Levomycetin is indicated in the treatment of diseases caused by hemophilic bacteria, chlamydia, rickettsia, brucella, spirochetes. At therapeutic concentrations, Levomycetin has a bacteriostatic effect.

According to the instructions, Levomycetin is weakly active against Pseudomonas aeruginosa, acid-fast bacteria, clostridia and protozoa. Drug resistance to Levomycetin develops relatively slowly, but usually there is no cross-resistance to other chemotherapy drugs.

With topical application of Levomycetin, a therapeutic concentration is created in the iris, cornea, vitreous body, aqueous humor, while Levomycetin does not penetrate into the lens.

Levomycetin according to the instructions is quickly and well absorbed both after oral administration and with rectal administration, reaching a maximum concentration in the blood after a few hours.

Penetrating into the organs, fluids and tissues of the body, Levomycetin penetrates well into the cerebrospinal fluid, as well as into mother's milk.

Package

Compound

The active substance of Levomycetin in all its forms is chloramphenicol, a substance that belongs to the amphenicol group of antibiotics.

Drops in the eyes contain chloramphenicol at a concentration of 2.5 mg / ml.

Possible dosages of the active substance for capsules and tablets are 250 and 500 mg, for prolonged-release tablets - 650 mg (the tablets have 2 layers - the outer contains 250, the inner contains 400 mg of chloramphenicol).

Alcoholic solution of Levomycetin is available in a concentration of 0.25; 1, 3 and 5%. Ointment Levomycetin can have a concentration of 1 or 5%.

Preparations from different manufacturers have a different composition of auxiliary components.

All variants of the same drug produced by pharmaceutical companies in the post-Soviet countries differ slightly, since they use the same technology for producing chloramphenicol. Thus, Levomycetin DIA eye drops do not differ from drops produced, for example, by Belmedpreparaty.

Release form

  • eye drops 0.25% (ATX code S01AA01);
  • liniment 1%, 5%;
  • alcohol solution 1%, 3%, 5% and 0.25% (ATC code D06AX02);
  • tablets and capsules 250 and 500 mg, prolonged-release tablets 650 mg (ATX code J01BA01).

pharmachologic effect

Antibacterial. The drug stops inflammation and cures infections of any tissues and organs, provided that they are caused by microflora sensitive to chloramphenicol.

Pharmacodynamics and pharmacokinetics

Levomycetin is an antibiotic or not? An antibiotic of synthetic origin, which is identical to the product produced by the microorganisms Streptomyces venezuelae in the course of their vital activity.

Chloramphenicol is detrimental to most gram (+) and gram (-) bacteria (including strains that are resistant to the action of sulfonamides, streptomycin and penicillin), spirochetes, rickettsia, and certain large viruses.

Shows low activity against Clostridium, Pseudomonas aeruginosa, acid-fast bacteria and protozoa.

The mechanism of action of the drug is associated with the ability of chloramphenicol to disrupt the synthesis of proteins of microorganisms. The substance blocks the polymerization of activated amino acid residues that are associated with mRNA.

Microbial resistance to chloramphenicol develops relatively slowly; cross-resistance to other chemotherapy drugs, as a rule, does not occur.

When applied topically, the required concentration is created in aqueous humor, vitreous body fibers, cornea and iris. The drug does not penetrate the lens.

Pharmacokinetic parameters when taking chloramphenicol orally:

  • absorption - 90%;
  • bioavailability - 80%;
  • the degree of binding to plasma proteins - 50-60% (in those born before the expected
  • term of babies - 32%);
  • Tmax - from 1 to 3 hours.

Therapeutic concentration in the bloodstream is maintained for 4-5 hours after oral administration. About a third of the dose taken is found in bile, the highest concentration of Levomycetin is created in the kidneys and liver.

The drug is able to pass the placental barrier, its serum concentration in the fetus can reach 30-80% of the serum concentration in the mother. Penetrates into milk.

Biotransformirovatsya mainly in the liver (90%). Under the influence of the normoflora of the intestine, it undergoes hydrolysis with the formation of inactive metabolites.

The elimination time is 24 hours. It is excreted mainly by the kidneys (90%). With the contents of the intestine, from 1 to 3% is excreted. T1 / 2 for an adult - from 1.5 to 3.5 hours, in children 1-16 years old - from 3 to 6.5 hours, in children 1-2 days after birth - 24 hours or more (with low weight body is longer), on the 10th-16th day of life - 10 hours.

