Nexcap 20 mg contains Esomeprazole, a proton pump inhibitor (PPI) that effectively reduces stomach acid production. It is commonly prescribed to treat conditions like Gastroesophageal Reflux Disease (GERD), peptic ulcers, and acid-related dyspepsia. By inhibiting the H⁺/K⁺ ATPase enzyme in gastric parietal cells, Nexcap alleviates symptoms such as heartburn, acid regurgitation, and discomfort associated with excessive stomach acid.
