What is an antibiotic?
Antibiotics are drugs used to fight infections caused by bacteria. They are also called antibacterials. They treat infections by killing bacteria or reducing their growth. How do antibiotics work in our body? If you want to find out, read on!
The first modern antibiotic
The first modern antibiotic was used in 1936. Before antibiotics, 30 percent of all deaths were caused by bacterial infections. Thanks to antibiotics, infections that have been deadly until now are curable. Even today, antibiotics are effective life-saving drugs for people with certain serious infections. They can also prevent less serious infections from getting worse. There are many kinds of antibiotics. Certain types of antibiotics work better for certain types of bacterial infections.
How long do antibiotics take to work?
Antibiotics start working immediately after ingestion. However, you may not feel better for two to three days. How quickly you feel better after antibiotic treatment varies. It also depends on the type of infection you are treating. How do antibiotics work in our body? Most antibiotics need to be taken for 7 to 14 days. In some cases, shorter treatments work just as well. Your doctor will determine the best duration of treatment and the type of antibiotic that is right for you.
When to stop using them
Even if you feel better after a few days of treatment, it is better to stop the entire course of antibiotics to completely clear the infection. This can also help prevent resistance to antibiotics. Do not stop your antibiotic prematurely without first talking to your doctor.
What are antibiotics made of?
The first beta-lactam antibiotic penicillin was discovered by accident. It arose from a mold spot on a Petri dish. Scientists discovered that a certain type of mushroom produces penicillin naturally. After all, penicillin was produced in large quantities in a laboratory by fermentation with the fungus.
Today, all antibiotics are made in a laboratory
Some occur through a series of chemical reactions that produce the substance used in the drug. Other antibiotics are made, at least in part, by a natural but controlled process. This process is often amplified by certain chemical reactions that can alter the original substance to produce another drug.
What is antibiotic resistance?
Antibiotics are powerful medications that work very well for certain types of illnesses. How do antibiotics work in our body? Some antibiotics are less useful today than before due to increased antibiotics resistance. Antibiotic resistance occurs when certain antibiotics can no longer fight or kill bacteria. In some cases, this may mean that there are no effective treatments for certain conditions.
Clostridium difficile (C. diff)
Overgrowth of this type of bacteria causes infection in both the small and large intestines. This often occurs after someone has been treated with antibiotics for another bacterial infection. C. diff is naturally resistant to many antibiotics.
Vancomycin-resistant enterococci (VRE)
These bacteria often infect the bloodstream, urinary tract, or surgical wounds. This infection usually occurs in hospitalized people. Enterococcal infections can be treated with the antibiotic vancomycin, but VRE is resistant to this treatment.
Methicillin-resistant Staphylococcus aureus (MRSA)
This type of infection is resistant to conventional antibiotics for staphylococcal infections. MRSA infections usually appear on the skin. It is more common in hospitalized people and in people with weakened immune systems.
Carbapenem-resistant Enterobacteriaceae (CRE)
This class of bacteria is resistant to many other antibiotics. CRE infections typically occur in people in hospitals who receive a mechanical ventilator or have an indwelling catheter. The most important cause of antibiotic resistance is the inappropriate or excessive use of antibiotics. Up to 30 percent of the reliable source of antibiotic use is considered unnecessary. This is because antibiotics are often prescribed when they are not needed.
Inappropriate use of antibiotics:
Use antibiotics only for bacterial infections. Don’t use antibiotics for conditions caused by viruses like the common cold, flu, cough, or sore throat. Take antibiotics as directed by your doctor. Using the wrong dose, skipping doses, or taking more or less than specified can contribute to bacterial resistance. Also, if you start to feel better after a few days, talk to your doctor before stopping any antibiotics.
Are you taking the correct antibiotic?
Using the wrong antibiotic when you are infected can lead to resistance. Do not take antibiotics that have been prescribed for someone else. Also, do not take any antibiotics left over from the previous treatment. Your doctor can choose the most appropriate antibiotic for your specific type of infection.