Hemodialysis undergoes little.

Indications for use: what are tablets, eye solution and external therapy used for (liniment and alcohol solution)

What does the medicine help? Levomycetin is prescribed for diseases that provoke antibiotic-sensitive microbes: shigella, salmonella, streptococci, staphylococci, strains of Proteus, Neisseria, rickettsia, chlamydia, leptospira, Klebsiella and a number of other microorganisms.

The drug is available in several dosage forms. This allows you to deliver chloramphenicol directly to the lesion and in the concentration necessary for cure.

Indications for the use of Levomycetin in the form of liniment and solution:

  • bacterial infections of the skin, provided that they are caused by microflora sensitive to chloramphenicol;
  • trophic ulcers;
  • bedsores;
  • boils;
  • wounds;
  • infected burns;
  • nipple cracks that occur during breastfeeding.

An alcohol solution in the ears is prescribed to be administered with purulent otitis media.

Side effects

Side effects of Levomycetin systemic nature:

  • disorders of the digestive system - nausea, diarrhea, dyspepsia, vomiting, irritation of the mucous membrane of the pharynx and oral cavity, dysbacteriosis;
  • violations of hemostasis and hematopoiesis - reticulocyto-, leuko- and thrombocytopenia, agranulocytosis, hypohemoglobinemia, aplastic anemia;
  • sensory and nervous system disorders - depression, optic neuritis, mental and motor disorders, headache, impaired consciousness and / or taste, hallucinations (auditory or visual), delirium, decreased visual acuity / hearing;
  • hypersensitivity reactions;
  • attachment of a fungal infection;

Instructions for use Levomycetin

Eye drops Levomycetin: instructions for use

Eye drops Levomycetin (DIA, Akri, AKOS, Ferein) are introduced into the conjunctival sac of each eye, one 3-4 rubles / day. The course of treatment usually lasts from 5 to 15 days.

When using the drug, you should tilt your head back, gently pull the lower eyelid towards the cheek so that a cavity forms between the skin and the surface of the eye, and, without touching the eyelid and the surface of the eye with the tip of the dropper bottle, add 1 drop of medicine into it.

After instillation, the outer corner of the eye is pressed with a finger and does not blink for 30 seconds. If you can’t blink, do it as carefully as possible so that the solution does not spill out of the eye.

For children in the neonatal period (the first 28 days after birth), the drug is used for health reasons.

With purulent otitis media, the drug is injected into the ear 1-2 rubles / day. 2-3 drops. With significant discharge from the ear canal, which wash off the applied solution, Levomycetin can be used up to 4 rubles / day.

Eye drops for barley

The use of chloramphenicol in barley in combination with boric acid, which is part of the solution as an auxiliary component, helps prevent infection of the conjunctiva and the development of complications after opening the abscess, accelerates the ripening of barley, partially relieves redness and reduces the intensity of pain, reduces the time by 2-3 days convalescence.

Treatment is carried out simultaneously for both the patient and the healthy eye. The agent should be instilled 1-2 drops 2-6 rubles / day. With severe pain, Levomycetin can be instilled every hour.

Levomycetin tablets: instructions for use

Tablets and capsules are taken, depending on the indications, 3-4 rubles / day. A single dose of Levomycetin in tablets / capsules for an adult is 1-2 tab. 250 mg. The highest dose - 4 tab. 500 mg per day.

In especially severe cases (for example, with peritonitis or typhoid fever), the dose may be increased to 3 or 4 g / day.

Duration of application - no more than 10 days.

Levomycetin is often used for diarrhea that occurs when food is poisoned, as well as in cases where intestinal upset is the result of a bacterial infection.

Levomycetin tablets for diarrhea are taken before meals, one every 4-6 hours. The highest dose is 4 g / day. If after taking the first 500 mg tablet the disorder has stopped, the second one should no longer be taken.

How to take Levomycetin for cystitis

With cystitis, as a rule, tablets are used. In especially severe cases, the doctor may recommend injections of chloramphenicol (to prepare a solution, the powder is dissolved in water for injection or novocaine) or a jet infusion of chloramphenicol on glucose into a vein.

Unless otherwise indicated, cystitis tablets should be taken at the standard dosage every 3-4 hours.

Instructions for alcohol solution

The solution is intended for lubrication of the affected skin surface or for use under an occlusive dressing.

