A method of transdermal drug delivery using drug formulations and other small molecules is described. The drug or other small molecule formulation is applied to the skin of a patient using a radio frequency device. The radio frequency device facilitates the ablation of the stratum corneum allowing the drug or other small molecule to pass to the underlying skin. The drug or small molecule can be contained in hyaluronic acid nanoparticles or suspended in a gel.

Method of transdermal drug delivery

The present invention relates to the development of a hyaluronic acid and hyaluronic acid hybrid nanoparticle systems for the administration of active molecules, peptides, DNA and/or other hydrophilic or hydrophobic molecules, the composition of hyaluronic acid and hyaluronic acid hybrid nanoparticle systems, and the procedure for their development and use. These nanoparticles are made up of hyaluronic acid in salt form, preferentially the sodium salt of the polymers or hybridized with magnetic Fe particles. The nanoparticles are basically from natural polymers, biocompatibles and biodegradables. The nanoparticles allow the controlled release of the active molecules they transport and their orientation towards the target tissues. The present invention teaches a procedure to elaborate particles of hyaluronic acid with a diameter less than 180 nm., that incorporate an active ingredient, independent of its hydrophilic or hydrophobic nature. Procedures to produce the particles are described. The present invention will be useful in methods of transdermal drug delivery using hyaluronic acid nanoparticles, among other uses.
