Nano-liposomes of entrapment lidocaine hydrochloride on in vitro permeability of narcotic.

In order to explore two kinds of nano-liposomes in lidocaine hydrochloride nano-liposomes on in vitro permeability of drug, and conduct comparison and analysis, this paper investigates cumulative infiltration situation of lidocaine hydrochloride flexible nano-liposomes and ordinary nano-liposomes by using modified Franz diffusion pool on mice vitro skin. Cumulative osmotic quantity of lidocaine hydrochloride flexible nano-liposomes for 9h was higher than ordinary nano-liposomes. (t)max(Maximum osmotic quantity time) of lidocaine hydrochloride flexible nano-liposomes and ordinary nano-liposomes in mice skin was 5 and 60min, the former (C)max (maximum dosage time) was 1.2 times of the latter. Drug was not found in mice plasma of ordinary nano-liposomes group, traces of drugs was detected in 0.5 and 1h in flexible nano-liposomes group, but the concentration was lower than the effective concentration. Compared with the classic skin transparent promoter and ordinary liposome, flexible nano-liposomes have more advantages, but its stability is less than ordinary nano-liposomes because of the addition of surface active substance. Flexible nano-liposomes have great development potential as a carrier of transdermal drug delivery field.
