都市人不可不知的胃藥 Something You Should Know About ‘Stomach Medicine’
現今社會生活節奏快且工作壓力大，許多都市人都有胃部毛病，例如胃痛、胃灼熱及胃酸倒流等症狀。但市面上的胃藥五花八門，如何選擇適合自己的藥物？今天為大家簡單介紹常見的胃藥吧！
Hong Kong is a fast-paced city and everyone is living under pressure. Stomach problems such as stomach pain, heartburn and acid reflux are common. There are many different medications for stomach problems in the market. How can we choose the most suitable one for ourselves? Let’s learn more about different types of stomach medicines!
制酸劑 Antacid
這類藥物的藥理是提高酸鹼度，以減少胃酸的刺激，達致即時中和胃酸之效。其中含鎂的制酸劑有機會引致腹瀉，而含鋁的則有機會引致便秘，所以市面的產品多為鎂鋁混合配方以減少副作用。
Antacid increases the pH in the stomach and decreases the irritation to the stomach and neutralizes stomach acid immediately. Magnesium, one of the ingredients, may increase the risk of diarrhea while aluminium may increase risk of constipation. Therefore, most of the products contain both ingredients to counteract the side effects of each other.
組織胺受體阻斷劑 H2-Receptor Antagonist
這類藥物透過抑制胃部的組織胺，以減少大約70% 的胃酸分泌。除了能舒緩因胃酸引起的不適如胃灼熱或倒流外，也可針對因胃酸過多而導致的胃潰瘍。
H2-Receptor Antagonist inhibits the histamine receptors in the stomach and suppresses approximately 70% of the acid. It does not only relief the stomach upset caused by heartburn or acid reflux but can also be used for gastric ulcers caused by excessive stomach acid.
質子泵抑制劑 Proton-Pump Inhibitor
藥理跟組織胺阻斷劑類似但藥效更強，能抑制100% 的胃酸。通常當其他藥物失效時才會考慮此藥物，而市面上所有此類產品都需要藥劑師的監督下銷售或醫生處方。若非醫生指示，不會長期服用。
Its mechanism of action is similar to H2-Receptor Antagonist but stronger, suppressing 100% of the acid.PPI is considered when other medications failed. All PPIs are only sold under supervision of a pharmacist or prescription from doctor. Unless advised by doctor, it should not be taken long term.
