This narrative review discusses surface modification strategies for oral liposomes. These strategies include synthetic polymer modifications, natural biomacromolecule modifications, small-molecule ligand modifications, and composite or multi-layer modification strategies.
The study does not report on specific populations, sample sizes, or primary outcomes because it is a review of existing information rather than a clinical trial. No specific medications or conditions were listed in the provided data.
The main reason to be careful is that the review highlights significant challenges ahead. Overcoming industrial scale-up bottlenecks and conducting rigorous long-term biosafety evaluations are described as pivotal for future clinical and commercial success. Without these steps, the potential benefits of these technologies cannot be realized in practice.
Readers should understand that this is a narrative review with no reported safety data or adverse events. The evidence is limited to general statements about future requirements. There is no proof that these strategies work yet, only a call for further evaluation.
