The statistical methods used should be clearly stated and should be the generally accepted techniques refined for this purpose (Peto et al purchase 120mg sildalis erectile dysfunction kansas city. When there is no difference in survival between control and treatment groups sildalis 120mg line erectile dysfunction zinc supplements, the Working Group usually compares the proportions of animals developing each tumour type in each of the groups sildalis 120 mg on line psychological erectile dysfunction drugs. Otherwise buy sildalis 120mg free shipping erectile dysfunction treatment in tampa, consideration is given as to whether or not appropriate adjustments have been made for differences in survival. Several survival-adjusted methods have been developed that do not require this distinction (Gart et al. The nature of the information selected for the summary depends on the agent being considered. For chemicals and complex mixtures of chemicals such as those in some occupa- tional situations or involving cultural habits (e. Concise information is given on absorption, distribution (including placental transfer) and excretion in both humans and experimental animals. Studies that indicate the metabolic fate of the agent in humans and in experimental animals are summarized briefly, and comparisons of data on humans and on animals are made when possible. Comparative information on the relationship between exposure and the dose that reaches the target site may be of particular importance for extrapolation between species. Data are given on acute and chronic toxic effects (other than cancer), such as organ toxicity, increased cell proliferation, immunotoxicity and endocrine effects. Effects on reproduction, teratogenicity, fetotoxicity and embryotoxicity are also summarized briefly. Tests of genetic and related effects are described in view of the relevance of gene mutation and chromosomal damage to carcinogenesis (Vainio et al. The adequacy of the reporting of sample characterization is considered and, where necessary, commented upon; with regard to complex mixtures, such comments are similar to those described for animal carcinogenicity tests on p. The concentrations employed are given, and mention is made of whether use of an exogenous metabolic system in vitro affected the test result. Positive results in tests using prokaryotes, lower eukaryotes, plants, insects and cultured mammalian cells suggest that genetic and related effects could occur in mammals. Results from such tests may also give information about the types of genetic effect produced and about the involvement of metabolic activation. In-vitro tests for tumour-promoting activity and for cell transformation may be sensitive to changes that are not necessarily the result of genetic alterations but that may have specific relevance to the process of carcinogenesis. Genetic or other activity manifest in experimental mammals and humans is regarded as being of greater relevance than that in other organisms. The demonstration that an agent or mixture can induce gene and chromosomal mutations in whole mammals indi- cates that it may have carcinogenic activity, although this activity may not be detectably expressed in any or all species. Relative potency in tests for mutagenicity and related effects is not a reliable indicator of carcinogenic potency. Negative results in tests for mutagenicity in selected tissues from animals treated in vivo provide less weight, partly because they do not exclude the possibility of an effect in tissues other than those examined. Moreover, negative results in short-term tests with genetic end-points cannot be considered to provide evidence to rule out carcinogenicity of agents or mixtures that act through other mechanisms (e. Factors that may lead to misleading results in short-term tests have been discussed in detail elsewhere (Montesano et al. When available, data relevant to mechanisms of carcinogenesis that do not involve structural changes at the level of the gene are also described. The adequacy of epidemiological studies of reproductive outcome and genetic and related effects in humans is evaluated by the same criteria as are applied to epidemio- logical studies of cancer. Structure–activity relationships that may be relevant to an evaluation of the carcino- genicity of an agent are also described. For biological agents—viruses, bacteria and parasites—other data relevant to carcinogenicity include descriptions of the pathology of infection, molecular biology (integration and expression of viruses, and any genetic alterations seen in human tumours) and other observations, which might include cellular and tissue responses to infection, immune response and the presence of tumour markers. Inadequate studies are generally not summarized: such studies are usually identified by a square-bracketed comment in the preceding text. Exposure to biological agents is described in terms of transmission and prevalence of infection. For each animal species and route of administration, it is stated whether an increased incidence of neoplasms or preneoplastic lesions was observed, and the tumour sites are indicated. If the agent or mixture produced tumours after prenatal exposure or in single- dose experiments, this is also indicated. Toxi- cological information, such as that on cytotoxicity and regeneration, receptor binding and hormonal and immunological effects, and data on kinetics and metabolism in experi- mental animals are given when considered relevant to the possible mechanism of the carcinogenic action of the agent. The results of tests for genetic and related effects are summarized for whole mammals, cultured mammalian