AB  - Abstract

Objectives
The aim of our study was to evaluate the effect of designing ketoprofen-loaded nanosized spheres and combining them with solid silicon microneedles for enhanced and sustained percutaneous drug delivery.

Methods
Ketoprofen-loaded nanoparticles (KET-NP) were designed by modified solvent displacement method, using poly (D, L-lactic acid) (PDLLA). All prepared nanoparticles were characterised with regard to their particle size distribution, morphology, surface properties, thermal behaviour, drug content, drug release and stability. In-vitro skin permeation studies were conducted on Franz-type diffusion cells using porcine skin treated with ImmuPatch silicon microneedles (Tyndall Nation Institute, Cork, Ireland).

Key findings
The study showed that uniform nanospheres were prepared with high encapsulation efficiency and retained stable for 2 months. After an initial burst release, the PDLLA nanoparticles were capable of sustaining and controlling ketoprofen release that followed Korsmeyer–Peppas kinetics. An enhanced flux of ketoprofen was observed in the skin treated with silicon microneedles over a prolonged period of time.

Conclusions
Following application of silicon microneedle arrays, KET-NP were able to enhance ketoprofen flux and supply the porcine skin with drug over a prolonged (24 h) period of time. Our findings indicate that the delivery strategy described here could be used for the further development of effective and painless administration systems for sustained percutaneous delivery of ketoprofen.

AB  - The transdermal delivery system provides a highly efficient, safe, and easy to use method for delivering active ingredients and other compounds to the body through intact skin, thereby offering many other advantages over the traditional dosage forms. Ketoprofen is a poorly watersoluble non-steroidal antiinflammatory drug and widely used for the acute and long-term treatment of rheumatoid arthritis and associated diseases. The purpose of the study presented in this paper has been to examine the possibility of the synthesis of a new nanoparticulate system for drug delivery of ketoprofene suitable for transdermal applications. Multi-scale design of a transdermal drug delivery system, from the molecular or nano scale through the macroscopic scale, was analyzed. The obtained nano particles contain ketoprofene-loaded spheres of poly(D,L-lactide acid) (PDLLA). Characterization was performed with wide-angle X-ray structural analysis (XRD), infrared spectroscopy (FT-IR), field-emission scanning electron microscopy (FESEM), high performance liquid chromatography (HPLC) and particle sized distribution (PSD) methods. XRD and FT-IR analyses confirmed that the ketoprofene is immobilized into PDLLA. The encapsulation of ketoprofen into the PDLLA nanoparticles was highly accomplished and the drug loading efficiency was 75%. The observed average particle dimension (d50) of ketoprofene-loaded nano particles was 63 nm.
