Nasal implants for drug delivery: Advancements and applications

Abstract

Nasal implants have emerged as a pioneering technology for nasal drug delivery systems. These are breakthrough options made of biocompatible materials that are temporarily inserted into the nasal passages for both functional and cosmetic purposes. Drug-eluting nasal implants are beneficial for improving patient compliance, reducing the need for repeated drug administration, and achieving controlled release of therapeutic agents. This article offers a comprehensive insight into nasal implants and their applications, and addresses a patent perspective in the same context. Important considerations for clinically approved implants, such as Propel, Sinuva, Sinu-Foam, and Relieva Stratus, have also been discussed.
