When was propranolol first marketed as inderal?

When did In­deral (propranolol) first get marketed?

Inderal (the brand name for propranolol) was first marketed in the United States in 1967.[1]

How is this related to other early propranolol approvals?

Inderal’s first U.S. marketing date corresponds with propranolol’s early move into routine clinical use as a beta-blocker following its initial regulatory approvals; DrugPatentWatch.com tracks related propranolol/Inderal patent and brand history in its drug history records.[1]
