The correct answer is Tetracycline and Quinolone antibiotics.
Antacids can interfere with the absorption of tetracycline and quinolone antibiotics when taken simultaneously. The divalent and trivalent cations present in antacids can form insoluble complexes with these antibiotics, leading to reduced absorption and effectiveness.
Levothyroxine absorption, on the other hand, is not significantly affected by antacids. It is recommended to take levothyroxine on an empty stomach to ensure optimal absorption. Therefore, the third option, Levothyroxine, is not correct in this context. The correct answer is Tetracycline and Quinolone antibiotics.
