Questions about Resonance Laboratories

Does Resonance Laboratories hold a US DMF or a CEP?
Resonance Laboratories holds 8 active US drug master files and 1 valid CEP. A drug master file is a submission to the FDA describing how an ingredient is made; a CEP is the EDQM's certificate that the substance meets its European Pharmacopoeia monograph. Both are filings rather than approvals.
Is Resonance Laboratories FDA-registered?
One site operated by Resonance Laboratories carries an FDA establishment identifier (FEI), which means it is registered with the FDA as a drug establishment. Registration is not the same as approval or inspection clearance.
How did Resonance Laboratories's last inspection go?
The most recent inspection on record closed on 7 February 2025 as VAI (Voluntary Action Indicated: issues were found but did not warrant regulatory action). 2 inspections are on file, of which 1 closed as OAI.
Where does Resonance Laboratories manufacture?
1 registered site is on record, in India (Bengaluru). Every site is listed on this page with the register it came from.
What does Resonance Laboratories make?
4 molecules are on record against Resonance Laboratories, including Atropine, Clidinium, Glycopyrronium and Oxybutynin. Each links through to that molecule's full manufacturer list.
Which regulators recognise Resonance Laboratories's GMP?
Current GMP certificates are on record from US FDA and EMA. GMP recognition covers the manufacturing site, separately from any filing on the substance itself.
