The implementation of this groundbreaking methodology has significantly revolutionised the controlled and precise delivery of therapeutic interventions. An in-depth investigation is conducted into the most recent developments in ultrasonic stimulus-responsive materials and techniques for the purpose of accomplishing precise medication administration. The investigation begins with an exhaustive synopsis of the foundational principles underlying drug delivery systems that react to ultrasonic stimuli, focusing specifically on the complex interplay between polymers and ultrasound waves. Significant attention is devoted to the development of polymers that demonstrate tailored responsiveness to ultrasound, thereby exemplifying their versatility in generating controlled drug release patterns. Numerous classifications of intelligent polymers are examined in the discussion, including those that react to variations in temperature, pH, and enzymes. When coupled with ultrasonic stimuli, these polymers offer a sophisticated framework for the precise manipulation of drug release in terms of both temporal and spatial dimensions. The present study aims to examine the synergistic effects of responsive polymers and ultrasound in overcoming biological barriers such as the blood-brain barrier and the gastrointestinal tract. By doing so, it seeks to shed light on the potential applications of these materials in intricate clinical scenarios. The issues and future prospects of intelligent ultrasound-responsive polymers in the context of drug delivery are critically analysed in this article. The objective of this study is to offer valuable perspectives on the challenges that must be overcome to enable the effective implementation of these technologies. The primary objective of this comprehensive review is to furnish researchers, clinicians, and pharmaceutical scientists with a wealth of information that will serve as a guide for forthcoming developments in the development and enhancement of intelligent drug delivery systems that employ ultrasound-responsive polymers to attain superior therapeutic outcomes.</p>","PeriodicalId":94287,"journal":{"name":"Current drug delivery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139577198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Particle size, surface charge, biocompatibility, drug capacity, and mucoadhesive are unique chemical and physical features that must be considered for pulmonary and nasal delivery routes due to anatomical and permeability considerations. The traditional management of numerous chronic diseases has a variety of drawbacks. As a result, targeted medicine delivery systems that employ nanotechnology enhancer drug efficiency and optimize the overall outcome are created. The pulmonary route is one of the most essential targeted drug delivery systems because it allows the administering of drugs locally and systemically to the lungs, nasal cavity, and brain. Furthermore, the lungs' beneficial characteristics, such as their ability to inhibit first-pass metabolism and their thin epithelial layer, help treat several health complications. The potential to serve as noninvasive self-administration delivery sites of the lung and nasal routes is discussed in this script. New methods for treating respiratory and some systemic diseases with inhalation have been explored and highlight particular attention to using specialized nanocarriers for delivering various drugs via the nasal and pulmonary pathways.
