Describe drug distribution in relation to protein binding - CORRECT-
ANSWERSProtein binding- Most drugs form a compound and bind with
plasma proteins. Drug molecules bound to plasma proteins are
pharmacologically inactive. Only the free or unbound portions of the drug
acts on the cells. Protein binding allows for some of the drug to be stored
and others to be released as needed. This gives the constant blood level and
decreased risk for toxicity.
High binding=high duration of action.
