HOW METROZOX ORAL SUSPENSION WORKSMetrozox-XL Oral Suspension is a combination of three active ingredients. While two of its ingredients, namely ofloxacin and metronidazole are antibiotics, simethicone is a gas-absorbing agent that improves gastric tolerability of the combination. The antibiotic ingredients interfere with the genetic material of bacteria by impairing its DNA. This kills the infection-causing bacteria, preventing its growth and stopping the infection. On the other hand, Simethicone binds with the gas bubbles produced as a result of the other two ingredients or as a result of some other problem. By doing so, it aids in the removal of gases and provides relief in stomach pain and bloating.
