Taking an Alternative Approach to Drug Delivery

ABSTRACT

Increased awareness of the carbon footprint associated with pharmaceutical products and the replacement of high global warming potential (GWP) constituents used in the final product, or within the manufacturing process, may drive further diversification of formulation approaches in the future. [...]the nose offers an opportunity to deliver drugs directly to the brain or central nervous system (CNS) via the olfactory pathway. Two relatively recent commercializations for intranasal delivery are naloxone nasal spray to treat suspected opioid overdose emergencies and diazepam nasal spray for short term rescue treatment of seizure clusters. [...]in cystic fibrosis, the overproduction of mucus and alteration of mucus properties, represents a challenge for effective drug delivery by inhalation alone.
