Drug Delivery Research Exploring Liposomal Systems, Nanoparticle Technologies, Oral Formulations, and Controlled Release Mechanisms

Drug delivery systems have come a long way and have developed tremendously with the introduction of bioavailability, targeted delivery, and patient compliance challenges. The article gives a comprehensive review of the recent technological advancements in vesicular carriers, nanoparticle platforms, solid lipid systems, and new oral dosage forms. Liposomal and proniosomal vesicular systems allow delivery of sensitive drugs, targeted delivery, and controlled release while nasal-pulmonary routes open up the treatment methods for respiratory diseases. The use of polymeric and inorganic nanoparticles has removed the barriers in oral administration of peptide and protein and allowed the delivery to specific sites, thus increasing therapeutic efficacy. Solid lipid nanoparticles and nanostructured lipid carriers have the property of being both biocompatible and sustained release, and hence they can serve both systemic and local drug delivery needs.Mouth-dissolving tablets, effervescent formulations, chewable tablets, and multiparticulate/pulsatile systems are among the innovative oral dosage forms that not only improve patient adherence but also permit customizable pharmacokinetic profiles. Along with controlled and sustained release strategies, like fast-dissolving tablets and liposomal vesicular carriers, material science is fused with clinical needs, leading to decreased dosing frequency and supporting chronotherapeutic regimens. The technologies used in oral dosage forms collectively show a shift towards precision medicine in the sense that they are patient-centric and result in better therapeutic outcomes.These systems not only point out the possible scenario of safer, more effective, and convenient therapies but at the same time also show a good link between the pharmaceutical innovation and clinical application. Novel oral drug delivery systems, nanocarriers, and vesicular platforms research would still be the potential areas in which drug delivery efficiency would be further enhanced and clinical impact stretched across various therapeutic areas.
