Tetracycline, 20 pcs., 100 mg, film-coated tablets
Tetracycline is active against gram-positive microorganisms: Staphylococcus spp. (including Staphylococcus aureus, including penicillinase-producing strains), Streptococcus pneumoniae, Listeria spp., Bacillus anthracis, Clostridium spp., Actinomyces israelii; gram-negative microorganisms: Haemophilus influenzae, Haemophilus ducreyi, Bordetella pertussis, Escherichia coli, Enterobacter spp. (including Enterobacter aerogenes), Acinetobacter spp., Klebsiella spp., Salmonella spp., Shigella spp., Yersinia pestis, Francisella tularensis, Bartonella bacilliformis, Vibrio cholerae, Vibrio fetus, Rickettsia spp., Borrelia burgdorferi, Brucella spp. (in combination with streptomycin); with contraindications to the use of penicillins - Clostridium spp., Neisseria gonorrhoeae, Actinomyces spp.; also active against Calymmatobacterium granulomatis, Chlamydia trachomatis, Chlamydia psittaci, Mycoplasma pneumoniae, Treponema spp. Resistant to tetracycline: Pseudomonas aeruginosa, Proteus spp., Serratia spp., most strains of Bacteroides spp. and fungi, viruses, Streptococcus pyogenes, Streptococcus faecalis.
Pharmacokinetics
Absorption - 75-77%, decreases with food intake, binding to plasma proteins - 55-65%. The time to reach the maximum concentration of the drug in plasma (TCmax) when taken orally is 2-3 hours (2-3 days may be required to achieve therapeutic concentrations). Over the next 8 hours, the concentration gradually decreases. The maximum concentration of the drug in plasma is 1.5-3.5 mg/l (a concentration of 1 mg/l is sufficient to achieve a therapeutic effect).
It is distributed unevenly in the body: the maximum concentration of the drug is determined in the liver, kidneys, lungs and in organs with a well-developed reticuloendothelial system - the spleen, lymph nodes. The concentration in bile is 5-10 times higher than in blood serum. In the tissues of the thyroid and prostate glands, the concentration of tetracycline corresponds to that found in plasma; in pleural, ascitic fluid, saliva, milk of lactating women - 60-100% of the concentration in plasma. It accumulates in large quantities in bone tissue, tumor tissue, dentin and enamel of baby teeth. Penetrates poorly through the blood-brain barrier. With intact meninges, it is not detected in the cerebrospinal fluid or is detected in small quantities (5-10% of the plasma concentration). In patients with diseases of the central nervous system, especially with inflammatory processes in the meninges, the concentration in the cerebrospinal fluid is 8-36% of the concentration in plasma. Penetrates through the placental barrier and into breast milk. Volume of distribution - 1.3-1.6 l/kg.
Slightly metabolized in the liver. The half-life of the drug (T1/2) is 6-11 hours, with anuria - 57-108 hours. It is found in urine in high concentration 2 hours after administration and persists for 6-12 hours; in the first 12 hours, up to 10-20% of the dose is excreted by the kidneys. In smaller quantities (5-10% of the total dose) it is excreted with bile into the intestine, where partial reabsorption occurs, which promotes long-term circulation of the active substance in the body (enterohepatic circulation). Excretion through the intestines is 20-50%. During hemodialysis it is removed slowly.

Tetracin has a pronounced insecticidal effect against cockroaches, ants, bedbugs, fleas, flies, and mosquitoes. The residual effect of the drug lasts about 1 month.
For self-treatment, use a pump sprayer or a household sprayer.
To prepare working emulsions, the product is diluted with water at room temperature, stirring evenly. Calculation of the amount of concentrate required to prepare the working emulsion is given in the table.
Insect type | Concentration of ADV, (%) | Amount of product (ml) per 1 liter of water |
Cockroaches | 0,25 | 22 |
flies | 0,20 | 17,5 |
Fleas | 0,15 | 13 |
Bed bugs | 0,10 | 10 |
Red house ants | 0,10 | 10 |
Mosquitoes: adult larvae | 0,15 | 13 |
0,10 | 10 |
The consumption rate of the working solution is 50 ml/m2 for non-moisture-absorbing surfaces and 100 ml/m2 for moisture-absorbing surfaces. Remove the product from treated surfaces using a wet method - with a rag and a soap-soda solution 24 hours after application, but no later than 3 hours before the start of the working day.
To destroy cockroaches , the working solution is used to treat places where insects accumulate, nest and move, paying special attention to the following places: cracks and holes in floors and walls, door frames, thresholds, floor and ceiling skirting boards, ventilation holes, pipe joints, cladding, kitchen furniture . If there are a large number of insects, the entire room should be treated at once (even those rooms where there were no insects). This is carried out in order to prevent the migration of cockroaches to other territories and their further spread. When insects appear, re-treatment is carried out.
When treating bedbugs , the entire room is often not treated. If the number of parasites is insignificant, only their habitats are treated with the working solution. If there is a high infestation of bed bugs, the areas where wallpaper has peeled off, baseboards, window frames, door frames and ventilation holes, cracks in walls, back walls of furniture, carpets, and mattresses should also be treated. It is not recommended to treat bed linen with the working solution; it must be washed at high temperatures. After 5-7 days, it is recommended to re-treat, as young offspring may appear from the larvae that you may have missed.
To destroy ants , the working solution is sprayed on the places of accumulation and movement (paths) of insects.
When treating fleas , the working solution should expose walls (up to a height of 1 meter from the floor), the entire floor surface, various floor coverings, baseboards and cracks. When processing basements, it is necessary to get rid of garbage and clutter and thoroughly treat the entire room. Pet beds should also be treated and washed well after 24 hours.
When treating against flies and mosquitoes , insect landing sites, as well as external walls, garbage chutes and garbage containers should be treated with a working solution. To destroy mosquito larvae with a working solution, it is necessary to treat the surfaces of closed reservoirs, basements, and large containers with standing water.
