Introduction: The pharmaceutical technologists face a lot of challenges and limitations when designing novel drug delivery systems such as low oral bioavailability of many drugs, primarily due to poor solubility, slow dissolution rates, limited permeability through gastrointestinal mucosa, and rapid degradation within the body. Areas covered: The biopharmaceutical classification (BCS) classification represents a map in drug delivery research. Numerous active ingredients are characterized by low bioavailability due to poor water solubility, especially active ingredients of BCS class II and IV. Self-emulsifying drug delivery systems (SEDDS) could act as game changer in order to overcome the challenges and limitations of poor bioavailability. In this review, timelines representing the launch of self - emulsifying drug delivery systems, their introduction to the pharmaceutical platform and their benefits will be discussed in detail.
Expert Opinion: The development of multifunctional systems capable of combining controlled release, targeted delivery, and diagnostic capabilities is a promising avenue. As the technology matures, self-microemulsifying drug delivery systems and self-nanomulsifiying drug delivery systems are likely to become a standard approach for delivering BCS class II and IV drugs, transforming the pharmaceutical landscape.

Platinum-based chemotherapy, despite being a cornerstone of cancer treatment, faces significant challenges due to acquired drug resistance. To address this issue, we have designed three organelle-targeting platinum(IV) prodrugs conjugated with BODIPY fluorophores, enabling spatiotemporal control through green light irradiation. These BODIPY-Pt(IV) conjugates exhibit excellent stability in PBS buffer, demonstrating resilience under physiological conditions.

This is the fourth paper in a series describing an inhalation biopharmaceutics classification system (iBCS), an initiative supported by the Product Quality Research Institute. The paper examines the application of the inhalation Biopharmaceutics Classification System (iBCS) through the drug discovery, development, and postapproval phases for orally inhaled drug products (OIDP) and for the development of generic OIDPs. We consider the implication of the iBCS class in terms of product performance and identify the practical gaps that must be filled to enable the classification system to be adopted into day-to-day practice.

Micro/Nanorobots(MNRs)integrated with phototherapy represent an emerging approach to cancer treatment and hold significant potential for addressing bacterial infections, neurological disorders, cardiovascular diseases, and related conditions. By leveraging micro/nanoscale motor systems in conjunction with phototherapy, these robots enable real-time guidance and monitoring of therapeutic processes, improving drug delivery precision and efficiency. This integration not only enhances the effectiveness of phototherapy but also minimizes damage to surrounding healthy tissues.
