KPV Transport Across Microporated Human Skin In Vitro
Researchers compared iontophoresis, microneedle treatment and their combination for moving KPV across excised human skin.
Study design
Dermatomed human skin was tested in diffusion equipment. The team varied current strength, KPV concentration and application time, measured permeation and retention, and used fluorescent KPV to examine penetration depth.
What the researchers reported
Passive permeation was below the study's detection threshold. Microneedles increased delivery, while iontophoresis combined with microneedles produced the highest reported permeation rate under the tested conditions.
What this result does not establish
This ex vivo delivery experiment did not test biological efficacy, tolerability in living participants or clinical outcomes. Results apply to the specific devices and parameters used.
This article summarizes one published study about KPV. It does not establish clinical efficacy, general safety, regulatory approval or suitability for human use. Findings should be interpreted within the model, methods and limitations of the original paper.
