Overview Generic Zithromax® (Azithromycin) 250mg, 500mg, 1000mg online

More than 20 years of experience in the clinical practice of Generic Zithromax® Azithromycin testifies to its truly worldwide recognition. During this time, the drug has proven itself in the treatment of various infectious diseases, and above all bronchopulmonary infections.

According to the results of a study by the European Society for Antimicrobial Chemotherapy (ESAC) conducted in 2001-2002, in most European countries, macrolides occupy the second place in terms of consumption among antibiotics used in outpatient practice, second only to penicillins. Generic Zithromax® Azithromycin and clarithromycin are among the “top five” most actively sold antimicrobial drugs in the world. The consumption of Generic Zithromax® Azithromycin reaches colossal volumes and continues to increase steadily. In 1999 Azithromycin was the most prescribed macrolide in the world (IMS Drug Monitor, 1999), and its sales in 2002 exceeded 1 billion US dollars.

The reason for such popularity and demand for the drug was the evidence-based clinical efficacy of azithromycin in bronchopulmonary and other infections, along with its optimal pharmacokinetic properties, convenient dosing regimen and good tolerability.

The main properties of azithromycin, which make it possible to maintain a strong position in the treatment of lower respiratory tract infections, are as follows:

  • high activity against the main pathogens of lower respiratory tract infections (S. pneumoniae, H. influenzae, M. catarrhalis, S. aureus, Enterobactericae);
  • activity against intracellular atypical pathogens;
  • low resistance of S. pneumoniae and H. influenzae to azithromycin;
  • high concentration in various bronchopulmonary structures;
  • the presence of a postantibiotic effect;
  • lack of clinically significant interaction with other drugs;
  • convenient dosing mode;
  • availability of the drug in various dosage forms;
  • good portability and proven safety.

History of discovery

A group of researchers at the Croatian pharmaceutical company Pliva, led by Dr. Slobodan Djekic, synthesized azithromycin in 1980. It was patented in 1981, at the same time the discovery of azithromycin was made by Pfizer scientists. In 1986 Pliva and Pfizer signed a licensing agreement that gave Pfizer exclusive rights to sell azithromycin in Western Europe and the United States. Pliva obtained the rights to distribute azithromycin in the markets in Central and Eastern Europe under the brand Sumamed in 1988, Pfizer Zithromax in 1991, and Zentiva Azitrox. A few years later, the Food and Drug Administration (USA) approved AzaSite, an azithromycin-based product, for the treatment of eye infections. AzaSite is currently being marketed in the US by the pharmaceutical company Inspire Pharmaceuticals (

Drug interaction of Generic Zithromax® (Azithromycin)

Antacids (Al3+ and Mg2+-containing), ethanol and food slow down and reduce the absorption of Generic Zithromax® (Azithromycin). With the combined administration of warfarin and azithromycin (in normal doses), no changes in prothrombin time were detected, however, given that the interaction of macrolides and warfarin may increase the anticoagulation effect, patients need careful monitoring of prothrombin time. Increases the concentration of digoxin by weakening its inactivation by the intestinal flora. Ergotamine and dihydroergotamine: increased toxic effects (vasospasm, dysesthesia). Triazolam: decreased clearance and increased pharmacological effect of triazolam. Slows down the excretion and increases the plasma concentration and toxicity of cycloserine, indirect anticoagulants, methylprednisolone, felodipine, as well as drugs undergoing microsomal oxidation (carbamazepine, terfenadine, cyclosporine, hexobarbital, ergot alkaloids (ergotamine and dihydroergotamine), valproic acid, disopyramide, bromocriptine, phenytoin, oral hypoglycemic drugs, theophylline, etc. xanthine derivatives), due to the inhibition of microsomal oxidation in hepatocytes by azithromycin. Lincosamides weaken, and tetracycline and chloramphenicol enhance the effectiveness of azithromycin. Pharmacologically incompatible with heparin.

Generic Zithromax® (Azithromycin) for COVID-19

Generic Zithromax® (Azithromycin) is a potent antibiotic recommended by the FDA when used in combination with Hydroxychloroquine. It has a bactericidal and bacteriostatic effect.

Coronaviruses have been known to science for more than 50 years. They belong to the family of RNA viruses that cause ARVI without serious complications. Covid-19 is a disease caused by a new strain of coronaviruses SARS-CoV-2, that is, it also has a viral nature of origin.

Antimicrobials are designed to fight bacteria that have nothing to do with viruses.

In what cases is the antibiotic Generic Zithromax® necessary?

Pneumonia is one of the most severe complications of the COVID-19 coronavirus, manifested by the development of inflammation in the lung tissue. The cause of the disease is an infection. But the infectious process can be caused by both viruses and bacteria. Therefore, before prescribing treatment, examinations are performed to help recognize the nature of the infection.

Even a simple general blood test helps the doctor in this. Also, bacteriological seeding is used to determine the type of microorganism: a smear is taken from the nasopharynx and sown on a nutrient medium.

If it is determined that pneumonia is caused by bacteria, the patient is prescribed the antibiotic Generic Zithromax®. With a disease of viral etiology, the treatment of pneumonia with coronavirus with these drugs will not be effective.

Most often Generic Zithromax® they are prescribed in a hospital. Their use is justified by the severity of the patient’s condition. Antibiotics are necessary if observed:

  • the temperature is above 38.5°C for 3 or more days
  • discharge with cough of yellow or green sputum
  • chest pain
  • shortness of breath
  • leukocytosis
