1. Olfactory Transfer of Analgesic Drugs After Nasal Administration
Sammanfattning : Nasal administration of analgesics for achieving rapid pain relief is currently a topic of great interest. The blood-brain barrier (BBB) restricts access to the central nervous system (CNS) for several central-acting drugs, such as morphine and dihydroergotamine, which results in a substantial effect delay.

2. Nasal administration of compounds active in the central nervous system : Exploring the olfactory system
Sammanfattning : The nasal administration of drugs offers advantages over administration by intravenous injection. Drugs can be rapidly absorbed through the nasal mucosa, resulting in a rapid onset of action, and also avoiding degradation in the gastrointestinal tract and first-pass metabolism in the liver.

3. Models for the Transfer of Drugs from the Nasal Cavity to the Central Nervous System
Sammanfattning : The blood-brain barrier restricts the access of many compounds, including therapeutic agents, to the brain. Several human studies indicate that nasal administration of hydrophilic compounds, such as peptides, can bypass the blood-brain barrier. The aims of this thesis were to develop and refine models for this direct nose-to-brain transfer. LÄS MER
4. Nasal Drug Delivery : In Vitro Studies on Factors Influencing Permeability and Implications on Absorption
Sammanfattning : Nasal delivery is a feasible alternative to oral or parenteral administration for some drugs because of the high permeability of the nasal epithelium, rapid drug absorption across this membrane and avoidance of hepatic first-pass metabolism. The main objective of this thesis was to investigate factors influencing the permeability of the nasal mucosa to various compounds and to evaluate implications for drug absorption via the nasal route.
