Call it medicine on a microchip.Researchers in the United Stateshave developed the first wirelessly controlled devicethat can supply a drug directly into the body.A small chip is implanted under the skin.It contains the medicine,which it releases at preset times.The developers say the device could improvethe lives of millions of peoplewho take medicine for long-term illnesses.A company called MicroCHIPS begandeveloping the device about fifteen years ago.Last month, the company released the resultsof its first successful tests in humans.The tests took place in Denmarkwith seven women with osteoporosis.Osteoporosis causes bones to become weak and break easily.The disorder is common among older people, especially women.Many patients have to give themselves daily injections of medicine.One type of treatment requires injections for two years.Robert Farra is the president of MicroCHIPS.He says many patients stop taking the medicinebecause of the pain and stress of the injections.ROBERT FARRA: "And, as a result,only twenty-five percent of the patientswill go through the entire twenty-four months of treatment."The microchip is a few centimeters long.It has small sections that each hold a single dose of medicine.Mr. Farra says the device has to be programmedwith the times to release the drug.ROBERT FARRA: "For osteoporosis,the physician will program the device,and the device has the ability to release a dose at a given time, every single day. For other diseases,where the physician may want to alter the dosing schedule,they will have the abilityto wirelessly reprogram that dosing schedule."He says doctors will be able to reprogram the devicefrom a computer or even a cell phone.The seven women in the study were ages sixty-five to seventy.The researchers say the implants were justas effective as daily injections.And they say the dosage amountswere more exact than patients often give themselves.The microchips in the study held only twenty doses of medicine.Mr. Farra and his team are now designing a versionthat could hold a full year's worth of medicine.ROBERT FARRA: "We anticipate two years to complete the design,and then we may be required to do two additional trials,taking us out to a total of four yearsbefore the device is available on the commercial scale."He says the microchips may one day free patientsfrom having to remember to take their medicine,or give themselves injections.He says the device may also be usefulin treating other chronic diseases,including heart disease and multiple sclerosis.And that's the VOA Special English Technology Report,written by June Simms.
