When did propranolol become generic?

Propranolol became generic in the United States in the mid-1980s. After the original patent expired, multiple manufacturers started selling propranolol hydrochloride tablets as generics, so by the late 1980s it was widely available as a generic product.

Notes:
- Exact timing varies by country and by specific product/formulation.
- If you need the precise year for a particular country or salt (e.g., propranolol hydrochloride tablets vs. extended-release forms), I can help outline how to check (e.g., FDA Orange Book in the U.S. or equivalent patent/approval databases in other countries).
