Common use

Biaxin belongs to the group of macrolide antibiotics that inhibit bacterial protein synthesis. This action is predominantly bacteriostatic, but can also be bactericidal. Macrolides tend to accumulate in leukocytes and be transported to the site of infection. Biaxin/Clarithromycin is effective against Haemophilus influenzae, Streptococcus pneumoniae, Mycoplasma pneumoniae, Staphylococcus aureus, mycobacterium avium and many others, therefore it is used to treat many types of bacterial infections of the skin and respiratory system, stomach ulcers caused by Helicobacter pylori.

Active ingredient: Clarithromycin
Biaxin: 250 mg/500 mg

Biaxin – antibacterial agent of group of macroleads, semi-synthetic derivative of erythromycin. Biaxin is prescribed for treatment of infectious processes caused by flora, sensitive to it: sinusitis, pharyngitis, tonsillitis; folliculitis, streptoderma, erysipelatous inflammation, staphyloderma; bronchitis, community-acquired or hospital-acquired pneumonia; infections of dentoalveolar system; local or widespread mycobacterial infections caused by Mycobacterium intracellulare or Mycobacterium avium; in a complex of medicine oppressing acidity of a gastric acid for eradication of Helicobacter infection.

One of the most common diseases of the digestive system is stomach and duodenal ulcers. With this disease, the mucous membrane is damaged with the subsequent formation of a local defect – an ulcer.

What is a peptic ulcer?

An ulcer is a disorder of the mucous membrane of the stomach or duodenum in which the natural protective gel becomes thinner and is unable to cope with the aggressive contents of the stomach (acid and enzymes). The lesion can affect both the upper layer of the mucosa and the entire membrane.
According to statistics, duodenal ulcers are much more common (4 times) than gastric ulcers, and men are more susceptible to this disease than women.

What are the causes of the development of stomach and duodenal ulcers?

For a long time it was impossible to establish the cause of the development of peptic ulcer disease, but over time, scientists were able to discover that in most cases the causative agent of the disease is the bacterium Helicobacter pylori.

In more rare cases, the following factors can lead to an ulcer:

  • taking certain medications (non-steroidal anti-inflammatory drugs, painkillers and medicines against rheumatism);
  • celiac disease;
  • problems with blood circulation in the intestinal walls;
  • gastrinoma (tumor of the islet apparatus of the pancreas);
  • crohn’s disease;
  • chronic obstructive pulmonary disease;
  • renal failure;
  • lymphoma;
  • psychosomatic disorders.

What is known about Helicobacter pylori?

Helicobacter pylori is a gram-negative bacterium that resembles a spiral shape, thanks to which it easily penetrates and moves in the mucous layer of the stomach and duodenum. In this case, the disease is asymptomatic until the formation of an ulcer.

How does peptic ulcer disease progress?

When a person develops a mucosal lesion, it is accompanied by discomfort or pain while eating (in the case of a stomach ulcer) and pain at night (in the case of a duodenal ulcer).

Other symptoms include:

  • nausea;
  • anorexia;
  • feeling of heaviness in the stomach;
  • painful burning sensation some time after eating.
  • heartburn.

When bleeding begins, the symptoms are accompanied by vomiting, which resembles coffee grounds and dark, tarry stools in appearance.

What is ulcer perforation?

A perforation is essentially a hole that forms in the wall of the stomach or duodenum. The danger of this condition is that the contents of the stomach or intestines leak into the abdominal cavity. In this case, the person feels acute stabbing pain, tension in the abdominal muscles, nausea and vomiting. After which the so-called stage of “imaginary well-being” begins. Feeling temporarily improves while diffuse peritonitis develops in the body. This is an extremely serious condition requiring surgical intervention and restoration of the functioning of internal organs.

How is peptic ulcer treated?

Since most cases of ulcers are infectious in nature, treatment consists of ridding (eradicating) the body of Helicobacter pylori. The European group studying this bacterium proposed a treatment that later became universal, and is aimed at achieving the following goals:

  1. Elimination of the need to adhere to a strict diet during treatment thanks to the use of so-called proton pump inhibitors – drugs that reduce the secretion of hydrochloric acid in the stomach.
  2. Prescribing combination medications to reduce the amount of drugs consumed.
  3. Prescription of long-acting forms, which reduce the number of medications taken.
  4. Reducing the duration of therapy.

One of the drugs that is included in the standard treatment regimen is the clarithromycin-based antibiotic Biaxin.

How does Biaxin work for peptic ulcers?

Biaxin is an antibiotic from the macrolide group that blocks protein synthesis inside Helicobacter pylori, thus exhibiting bacteriostatic and bactericidal action (stops the proliferation of bacteria and destroys them).
When taken orally, it is absorbed in the gastrointestinal tract and accumulates to a constant concentration within 2 days. It binds well to blood plasma and is excreted from the body mainly through the kidneys.

What side effects are possible when taking Biaxin?

Biaxin is a broad-spectrum antibiotic, therefore it affects the intestinal microflora, which often results in stomach upset. Therefore, it is very important to take appropriate measures to relieve unpleasant symptoms such as nausea, abdominal pain and diarrhea.

Possible adverse reactions also include the following:

  • impaired platelet production;
  • disorders of the nervous system (headaches, sleep problems, nightmares, in rare cases – psychosis, depersonalization and hallucinations);
  • disturbance of the sensory organs (taste disorders, tinnitus, in isolated cases – hearing loss);
  • formation of drug resistance.

In what cases should Biaxin not be taken?

Although the drug is widely used to treat peptic ulcers, its use can be dangerous in some cases. For example, in case of coronary heart disease, taking Biaxin increases the risk of death, which has been proven in clinical studies. It is not recommended to take during pregnancy as there is a potential risk to the development of the fetus. This fact was proven in animal studies of the drug.
Biaxin is dangerous to take for people who have hypersensitivity to certain antibiotics, including those from the macrolide group. Also, the drug is not recommended for patients with porphyria.
Simultaneous use of Biaxin with terfenadine, astemizole, cisapride and pimozide can lead to the development of cardiac arrhythmias.

Where can you buy Biaxin?

Biaxin can be bought at a pharmacy or ordered from an online pharmacy (place your order online). The drug is available without a doctor’s prescription, but you should remember that self-medication is dangerous. If you suspect a stomach ulcer, you need to consult a doctor and undergo the appropriate tests. In addition, the doctor selects a treatment regimen based on health characteristics and the presence of concomitant diseases.

Is it worth buying a cheap Biaxin analogue?

Many people wonder whether it is worth purchasing an analogue of the original drug? The cheap price is really an advantage, because when treating stomach ulcers you will have to buy other drugs. But doubt arises about the quality of the medicine. On our website you can buy generic Biaxin, which is developed based on the same active ingredient (clarithromycin) as the original drug. Thus, generic Biaxin is in no way inferior in quality to the original drug and has an affordable price.
