriate platform, or to develop new innovative co-processed excipients with improved tableting characteristics.

Kollidon® SR is one of the recent versatile coprocessed excipients in the formulation of modified-release dosage forms. It is prepared by co-spray drying aqueous dispersions of polyvinylacetate and polyvinylpyrrolidone. This article gives a critical review of the physicochemical attributes and technological properties of Kollidon® SR.

: Improving the production rates of modern tablet presses places ever greater demands on the performance of excipients. Although co-processing has emerged as a promising solution, there is still a lack of directly compressible excipients for modified-release formulations. The aim of the present study was to address this issue by investigating the potential of novel co-processed excipients for the manufacture of modified-release tablets containing ibuprofen.

Microcrystalline cellulose (MCC) has been isolated from numerous sources through acid hydrolysis of mercerized cellulose. Due to the fibrous shape, its poor flow ability and lower compactibility, MCC is often co-processed with other excipients to improve its functional properties. Musa MCC was isolated from the pseudostem of Musa balbisiana and silicified with 2 % silicon dioxide (SMCC) through homogenization followed by filtration and oven drying.

Background/objectives: Hydroxypropyl methylcellulose (HPMC) is one of the most commonly used hydrophilic polymers in formulations of matrix tablets for controlled release applications. However, HPMC attracts moisture and poses issues with drug stability in formulations containing moisture-sensitive drugs.
Methods: Herein, the moisture sorption behavior of excipients and drug stability using aspirin as the model drug in matrix tablets were evaluated, using HPMC and the newly developed mannitol-coated HPMC, under accelerated stability conditions (40 °C, 75% relative humidity) with open and closed dishes.

Poor water solubility is an important challenge in the development of oral patient-friendly solid dosage forms. This study aimed to prepare orodispersible tablets with solid dispersions of a poorly water-soluble drug fenofibrate and a co-processed excipient consisting of mesoporous silica and isomalt. This co-processed excipient, developed in a previous study, exhibited improved flow and compression properties compared to pure silica while maintaining a high specific surface area for drug adsorption.
