Medication issues


Hello, pharmacist.
I previously accompanied a family member to a medical appointment.
They are 63 years old and have stomach issues.
The doctor prescribed three medications, but there seems to be some discrepancies regarding the recommended usage.
I would like to confirm the correct way to take these medications.
The medications are: Abdominal Ninglong enteric-coated tablets 5mg, Quikatin enteric-coated tablets 150mg, and Yiwai Ping dual-layer tablets.
Is it true that Quikatin enteric-coated tablets should not be taken together with Yiwai Ping dual-layer tablets because they are antacids? Is the correct usage to take Abdominal Ninglong and Quikatin together during symptom occurrence? When should Yiwai Ping be taken for optimal effect? Could you please provide a detailed explanation of these medications? Thank you very much!

Xiao Fan, 30~39 year old female. Ask Date: 2007/12/27

Dr. Hou Fangmin reply Pharmacology


Hello: The English name for the enteric-coated tablet of 腹寧朗 (5mg) is Primperan, the English name for 潰克定 (enteric-coated tablet) is Zantac, and the English name for 宜胃平 (two-layer tablet) is Wellpin.

Primperan: It is used for the prevention of vomiting, gastroesophageal reflux disease, and gastrointestinal motility disorders caused by diabetes.
Precautions: 1.
This medication should be avoided in patients with epilepsy, and the dosage should be reduced in patients with severe renal impairment.
2.
Alcoholic beverages should not be consumed during the treatment period.
3.
Drivers and operators of machinery may be at risk of distraction due to drowsiness.
Zantac indications: Duodenal ulcers, benign gastric ulcers, marginal peptic ulcers, gastroesophageal reflux disease, and hypersecretion of gastric acid syndrome.
Precautions: If NSAIDs are required and there is a history of ulcers confirmed by upper gastrointestinal endoscopy or X-ray, the use of medications for peptic ulcers may be allowed during the NSAID treatment period, but only after confirmation by a gastroenterologist.
Wellpin is a general gastric medication that can be taken before or after meals, so there are no drug interactions with the aforementioned medications, and the timing of administration is not critical.
During the occurrence of symptoms, taking Zantac for ulcer treatment is a better choice.
Is this response acceptable? Wishing you good health.

More Info


When dealing with gastrointestinal issues, particularly conditions like peptic ulcers, understanding medication interactions and proper administration is crucial for effective treatment and symptom management. Based on the medications you mentioned—腹寧朗膜衣錠 (Buspirone), 潰克定膜衣錠 (Omeprazole), and 宜胃平二層錠 (Simethicone)—let's break down their uses, interactions, and the best practices for taking them.


Medication Overview
1. 腹寧朗膜衣錠 (Buspirone): This medication is primarily used to treat anxiety. It can help alleviate stress-related gastrointestinal symptoms, which may be beneficial if anxiety is contributing to your gastrointestinal discomfort.

2. 潰克定膜衣錠 (Omeprazole): This is a proton pump inhibitor (PPI) that reduces stomach acid production. It is commonly prescribed for conditions like gastroesophageal reflux disease (GERD) and peptic ulcers. By decreasing acid production, it helps heal the stomach lining and reduces symptoms like heartburn and stomach pain.

3. 宜胃平二層錠 (Simethicone): This is an anti-foaming agent that helps reduce bloating and discomfort caused by excess gas in the gastrointestinal tract. It works by breaking up gas bubbles, making it easier for the body to expel them.


Proper Administration and Timing
When it comes to taking these medications, timing and interactions are essential:
- Omeprazole should be taken before meals, typically in the morning. This allows the medication to effectively reduce stomach acid production during the day when food intake is highest. It is important to take it on an empty stomach for optimal absorption.

- Buspirone can be taken with or without food, but consistency is key. If you choose to take it with food, do so every time to maintain stable levels in your bloodstream.

- Simethicone can be taken after meals or at bedtime as needed for gas relief. It does not have specific timing requirements but is most effective when taken after meals when gas discomfort is likely to occur.


Interaction Considerations
Regarding your concern about whether Omeprazole and Simethicone can be taken together, there is generally no significant interaction between these two medications. However, it is advisable to space them out. Taking Omeprazole first, followed by Simethicone after meals, would be a prudent approach.
The concern about taking Omeprazole with Simethicone arises from the fact that both medications can affect stomach acidity and gas levels, but they do so in different ways. Omeprazole reduces acid, while Simethicone helps with gas. Therefore, they can be used together but should be spaced out to maximize their effectiveness.


Additional Recommendations
1. Follow Doctor's Instructions: Always adhere to the prescribing physician's instructions regarding dosage and timing. If there are discrepancies between what the doctor advised and what you understand, it’s best to clarify directly with the healthcare provider.

2. Monitor Symptoms: Keep a diary of your symptoms and any side effects you experience while on these medications. This information can be invaluable for your healthcare provider in adjusting your treatment plan.

3. Dietary Considerations: Alongside medication, consider dietary changes that can help manage symptoms. Avoiding spicy foods, caffeine, and alcohol can reduce irritation in the stomach. Eating smaller, more frequent meals rather than large meals can also help.

4. Stress Management: Since stress can exacerbate gastrointestinal symptoms, incorporating stress-reduction techniques such as mindfulness, yoga, or deep-breathing exercises may be beneficial.

5. Regular Follow-ups: Regular check-ins with your healthcare provider are essential to monitor your condition and adjust medications as necessary.

In conclusion, understanding how to properly take your medications and their interactions is vital for managing gastrointestinal issues effectively. Always consult with your healthcare provider or pharmacist if you have questions or concerns about your medications.
