The team from the Massachusetts Institute of Technology (MIT) first embarked on a clinical trial in Denmark last year, implanting chips loaded with 20 doses of teriparatide into the bodies of seven female osteoporosis sufferers aged 65 to 70.
They found the chips were able to supply more consistent results than when teriparatide is injected into the body.
Doses from the chips are delivered using a small electrical current that melts the thin layer of platinum and titanium covering the reservoirs holding the drug.
According to the scientists behind the study, this advance could benefit patients suffering from a wide range of conditions.
"Patients with chronic diseases, regular pain-management needs or other conditions that require frequent or daily injections could benefit from this technology," said Robert Farra, president and chief operating officer at MicroCHIPS and lead author of the paper.
In the future, it is hoped that the chip technology can be combined with sensors to provide a reactive solution to drug administration.
