This means that often a particular antibiotic can act in the required way only on certain types of pathogenic agents.
Meanwhile, most antiseptics are strong against all kinds of infectious agents. At the same time, the resistance of microorganisms to such drugs is very low.
Table
| Antibiotics | Antiseptics |
| True specimens are of biological origin | Chemical composition |
| Many are taken internally | Typically intended for external treatment |
| Selective beneficial activity | The spectrum of action of most of them is very wide |
| May provoke the appearance of side effects | Side effects reactions occur quite rarely |
| Have good absorption | Poor absorption |
| Pathogens can develop resistance to these drugs | The inability of pathogens to resist the action of such compounds |
| Shorter shelf life | Do not lose useful properties for a long time |
