Integration of Liposomal Carriers, Nanoparticles, Oral Dosage Technologies, and Controlled Release Formulations in Modern Drug Delivery

Modern drug delivery systems' evolution has drastically altered the paradigm from traditional dosage forms to the corresponding engineered technologies that are specifically made for controlled, targeted, and patient-centered therapies. The present article encompasses those liposomal carriers, nanoparticulate systems, oral fast dissolving technologies, and controlled release formulations that altogether shape the future of the therapeutic delivery. The intro gives a deciphering of the ideas of logical drug design and controlled targeting. The vesicular and liposomal systems are discussed in terms of their structural, biomedical, and clinical importance, after which the particle-based methods that sharpen therapeutic precision and conquer the barriers to macromolecular delivery are discussed. Lipid-based nanocarriers like solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs) show their edge over others by maintaining exceptional stability, encapsulation efficiency, and continuous drug release characteristics. Besides that, oral fast-acting systems—which consist of mouth-dissolving tablets, films, and effervescent preparations—are characterized by their quick start and increased patient compliance coupled with chewable forms for easier acceptance. Among these reliable and sustained-release techniques are microencapsulation, pulsatile multiparticulate systems, and matrix-based designs that provide constant pharmacokinetic performance and help in keeping the patient. The article ends with clinical viewpoints on nanocarrier usage that are connecting preclinical innovations with clinical success. This whole synthesis marks that the interplay between formulation science and therapeutic outcomes is very strong and points out the fact that a patient-oriented approach is essential in pushing the next-generation drug delivery systems forward.
