Inderal developed by ici pharmaceuticals?

Who developed Inderal (inderal) and what was ICI Pharmaceuticals’ role?

Inderal (propranolol) was developed as a beta-blocker drug by ICI Pharmaceuticals (Imperial Chemical Industries). Inderal later became widely marketed under that name, with ICI Pharmaceuticals also associated with its development and early commercialization [1].

What company marketed Inderal after ICI?

After ICI, propranolol products and the Inderal brand moved through industry ownership changes and licensing over time, as is common with older, off-patent medicines. The exact brand-holder can vary by country and time period, but ICI is the key developer historically tied to Inderal’s origin [1].

Why does the “developer” question come up for older drugs like Inderal?

For older drugs, multiple companies may appear in records: one company may have developed the molecule or initial formulation, while others later marketed it, acquired rights, or filed follow-on paperwork. That makes “developed by” (origin) different from “currently marketed by” (present-day).
