A paper based testing kit that can spot counterfeit drugs is being developed by US researchers. The test uses a set of simple colour-changing tests on a credit-card sized paper sheet to detect fake Panadol (paracetamol) tablets and kits are being developed to detect fake antimalarials, antibiotics and other drugs. The cheap and simple devices could be used in developing countries, where price pressures and poor regulation combine to make counterfeit drugs a major problem.
