What is Omefast-20?
Omefast-20 is a proton-pump inhibitor (PPI), with Omeprazole 20mg per capsule (enteric-coated pellets) manufactured by Greenlife Pharmaceuticals (imported) and listed under NAFDAC. It works by irreversibly inhibiting the H⁺/K⁺ ATPase enzyme (“acid pump”) on stomach parietal cells, which suppresses gastric acid secretion.
