API

Active Pharmaceutical Ingredients are gotten from both China and India because they are cheaper in price. Keeping the cost of US medications down.
That will start to change as shown when the COVID-19 locked down both travel and supply chains. Still any company that needs these small molecule drugs will find that both of these countries can make them cheaper and in large quantities.The other problem is still cost of making them here.
Even that major companies are already invested billions of dollars in manufacturing plants in the US, billions would still be needed for more plants.
Which will reflect upon the cost of drugs.
Which the US consumer may not want to pay for.
