Microneedles improve drug delivery

Recently New Zealand member Matt drew BUS’s attention to  research into the use of micro needle technology for the delivery of therapeutic drugs to the back of the eye . This link that takes you to the article found in “Gizmag”.

This procedure has yet to be trialled on humans, but if it works as it does in the animal study, it  could well open the door for better treatment via eye injections.   It should provide a less invasive and more targeted way of getting injections into the eye, and will open the way for slow-release drug design. Of particular note,  the injected molecules did not reach the lens or front part of the eye in significant amounts decreasing the chances of side effects such as cataracts which commonly occur with this type of treatment.

Details of the study were published in the July 2012 issue of the “Journal Investigative Ophthalmology and Visual Science” where you can read the abstract for free, but you need to pay or be a member to access the full paper.
