Biological target: Omeprazole sodium (H 16868 sodium) is a proton pump inhibitor (PPI).
In vitro activity: The antibacterial effects of omeprazole (100, 200 and 300 mg/L) were assessed using bacterial growth curves. A dose-related permanent inhibition was seen with actively growing Gram-positive cocci. A reduced and only temporary effect was observed with Gram-negative bacilli. After 1 day the bacterial count of Helicobacter pylori in the presence of omeprazole 200 mg/L was reduced from 10(4) cfu/mL for the control to zero. Reference: J Antimicrob Chemother. 1996 Jan;37(1):145-50. https://pubmed.ncbi.nlm.nih.gov/8647756/
In vivo activity: This study revisited the effect of omeprazole treatment on the degree of anxiety-like behaviours in a cysteamine hydrochloride (HCl) induced mouse model of GI disorder using open field test (OFT), light-dark box (LDB) test and elevated plus maze (EPM). Results revealed that omeprazole treatment mitigates anxiety-related behaviours in the cysteamine HCl induced animal model of GI disorder. Thus, this study assuredly supports and validates the anxiolytic properties of omeprazole. Reference: Heliyon. 2022 Jun 24;8(6):e09787. https://pubmed.ncbi.nlm.nih.gov/35800723/
