Targeted Drug

Nanotechnology is making significant transformation to our world, especially in healthcare and the treatment of diseases. It is widely used in different medical applications, such as in treatment and detection. Targeting diseased cell with nanomedicines is one of the numerous applications of nanotechnology. Targeted drug delivery systems for delivering various types of drugs to specific sites are such a dynamic area in pharmaceutical biotechnology and nanotechnology. Compared to conventional drugs, nanomedicines have a higher absorption and bioavailability rate, improving efficacy and minimizing side effects. There are several drug delivery systems including metallic nanoparticles, polymers, liposomes, and microspheres, but one of the most important is the niosomes, which are produced by nonionic surfactants. Because of the amphiphilic nature and structure, hydrophilic or hydrophobic drugs can be loaded into niosome structures. Other compounds, including cholesterol, can also be applied to the niosomes' backbone to rigidize the structure. Several variables such as the type of surfactant in niosome production, the preparation method, and the hydration temperature can affect the structure of the niosomes. Nevertheless, in-silico design of drug delivery formulations requires molecular dynamic simulation tools, molecular docking, and ADME (absorption; distribution; excretion; metabolism) properties, which evaluate physicochemical features of formulation and ADME attitudes before synthesis, investigating the interaction between nano-carriers and specific targets. Hence, experimenting in-vitro and in-vivo is essential. In this review, the basic aspects of niosomes are described including their structure, characterization, preparation methods, optimization with in-silico tools, factors affecting their formation, and limitations.

Background: Recent past decades have reported emerging of polymeric nanoparticles as a promising technique for controlled and targeted drug delivery. As nanocarriers, they have high drug loading and delivery to the specific site or targeted cells with an advantage of no drug leakage within en route and unloading of a drug in a sustained fashion at the site. These stimuli-responsive systems are functionalized in dendrimers, metallic nanoparticles, polymeric nanoparticles, liposomal nanoparticles, quantum dots. Purpose of Review: The authors reviewed the potential of smart stimuli-responsive carriers for therapeutic application and their behavior in external or internal stimuli like pH, temperature, redox, light, and magnet. These stimuli-responsive drug delivery systems behave differently in In vitro and In vivo drug release patterns. Stimuli-responsive nanosystems include both hydrophilic and hydrophobic systems. This review highlights the recent development of the physical properties and their application in specific drug delivery. Conclusion: The stimuli (smart, intelligent, programmed) drug delivery systems provide site-specific drug delivery with potential therapy for cancer, neurodegenerative, lifestyle disorders. As development and innovation, the stimuli-responsive based nanocarriers are moving at a fast pace and huge demand for biocompatible and biodegradable responsive polymers for effective and safe delivery.

Introduction: The development of safe drug delivery systems for a therapeutic agent with less side effects and more bioavailability to the targeted site is very vital in drugs formulation. Tinidazole (TZ) is a drug used to treat giardiasis, amebiasis for colon infections and other infections also such as trichomoniasis, bacterial vaginosis. But the oral bioavailability for the current using drugs low. So, the current study was aimed to develop colon targeted drug delivery system for Tinidazole (TZ) with polymeric nanoparticles (NPs). Methodology: The nanoparticles formulations of TZ were prepared with modified ionic gelation method using chitosan and hydroxypropyl methylcellulose phthalate (HPMCP) are in different combinations by magnetic stirring method followed by temperature modulated solidification. The solvent evaporation method applied to coat TZ nanoparticles with Eudragit S100. The prepared TZ nanoparticle were studied to evaluate physiochemical properties, In-vitro drug release, mucopenetration and In-vivo mucoadhesive studies were carried out. Results: The results of study indicate, 1:1 ratio of chitosan and HPMCP formulation of nanoparticles provides better spatial interaction between them and TZ with spherical porous and the particles size was diverging between 202 - 236 nm. In vitro release of TZ followed Higuchi and first order equations better than zero order equation. The drug release results of nanoparticles formulations of TZ indicate that the NPs have potential as a drug delivery system compare to uncoated TZ and coated nanoparticles have comparatively less mucoadhesive detachment force. Conclusion: In conclusion, the study was an evidence to use nanoparticles in colon targeted drug delivery systems for better bioavailability of drugs at targeted site and the biodistribution properties of drugs using nanoparticle will be depend on their composition, particle size and their adhesive abilities.

Background: Many efforts have been explored in the last decade to treat colon cancer but nanoparticulate drug delivery systems are making a vital contribution in the improvement of drug delivery to colon cancer cells. Objective: In this review, we attempt to highlight recent advancements in the development of novel drug delivery systems of nanoparticles for the targeted drug delivery to colon. Polymers like Epithelial Cell Adhesion Molecule (EpCAM) aptamer chitosan, Hyaluronic Acid (HA), Chitosan (CS)– Carboxymethyl Starch (CMS), silsesquioxane capped mesoporous silica, Near IR (NIR) fluorescent Human Serum Albumin (HAS), poly(ethylene glycol)-conjugated hyaluronic acid etc. have been discussed by employing various anticancer drugs like doxorubicin, oxaliplatin, paclitaxel, 5-fluorouracil etc. Conclusion: These novel drug delivery systems have been determined to be more efficacious in terms of stability, sustained and targeted drug delivery, therapeutic efficacy, improved bioavailability and enhanced anticancer activity.
