About Omeprazole
Omeprazole is one of the most commonly used medications in Nigeria, widely known as "the ulcer drug." Walk into virtually any pharmacy or patent medicine store across the country — from Ikeja to Kano, Enugu to Port Harcourt — and you will find omeprazole on the shelf. It belongs to a class of drugs called proton pump inhibitors (PPIs), which work by reducing the amount of acid produced in the stomach. This makes it highly effective for treating peptic ulcers, acid reflux, and other conditions caused by excess stomach acid. In Nigeria, where the prevalence of peptic ulcer disease is high, omeprazole has become a household name.
