Antibiotics
Antibiotics are among the most commonly prescribed drugs in modern medicine. They are effective in the prevention and treatment of bacterial infections, have saved the lives of millions of people and have become a significant breakthrough for medical science.
There was no effective treatment of bacterial infections prior to the discovery of antibiotics. Antibiotics began to be considered a “miracle cure” after their discovery in the 20s of the last century and the beginning of widespread use in the 40’s.
Antibiotics are the most effective drugs against bacteria. They affect the vital biochemical processes of bacteria resulting in:
| The bacteria structure is destroyed and they die. | The growth and multiplication of bacteria stops. |
If the bacteria make you sick, buy antibiotics and start treatment as soon as possible. Untimely initiation of the treatment increases the risk of a longer and more severe illness.
Proper use of antibiotics allows to cure many infections caused by bacteria including such common ones as:
- urinary tract infections: cystitis, pyelonephritis or urethritis;
- respiratory tract infections: pneumonia or bronchitis;
- skin infections: cellulitis, folliculitis, impetigo or boils;
- gastrointestinal infections: gastroenteritis or traveler’s diarrhea;
- sexually transmitted infections: bacterial vaginosis, syphilis or gonorrhea.
If there is a suspicion of an infection, it is important to know whether it is caused by bacteria or viruses. Antibiotics are ineffective against viruses and viral infections, such as flu or colds.
The body’s immune system usually effectively fights harmful bacteria without antibiotics use. White blood cells enter the infectious area where they attack pathogens. However, when the body’s defense is weakened, for example because of illness, bacteria can begin to multiply rapidly in the body.
| People usually get infected with bacteria that have penetrated into the body from the outside. | Sometimes our “own” bacteria multiply too quickly and cause diseases. |
When bacteria become too much, they begin to release chemical substances called toxins. Such substances may cause pain, damage the body’s tissues and make the person sick.
Antibiotics are used when the person and his immune system need help. Effectiveness of antibiotic therapy largely depends on the rational choice of antibiotics.
There are many different kinds of antibiotics on sale. When choosing antibiotics, such an important factor as the type of infectious agent should be considered. The type of antibacterial agent is chosen depending on the type of bacterium that caused the infection.
Here is a list of the main types of antibiotics and representatives of their classes.
Macrolides
| Aminoglycosides
|
Fluoroquinolones
| Penicillins
|
Cephalosporins
| Tetracyclines
|
When type of infectious agent is identified, a certain antibiotic is prescribed. Some types of antibiotics are effective only against certain types of bacteria and are ineffective against others.
Antibiotics can have a narrow or broad spectrum of activity.
- narrow spectrum: activity against one or more species of bacteria;
- wide spectrum: activity against many types of bacteria.
Antibiotics are manufactured in various dosage forms that are used differently. To treat infections, the dosage forms that most quickly deliver the antimicrobial drug to the infection site are selected.
- Oral antibiotics – liquid, tablets or capsules that need to be swallowed. They are used to treat most types of infections of varying severity.
- Injection antibiotics – is a solution injected by a syringe or through a drop counter into a muscle or blood. They are usually prescribed to treat severe infections.
- Local antibiotics – solutions, lotions, sprays, creams that are used on the external surfaces of the body. They are usually prescribed to treat skin and eye infections.
A dose of antibiotics is determined individually depending on the severity and localization of infection, the patient’s weight and age, as well as functions of the internal organs. The frequency of administration of the recommended doses can be different, usually 1 to 4 times a day.
Relief of symptoms of bacterial infection occurs within a few days. The duration of a treatment course can be different, usually 1-2 weeks.
It is extremely important to complete the course of antibiotics, even if the patient feels better and all the infection symptoms disappear. If to stop the treatment ahead of time:
- the disease can return;
- bacteria can become resistant to antibiotics.
Antibiotics may cause side effects in some patients. Most of them are harmless and short-term. If side effects of antibiotics are severe or unpleasant, it may needed to reduce the daily dose or replace the type of medication used.
Antibiotics are sold at almost every local drugstore or on online pharmacy. However, more and more people prefer to order antibiotics online since this gives many benefits, including:
- purchase of antibiotics at a low price;
- fast home delivery;
- there is no need for a prescription.
