Tetracyclines should not be administered with calcium-rich products because they form what type of compound?
Correct answer: B. Poorly absorbed chelates
- A. Highly soluble complexes
- B. Poorly absorbed chelates
- C. Rapidly hydrolysed esters
- D. Strongly acidic metabolites
Explanation
Tetracyclines bind calcium and form poorly absorbed chelates in the gastrointestinal tract. This interaction reduces the amount of active drug reaching the circulation.