The duration of treatment depends on the course of the pathological process, its severity and the effectiveness of therapeutic measures.

Cracked nipples should be treated with a 0.25% solution after each feeding. Treatment continues no more than 5 days.

Instructions for liniment

Liniment is applied to the burned skin or wound surface after purulent exudate and dead tissue are removed from it. Before treatment, the wound should also be washed with an antiseptic: 0.01% miramistin solution, 0.05% chlorhexidine bigluconate solution, 3% hydrogen peroxide solution or 0.02% furatsilina aqueous solution.

The ointment is applied to the affected area with a thin layer and then covered with a sterile bandage. You can also soak a sterile gauze cut with the drug and fill the wound with it or cover the burn surface.

In the treatment of wounds, liniment is used 1 rub/day, in the treatment of burns - 1 rub/day. or 2-3 rubles / week, depending on how abundantly purulent exudate is released.

In the treatment of bacterial infections of the skin, Levomycetin is applied to the lesions (after they have been pre-treated) 1 or 2 rubles / day, in a thin layer and without a bandage, if possible, rubbing the medicine until completely absorbed into the affected skin and capturing small areas of healthy skin around the pathological focus.

Wet areas before using the product are dried with a gauze napkin.

In cases where Levomycetin is used under a bandage, it is applied 1 p. / Day.

Single dose - 250-750 mg, daily - 1-2 g of chloramphenicol. For a course of treatment of a patient weighing 70 kg, up to 3 kg of the drug should be consumed.

On the cracks of the nipples, the ointment is applied in a thick layer on a sterile napkin.

Levomycetin for acne

What is Levomycetin? Antibacterial drug. The ability to quickly suppress infectious and inflammatory processes allows the use of a remedy (tablets and alcohol solution) for acne.

For skin problems, a 1% solution is usually recommended. The medicine is applied pointwise so as not to dry out the skin and not provoke the appearance of microbes resistant to chloramphenicol, which in the future can cause the appearance of purulent acne that is difficult to treat.

The solution is used from the moment the pimple appears until it disappears. It is important to remember that the remedy is not intended for prophylactic use.

Chloramphenicol is often used in combination with other treatments to treat acne and red, inflamed pimples.

The most popular are the following acne talkers with Levomycetin:

  • Aspirin, Levomycetin and calendula tincture. Acetylsalicylic acid (aspirin) and chloramphenicol are taken 4 tablets each and, after grinding them into powder, pour 40 ml of calendula tincture.
  • Boric acid, Levomycetin, salicylic acid and ethyl alcohol. To prepare the medicine, the ingredients are mixed in the following proportion: 5 ml of a two percent solution of salicylic acid, boric acid and alcohol - 50 ml each, Levomycetin - 5 g.
  • Salicylic acid, streptocide, camphor alcohol, Levomycetin in the following proportion: 30 ml (2% solution) / 10 tablets / 80 ml / 4 tablets.

Reviews allow us to conclude that these remedies are very effective if acne is single, but if the problem is more extensive, it is necessary first of all to eliminate its cause from the inside.

Overdose

Severe complications from hematopoiesis are usually associated with the use for a long time of doses exceeding 3 g / day. Symptoms of chronic intoxication: pale skin, hyperthermia, sore throat, hemorrhage and bleeding, fatigue or weakness.

Treatment with high doses of newborns can provoke the development of a cardiovascular (“gray”) syndrome, the main features of which are:

  • change in skin color to bluish-gray;
  • hypothermia;
  • bloating;
  • vomit;
  • lack of nervous reactions;
  • violation of the rhythm of breathing;
  • acidosis;
  • circulatory collapse;
  • cardiovascular insufficiency;
  • coma.

In 2 out of 5 cases, the patient dies. The cause of death is the accumulation of the drug in the body due to the immaturity of liver enzymes and the direct toxic effect of floramphenicol on the myocardium.

Cardiovascular syndrome manifests itself when the plasma concentration of chloramphenicol exceeds 50 mcg / ml.

Treatment involves gastric lavage, the use of saline laxatives, enterosorbents, cleansing enema. In severe cases, hemosorption and symptomatic therapy are indicated.

High doses of eye drops may cause temporary visual impairment. If the dose is exceeded, rinse the eyes with running water.

An overdose of external therapy agents may be accompanied by irritation of the skin and mucous membranes, as well as local hypersensitivity reactions.

Interaction

Interaction with topical application is not described.

