Omeprazole 是有效的质子泵抑制剂，在胃肠道疾病的研究中具有价值。它竞争性抑制CYP2C19活性，Ki为 2 到 6 μM。它还抑制革兰氏阴性菌和革兰氏阳性菌生长。它是中性鞘磷脂酶的外泌体抑制剂。

Omeprazole Sodium is a proton pump inhibitor(PPI) and suppresses gastric acid secretion. Omeprazole Sodium is a potent neutral sphingomyelinase (N-SMase) inhibitor (exosome inhibitor). Omeprazole Sodium shows competitive inhibition of CYP2C19 activity with a Ki of 2 to 6 μM. Omeprazole Sodium inhibits growth of Gram-positive and Gram-negative bacteria.

Omeprazole Sodium virtually eliminated intragastric acidity in all patients: the median 24 hour intragastric pH rose from 1.4 to 5.3 and the mean hourly hydrogen ion activity fell from 38.50 to 1.95 mmol(mEq)/1 (p less than 0.001)[1]
