A patient of renal failure has been diagnosed with cholera, so which of the tetracyclines is most suitable for the patient:
All tetracyclines are excreted primarily in the urine except doxycycline. Doxycycline is excreted in the faeces and thus can be used in the presence of renal failure.
Minocycline.
Doxycycline.
Oxytetracycline.
All of the above.
