Abstract
This review describes lipophilicity parameters used in drug designing. Lipophilicity is an important parameter related to drug properties, such as drug absorption, plasma protein binding, hydrophobic drug-receptor interactions and partly the pharmacokinetic behaviour and toxicological properties and recognized today as one of the major challenges in oral delivery of new drug substances. The tremendous knowledge accumulated on biological factors and as well as on the physicochemical characteristics of the drug substances lipophilcity affecting oral bioavailability. The new methods (RP-HPLC, RP-TLC, Liposomes partitioning, IAM Chromatography, Electrokinetic approaches) have been discussed to measure the lipophilicity of xenobiotics and to overcome the problems with existing methods.
