Mechanism of Action of undefined

Omeprazole, Tinidazole, and Amoxicillin are used to treat stomach and intestinal ulcers caused by bacterial infections. Omeprazole is a proton pump inhibitor (PPI) that reduces stomach acid, helping to treat acid-related indigestion and ulcers. 

Tinidazole is an antibiotic that kills bacteria and other microorganisms by damaging their DNA. Amoxicillin is another antibiotic that prevents the formation of the bacterial protective covering, which is essential for bacterial survival. Together, they effectively eliminate the infection.
