PharmaShell® is an advanced drug delivery system developed by Nanexa AB, utilizing Atomic Layer Deposition (ALD) technology to enclose drug particles with an ultra-thin, dense inorganic coating. This innovative approach allows for precise control over the release of active pharmaceutical ingredients (APIs), enabling extended and consistent drug delivery over days, weeks, or even months. By converting immediate-release formulations into long-acting injectables, PharmaShell® enhances patient convenience, reduces side effects, and improves treatment adherence. The technology supports low injection volumes, high drug load, and the use of thin gauge needles, making it less invasive and more comfortable for patients. Additionally, PharmaShell® offers high storage stability, ensuring the integrity and efficacy of the drug over time. The technology is versatile, accommodating various APIs, including biologics, and is particularly beneficial for drugs sensitive to hydrolysis or requiring low injection volumes. PharmaShell® represents a significant advancement in delivery science, offering smarter, more sustainable healthcare solutions.
