From what I have heard from people who work in pharma companies in India, the main reasons drugs are cheaper when manufactured in India are: - not much R&D costs to design new drugs (however they do spend on designing the manufacturing process) - cheap labor for manufacturing, including a good supply of chemical engineers. - environmental regulations for chemical manufacturing are stricter in Western countries.
