OK. Among the popular ones do you know which is which or do
you have a reference. Thanks.
According to some articles the more lipid-soluble the
statin, the greater propensity it has to cross the blood-
brain barrier and affect the central nervous system.
According to some reports simvastatin is the most lipophilic
drug in its class; pravastatin is the least lipophilic. Some
reports state that atorvastatin does not cross the blood-
brain barrier, whereas others state that the drug has
intermediate lipophilicity.
My educated guess is that at least lovastatin, mevastatin,
and simvastatin can cross the b-b-b and at least pravastatin
cannot, but I could be wrong.
