USP/EP-grade Esomeprazole Magnesium Trihydrate (CAS 217087-09-7) supplied wholesale by Zyntex to licensed producers. Proton pump inhibitor API for delayed-release capsules, tablets and sachets. CoA and SDS with every lot.
Esomeprazole magnesium trihydrate is a white to slightly colored crystalline powder that is slightly soluble in water. As the single S-isomer of Omeprazole, it gives more consistent acid suppression. Like other proton pump inhibitors, it is destroyed by stomach acid, so it is formulated as enteric-coated pellets.
In addition, pharmaceutical companies use it in 20 mg and 40 mg delayed-release capsules and tablets (often as multiple-unit pellet systems) and in granules for oral suspension for reflux disease, ulcers and Helicobacter pylori regimens. Many of these products are also sold over the counter. Related acid-reducing APIs in our range include Pantoprazole and Famotidine.
Notably, Zyntex supplies esomeprazole magnesium from qualified API producers, only to licensed pharmaceutical companies.
