Cipro® (ciprofloxacin) is a medication licensed to treat a wide variety of bacterial infections. If you are prescribed this antibiotic, you may wonder how the active ingredient in Cipro works to kill certain bacteria.
Cipro's active ingredient is called ciprofloxacin. It is part of a group of medications called fluoroquinolones, or "quinolones" for short. This ingredient works by killing certain bacteria that cause infections. It does this by interfering with two bacterial enzymes called topoisomerase IV and DNA gyrase. These enzymes are needed by the bacteria to copy and repair DNA, important steps required for the bacteria to multiply.
Cipro is approved only for the treatment of certain bacterial infections; it cannot treat bacterial infections that are not susceptible to the active ingredient in this drug. It also cannot treat viral infections, such as the common cold or flu.
