Telmisartan

Telmisartan (CAS 144701-48-4), marketed under the brand names Micardis and Pritor, is an angiotensin II receptor antagonist used as an active pharmaceutical ingredient in antihypertensive drug formulations.

As a selective AT1 receptor blocker, it is sourced by pharmaceutical manufacturers and API importers for finished dosage form production. The primary application is in the manufacture of oral solid dosage forms.

These include tablets and capsules targeting cardiovascular indications such as hypertension and cardiovascular risk reduction. Contract manufacturers and generic drug producers source this key API when developing bioequivalent formulations.

In pharmaceutical R&D, it is used in combination product development alongside diuretics such as hydrochlorothiazide. Cosmetic researchers have also investigated it in topical formulations for antioxidant and stabilizing activity.

The material is supplied as a white to off-white crystalline powder in quantities ranging from research-scale grams to commercial kilogram and metric-ton lots. It is available in pharmaceutical-grade specifications.

The product conforms to USP, BP, and Ph. Eur. monographs, supporting regulated market submissions. Certificate of Analysis, impurity profiles, and DMF support documentation are standard requirements for buyers.
