Pantex
Pantoprazole
Description
Pantex® is a preparation of Pantoprazole. It is a substituted benzimidazole derivative that
suppresses the proton pump, final step of gastric acid secretion, by forming a covalent bond
to two sites of H+-K+ ATPase enzyme. This leads to inhibition of both basal and stimulated
gastric acid secretion irrespective to the stimulus. The binding of Pantex® to the H+-K+
ATPase results antisecretory effect which persist longer than 24 hours.

adjustment is needed with concomitant use of the following drugs; theophylline,
antipyrine, caffeine, carbamazepine, diazepam, diclofenac, digoxin, ethanol, glyburide, oral
contraceptive (levonorgestrel or ethynyl estradiol), metoprolol, nifedipine, phenytoin, or
