Which of the following drugs should not be taken together with antacids?
a. tetracycline
b. metronidazole
c. penicillin
d. clindamycin
a. Di- or trivalent ions (Mg2+, Ca2+, Al3+) containing antacids bind to and form an insoluble complex with tetracyclines (tetracycline HCl, minocycline HCl, and doxycycline hyclate) and fluoroquinolone (e.g., Cipro), which will decrease the absorption rate of these antibiotics. Thus, antacids should not be given concurrently with these antibiotics but rather one to two hours before or after taking the antibiotics.
