Painless skin patch to deliver the flu medicine zanamivir

Novel, Self-Applied MicroArray Patch (MAP) of Zanamivir for Treatment of the Flu

NIH-funded research Tsrl, INC. · NIH-11171506

A small, self-applied skin patch delivers the flu drug zanamivir to people with influenza, especially those who can't use inhaled medicines.

What this research studies

Researchers are developing a tiny microarray patch (MAP) with microscopic projections that lets zanamivir pass through the skin into the bloodstream. The patch is designed for self-application so people can get the medicine without inhaling it or getting injections. The team will formulate the drug for the patch, test how well it releases and is absorbed through skin in lab and preclinical work, and refine dose and safety before moving toward human testing. The goal is an easy-to-use option for treating flu, including for older adults and people with lung problems who cannot use inhalers.

Who could benefit from this research

Good fit: People with confirmed or suspected influenza or those at high risk of complications who cannot use inhaled antiviral therapies would be the most likely candidates.

Not a fit: People without the flu, those who can take existing oral or inhaled antivirals without issue, and individuals with skin conditions or allergies to patch materials may not benefit.

Why it matters

Potential benefit: If successful, the patch could make an effective flu antiviral easier to use for people who cannot inhale medicines and could broaden access during seasonal outbreaks or pandemics.

How similar studies have performed: Microneedle and transdermal patches have shown promise for vaccines and some drugs, but using a zanamivir MAP for flu treatment is relatively novel and not yet widely tested in patients.
