What to know about Pharmaceutical Engineering

Researchers at Cornell University have developed a nanofiber film made from cyclodextrin that can deliver a combination of three pain-relief drugs in under two seconds. The study, published in the International Journal of Pharmaceutics, suggests this method is more efficient than powder or tablet forms and uses a water-based manufacturing process.

What happened

Breath-strip-like nanofiber film delivers three pain drugs in under two seconds Gaby Clark Scientific Editor Robert Egan Senior Editor Children and seniors who have difficulty chewing and swallowing conventional tablets may have an easier way to find pain…

Why it matters

Cornell researchers have developed an ultrafast-dissolving nanofiber film that can deliver a cocktail of three drugs so quickly and effectively that 90% of the formulation is released in less than two seconds.

Common ground

The findings were reported in the International Journal of Pharmaceutics.

Claim 3: “the subsequent film, which resembles a breath strip, is the first nanofiber system that can release a triple-drug combination.”
SINGLE SOURCE
The claim that this is the 'first' nanofiber system to release a triple-drug combination is a specific superlative. While the research is corroborated, the 'first ever' status is not independently verified by multiple sources in the provided evidence.

Claim 4: “nanofibers, which are 1,000 times smaller than a single human hair”
VERIFIED BY REFERENCE
Wikipedia defines nanofibers as having diameters in the nanometer range (1 nm to 1 μm). A human hair is typically 50-100 μm, making nanofibers approximately 1,000 times smaller in diameter.
