Abstract
Additive manufacturing (AM) is widely used to fabricate 3D printed objects from Computer-aided Design (CAD) prepared using the SolidWorks CAD modelling software. Different printing techniques are used to fabricate desired 3D objects; among all these techniques, it is widely accepted that SLS is one of the most effective methods of 3D printing for fabricating drug-loaded solid oral dosage forms (SODFs) in bulk quantities using the single-step process. Different SODFs, such as pills, miniprintlets, dual miniprintlets, and tablets, were fabricated with different sizes and shapes. In this study, for the first time, we introduce SLS-mediated hollow capsular shells (HCSs) with the help of the SLS 3D printing technique. This work aimed to explore the sinterability and feasibility of sketching HCSs using the SLS-mediated sintering technique with different marketed sizes of capsules ranging from 000 to 5. Here, we have utilized Kolliphor P 188 (KP 188) and Kollidon SR (KSR) in a 1:1 ratio as a matrix-forming agent and 1% charcoal as a laser absorption-enhancing material. In accordance with the CAD models, we have fabricated the gradient conventional different sizes of HCSs ranging from 000 to 5 using the constant printing parameters and composition. Fabricated all biobased HCSs were subjected to the assessment of mechanistic and physicochemical parameters using varied analytical tools. In the current study, tartrazine dye is used to assess the release pattern from HCSs, which resulted in the modified release pattern. The adapted approach will be the futuristic approach to replace animal-based gelatin capsules with pharmaceutical-grade polymer-based HCSs with a modified release with optimum mechanical strength.

Abstract
Light-based three-dimensional (3D) printing has been under use extensively to fabricate complex geometrical constructs which find a vast application in the fields of drug delivery and tissue engineering fields due to its ability to recapitulate the intricate biological architecture and thus provides avenues to achieve previously unachievable biomedical devices. The inherent problem associated with light-based 3D printing (from a biomedical perspective) is that of light scattering causing inaccurate and defective prints which results in erroneous drug loading in 3D printed dosage forms and can also render the environment of the polymers toxic for the biological cells and tissues. In this regard, an innovative additive comprising of a nature-derived drug-cum-photoabsorber (curcumin) entrapped in naturally derived protein (bovine serum albumin) is envisaged to act as a photoabsorbing system that can improve the printing quality of 3D printed drug delivery formulations (macroporous pills) as well as provide stimuli-responsive release of the same upon oral ingestion. The delivery system was designed to endure the chemically and mechanically hostile gastric environment and deliver the drug in the small intestine to improve absorption. A 3 × 3 grid macroporous pill was designed (specifically to withstand the mechanically hostile gastric environment) and 3D printed using Stereolithography comprising of a resin system including acrylic Acid, PEGDA and PEG 400 along with curcumin loaded BSA nanoparticles (Cu-BSA NPs) as a multifunctional additive and TPO as the photoinitiator. The 3D printed macroporous pills were found to show excellent fidelity to CAD design as evident from the resolution studies. The mechanical performance of the macroporous pills was found to be extremely superior to monolithic pills. The pills found to release curcumin in pH responsive manner with slower release at acidic pH but faster release at intestinal pH due to its similar swelling behavior. Finally, the pills were found to be cytocompatible to mammalian kidney and colon cell lines.

Abstract
Disintegration time (DT) and rate of drug dissolution in different media are among the most widely studied crucial parameters for various types of drug products. In the ever-evolving landscape of generic formulation development, dissolution comparison of reference and test products is the major reliable in vitro method of establishing product similarity. This is one of the most widely accepted methods of proving pharma equivalency between two drug products. A well-studied match between the disintegration and dissolution profile of the test and reference formulations can ensure in vitro product similarity. Various statistical approaches have been employed to establish product performance similarity; among them, the similarity factor (f2) calculation based approach is the most widely accepted and explored method to date. However, the f2 statistics fail to predict the similarity of batches with unit-to-unit variability. Bootstrap statistical analysis of dissolution data between the test and reference products was introduced to overcome the problems associated with batches with unit variability. Bootstrap can also be applied to extract statistically significant results by treating a series of data from different batches, which can further help to understand the trend. The current review depicts different case study based approaches to show the applications of bootstrap statistics in disintegration and dissolution similarity evaluation for both conventional and additively manufactured solid dosage forms. It is concluded that bootstrap statistics can be a very promising and reliable data analytical tool for establishing in vitro product similarity for both conventional and additively manufactured formulations with a high level of intraunit variability.

Abstract
Nanotechnology has changed the entire paradigm of drug targeting and has shown tremendous potential in the area of cancer therapy due to its specificity. In cancer, several targets have been explored which could be utilized for the better treatment of disease. Mitochondria, the so-called powerhouse of cell, portrays significant role in the survival and death of cells, and has emerged as potential target for cancer therapy. Direct targeting and nanotechnology based approaches can be tailor-made to target mitochondria and thus improve the survival rate of patients suffering from cancer. With this backdrop, in present review, we have reemphasized the role of mitochondria in cancer progression and inhibition, highlighting the different targets that can be explored for targeting of disease. Moreover, we have also summarized different nanoparticulate systems that have been used for treatment of cancer via mitochondrial targeting.
