Pharmacological properties:

Pharmacodynamics. An antibiotic of a broad spectrum of activity from group of tetracyclines. Works bacteriostatically, suppresses synthesis of protein in a microbic cell by interaction with 30S in subunit of ribosomes. It is active concerning many gram-positive and gram-negative microorganisms: Streptococcus spp., Treponema spp., Staphylococcus spp., Klebsiella spp., Enterobacter spp. (including E. aerugenes), Neisseria gonorrhoeae, Neisseria meningitidis, Haemophilus influenzae, Chlamydia spp., Mycoplasma spp., Ureaplasma urealyticum, Listeria monocytogenes, Rickettsia spp., Typhus exanthematicus, 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. (except Clostridium difficile), Actinomyces spp., Fusobacterium fusiforme, Calymmatobacterium granulomatosis, Propionibacterium acnes, some protozoa (Entamoeba spp., Plasmodium falciparum).
As a rule, does not affect Acinetobacter spp., Proteus spp., Pseudomonas spp., Serratia spp., Providencia spp., Enterococcus spp.
It is necessary to take into account a possibility of the acquired doxycycline resistance at a number of activators which often is cross in group (i.e. the strains steady against doxycycline, at the same time will be steady against all group of tetracyclines).

Pharmacokinetics. Absorption 
Absorption - bystry and high (about 100%). Meal slightly influences drug absorption.
The maximum level of doxycycline in a blood plasma (2,6-3 mkg/ml) is reached in 2 h after reception of 200 mg, in 24 h concentration of active agent in a blood plasma decreases to 1,5 mkg/ml.
After reception of 200 mg in the first day of treatment and 100 mg a day in the next days the level of concentration of doxycycline in a blood plasma makes 1,5-3 mkg/ml.

Distribution
Doxycycline reversibly contacts proteins of plasma (80-90%), well gets into bodies and fabrics, it is bad – in cerebrospinal fluid (10-20% of level in a blood plasma), however concentration of doxycycline in cerebrospinal fluid increases at an inflammation of a spinal cover.
Distribution volume - 1,58 l/kg. In 30–45 minutes after intake doxycycline is found in therapeutic concentration in a liver, kidneys, lungs, a spleen, bones, teeth, a prostate gland, eye tissues, in pleural and ascitic liquids, bile, synovial exudate, exudate of Highmore's and frontal sinuses, in liquid of gingival furrows.
At normal function of a liver drug level in bile is 5-10 times higher, than in plasma.
In saliva 5-27% of the size of concentration of doxycycline in a blood plasma are defined.
Doxycycline gets through a placental barrier, in small amounts cosecretes in breast milk.
Collects in dentine and a bone tissue.
Metabolism
Insignificant part of doxycycline is metabolized.

Removal
The elimination half-life after a single dose inside makes 16-18 h, after reception of repeated doses – 22-23 h.
About 40% of the accepted drug are excreted by kidneys and 20 - 40% are removed through intestines in the form of inactive forms (chelates).

Pharmacokinetics in special clinical cases
The drug elimination half-life at patients with renal failures does not change since its excretion through intestines increases.
The hemodialysis and peritoneal dialysis do not influence concentration of doxycycline in a blood plasma.

In the presence of renal (клириенс creatinine less than 60 ml/min.) and/or a liver failure decrease in a daily dose of doxycycline as at the same time there is its gradual accumulation in an organism (risk of a hepatotoxic action) is required.


Features of use:

There is a possibility of cross stability and hypersensitivity with other drugs of a tetracycline row.
Tetracyclines can increase a prothrombin time, purpose of tetracyclines at patients with coagulopathies has to be controlled carefully.
The anti-anabolic effect of tetracyclines can lead to increase in level of residual nitrogen of urea in blood. As a rule, it has no essential value for patients with normal function of kidneys. However at patients with a renal failure increase of an azotemia can be observed. Use of tetracyclines for patients with a renal failure demands medical control.
At prolonged use of drug periodic control of laboratory indicators of blood, function of a liver and kidneys is required.
Due to the possible development of a photodermatitis restriction of insolation is necessary during treatment and within 4-5 days after it.
Prolonged use of drug can cause dysbacteriosis and thereof – development of a hypovitaminosis (especially group B vitamins).
For prevention of the dispeptic phenomena it is recommended to accept drug during food.

Features of influence on ability to drive the car and to manage mechanisms were not investigated.


Side effects:

From digestive tract:
anorexia, nausea, vomiting, dysphagy, diarrhea, coloenteritis, pseudomembranous colitis.

Dermatological and allergic reactions:
small tortoiseshell, photosensitization, Quincke's disease, anaphylactic reactions, aggravation of a system lupus erythematosus, makulopapulezny and erythematic rash, pericardis, exfoliative dermatitis.
From a liver:
damage of a liver (at long administration of drug or at patients with a renal or liver failure).
From kidneys: the increase in residual nitrogen of urea caused by anti-anabolic effect of drug.
From system of a hemopoiesis:
hemolitic anemia, thrombocytopenia, neutropenia, eosinophilia, decrease of the activity of a prothrombin.
From a nervous system:
high-quality increase in intracranial pressure (anorexia, vomiting, headache, hypostasis of an optic nerve), vestibular disturbances (dizziness or instability).
From a thyroid gland:
at patients, it is long receiving doxycycline, perhaps reversible dark brown prokrashivaniye of tissue of thyroid gland.
From teeth and bones:
doxycycline slows down bone formation, breaks normal development of teeth in children (it is irreversible color of teeth changes, the enamel hypoplasia develops).
Another:
candidiasis (stomatitis, glossitis, proctitis, vaginitis) as manifestation of superinfection.


Interaction with other medicines:

The antacids containing aluminum, magnesium, calcium, iron preparations, Natrii hydrocarbonas, magnesium - the containing laxatives reduce doxycycline absorption therefore their use has to be divided by an interval of 3 h.
Due to the suppression by doxycycline of intestinal microflora the prothrombin ratio decreases that demands dose adjustment of indirect anticoagulants.
At a doxycycline combination to the bactericidal antibiotics breaking synthesis of a cell wall (penicillin, cephalosporins), efficiency of the last decreases.
Doxycycline reduces reliability of contraception and increases the frequency of acyclic bleedings at reception estrogen - the containing hormonal contraceptives.
Ethanol, barbiturates, rifampicin, carbamazepine, Phenytoinum, etc. stimulators of a microsomal oxidation, accelerating doxycycline metabolism, reduce its concentration in a blood plasma.
Simultaneous use of doxycycline and Retinolum promotes increase in intracranial pressure.