Chloramphenicol enhances the effect of hypoglycemic drugs (by increasing their plasma concentration and suppressing their metabolism in the liver), as well as the effect of drugs that inhibit bone marrow hematopoiesis.

The drug prevents the manifestation of the bactericidal effect of penicillin. It weakens the metabolism of warfarin, phenobarbital and phenytoin, increasing their concentration in the blood plasma and slowing down their excretion.

In combination with clindamycin, erythromycin and lincomycin, the drugs mutually weaken each other's action.

To prevent an increase in the inhibitory effect on hematopoiesis, chloramphenicol should not be used in conjunction with sulfanilamide drugs.

Terms of sale

Liniment and alcohol solution belong to the group of over-the-counter products. To purchase tablets and eye drops, you need a prescription from a doctor.

Storage conditions

Eye drops, alcohol solution, tablet forms should be stored at temperatures up to 25 ° C, liniment - at a temperature of 15-25 ° C.

special instructions

The State Pharmacopoeia states that chloramphenicol is white/white with a greenish-yellow tinge, bitter in taste and odorless crystalline powder. The substance is poorly soluble in water and readily soluble in 95% alcohol. Almost insoluble in chloroform.

The gross formula of the substance is C₁₁H₁₂N₂O₅Cl₂.

Is it possible to use drops in the nose and in the ear?

In practice, eye drops are used in practice for bacterial rhinitis, in the ear - for purulent otitis media.

Despite the fact that the use of the drug for other purposes cannot be considered correct, such treatment does help in some cases.

Most often, eye forms with a runny nose are prescribed to babies who still do not know how to blow their nose on their own: a large amount of mucus with bacteria, if it enters various sinuses, can provoke complications such as sinusitis or sinusitis.

Despite the fact that the use of Levomycetin drops in infants can dry the mucosa and reduce the flow of snot, it has been proven that topical antibiotics often do not effectively fight a bacterial infection.

If we talk about the treatment regimen according to the “off-label prescription” principle (not for the intended purpose), then Levomycetin is instilled into the ear 3-4 drops, into the nose - 1-2 drops. Treatment lasts from 5 to 10 days. Multiplicity of procedures - 1-2 per day.

Before you make the drug in the nose, you must first drip a vasoconstrictor. Before applying to the ear, the external auditory canal should be cleaned of pus.

Application in veterinary medicine

In veterinary practice, Levomycetin is used for colibacillosis, salmonellosis, leptospirosis, dyspepsia, colienteritis, coccidosis and pullorosis of chickens, infectious laryngotracheitis and mycoplasmosis of birds, urinary tract infections and bronchopneumonia.

The dose for farm animals, as well as for cats and dogs, is selected depending on the weight and severity of the disease.

How to give chickens the drug? To avoid the mass death of chickens from an intestinal infection, they are given 1 tablet of Levomycetin 2 times a day with food for 3-5 days. This dosage is calculated for 15-20 chicks.

Analogues

Preparations with the same active ingredient: Levomycetin Aktitab, Levomycetin sodium succinate.

Analogues according to the mechanism of action:

  • for Levomycetin tablets - Fluimucil;
  • for solution and ointment Levomycetin - aerosol Levovinizol (generic), Bactroban, Baneocin, Gentamicin, Lincomycin, Synthomycin, Fucidin, Fusiderm, Neomycin.

Which is better - Levomycetin or Albucid?

Wikipedia states that Albucid (sulfacetamide) is an antimicrobial bacteriostatic agent from the group of sulfonamides.

The drug is used in ophthalmology for the treatment of bacterial keratitis, purulent ulcers of the cornea, blepharitis, conjunctivitis, chlamydial and gonorrheal diseases in adults, as well as blenorrhea in newborn babies.

Albucid, unlike Levomycetin, causes severe eye irritation.

The use of Levomycetin for children

The use of Levomycetin tablets in pediatrics

Tableted forms of the drug in pediatrics are used under constant monitoring of the serum concentration of chloramphenicol. Depending on age, the dose of Levomycetin tablets for children ranges from 25 to 100 mg / kg / day.

For newborn infants under the age of 2 weeks (including premature infants), the formula for calculating the daily dose is as follows: 6.25 mg / kg for each dose with a frequency of applications up to 4 rubles / day.

For infants older than 14 days, 12.5 mg / kg is prescribed for 1 dose every 6 hours or 25 mg / kg every 12 hours.

