DOI 10.1007/s11095-008-9578-3

An error in the article title was published in the HTML version of the article and the article abstract page: Flux Across of Microneedle-treated Skin is Increased by Increasing Charge of Naltrexone and Naltrexol In Vitro.

The first “of” should not be included in the title. The pdf version of the article was published with the correct title.
