Which companies make losartan potassium API?
Losartan potassium active pharmaceutical ingredient (API) is produced by multiple generic-API manufacturers worldwide. The exact set of suppliers depends on the grade (e.g., USP/EP), intended market (US/EU/ROW), and whether you mean the finished API form or specific intermediates used to make it.
How to find a verified losartan potassium API supplier (without guesswork)
If you are trying to source or qualify a losartan potassium API supplier, you typically need one or more of the following:
- Evidence the company supplies a specific regulatory grade (USP/EP) or has documentation you can audit.
- Batch/CoA support and quality agreements.
- Manufacturing site details and regulatory inspection history (where available).

Is losartan potassium API made in-house or by contract manufacturers?
In many markets, the API brand you see (or buy) is often manufactured by:
- Dedicated API manufacturers, then sold to branded/generic drug makers, or
- Contract manufacturing organizations (CMOs) that produce the API under agreements with pharma manufacturers.
To identify the exact maker for a specific “API company” claim, you usually need the supplier’s listing, the drug’s finished product application/filing package references, or direct documentation from the supplier.
