Pharmacological action

Broad-spectrum antibiotic tetracycline. Bacteriostatic, It inhibits protein synthesis in the bacterial cell by interacting with the ribosome 30S subunit.

It is active against gram-positive and gram-negative bacteria: Streptococcus spp., Treponema spp., Staphylococcus spp., Klebsiella spp., Enterobacter spp. (including Enterobacter aerugenes), Neisseria gonorrhoeae, Neisseria meningitidis, Haemophilus influenzae, Chlamydia spp., Mycoplasma spp., Ureaplasma urealyticum, Listeria monocytogenes, Rickettsia spp. (incl. Rickettsia prowazekii), Escherichia coli, Shigella spp., Campylobacter fetus, Vibrio cholerae, Yersinia spp. (including Yersinia pestis), Brucella spp., Francisella tularensis, Bacillus anthracis, Bartonella bacilliformis, Pasteurella multocida, Borrelia recurrentis, Clostridium spp. (other than Clostridium difficile), Actinomyces spp., Fusobacterium fusiforme, Calymmatobacterium granulomatosis, Propionibacterium acnes; some protozoa: Entamoeba spp., Plasmodium falciparum.

Usually, are not active against Acinetobacter spp., Proteus spp., Pseudomonas spp., Serratia spp., Providencia spp., Enterococcus spp.

It should take into account the possibility of acquired resistance to doxycycline in a number of pathogens, which is often a cross inside the group (ie. strains, resistant to doxycycline, at the same time be resistant to the group of tetracyclines).

 

Pharmacokinetics

Absorption

Absorption – fast and high (about 100%). Food intake does not significantly affect the absorption of the drug.

Cmax doxycycline plasma (2.6-3 ug / ml) achieved through 2 h after administration 200 mg, through 24 hours the concentration of active substance in blood plasma is reduced to 1.5 ug / ml.

Upon receiving 200 mg on the first day of treatment and 100 mg / day on subsequent days doxycycline concentration in plasma is 1.5-3 ug / ml.

Distribution

Doxycycline is reversibly bound to plasma proteins (80-90%), well into tissue, badly – in the cerebrospinal fluid (10-20% concentration in blood plasma), However, the concentration of doxycycline in the cerebrospinal fluid increases in inflammation of the spinal membranes.

Vd – 1.58 l / kg. Through 30-45 min after oral doxycycline found in therapeutic concentrations in the liver, kidney, light, spleen, bones, teeth, prostate, eye tissues, pleural and ascites, bile, synovial exudate, exudate maxillary and frontal sinuses, in crevicular fluid.

In normal liver function levels of the drug in the bile 5-10 times higher, than in plasma.

Saliva is determined 5-27% of doxycycline concentration values ​​in the blood plasma.

Doxycycline crosses the placental barrier, secreted in small amounts in breast milk.

It accumulates in bone and dentin.

Metabolism

Only a small portion is metabolized doxycycline.

Deduction

T1/2 after a single oral administration of 16-18 no, after receiving repeated doses – 22-23 no.

About 40% the dose is excreted in the biologically active form by tubular secretion in the kidney, 20-40% output via the intestine in the form of inactive forms (chelates).

Pharmacokinetics in special clinical situations

T1/2 doxycycline in patients with impaired renal function does not change, tk. increasing its excretion through the intestine.

Hemodialysis and peritoneal dialysis do not affect the doxycycline concentration in blood plasma.

FROM for the prevention of infections in medical abortion appointed 100 mg for 1 hour before and 200 mg after intervention.

The maximum daily dose Adult – to 300 mg / day, or to 600 mg / day for 5 days at Heavy gonococcal infection. To older children 8 years old with a body weight more 50 kg – to 200 mg, to children 8-12 years old with a body weight of less than 50 kg – 4 mg / kg daily during the entire treatment.

At kidney (CC less than 60 ml / min) and / or liver failure requires reduction of the daily dose of doxycycline, since in this case there is a gradual accumulation of it in the body (the risk of hepatotoxicity).

Contraindications

- Severe liver and / or kidney;

- Porphyria;

- Pregnancy;

- Lactation (breast-feeding);

- Children up to age 8 years;

- Hypersensitivity to the antibiotic tetracycline.

 

Pregnancy and lactation

JUnidoks Soljutab® contraindicated during pregnancy.

The drug is contraindicated during lactation (breast-feeding). Doxycycline is excreted in breast milk.

 

Cautions

There is a possibility of cross-resistance and hypersensitivity to other tetracycline drugs.

Tetracyclines can increase prothrombin time, appointment of tetracycline in patients with coagulopathies should be carefully monitored.

Antianabolichesky effect of tetracyclines may cause an increase in residual blood urea nitrogen. Usually, it is not significant in patients with normal renal function. However, in patients with renal insufficiency may be observed the growth of azotemia. The use of tetracyclines in patients with impaired renal function requires medical supervision.

With prolonged use of the drug requires periodic monitoring of laboratory blood parameters, liver and kidney function.

In connection with the possible development photodermatitis need to limit sun exposure during treatment and during 4-5 days after.

Long term use may cause a dysbacteriosis and thereby – the development of hypovitaminosis (especially B vitamins).

To prevent dyspepsia is recommended to take the drug during meals.

Effects on ability to drive vehicles and management mechanisms

Features of influence on the ability to drive and operate machinery has not been studied.

 

Overdose

Symptoms: increased adverse reactions, cause liver damage – vomiting, febrility, jaundice, azotemia, transaminase elevation, increased prothrombin time.

Treatment: immediately after taking large doses recommended gastric lavage, excessive drinking, if necessary – induction of vomiting. Take activated carbon and osmotic laxatives. Hemodialysis and peritoneal dialysis are not recommended due to the low efficiency.

 

Drug Interactions

Antacids, aluminum-containing, magnesium, calcium, iron supplements, natriya carbonate, magnesium-containing laxatives reduce the absorption of doxycycline, therefore, their use should be divided three-hour intervals.

In connection with the suppression of intestinal microflora doxycycline decreased prothrombin index, that require dose adjustment of indirect anticoagulants.

When combined with bactericidal antibiotics doxycyline, violating cell wall synthesis (penicillins, cephalosporins), the effectiveness of recent declines.

Doxycycline reduces the reliability of contraception and increases the frequency of acyclic bleeding when taking estrogen-containing hormonal contraceptives.

Ethanol, barbiturates, rifampicin, Carbamazepine, phenytoin, speeding up the metabolism of doxycycline, reduce its concentration in blood plasma.

The simultaneous use of doxycycline and retinol improves intracranial pressure.
