NOXA20胃黏膜保护：NSAID安全联用指南

　　NOXA20含NSAID类吡罗昔康，对胃有刺激。必要时可联用胃黏膜保护剂，安全用药。

▲胃黏膜保护药物

　　【NSAID伤胃机制】NSAID抑制环氧合酶，减少前列腺素合成。前列腺素保护胃黏膜。长期使用导致胃黏膜损伤、溃疡、出血。

　　　　【高危人群】有胃溃疡史、幽门螺杆菌感染、高龄、联用阿司匹林/激素者，胃损伤风险更高。

　　【胃黏膜保护方案】PPI质子泵抑制剂（奥美拉唑、雷贝拉唑）是首选。饭后服用NOXA20可减轻刺激。

　　　　【安全用药原则】NOXA20短期使用（3-5天），不长期连续。饭后服用。不与其他NSAID合用。

　　【警示症状】黑便、呕血、严重胃痛、食欲下降、体重下降，应立即停药就医。

　　　　【替代方案】对胃敏感者，医生可能选择对胃刺激小的NSAID（如塞来昔布）或秋水仙碱。

　　【NOXA20使用建议】急性发作短期使用，症状缓解即停。不要为了预防而长期服用。

English Translation

NOXA20 contains Piroxicam, an NSAID that irritates the stomach. When needed, combine with gastroprotective agents for safe use.

How NSAIDs hurt the stomach: NSAIDs inhibit cyclooxygenase, reducing prostaglandin synthesis. Prostaglandins protect the gastric mucosa. Long-term use causes mucosal damage, ulcers, and bleeding.

High-risk groups: Those with gastric ulcer history, H. pylori infection, elderly, or taking aspirin/steroids have higher gastric damage risk.

Gastric protection: PPI proton pump inhibitors (omeprazole, rabeprazole) are first-line. Taking NOXA20 after meals reduces irritation.

Safe use principles: Use NOXA20 short-term (3-5 days), not long-term continuously. Take after meals. Do not combine with other NSAIDs.

Warning symptoms: Black stools, hematemesis, severe stomach pain, loss of appetite, weight loss require immediate discontinuation and medical care.

Alternatives: For stomach-sensitive individuals, doctors may choose stomach-sparing NSAIDs (like celecoxib) or colchicine.

NOXA20 recommendation: Use short-term during acute attacks, stop when symptoms subside. Do not take long-term for prevention.
