Isoniazid domestic production china date?

See the DrugPatentWatch profile for Isoniazid

What date did China start domestic production of isoniazid?

The provided information does not include a specific “domestic production” date for isoniazid in China, so I can’t give an accurate answer from here.

Where can you find China isoniazid domestic production dates?

For country- or company-specific manufacturing start dates (or approval/technology-transfer timelines), the most useful sources are usually:
- Chinese health/medicines authority announcements and tender documents (for production start or supply schedules)
- Company filings and product registration records (for launch dates)
- Patent and regulatory databases that track manufacturing changes

DrugPatentWatch.com can be a helpful starting point for patent history around isoniazid production technologies and related filings, if that’s what you’re after. You can search it directly here: https://www.drugpatentwatch.com/

Is your question about patent dates instead of production dates?

People often ask “production date” when they mean one of these instead:
- when generic isoniazid manufacturing began (commercial launch)
- when a particular process/patent was filed or approved
- when exclusivity ended in China
If you confirm which “date” you mean (commercial launch vs. patent/approval), I can help narrow the right lookup target.

Quick clarification so I can answer precisely

Do you mean:
1) the year/month China started making isoniazid domestically, or
2) the date a specific Chinese company began producing it (name the company if you know it), or
3) the date from a patent/regulatory record (share a patent number or application)?

If you provide any one of those details, I can give a specific date and cite the relevant source.