In severe infections (for example, meningitis), the dose is increased to 75-100 mg / kg / day.

How to take Levomycetin for diarrhea?

The drug is a fairly serious remedy and therefore should be prescribed by a doctor. However, it is often given to children when needed to relieve an intestinal disorder.

As a rule, the dose for children 3-8 years old is from 375 to 500 mg / day. (125 mg per 1 dose), for children 8-16 years old - 750-1000 mg (250 mg per 1 dose).

With diarrhea, a single use of the drug is allowed. If the child's condition does not improve, and the symptoms persist even 4-5 hours after taking the pill, you should consult a therapist.

Eye drops Levomycetin for children

Eye drops for newborns (in the first 4 weeks after birth) are used only for health reasons.

Levomycetin eye drops for infants are also used with caution. As a rule, an antibiotic is instilled 1 drop into the conjunctival sac of each eye every 6-8 hours.

The use of external therapy in children

The solution is not intended for the treatment of children under 1 year old, liniment is not used to treat premature and newborn babies.

Levomycetin and alcohol

Alcohol and chloramphenicol are incompatible. With simultaneous use with ethanol, there is a high risk of developing a disulfiram-like effect, which is manifested by tachycardia, flushing of the skin, nausea and vomiting, reflex cough, convulsions.

Levomycetin during pregnancy

Levomycetin for external and systemic use is contraindicated in pregnancy. If the drug is prescribed to a nursing woman, the child must be transferred to artificial feeding for the duration of treatment.

If indicated, eye drops can be used in pregnant women and during lactation, however, provided that the dosages recommended by the instructions are not exceeded.

– Paratyphoid A and B;

– Sepsis caused by salmonella;

- Meningitis caused by salmonella;

- Meningitis caused by Haemophilus influenzae;

– Purulent bacterial meningitis;

- Rickettsioses.

Dosage and administration

Doses:

adults (inclasstreating elderly patients): the generally recommended dose is 500 mg every 6 hours (50 mg/kg body weight per day in 4 divided doses). Treatment should be continued for another 2 or 3 days after normalization of body temperature. In severe infections (meningitis, sepsis), this dose may be doubled initially, but it should be reduced as soon as clinical improvement occurs.

Children over 6 years old: 50.0–100.0 mg/kg/day in 4 divided doses.

In children and elderly patients, it is necessary to control the concentration of chloramphenicol in the blood plasma. Recommended peak plasma concentration of chloramphenicol (approximately 2 hours after ingestion): 10–25 mg/l; . The "residual" concentration in the blood plasma before the next dose should not exceed 15 mg / l.

Mode of application: inside, 30 minutes before meals.

If you missland taking the drug, you must take the missed dose as soon as this omission has become noticed. However, ifdThis time of taking coincides with the next dose, do not take the missed dose againdwow. Take the drug in accordance with the recommended regimendozing without doubling the dose to make up for the missed dose.

Levomycetin tablet is notdis divided into parts, therefore, when neobthe use of chloramphenicol at a dose of less than 500 mg, it is recommended to use a medicinal mediumdstvodother productdtelator, providing the possibility of suchaboutPS

Side effect

Like all medicines, chloramphenicol can cause unwanted side effects.breactions, aboutdbut they don't happen to everyone.

The incidence of side effectsdena next yeardtions:

Rarely - may affect up to 1 in 1,000 people: reversible dose-dependent inhibition of bone marrow function and irreversible aplastic anemia, hypoplastic anemia, agranulocytosis.

Frequency unknown ishodI'm fromthemeatingddata, the frequency of occurrence ofdit is impossible to eat: secondary fungal infection, reticulocytopenia, leukopenia, granulocytopenia, thrombocytopenia, erythrocytopenia, pancytopenia, increased bleeding time, hypersensitivity reactions (including allergic skin reactions), angioedema, in the treatment of patients with typhoid fever, the Jarisch-Herxheimer reaction may occur, psychomotor disorders, depression, confusion, peripheral neuritis, headache, optic neuritis, visual and auditory hallucinations, decreased visual acuity and hearing, acidosis cardiovascular collapse, dyspepsia, nausea, vomiting (the likelihood of development decreases when taken 1 hour after eating), diarrhea, irritation of the oral mucosa and pharynx, glossitis, stomatitis, enterocolitis, dysbacteriosis (suppression of normal microflora), paroxysmal nocturnal hemoglobinuria, fever, collapse (in children under 1 year old), "gray syndrome" of newborns *.

