Have you been suffering from gastritis for a long time with stomach pain and inflammation? Has your doctor examined you and told you that your stomach ulcers are caused by a bacteria called H. pylori? If so, and you were given a pack of three medications at once, this article will be very important to you. Let's talk briefly about what these medications are, how they work, and what you need to be careful about when taking them.
What is Triple Therapy?
Simply put, it's a combination of three medications. It's like a special operation team. The three main members of this team are Lansoprazole , Amoxicillin , and Clarithromycin . Together, these three work to fight the bacteria called H. pylori in your stomach.
Think of H. pylori as a rogue bacteria that hides in the walls of your stomach and causes problems.
1. Lansoprazole: This works by reducing the amount of acid produced in your stomach. This acid is a safe haven for the H. pylori bacteria. So Lansoprazole weakens that acid shield, paving the way for the other two drugs to attack the bacteria. We call these types of drugs proton pump inhibitors (PPIs).
2. Amoxicillin and Clarithromycin: These two are the main fighters. These are two types of antibiotics. They attack the H. pylori bacteria directly and kill them, or stop their growth. Amoxicillin is a penicillin antibiotic, while Clarithromycin is a macrolide antibiotic.
Only when these three medications work together can the H. pylori bacteria be completely eliminated from your body and stomach ulcers can be healed.
Things you need to tell your doctor before starting medication
Before starting this treatment, it is extremely important to inform your doctor if you have any of the following conditions:
| Your health condition | Things to pay special attention to |
