Pharmacodynamics and pharmacokinetics

Pharmacodynamics

Furazolidone is an antimicrobial agent derived from nitrofuran. Highly sensitive to it are salmonella, shigella, campylobacter, as well as protozoa (lyabmly, trichomonads) and cholera vibrio. Depending on the concentration has a bactericidal or bacteriostatic effect.
The mechanism of action is the blockade of many enzyme systems of the microorganism. Nitrofurans violate cellular respiration, inhibit the Krebs cycle, and block the biosynthesis of nucleic acids. As a result, the shell of microorganisms or their cytoplasmic membrane is destroyed. Under the action of the drug, the destroyed microbial cells release less toxins. Unlike other antimicrobial agents, they activate the immune system.
It works on strains resistant to some antibiotics. Does not affect anaerobes and Pseudomonas aeruginosa. Stability of microorganisms to the drug occurs rarely.
What is Furazolidone used for? Since it is poorly absorbed in the digestive tract and at the same time high concentrations are created in the gut, it is used for intestinal infections of bacterial and protozoal etiology. In contrast, Furadonin has a low toxicity.

Pharmacokinetics

It is well absorbed when taken orally. It is distributed in tissues and liquids. In liquor with meningitis, the same concentrations are created as in plasma, therapeutic concentrations are also achieved in the lumen of the intestine. Intensively metabolized in the liver to an inactive metabolite. It is excreted by the kidneys (up to 65%), minor amounts are determined in feces,

Furazolidone for cystitis

How effective is this drug with cystitis? If we start from pharmacokinetics, then its greatest concentration is determined in the lumen of the intestine, and hence it follows that the drug will be most effective in intestinal infections. Of the group of nitrofurans in the treatment of urinary tract infections, it is better to use Furadonin, but it is more toxic.
If from cystitis Furazolidone can be used as monotherapy, then under pyelitis and pyelonephritis it is prescribed in combination with antibiotics. The derivatives of the nitrofuran series do not create therapeutic concentrations in the kidney parenchyma, therefore they are used only with cystitis.
Furazolidone tablets from cystitis in usual dosages, which were mentioned above, are used in uncomplicated course of the disease. With hemorrhagic or purulent cystitis, more serious treatment is required.

Furazolidone for diarrhea

Is this drug always shown? And is it possible to take it immediately with any disorder of the stool? There are clear indications - shigellosis, amoebic dysentery, salmonellosis.

Sometimes even with acute intestinal infection (OCI) of mild and moderate form, especially in children, treatment is started with probiotics (Bifiform, Probiophore, Enterol, Bifystim) and enterosorbents (Filtrum, Neosmectin, Enterosgel). Only with severe forms or lack of effect from the previous treatment, 2-3 days are prescribed tablets against diarrhea Furazolidone.
Only a doctor can prescribe how to take with diarrhea, and in the absence of positive dynamics, a transition to antibiotics of the "reserve" (Imipenem, Azithromycin, Amikacin, etc.) is possible. Do not forget to take a course of probiotics after treatment.