* "Gray syndrome" of newborns is accompanied by vomiting, bloating, respiratory disorders, cyanosis. In the future, vasomotor collapse, hypothermia, and acidosis join. The reason for the development of the "gray syndrome" of chloramphenicol, due to the immaturity of liver enzymes, the toxic effect on the myocardium. Lethality reaches 40%.

If you experience any adverse reactions, please consult your physician. Thisrecommendationcovers any possible adverse reactions, including those not listed in the leaflet.treasureabove. You can also reporteadverse reactions to the Adverse Reactions Database (Daystwiyam) to medicines, including reports of drug failurenny drugs. By reporting adverse reactions, you help to get more information about the safety of the drug.

Contraindications

Hypersensitivity to the active and auxiliary components of the drug, a history of toxic reactions to chloramphenicol, active immunization, oppression of bone marrow hematopoiesis, acute intermittent porphyria, glucose-6-phosphate dehydrogenase deficiency, liver and / or kidney failure, psoriasis, eczema, fungal skin diseases, prevention and treatment of mild infections, children under 6 years of age, pregnancy, lactation.

Chloramphenicol is contraindicated in patients taking drugs that can suppress bone marrow function.

Overdose

Levels of chloramphenicol above 25 µg/mL are considered toxic.

If more than 6 tablets are taken, gastric lavage should be performed and symptomatic treatment should be carried out. In case of severe overdose, such as "gray syndrome" in children, it is necessary to quickly reduce the concentration of chloramphenicol in blood plasma using hemoperfusion through ion exchange resins, which will significantly increase the clearance of chloramphenicol.

The most severe consequences of chloramphenicol poisoning can be in young children. With prolonged (exceeding the recommended time) intake in high doses - bleeding (due to depression of hematopoiesis or impaired synthesis of vitamin K by the intestinal microflora).

Treatment: there is no specific antidote. In case of a serious overdose of the drug, symptomatic therapy is recommended - the use of activated charcoal, hemoperfusion. In case of massive overdose, consider exchange transfusion.

Precautionary measures

During the period of treatment with chloramphenicol, alcohol is unacceptable: while taking alcohol, a disulfiram reaction may develop (skin hyperemia, tachycardia, nausea, vomiting, reflex cough, convulsions).

Severe complications from the hematopoietic system are associated with the use of large doses of chloramphenicol (more than 4000 mg / day) for a long time.

The use of the drug during active immunization is contraindicated.

Clostridiumdifficile-associated diarrhea (CDAD) has been reported to occur with the use of virtually all antibacterial agents, including chloramphenicol, and can range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal microflora of the colon, leading to overgrowth WITH. difficile.

WITH. difficile produces toxins A and B, which contribute to the development of diarrhea. Hypertoxin-producing strains WITH. difficile Because these infections may be refractory to antibiotic therapy and may require colectomy, CDAD should be suspected in all patients with antibiotic-induced diarrhea.

A careful history is necessary, as diarrhea may occur up to 2 months after the use of antibacterial drugs.

If CDAD is suspected or confirmed, continued use of non-targeted antibiotics WITH. difficile, must be terminated. Use appropriate fluids and electrolytes, protein supplements, antibiotics against WITH. difficile, surgical evaluation should be performed. Repeated courses of chloramphenicol treatment should be avoided. Treatment should not be carried out before the start of treatment and more than is really necessary.

An excessively high level of the drug in the blood can be observed in patients with impaired liver or kidney function. In such patients, the use of the drug is contraindicated.

The use of chloramphenicol, as with other antibiotics, may lead to overgrowth of non-susceptible organisms, including fungi. If infections caused by non-susceptible microorganisms occur during drug therapy, appropriate measures should be taken.

The use of chloramphenicol can cause severe blood disorders (aplastic anemia, bone marrow hypoplasia, thrombocytopenia, granulocytopenia). There are two types of bone marrow depression associated with the use of chloramphenicol. Mild bone marrow depression is usually observed, dose-dependent and reversible, which can be detected by early changes in blood tests. Very rarely there is a sudden fatal lesion of the bone marrow hypoplasia without previous symptoms. Baseline blood tests should be performed before starting treatment and approximately every two days during drug therapy. Chloramphenicol should be discontinued if reticulocytopenia, leukopenia, thrombocytopenia, anemia, or any other laboratory blood changes occur. However, it should be noted that such studies do not exclude the possible subsequent occurrence of irreversible bone marrow suppression. Concurrent use with chloramphenicol of other drugs that inhibit the function of the red bone marrow is contraindicated.

