摘要

We report on the deposition of triacetate-pullulan polysaccharide thin films on drug pellets (diclofenac sodium) by matrix assisted pulsed laser evaporation method. The radiation generated by a pulsed excimer KrF* laser source (λ=248 nm, τ = 20 ns) operated at 2 Hz repetition rate was used for ice targets evaporation. The timed - controlled drug delivery was proved by spectroscopic in vitro studies and in vivo anti-inflammatory investigations on rabbits. We showed that the coating of drug pellets with triacetate-pullulan thin films resulted in the delayed delivery of the drug for up to 30 min.
