Percentage of propranolol prescriptions generic vs brand?

In the United States, propranolol is overwhelmingly generic. Brand-name propranolol prescriptions are a very small share—typically only a few percent or less, with most prescriptions filled as generic propranolol (e.g., propranolol hydrochloride).

Exact percentages vary by year and data source (retail pharmacy vs. Medicare/Part D, country, formulation), and there isn’t a single public figure that covers all cases.

If you want, I can try to pull the most recent country-and-year-specific percentage from a data source (e.g., Medicare Part D data or IQVIA reports). Tell me:
- the country you care about
- the year range
- whether you want general retail or a specific program (e.g., Medicare Part D) data.