When using the drug in diabetic patients in tests for the presence of glucose in the urine, false positive results are possible.

Dentistry. The use of the drug leads to an increase in the frequency of microbial infections of the oral cavity, a slowdown in the healing process and bleeding of the gums, which may be a manifestation of myelotoxicity. Dental interventions should, if possible, be completed prior to initiation of therapy.

Previous treatment with cytostatics or radiation therapy. Possible accumulation of chloramphenicol and toxic reactions in the form of bone marrow suppression, impaired liver function.

Geriatric use. Features of use in the elderly have not been sufficiently studied due to the small number of people aged 65 years and older who participated in clinical trials. There are clinical studies showing no difference in therapeutic response to drug treatment between elderly and young patients. However, dose selection for elderly patients should be cautious, usually starting at the lower end of the dosing range. The drug is substantially excreted through the kidneys and the risk of developing toxic reactions may be higher in patients with impaired renal function. Since elderly patients are more likely to have decreased renal function, caution should be exercised in dose selection and renal function should be monitored.

Use during pregnancy and periodlactation

Adequate, well-controlled studies on the use of the drug during pregnancy have not been conducted. Chloramphenicol crosses the placental barrier, but it is not known whether it has a toxic effect on the fetus. The use of the drug during pregnancy is contraindicated.

The drug is excreted in the mother's breast milk. Due to the possibility of developing severe adverse reactions in a child, breastfeeding should be discontinued during treatment with the drug. The development of "gray syndrome" is possible: toxic reactions, including fatal cases, are described in newborns; the signs and symptoms associated with these reactions have been termed "grey syndrome". Cases of "gray syndrome" have been described in newborns born to a mother who received chloramphenicol during pregnancy. Cases up to 3 months of life have been described. In most cases, chlorifenicol therapy was initiated within the first 48 hours of life. Symptoms appeared 3 to 4 days after continuous treatment with high doses of chloramphenicol. The symptoms appeared in the following order:

– bloating with or without vomiting;

- progressive pale cyanosis;

- vasomotor collapse, often accompanied by irregular breathing;

death within a few hours of the onset of these symptoms.

The progression of symptoms is associated with high doses. Preliminary serum studies have shown unusually high concentrations of chloramphenicol (greater than 90 µg/mL on repeated doses). Assistance measures: exchange transfusion or hemosorption. Termination of therapy in the early stages often led to reversal of symptoms until complete recovery.

Influence on the ability to drive transport environmentsdand potentially dangerouswithmechanisms

During the period of treatment, care must be taken when driving vehicles and engaging in other potentially hazardous activities that require an increased concentration of attention and speed of psychomotor reactions.

Interaction with other drugs

Chloramphenicol inhibits the cytochrome P450 enzyme system, therefore, when used simultaneously with phenobarbital, phenytoin, indirect anticoagulants, tolbutamide, there is a weakening of the metabolism of these drugs, a slowdown in excretion and an increase in their plasma concentration. Dose adjustment of anticonvulsants and anticoagulants may be required if they are used concomitantly with chloramphenicol.

With simultaneous use with phenobarbital, a decrease in the concentration of chloramphenicol is possible (it is necessary to control the concentration of chloramphenicol in the blood). Reduces the antibacterial effect of penicillins and cephalosporins.

When combined with penicillins and rifampicin, complex effects (including a decrease / increase in plasma concentration) have been registered, requiring monitoring of plasma concentrations of chloramphenicol.

When used with rifampicin, a decrease in the concentration of chloramphenicol is possible.

Simultaneous administration with drugs that inhibit hematopoiesis (sulfonamides, cytostatics), affecting the metabolism in the liver, with radiation therapy increases the risk of side effects.

When administered with oral hypoglycemic drugs, there is an increase in their action (due to the suppression of metabolism in the liver and an increase in their concentration in plasma).

Calcineurin inhibitors (cyclosporine and tacrolimus): Chloramphenicol therapy may increase plasma concentrations of calcineurin inhibitors (cyclosporine and tacrolimus).

Barbiturates: The metabolism of chloramphenicol is accelerated by barbiturates such as phenobarbital, resulting in a decrease in its plasma concentration.

