Km. Wasan et Sm. Cassidy, ROLE OF PLASMA-LIPOPROTEINS IN MODIFYING THE BIOLOGICAL-ACTIVITY OF HYDROPHOBIC DRUGS, Journal of pharmaceutical sciences, 87(4), 1998, pp. 411-424
The plasma lipoprotein distribution of potential drug candidates is no
t commonly studied. For some hydrophobic drug candidates, attainment o
f similar plasma free drug levels has not been associated with uniform
production of pharmacological activity in different animal species. I
t is well-known that plasma lipoprotein lipid profiles vary considerab
ly between different animal species. In addition, human disease states
can significantly influence plasma lipoprotein profiles, resulting in
altered therapeutic outcomes. Current research has shown that lipopro
tein binding of drug compounds can significantly influence not only th
e pharmacological and pharmacokinetic properties of the drug, but the
relative toxicity as well. Elucidation of drug distribution among plas
ma lipoproteins is expected to yield valuable insight into factors gov
erning the pharmacological activity and potential toxicity of the drug
. This paper will present an historical perspective and summarize the
latest research in the area of lipoprotein-drug interactions.
