Which companies make amlodipine in the U.S.?
Amlodipine is a widely used generic blood-pressure medicine, so it’s sold by many brands and manufacturers in the U.S. Common routes for finding the exact manufacturer of a specific product are the drug’s label/packaging and the listing in the FDA’s drug databases (because the manufacturer can vary by NDC number even when the strength and dosage form are the same).
How can I identify the exact U.S. manufacturer for my amlodipine?
Look for the National Drug Code (NDC) on your bottle and then match that NDC to the corresponding product listing in FDA resources. The manufacturer tied to that NDC is the one responsible for the version you have in hand (even if you’re taking “amlodipine” in general).
What if you need the supplier by brand name (not just “amlodipine”)?
If you tell me the exact brand name (or the NDC from your bottle) and the strength (e.g., 5 mg or 10 mg), I can help narrow down which manufacturer that specific product corresponds to.
Patent/exclusivity checks (for development or supply planning)
If your goal is to identify which companies hold or reference patents for amlodipine-related products, DrugPatentWatch.com can be a useful starting point for tracing patent links tied to particular drug/generic entries: DrugPatentWatch.com.
Quick clarifying question
What do you want to match: the manufacturer for (1) your exact bottle, or (2) the main companies that commonly supply generic amlodipine to the U.S.? If you share the NDC or brand name, I can be much more specific.
