Abstract
Recent Updates in the Formulation Strategies to Enhance the Bioavailability of Drugs Administered via Intranasal Route
Narendar Dudhipala, Arjun Narala and Ramesh Bomma
Targeting drugs to the brain or Cerebrospinal fluid (CSF) is limited because of the physiological barriers like blood-brain barrier and blood-CSF barriers. Alternative non-invasive, patient compliant delivery routes like intranasal route was investigated by several research groups to target both small and large molecules. Several barriers that limit the bioavailability and research formulation strategies adopted by various research groups are discussed in brief in this review article.
