Liposomal Formulations for Inhalation

• “Nanopackaging” of drugs
• Sustained release within lung
• Ideal for AERx platform
• Applicable to multiple products

Aradigm’s liposome formulations are nano-size liquid vesicles made out of lipids that encapsulate drugs. When the drug in these vesicles is deposited in the respiratory tract, it is slowly released, with the view to provide sustained delivery of the drug at the site of action and only minimum concentration of the drug in the rest of the body. Purposeful formulations of liposomes can also achieve preferential targeting of drugs to certain cell types, maximizing the efficacy of and minimizing the toxicity of the drug.
