Absorption or Distribution
Distribution
Lipid Soluble vs Water Soluble◦
Blood Brain Barrier, Placenta are
Protein Binding , or Permeability, or Circulation
Permeability
Free vs Bound Drug are
Protein Binding , or Permeability, or Circulation
Protein Binding
Diseases that alter circulation
Protein Binding , or Permeability, or Circulation
Circulation
Easily distribute into fatty tissues where they may store or concentrate
Have the potential to cross the Blood Brain Barrier (BBB) and the Placenta
Lipid Soluble or Water Soluble
LS
Typically remain in highly vascularized spaces and can easily leave the body via elimination (urine!)
Lipid Soluble or Water Soluble
WS
Some drugs preferentially bind to protein/albumin Called “low or highly bound drugs“
highly
Drug is not bound to albumin
-can distribute into extravascular tissue to its intended target
Free or Bound drug
Free
Stuck to albumin, stays in the bloodstream
◦Cannot get to extravascular space and reach intended target
