What is the Difference Between Antibiotic and Antiseptic?
🆚 Go to Comparative Table 🆚The main difference between antibiotics and antiseptics lies in their modes of action and the range of microorganisms they target. Here are the key differences:
- Mode of Action: Antiseptics inhibit the growth of bacteria on the skin's surface, while antibiotics kill bacteria directly. Antiseptics are applied topically, whereas antibiotics can be taken orally, intravenously, or topically in the form of a cream or ointment.
- Target Microorganisms: Antibiotics are effective against bacteria only, while antiseptics can target bacteria, viral species, and fungi.
- Side Effects: Antiseptics have minimal side effects, while antibiotics can cause more severe side effects, such as diarrhea, nausea, and rashes.
- Examples: Common antiseptics include hydrogen peroxide, boric acid, alcohol, and iodine. Common antibiotics include Penicillin, Keflex, and Zithromax.
In summary, antiseptics are preventative and applied topically to inhibit the growth of bacteria on the skin's surface, while antibiotics are treatments that kill bacteria directly, with some also targeting fungi and parasites. Antiseptics have minimal side effects compared to antibiotics, which can cause more severe reactions.
Comparative Table: Antibiotic vs Antiseptic
Here is a table highlighting the differences between antibiotics and antiseptics:
Feature | Antiseptics | Antibiotics |
---|---|---|
Effective against | Wide range of microorganisms | Bacteria only |
Mechanism of action | Inhibits growth and development of microorganisms without necessarily killing them | Kills and inhibits the growth and development of bacteria |
Application | Applied topically | Usually taken orally |
Examples | Hydrogen peroxide, boric acid, alcohol, iodine | Penicillin, Keflex, Zithromax |
Antiseptics are applied topically and are effective against a wide range of microorganisms, including bacteria, fungi, and viruses. They inhibit the growth and development of these microorganisms without necessarily killing them. On the other hand, antibiotics are typically taken orally and are effective only against bacteria. They kill and inhibit the growth and development of bacteria.
