Q

In a new trial, why does orally administered drug have lower area under curve than iv?

A

First pass hep metabolism: The drug is absorbed from the GI tract and passes via the portal vein into the liver where some drugs are metabolised. Sometimes the result of first pass metabolism means that only a proportion of the drug reaches the circulation Alternative routes of administration like suppository, intravenous, intramuscular, inhalational aerosol, transdermal, buccal and sublingual avoid the first-pass effect because they allow drugs to be absorbed directly into the systemic circulation.

55
Q

In RCT, if there is a large nocebo effect, what does this mean?

Eg anticipating side effects of a medication -> ptn suffers that effect even if the “medication” is actually an inert substance
