What patent and source dates apply to gentamicin (1962 approval; 1964 marketed)?
Your question mixes two different kinds of dates that often get confused for medicines: the patent filing/publication date and the approval/authorization date. With only “1962 approved 1964 source” provided, there isn’t enough information to pinpoint a specific gentamicin patent record (or which country/assignee) versus the first marketing/authorization date.
Where can I find the exact gentamicin patent record from those years?
To identify the correct “1962” patent and “1964” drug approval/launch source, you typically need at least one of the following:
- the patent holder or assignee (company or institution)
- the country or patent office (for example, US, EP, UK, etc.)
- whether you mean “gentamicin” broadly (the drug substance) or a specific formulation/process
Once you share that, I can map the two dates to the correct patent document and the corresponding approval/marketing source.
Can you confirm which gentamicin “approval” you mean (drug authorization vs first clinical use)?
“Approved” can refer to different events:
- regulatory marketing authorization (formal approval)
- national registration that enables sale
- first publication/availability (sometimes treated as “approval” in secondary sources)
If you tell me the jurisdiction (e.g., US FDA, UK, etc.) I can align “1962” and “1964” correctly.
What I need from you to answer with a precise citation
Reply with any one of these, and I’ll produce the exact patent citation(s) and the approval/source citation(s):
- a link or screenshot of the place where you saw “1962” and “1964”
- the patent number (or at least the country + assignee)
- the regulator/jurisdiction tied to “1962 approved”
Sources: none cited (the provided prompt does not include verifiable documents or enough identifying details to link to an authoritative patent/approval record).
