Partition and distribution coefficients of aryloxypropanolamine beta-adrenoceptor antagonists.
n-Octanol/water partition and distribution coefficients of fifteen beta-blockers have been measured and the relationships between log P (neutral species), log Pi (fully ionized species) and log D7.4 have been examined. A strict correlation exists among these three parameters, suggesting that the ionization exerts similar effects on the partition behaviour of these drugs.
