The range of medications available at Canadian Health&Care mall is very wide and is thoroughly selected to meet the requirements of customers. The section for Antibiotics includes a few dozen drugs that are most commonly prescribed as a treatment for bacterial infections of different genesis. In this article, we are going to learn more about Top 3 Antibiotics: Zithromax, Amoxicillin, Tetracycline.

What is the difference between antibiotics and other types of drugs?


The notion “antibiotic” can be used for a vast number of medications with various chemical properties. They all have in common the following feature: these drugs can stop the growth and multiplication of bacteria. It should be mentioned, that there are hundreds of bacteria species surrounding us and inhabiting our bodies.

An interesting fact: the total weight of bacteria, normally inhabiting the intestine, is more than a kilo (or two pounds)! All these microorganisms perform a lot of useful functions and are vital for normal body performance. One of the most essential functions is protection from hostile bacteria and support of normal balance of microorganisms within the body.

Use of antibiotics

The most complicated aspect in the use of antibiotics is that they kill both pathogenic and useful bacteria, so the indications for their prescription should be seriously considered by a healthcare provider. Antibiotics should be sold only by prescriptions. The reason for the use of antibacterial drugs is the doctor’s conviction that the inflammatory process is caused precisely by bacteria, not by viruses or fungi, since viruses are resistant to antibiotics, and at the same time most intestinal and catarrhal infections are of a viral nature.

The second problem associated with antibiotic therapy is that not all drugs in this group are effective for all types of bacteria. Therefore, the selection of a specific drug is based on the symptoms typical for a specific kind of bacteria to cause. But even in this case, no one can be completely sure that the antibiotic will help, since a lot of microorganisms have developed resistance to their effects over the years of using and misusing antibacterial drugs. Information on the frequency of resistant strains of specific microbes to specific drugs is constantly updated and sent to doctors. Using these data, medical experts make recommendations on drugs, dosages and treatment plans.

Naturally, patients themselves are unable to correctly choose an effective drug, so it is better to follow the advice of a healthcare provider. Uncontrolled use of antibiotics, especially powerful ones, increases the number of resistant strains of pathogenic microbes. To treat diseases caused by these strains, medical industry requires more and more powerful antibacterial agents, often with stronger side effects.

Another important thing to keep in mind is the necessity to complete the treatment course of antibacterial drug without interruptions and giving it up. It often happens that after one or two days of intake, the fever disappears, the symptoms become less disturbing or disappear, and the patients feel like giving up the medicine.

This is strictly forbidden in any case, as it may lead to a chronic course of the disease, the development of complications, a new outbreak of the disease. Another problem of such an approach is decreased efficacy of the antibiotic for the same bacteria, so the patient must use a more powerful one (with higher risks and more serious side effects).
