What conditions is esomeprazole suitable for treating? Esomeprazole (Nexium) is approved for 1. Gastroesophageal reflux disease (GERD): treatment of reflux esophagitis and long-term treatment to prevent recurrence in patients with cured esophagitis. 2. Combined with appropriate antibacterial therapy, it can eradicate Helicobacter pylori, heal duodenal ulcers related to Helicobacter pylori infection, and prevent the recurrence of peptic ulcers related to Helicobacter pylori infection. 3.

Esomeprazole was first launched in the UK in 2000. Esomeprazole is esomeprazole, with the trade name Nexiumò (Chinese translation of "Nexium"). Esomeprazole (Nexium) is the world's first isomer proton pump inhibitor (I-PPI) isolated and synthesized by the Swedish company AstraZeneca. Due to its remarkable efficacy and low dosage, since its introduction in 2000, it has set an astonishing record of global sales exceeding US$1 billion.

Esomeprazole (Nexium) is a new type of anti-peptic ulcer drug and proton pump inhibitor. It is also the world's first proton pump inhibitor (PPI) used clinically. It has been approved in 65 countries for the treatment of various gastric acid-related diseases.

H+-K+-ATPase (proton pump) exists in gastric parietal cells and is the final link in gastric acid secretion. PPIs are "prodrugs" that are first converted into sulfenic acid and sulfinamide (activated compounds) in gastric parietal cells, and then combine with H+-K+-ATPase to inactivate the enzyme, thereby inhibiting gastric acid secretion and reducing pepsin secretion. Esomeprazole is the levorotatory isomer of omeprazole. It is metabolized by CYP3A4 and CYP2C19 and has a stronger acid-suppressing effect than other PPIs.
