To antibiotics start working, they should get into the blood stream. Usually, antibiotics are produced in form of tablets or capsules for oral intake. In addition, people can buy injectable antibiotics.

Capsules or tablets dissolve and start working within a specific period of time. Injectable antibiotics get into the blood immediately. Despite benefits of injections, most people prefer to buy antibiotic pills. This happens because pills can be used anytime in any place.

Antibacterial substances get into the inflammation center, and according to the type, work in two main directions:

  • Destroying the structure of bacteria
  • Preventing bacterial growth and multiplication

To infectious disease start developing, millions of bacteria should attack the body. Regardless of the way antibiotics work, the pharmacological effect is aimed at preventing the accumulation of a critical number of bacteria. Antibiotics stop the bacterial growth and help the immune system to fight against the disease.

Some antibacterial drugs kill only a certain type of bacteria, and hence they provide a minimum effect on the work of main systems of the body. Other types of antibiotics have a broad spectrum of action and cure many groups of diseases.
