Fluoroquinolones are a class of antibiotics approved to treat or prevent certain bacterial infections. The fluoroquinolone antibiotics include ciprofloxacin (Cipro), gemifloxacin (Factive), levofloxacin (Levaquin), moxifloxacin (Avelox), and ofloxacin (Floxin).

Why is aminoglycosides given orally?

Neomycin is used orally to treat hepatic encephalopathy. Because it is poorly absorbed orally, neomycin causes a decrease in intestinal bacteria, thereby decreasing ammonia production and absorption from the colon.

Do aminoglycosides cross placenta?

The aminoglycosides cross the placenta (4) and their con- centration in the amniotic fluid ranges from 30% to 60% of the average maternal concentration in blood. Severe intrauterine otological damage has been reported after the administration of aminoglycosides to mothers (5).
