The content of the article
The composition of the drug includes the main active substance norfloxacin. It belongs to the second generation fluoroquinolones. These drugs were obtained by chemical synthesis from nalidixic acid, on the basis of which a number of quinolones were derived. Then fluorine atoms were added to them, which led to an increase in antimicrobial activity.
How does the medicine bactin
The mechanism of action of the drug is based on the suppression of the activity of the cellular enzyme DNA gyrase. This leads to impaired function of the nucleic acid - it does not allow the synthesis of proteins necessary for the life of the microbe, the bacterium dies. Also, the effect is due to the indirect effect on the RNA of the bacterial cell, the stability of the outer membrane and surrounding organelles.
Norfloxacin is well absorbed from the gastrointestinal tract, its bioavailability is 30-40%. But simultaneous intake with food slows down absorption. Therefore, you need to take the medicine long before meals or an hour after. After one to two hours, a peak concentration of the drug is reached in the blood. The drug is withdrawn for a long time. The half-life takes about four hours, and in people with renal failure, the duration of the process can increase. The medicine is able to pass through the hematoplacental barrier and penetrate in small amounts into breast milk. Therefore, pregnant women and during breastfeeding are not prescribed. Large concentrations of norfloxacin are created in the tissues of the genitourinary tract, urine and bile. Up to 30% of the drug is excreted from the body with urine unchanged during the day. Another 30% enter the intestines and are excreted naturally.

Reviews
For many years I had cystitis, which could not be cured by any medications that the doctors prescribed in the clinic. I had to go to an expensive paid hospital. And there I was recommended Norbactin. What is most interesting is a completely inexpensive drug, but, interestingly, it actually cured me.

I have chronic cystitis. Just freeze a little and painful urination and seizing pains begin. Who is sick, he will understand.
I didn’t hesitate for a long time - I went to the pharmacy, since I went to the doctor many times, prescribes the same drugs that the pharmacist will sell.
The pharmacist offered me not expensive, but very good, in her words, the drug. There are ten tablets in the package, you need to take from three to seven days. The tablets are not small, but are swallowed normally. They act mainly as an antimicrobial agent.I came home - I immediately accepted, because I already had no strength to endure. On the second day of admission, my pain and frequent urge to the toilet almost completely disappeared. On the third day, I began to have severe headaches. Noise in the ears, pains in the head were girdle. Nausea appeared, sometimes a gag reflex was manifested. Painkillers did not help relieve headaches. This went on all the days that I drank pills.
When I finished the appointment, I did not immediately realize that the headaches stopped immediately, and the noise in my ears went away, and nausea. But only then it dawned on me that the tablets gave a side effect. The instructions for use say that there may be just all of these ailments. Of course, I understand that there may be a side effect, but not in such quantity. And also, I probably made a mistake at the pharmacy when I asked for an inexpensive drug. In general, I will refuse these pills forever and I do not advise you. No wonder it is advertised, apparently in need.

Norbactin acts quickly, almost immediately after the first pill it becomes easier, pain and urges disappear, but other problems appear. Personally, I have nausea, heartburn, and abdominal pain, and I'm sorry, upset stomach. Just as it is written in the list of side effects in the annotation (((Somehow I survived this, but honestly admit - with difficulty.
