PARIET 20MG Tablet is a proton pump inhibitor (PPI) that effectively reduces stomach acid production, providing relief from conditions like acid reflux, heartburn, and gastroesophageal reflux disease (GERD). Its active ingredient, rabeprazole, works by blocking the enzyme in the stomach wall that produces acid, promoting healing of erosive esophagitis and preventing ulcers. PARIET is known for its rapid onset of action and long-lasting effects, making it a preferred choice for patients with chronic acid-related disorders.
