what is lipophilicity of a drug
Lipophilicity is possibly the lost important physicochemical property of a potential drug, it plays a role in solubility, absorption, membrane penetration, plasma protein binding, distribution, CNS penetration and partitioning into other tissues or organs such as the liver and has an impact on the routes of clearance.owever the majority of known drugs contain ionisable groups and are likely to be charged at physiological pH and LogP only correctly describes the partition coefficient of neutral (uncharged) molecules. LogD the distribution constant is a better descriptor of the lipophilicity of a molecule.
