I would guess the majority of Pharmaceuticals are still manufactured here in the United States.
Europe is insane with regulation and taxes, who would want to do the actual manufacturing of drugs or anything there.
FDA regulations for clinical trials made it so expensive to run trials that Pharma migrated the trials to Europe 20+ years ago. We used to get the cutting edge medicines but now only after Europe runs the trials and approves them. The FDA will then use the European data to review and decide on approval for the US.

While some pharmaceuticals are manufactured in the United States, a significant portion of those used in America are produced overseas, particularly in China and India. The United States is a major player in pharmaceutical manufacturing, but its share of global production has decreased over time.
Here's a more detailed look:
United States:
The U.S. is a major producer of pharmaceuticals, accounting for a significant portion of active pharmaceutical ingredients (APIs) used in medicines consumed in the country.
China:
China has emerged as a major global player in the pharmaceutical industry, especially in the production of APIs and generic drugs.
India:
India is another significant producer of pharmaceuticals, particularly generics, and is a major supplier of APIs to the U.S. market.
Other Countries:
Europe, Canada, Japan, and other nations also contribute to the production of pharmaceuticals for the U.S. market, according to PharmacyChecker.
