Simply as a enterprise wants an efficient and dependable service to ship its items to clients, drugs want an efficient supply system to get them to the precise space of the physique the place they’ll have an effect.
The College of Cincinnati’s Daniel Solar, MD, has acquired a profession growth award of simply greater than $1 million from the Nationwide Institutes of Well being’s Nationwide Institute on Deafness and Different Communication Problems to analysis the potential of utilizing magnetic nanoparticles as a supply system for medication to succeed in the inside ear and deal with listening to loss.
Apart from typically ineffective steroids, there are presently no medication authorized by the Meals and Drug Administration to deal with listening to loss, and getting the drugs into the inside ear, the place listening to loss happens, is a serious hurdle.
“There are a whole lot of attention-grabbing drugs which can be within the pipeline which have a whole lot of potential to rework the way in which we deal with listening to loss and permit us to delay and even reverse listening to loss,” stated Solar, the Myles L. Pensak, MD, Endowed Professor in Neurotology and Cranium Base Surgical procedure, director of the Division of Neurotology, neurotology fellowship program director and affiliate professor of otolaryngology within the College of Cincinnati Faculty of Drugs, and a UC Well being doctor. “However we do not have a great way to get these promising drugs into the ear very successfully.”
Magnetic nanoparticles have been used as a drug supply system in different elements of the physique, however Solar stated his analysis helps develop a greater understanding of precisely how one can engineer the nanoparticles particularly for the ear’s anatomy.
The purpose is to create one thing that is minimally invasive after which use a magnetic area to steer these nanoparticles into the ear the place listening to loss is going on.”

Completely different sorts of listening to loss, like age-related listening to loss, noise trauma and sudden listening to loss, are brought on by totally different mechanisms and due to this fact handled by totally different drugs. If magnetic nanoparticles are efficient, they might act because the supply truck that will get loaded up with the precise remedy every affected person wants primarily based on their form of listening to loss.
“Based mostly on the way in which they’re engineered, these particles can carry many various types of drugs,” Solar stated. “It is important that we will use a standard platform for various drugs that may goal several types of listening to loss.”
Along with the magnetic area analysis, Solar and Donglu Shi, PhD, from UC’s Division of Mechanical and Supplies Engineering, are collaborating to check the effectiveness of lasers to activate the nanoparticles and assist them penetrate the inside ear.
“We wish to method it very systematically and rigorously to really perceive how one can design these nanoparticles in a means that’s biocompatible, that’s secure for listening to and steadiness perform within the ear,” Solar stated. “On the similar time, we wish to present very strong drug supply capabilities. We’re actually ranging from the bottom as much as perceive how these particles actually penetrate the membrane that separates our center ear from the inside ear and the way these particles truly go to the areas of the inside ear that we’d like them to go to.”
Long run, Solar stated a breakthrough in drug supply mixed with the brand new drugs being developed may open a brand new world for noninvasive therapy of listening to loss.
“We actually wish to look to a future the place folks, no matter age or their well being, can safely bear these remedies with these promising drugs in a means that’s minimally invasive and in addition efficient in treating their listening to loss,” he stated.
Solar was initially awarded this grant whereas at Johns Hopkins College and transferred the grant when he joined the college at UC.
