(Medical Xpress) -- A new pharmaceutical program that many Britons might find literally hard to swallow, has been announced. Pharmacy chain Lloydspharmacy has partnered with American technology firm Proteus Biomedical to bring to the British public a product called Helius; a tiny microchip that is swallowed in pill form and whose purpose is to help remind patients to take their medications on time and to offer bio-feedback such as body temperature, heart rate and even sleeping patterns.
