Lansoprazole

Lansoprazole (CAS 103577-45-3, EC 645-308-1) is a proton pump inhibitor active pharmaceutical ingredient known under trade names including Ogast, Lanzor, Lansox, and AG 1749. It carries no assigned E-code and is classified under HS code 29339900 within the pharmaceutical intermediates category.

In pharmaceutical manufacturing, lansoprazole is incorporated into finished dosage forms targeting gastric acid suppression, where it irreversibly binds to the hydrogen-potassium ATPase enzyme in gastric parietal cells to inhibit acid secretion. Research applications also explore its antimicrobial activity, where it disrupts bacterial membrane function, supporting formulation work in anti-infective therapeutic development.

Lansoprazole is supplied as a white crystalline powder meeting Ph.Eur. and ICH quality standards applicable to active pharmaceutical ingredients. Procurement is subject to REACH compliance for European supply chains. Standard packaging formats follow pharmaceutical-grade handling requirements, and documentation including CoA and impurity profiles is available upon request.
