WebAug 7, 2012 · The classic example of enhanced permeability through the BBB by increasing lipophilicity is that of morphine and heroin. Modification of morphine (Log P 0.99) to heroin by acetylation of 3- and 6-hydroxy groups results in an increase in log P to 2.3 and >100 times increased lipophilicity. WebProtein-Binding. A common factor impacting distribution of medication is plasma protein in the blood. Albumin is one of the most important proteins in the blood. Albumin levels can … Only the unbound fraction of the drug undergoes metabolism in the liver and other tissues. As the drug dissociates from the protein, more and more drug undergoes metabolism. Changes in the levels of free drug change the volume of distribution because free drug may distribute into the tissues leading to a decrease in plasma concentration profile. For the drugs which rapidly undergo metabolism, clearance is dependent on the hepatic blood flow. For drugs which slowly undergo m… daily tv mass oct 7 2022
