1. First-pass Intestinal Metabolism of Drugs : Experiences from in vitro, in vivo and simulation studies
Sammanfattning : The bioavailability of a drug can be described as the fraction of an orally administered dose that reaches the systemic circulation and is often limited by first-pass metabolism in the gut and the liver. It is important to have knowledge about these processes since the systemic blood drug concentration is tightly connected to the effect of the drug. LÄS MER

Sammanfattning : Pulmonary delivery of drugs is the preferred route of administration for treatment of local lung diseases like asthma and chronic obstructive pulmonary disease. Recently, there has also been increased interest in systemic delivery of drugs via the lungs to avoid problems with low and/or variable gastrointestinal absorption, and as a needle-free alternative for drugs that cannot be ingested.