cells and nonmammalian systems. When available, comparisons of such data for humans and for animals, and parti- cularly animals that have developed cancer, are described. Thus, for example, the action of an agent on the expression of relevant genes could be summarized under both the first and second dimensions, even if it were known with reasonable certainty that those effects resulted from genotoxicity. It is recognized that the criteria for these evaluations, described below, cannot encompass all of the factors that may be relevant to an evaluation of carcinogenicity. In considering all of the relevant scientific data, the Working Group may assign the agent, mixture or exposure circumstance to a higher or lower category than a strict inter- pretation of these criteria would indicate. An evaluation of degree of evidence, whether for a single agent or a mixture, is limited to the materials tested, as defined physically, chemically or biologically. When the agents evaluated are considered by the Working Group to be sufficiently closely related, they may be grouped together for the purpose of a single evaluation of degree of evidence. The Working Group seeks to identify the specific exposure, process or activity which is considered most likely to be responsible for any excess risk. The evaluation is focused as narrowly as the available data on exposure and other aspects permit. The evidence relevant to carcinogenicity from studies in humans is classified into one of the following categories: Sufficient evidence of carcinogenicity: The Working Group considers that a causal relationship has been established between exposure to the agent, mixture or exposure circumstance and human cancer. That is, a positive relationship has been observed between the exposure and cancer in studies in which chance, bias and confounding could be ruled out with reasonable confidence. Limited evidence of carcinogenicity: A positive association has been observed between exposure to the agent, mixture or exposure circumstance and cancer for which a causal interpretation is considered by the Working Group to be credible, but chance, bias or confounding could not be ruled out with reasonable confidence. Inadequate evidence of carcinogenicity: The available studies are of insufficient quality, consistency or statistical power to permit a conclusion regarding the presence or absence of a causal association between exposure and cancer, or no data on cancer in humans are available. Evidence suggesting lack of carcinogenicity: There are several adequate studies covering the full range of levels of exposure that human beings are known to encounter, which are mutually consistent in not showing a positive association between exposure to the agent, mixture or exposure circumstance and any studied cancer at any observed level of exposure. A conclusion of ‘evidence suggesting lack of carcinogenicity’ is inevitably limited to the cancer sites, conditions and levels of exposure and length of observation covered by the available studies. In addition, the possibility of a very small risk at the levels of exposure studied can never be excluded. In some instances, the above categories may be used to classify the degree of evi- dence related to carcinogenicity in specific organs or tissues.

The ultimate resolution of the scanning electron microscope is used to deter- mine the size of the electron probe discount 120mg sildalis overnight delivery erectile dysfunction pills in pakistan. It is well recog- nized that the spatial resolution of an electron microscope is mainly restricted by lens aberrations buy sildalis 120mg low cost erectile dysfunction of diabetes. Diffraction patterns from various regions surrounding the island show that the rafts are ordered in various structures adjacent to the built-up islands buy sildalis 120 mg cheap erectile dysfunction vacuum pumps australia. For example buy 120 mg sildalis otc erectile dysfunction nicotine, by implementation of an aberration correction system in the scanning electron microscope, Batson et al. In an electron microscope, the spectra are collected by passing the high-energy (100–1000 keV) electron beam, focused down to a small probe, through a thin film and recording the transmitted energy loss spectrum. If the probe is scanned over the sample, the result may be presented as a map of chemical composition. This thus forms a powerful tool in composition mapping, which can be achieved at atomic resolution. It is the highest resolution that can be achieved by all the available tech- niques of structural analysis. The yellow square shows the area used for sample drifting correction: to correct the sample drift during data acqui- sitions. A typical electron energy loss spectrum (raw data without any process) is shown in Figure 12(B), in which an edge can be found for O atoms at 532 eV (the core-loss edge of oxygen). A combination of imaging and spectroscopic techniques provides us a powerful tool for the nanostructural analysis. In an electron microscope, a variety of detectors are arranged around the sam- ple. By detecting the characteristic X ray emitted from the sample activated by high- energy electrons, the composition can be identified. The area in the yellow rectangle is defined to correct sample drift, while the green line defines the line for which energy-dispersive spectrum is collected for each point. Figure 13(B) shows a typ- ical energy-dispersive spectrum of the core–shell nanoparticle when the beam is scanned through both the core and the shell. Figure 13(C) shows the line profile of both Si and Fe peaks by using their integrated energy-dispersive intensity at each stop.

