Title

Different inorganic nanoparticles as enhancers for dermal delivery of proteins in pharmaceutical and cosmetic products

English Abstract

Objectives: In last decades dermal delivery of drugs has attracted a great interest. In this study Calcium phosphate nanoparticles (CaP-NPs), Zinc oxide nanoparticles (ZnO-NPs) and some organic solvents were used as combination enhancers for dermal delivery of albumin. Methods: Formulations contained albumin, solvent, CaP-NPs and/or ZnO-NPs. Permeation of albumin was determined by an ex-vivo (animal skin) method. Distribution of the NPs in the skin layers was depicted by optical microscopic method. Results: Among solvents, liquid paraffin (LP) showed the greatest increase in albumin permeation (total permeation of 384 mg). CaP-NPs and ZnO-NPs also increased the albumin permeation (19 and 22 mg, respectively). Combination of these NPs and LP further increased the albumin permeation (470 and 487 mg, respectively). Conclusion: All solvents increased albumin permeation while LP showed a dramatic increase. CaP-NPs or ZnO-NPs also increased the permeation. Enhancing mechanism of the NPs was attributed to their deposition through skin layers shown by images. Using a combination of CaP-NPs and/or ZnO-NPs with LP caused synergistic permeations following by a saturation at a high dose of the NPs. The study suggests simultaneous use of proper doses of such inorganic NPs with LP to considerably enhance dermal delivery of albumin or other proteins.
