Orally disintegrating tablets (ODTs) are designed to dissolve in the oral cavity within 3 min, providing a convenient option for patients as they can be taken without water. Direct compression is the most common method used for ODTs formulations. However, the availability of single composite excipients with desirable characteristics such as good compressibility, fast disintegration, and a good mouthfeel suitable for direct compression is limited. This research was proposed to develop a co-processed excipient composed of xylitol, mannitol, and microcrystalline cellulose for the formulation of ODTs. A total of 11 formulations of co-processed excipients with different ratios of ingredients were prepared, which were then compressed into ODTs, and their characteristics were thoroughly examined. The primary focus was on evaluating the disintegration time and hardness of the tablets, as these factors are important in ensuring the ODTs meet the desired criteria. The model drug, Mirtazapine was then incorporated into the chosen optimized formulation. The results showed that the formulation comprised of 10% xylitol, 10% mannitol and 80% microcrystalline cellulose demonstrated the fastest disintegration time (1.77 ± 0.119 min) and sufficient hardness (3.521 ± 0.143 kg) compared to the other formulations. Furthermore, the drug was uniformly distributed within the tablets and fully released within 15 min. Therefore, the developed co-processed excipients show great potential in enhancing the functionalities of ODTs, offering a promising solution to improve the overall performance and usability of ODTs in various therapeutic applications.

Transdermal Drug Delivery Systems (TDDS) have emerged as a promising method for administering therapeutic agents due to their non-invasive nature and patient-friendly approach. However, the effectiveness of this system is limited to drugs with specific physicochemical properties that allow for transdermal delivery as the skin acts as a barrier. To address this limitation, researchers have been exploring alternative approaches to improve drug delivery through the stratum corneum, ensuring consistent drug distribution at controlled rates. Thirdgeneration delivery systems have been developed to facilitate the delivery of various drugs across the skin barrier by disrupting the stratum corneum while protecting deeper skin tissues from injury. This review has explored various approaches that have gained popularity in enhancing drug delivery through TDDS, including microneedle-mediated, nanoparticle-enabled, thermal ablation-enhanced, and electroporation-driven delivery systems. It has discussed the mechanisms of drug delivery and potential applications for different types of drugs and detailed the clinical studies. This review has also highlighted the significant advancements in TDDS, offering valuable insights into both the pharmaceutical field and biomedical applications. The continued exploration and refinement of these delivery systems, particularly with the incorporation of Internet-of-Things (IoT) technology, Artificial Intelligence (AI), and machine learning, hold promise for expanding the scope of therapeutic interventions., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

For decades, cocoa butter has been extensively used in food industries, particularly in the production of chocolate confectioneries. The composition of fats within cocoa butter, such as stearic acid, palmitic acid, and oleic acid, determines its properties. Studies have indicated the existence of at least six polymorphic forms of cocoa butter, each possessing distinct characteristics and melting points. Recently, cocoa butter has garnered attention for its potential as a delivery system for pharmaceutical products. This review thoroughly explores cocoa butter, encompassing its production process, composition, properties, and polymorphism. It delves into its diverse applications across various industries including food, cosmetics, and pharmaceuticals. Additionally, the review investigates cocoa butter alternatives aiming to substitute cocoa butter and their roles in different drug delivery systems. The unique properties of cocoa butter have sparked interest in pharmaceutical industries, particularly since its introduction as a drug delivery system and excipient. This has prompted researchers and industry stakeholders to explore novel formulations and delivery methods, thereby expanding the range of options available to consumers in the pharmaceutical market., Competing Interests: The authors declare that they have no conflict of interest., (Thieme.