Structural Fingerprinting of Nanocrystals in the Transmission Electron Microscope: Utilizing Information on Projected Reciprocal Lattice Geometry, 2D Symmetry, and Structure Factors Peter Moeck and Sergei Rouvimov Laboratory for Structural Fingerprinting and Electron Crystallography, Department of Physics, Portland State University, Portland, Oregon, U. The main emphasis of this chapter is on an outline of the theoretical foun- dation of these two structural fingerprinting strategies. Note that we published recently an extensive review of structural fingerprint- ing strategies in the transmission electron microscope (10). The term “traditional” refers here to strategies that combine information on the projected reciprocal lattice geometry with either spectroscopic information as obtainable from an analytical transmission electron microscope from the same sample area or prior knowledge on the chemical composition of the sample. In contrast, the novelty of the advanced strategies that are briefly described here is due to the combination of information on the projected reciprocal lattice geometry with information on the two-dimensional (2D) symmetry, and structure factor moduli or phase angles. These strategies are applicable only to nanocrystals, 270 Structural Fingerprinting of Nanocrystals in the Transmission Electron Microscope 271 since they rely on kinematic or quasi-kinematic scattering approximations. A brief discussion of powder X-ray fingerprinting and its limitations is also given. Note that kinematic and quasi-kinematic approximations to the scattering of fast electrons do allow for the successful solving and refining of unknown crystal structures [see Ref. Although with much more data processing, this is achieved on the basis of the same kind of data that are employed in our advanced structural fingerprinting strategies. In order for “2D symmetry” and “structure factor fingerprinting” to yield a more discriminatory identification of nanocrystals that cannot already be distin- guished on the basis of their projected reciprocal lattice geometry, one may need only qualitative or semiquantitative information while structural electron crystal- lography needs to employ fully quantitative information. The corollary that it “is always possible, even easy, to collect intensity data that cannot be analyzed by conventional phasing methods or to record high-resolution images where the resemblance to any known structure is not at all obvious” (12) by Douglas L. Lindo Patterson Award laureate, is to be taken very seriously in the structural fingerprinting of nanocrystals. In order to allow the reader to appreciate the limits that dynamical electron scattering effects set on the application of our novel structural fingerprinting strategies, theory sections on kinematic and quasi-kinematic approximations to the scattering of fast electrons are given. This approach is analogous to the one typically taken in structural electron crystal- lography and constitutes the first pillar of structural fingerprinting. Because model structures from a comprehensive database form the second pillar of structural fingerprinting and semiquantitative structure factor information suffices, the task 272 Moeck and Rouvimov is reduced to finding the one model structure that fits a certain set of experimental data best. A short section on criteria for deciding what is the best fit to the model data is presented in the following text. The typical hierarchy of dynamical diffrac- tion corrections to quasi-kinematic data and the “principle of minimal corrections” are also illustrated. The term “phase” has different meanings in different branches of the natu- ral sciences. This is because the structure factor phases are (reciprocal space) entities that are directly related to the Fourier coefficient phases of that electrostatic potential. Finally, the mainly inorganic subset (15) (with some 20,000 entries) of the Crys- tallography Open Database (16–18) (with currently more than 70,000 entries over- all) needs to be mentioned here because we are in the process of interfacing open- access search-match capabilities to this database. This ensures that the relative large abundance of structural 3D information can be utilized for the fin- gerprinting (at just one orientation of the sample in a diffractometer). The angular position and relative heights of Bragg peaks in X-ray diffractograms constitute the information that is principally employable for structural fingerprinting. Since there is no simple experimental test as to the presence of textures in the crystalline pow- der when the very popular Bragg-Brentano parafocusing diffractometer geometry is employed, the information on the relative peaks heights is often not utilized in structural fingerprinting. Advanced structural fingerprinting strategies in powder X-ray diffractometry do, however, utilize fitting procedures to the whole pattern (21). There are several strong peaks so that both a Hanawalt search (22) and a Fink search would work well for the identification of this crystalline material. This powder diffraction pattern was simulated with the freeware program Mercury, Cambridge Crystallographic Data Centre, downloadable at http://www. While a “Hanawalt search” (22) employs the angular positions (reciprocal lattice vectors) of the three most intense X-ray powder diffraction peaks, a “Fink search” utilizes the eight (or 10) shortest reciprocal lattice vectors with reasonably high peak intensities (Fig. Utilizing either or both of these classical search strate- gies leads, usually together with some prior knowledge of chemical information, to an identification of an unknown by comparison with the entries of a comprehensive database such as the well-known Powder Diffraction File (23). The powder X-ray method works best for crystal sizes in the micrometer range, in which kinematic X-ray diffraction on otherwise almost perfect crystal lattices results essentially in delta functions for the line profiles of the individual reflections. The convolution of these delta functions with the instrumental broaden- ing function of a diffractometer determines the shape and width of Bragg peaks in a powder X-ray diffractogram.

