Abstract
Oral medication is preferred for its convenience; however, efficient drug delivery remains challenging due to issues such as poor solubility, and absorption caused by mucosal barriers, which result in low bioavailability. In this review, we discuss new strategies integrating robotic capabilities into oral formulations to enhance drug delivery. Such robotic pill systems leverage the efficient propulsion of biological and synthetic micromotors to accelerate pill disintegration and overcome mucosal barriers, increasing bioavailability with lower doses and fewer side effects. In addition, advanced bioinspired robotic capsules, including microneedles, microinjectors, and microjet systems, offer enhanced macromolecule bioavailability comparable with that achieved with subcutaneous injections. The future of precision medicine lies in encapsulating diverse micromotors (with unique capabilities) within pharmaceutical carriers, offering groundbreaking opportunities for enhanced therapeutic interventions.
