The OPPLC was prepared by solvent evaporation method using binding ratio of OP and phospholipid as evaluation parameter.

The mechanism of the interaction of antibiotics with organic dye molecules was originally discussed, and the binding ratio and binding constant were also calculated.

The enantiomer-specific structure of local anaesthetics has large impact on the pharmacokinetic process of these drugs, including absorption, protein-binding ratio, metabolism, and so on.