Estrogens: There is a small risk that chloramphenicol may reduce the contraceptive effect of estrogens.

Paracetamol: The simultaneous use of chloramphenicol in patients receiving paracetamol should be avoided, as the half-life of chloramphenicol is significantly prolonged.

Myelotoxic drugs increase the manifestations of hematotoxicity of the drug. Chloramphenicol is contraindicated in patients receiving drugs that cause agranulocytosis. These include: carbamazepine, sulfonamides, phenylbutazone, penicillamine, cytotoxic agents, some antipsychotics, including clozapine and especially depot antipsychotics, procainamide, nucleoside reverse transcriptase inhibitors, propylthiouracil.

Resistance of microorganisms to chloramphenicol develops slowly.

Pharmacokinetics
Absorption - 90% (fast and almost complete). Bioavailability - 80% after oral administration and 70% - after i / m administration. Communication with plasma proteins - 50-60%, in premature newborns - 32%. The time to reach the maximum concentration (TC max) after oral administration is 1-3 hours, after intravenous administration - 1-1.5 hours. The volume of distribution is 0.6-1 l / kg. Therapeutic concentration in the blood is maintained for 4-5 hours after administration. It penetrates well into body fluids and tissues. Its highest concentrations are in the liver and kidneys. Up to 30% of the administered dose is found in bile. The maximum concentration (C max) in the cerebrospinal fluid (CSF) is determined 4-5 hours after a single oral administration and can reach, in the absence of inflammation of the meninges, 21-50% of the maximum concentration (C max) in plasma and 45-89% - with the presence of inflammation of the meninges. Passes through the placental barrier, the concentration in the serum of the fetus can be 30-80% of that in the mother's blood. Penetrates into breast milk.

The main amount (90%) is metabolized in the liver. In the intestine, under the influence of intestinal bacteria, it is hydrolyzed to form inactive metabolites.

Excreted within 24 hours by the kidneys - 90% (by glomerular filtration - 5-10% unchanged, by tubular secretion in the form of inactive metabolites - 80%), through the intestines - 1-3%. The half-life in adults is 1.5-3.5 hours, in case of impaired renal function - 3-11 hours. The half-life in children from 3 to 16 years is 3-6.5 hours. Poorly excreted during hemodialysis.

Carefully

Patients who have previously received cytotoxic drugs or radiation therapy.

Use during pregnancy and during breastfeeding

The drug is contraindicated during pregnancy and during breastfeeding.

Dosage and administration

Inside (30 minutes before meals, and with the development of nausea and vomiting - 1 hour after eating) 3-4 times a day.

A single dose for adults is 250-500 mg, daily - 2000 mg.

Children over 3 years of age and weighing more than 20 kg are used at 12.5 mg / kg every 6 hours or 25 mg / kg every 12 hours (under the control of the concentration of the drug in the blood serum).

The average duration of treatment is 8-10 days.

Other: secondary fungal infection.

Overdose

Symptoms: oppression of bone marrow hematopoiesis, gastrointestinal disorders, liver and kidney damage, neuropathy (including the optic nerve) and retinopathy.
Treatment: hemosorption, symptomatic therapy.

Interaction with other drugs

Suppresses the enzyme system of cytochrome P450, therefore, with simultaneous use with phenobarbital, phenytoin, indirect anticoagulants, there is a weakening of the metabolism of these drugs, a slowdown in excretion and an increase in their plasma concentration.

Reduces the antibacterial effect of penicillins and cephalosporins.

When used simultaneously with erythromycin, clindamycin, lincomycin, there is a mutual weakening of the action due to the fact that chloramphenicol can displace these drugs from the bound state or prevent them from binding to the 50S subunit of bacterial ribosomes.

Simultaneous administration with drugs that inhibit hematopoiesis (sulfonamides, cytostatics), affecting the metabolism in the liver, with radiation therapy increases the risk of side effects.

When administered with oral hypoglycemic drugs, there is an increase in their action (due to the suppression of metabolism in the liver and an increase in their concentration in plasma).

Myelotoxic drugs increase the manifestations of hematotoxicity of the drug.

special instructions

With the simultaneous administration of ethanol, a disulfiram-like reaction may develop (hyperemia of the skin, tachycardia, nausea, vomiting, reflex cough, convulsions).

In the process of treatment, systematic monitoring of the picture of peripheral blood is necessary.
