DESIGN AND ADVANCEMENTS OF IMPLANTABLE DRUG DELIVERY SYSTEM

Raji Kakarlamudi — 2026-05-04

Conventional drug delivery systems often provide limited control over drug release profiles, resulting in fluctuating plasma concentrations, reduced therapeutic efficacy, and increased adverse effects. To overcome these limitations, Novel Drug Delivery Systems (NDDS) have been developed, among which Implantable Drug Delivery Systems (IDDS) represent a promising approach for controlled, targeted, and sustained drug administration. The reviewed studies highlight the design, materials, mechanisms, and applications of implantable systems, including polymeric implants and advanced magnetically actuated soft capsule robots. These systems enable zero-order or programmable drug release directly at the site of action, minimizing systemic exposure and improving patient compliance. Shape-programmable and magnetically controlled capsules demonstrate the potential for gastric retention, safe tissue interaction, and controlled drug release, followed by safe elimination from the body. IDDS are particularly beneficial for drugs with poor oral bioavailability, enzymatic degradation, or narrow therapeutic windows, such as insulin, steroids, and anticancer agents. Applications span multiple therapeutic areas including oncology, ophthalmology, dentistry, and contraception. Despite their advantages-such as reduced dosing frequency, improved efficacy, and targeted delivery-high cost, complex design, and the need for extensive clinical validation remain significant challenges. Continued research and technological refinement are essential to enhance safety, affordability, and large-scale clinical adoption of implantable drug delivery systems.

IMPORTANCE OF BIODEGRADABLE POLYMERS IN MODERN PHARMACEUTICAL DRUG DELIVERY TECHNOLOGIES

Vikram Kamalakuru — 2026-05-16

In modern drug delivery systems, biodegradable polymers have gained significant importance due to their ability to safely decompose into non-toxic byproducts after fulfilling their therapeutic purpose. These polymers facilitate controlled and sustained drug delivery, improve bioavailability, and enable targeted delivery, thereby enhancing therapeutic effects while minimizing side effects. Commonly utilized biodegradable polymers include natural varieties such as chitosan, alginate, and gelatin, as well as synthetic options like polylactic acid (PLA), polyglycolic acid (PGA), and their copolymers. The composition, molecular weight, and crystallinity of these polymers can be adjusted to achieve precise control over drug release kinetics, as they can be engineered to influence degradation behavior. Biodegradable polymer-based carriers are widely employed in various drug delivery systems, including microspheres, nanoparticles, hydrogels, implants, and gastroprotective systems. They are particularly beneficial in managing chronic diseases, especially in cancer treatment, as they reduce dosing frequency and enhance patient compliance. Furthermore, biodegradable polymers eliminate the need for surgical removal of delivery devices, offering significant clinical advantages. Despite their promising applications, challenges related to stability, scalability, and reproducibility remain. Overall, biodegradable polymers represent a versatile and effective approach to designing drug delivery systems and continue to play a crucial role in pharmaceutical research and development.

The relevant biological activities, source organisms and country of origin. Pertinent reviews, biosynthetic studies, first syntheses, and synthesis that led to the revision of structures or stereo chemistries, have been included. analysis of the progress in the study of prokaryote involvement in macro-invertebrate MNP production is discussed. The biomedical potential of the sea has gone largely unexplored so far, despite the globe that it covers three parts of the planet surface and the fact that life on Earth originated from the sea. However, with the help of the professional deep sea divers, the marine researchers have archived access to all sorts of marine creatures like sponges, corals, sea urchins, sea squirts, hydroids, sea anemones, fishes and mollusks as well as to varied types of sea plants including algae and the other micro-organisms embedded in the sea bed. New Advancements in synthetic biology, genomic sequencing and bioinformatics are entitiling innovative solutions to these challenges, facilitating the identification, characterization, and sustainable production of marine bioactive compounds. versatile collaborations and public-private partnerships are essential for translating MNP discoveries into viable clinical applications. The results highlighted the overlooked prospective of marine natural products as high in resources for innovative solutions in the phase of escalating drug resistance and vacant void of therapeutic needs.

TRANSDERMAL DRUG DELIVERY SYSTEM: A COMPREHENSIVE OVERVIEW OF RECENT PROGRESS AND ENHANCEMENT STRATEGIES

Kiran Kumar Kompala — 2026-05-23

Transdermal drug delivery systems have emerged as a research issue of interest in the pharmaceutical technology field, as well as one of the most commonly procured pharmaceutical products in the global market. The associated disadvantages of other delivery routes, including oral and parenteral, can be overcome by the use of these systems. The authors will examine the existing tendencies and the way transdermal technologies will be applied in the future, paying particular attention to the development of detailed insight into transdermal drug delivery systems and improvement strategies. The largest organ in the body is the skin, which is a good location for the administration of several medicines. There are various benefits of transdermal drug delivery systems compared to traditional delivery systems. Also, transdermal drug delivery systems [TDDS] offer extended therapeutic levels, decreased side effects, elevated bioavailability, elevated patient compliance, and simple discontinuation of drug treatment. In the article, I will first discuss each of the transdermal enhancement procedures applied in the creation of first-generation transdermal products.

Nanotechnology has emerged as a transformative approach in the cosmeceutical industry,offering innovative solutions to overcome the limitations of conventional cosmeticformulations. The integration of nanoscale delivery systems has significantly theefficacy, stability, and safety of active cosmetic ingredients. This review enhanced analyses recent research on nanotechnology-based cosmeceuticals, focusing on widely used nanocarriers such as liposomes, Nano emulsions, Niosome, Nano capsules, solid lipid nanoparticles, nanostructured lipid carriers, and nanocrystals. These systems improve skin penetration, provide controlled and sustained release, enhance bioavailability of poorly soluble actives, and protect sensitive compounds such as vitamins, antioxidants, and UV filters from degradation. Nano cosmeceuticals have found extensive applications in skin, hair, nail, and lip care, particularly in anti-aging, photoprotection, moisturization, hyperpigmentation, and hair damage management. Despite their advantages, concerns regarding nanoparticle toxicity, skin permeation, long-term exposure, and environmental impact remain significant. Regulatory challenges and the lack of standardized safety assessment protocols further complicate their widespread adoption. Overall, nanotechnology presents substantial potential for advancing cosmeceutical performance, but balanced development supported by rigorous toxicological evaluation and regulatory frameworks is essential for safe and sustainable commercialization.
