India's National Pharmaceutical Pricing Authority placed pricing controls on frequently used antibiotics including Ciprofloxacin, diabetic drugs including Metformin, and heart medications. It also said it would audit manufacturers to ensure that normal production continues. The pricing authority acts under a 1955 law that requires pricing to be affordable for essential drugs needed by the vast majority of poor people in the country. Some mass consumption drugs are now imported where it is unprofitable to make them in India. In the case of other drugs the volume increases from lower prices increases access to medicines, and the volume makes up for the price cuts. An example cited by the pricing authority is essental antibiotic (especially for children), Augmentin, where the prices dropped by 40% but the volume increases as it became more affordable have more than made up for the price reductions, with overall sales higher than before the price cuts.
