Drug delivery microchip implanted in patients, passes human trial

A remote drug delivery system has successfully been tested in a human trial. A microchip was implanted in 8 women and delivered a drug to treat osteoporosis once a day for 20 days. There were no adverse affects and, compared to a control group of women who injected the drug, the microchip-delivered treatment was just as effective.

The miniature chip, 5 cm long and 3 cm wide, was implanted under local anesthesia in just 30 minutes. It contained 20 tiny reservoirs, each of which holds 600-nanoliters of drug solution, over which a thin layer of platinum or titanium contained the drug. Upon dosing, a current is applied which melted the metal coverings and allowed for drug release. The chip’s actions can be programmed for drug release at specific intervals or on demand with the use of wireless communication link. The bidirectional communication also tells researchers whether the chip is working properly or not.
