The medication you mentioned (ANTACIDS LIKE NEXIUM
OR NORMAXIM) is better to be taken before food and pexep cr 12.5 mg , zapiz
.025mg and amitop 10 mg tablets after food. Antacids may reduce absorption and NEXIUM , ZANTAC OR NORMAXIM may interact at metabolism
level but they are usually doesn't require any dose adjustment. If you want to take at a stretch then better you keep interval.
Hope I answered your query.