Peterburg Research Institute of Pure Biochemicals purchase sildalis 120 mg with mastercard erectile dysfunction meditation, on the development of alloxan diabetes in rats discount 120 mg sildalis overnight delivery impotence law chennai. The absolute insulin deficiency of the direct - cytotoxic genesis was induced with help of the single subcutaneous injection of alloxan in a dose of 150 mg / kg of white mongrel rats weighing 160-220 g discount 120 mg sildalis fast delivery erectile dysfunction and heart disease, which were kept at a pre-day starvation diet generic 120mg sildalis otc impotence because of diabetes. When decapitation, blood was collected and liver isolated for biochemical studies. Raleukin and anakinra unlike metformin significantly increased insulin levels in the blood serum of animals in 2,2-2,4 times. Under the influence of raleukin Hb content in blood serum of rats was significantly increased by 1. Against the background of metformin Hb content was significantly increased in 1,1 times, HbA1c - decreased by 1. The use of studied drugs contributed to the normalization of lipid peroxidation product levels in rat liver homogenates. The results of these studies indicate the prospects of further experimental study of the anti-diabetic properties of raleukin for subsequent inclusion of the drug in the complex of type I diabetes therapy. Diabetes mellitus and metabolic syndrome are widely-spread problems of the modern society. As the patients are becoming more interested in traditional herbal medicines, the verification of their effects is needed. Phytotherapy in the most cases is supplementary, but it may augment the efficacy of the commonly used antihyperglycemic drugs. Goutweed is a perennial herb of the Apiaceae family that has been used in folk medicine for a long time. Goutweed tincture renders protective activity in alloxan-induced diabetic mice, the tincture shows hypoglycemic properties under the conditions of metabolic disorders induced by fructose and hydrochlorothiazide in rats. Oral glucose tolerance test was performed after the treatment of the animals with metformin, goutweed tincture or their combination. The total area under the blood glucose curve was calculated using the trapezoidal method, the average glycemia value was also calculated. Given that glucose and lipid metabolism disorders are interrelated in the pathogenesis of metabolic syndrome and other ―disease of civilization,‖ the same test was also performed in dyslipidemic animals. In dexamethasone treated rats, goutweed tincture combined with the respectively low dose of metformin increased the effect on the latter on the basal glycemia. In the oral glucose tolerance test the lowest area under glucose curve and average glycemia value were seen in these group. The efficacy of the investigated combination was also partially manifested in dyslipidemic animals (the reduction in area under glucose curve). Goutweed tincture is able to partially increase the efficacy of metformin in dexamethasone treated and dyslipidemic rats. Nosocomial infections involving Staphylococcus aureus and methicillin-resistant S. One strategy to combat these infections is to develop novel and effective anti-infective agents. The data from the literature search and study of new antibiotics, clinical trial information. A new group of drugs was discovered recently: Pentaalkylcyclopentadienyl (Cp * g) of 1,2-diamine complexes of transition metals. There were synthesized a series of compounds differing in the structure of the radical in the ligand. Hemolytic activities of the transition metal-complexes as well as toxicity toward Vero cells were also measured. The transition metal complex of Cp*R Ir with cis-1,2-diaminocyclohexane, had strong antibiotic activity against S. A cyclopentadienylcobalt complex of cis-1,2- diaminocyclohexane also showed significant anti-microbial activity against both S. Conclusions: The transition metal complexes described here show specific activity against S. In addition, the specificity of the complexes that show activity indicates that there are specific structure/activity relationships that must be met. The combination of high and specific activity for certain complexes, the low cytotoxicity as tested with Vero cells and the low hemolytic activity all suggest that this transition metal platform may prove to be useful in overcoming antibiotic resistance in S. The imidazole nucleus is a known structural fragment of many natural physiologically active compounds and effective synthetic medicinal products, which are characterized by a wide range of pharmacological properties, among which the antioxidant activity deserves special attention. But despite the considerable synthetic and biological potential of the imidazole nucleus the methods of synthesis and the properties of this heterocyclic type had not been adequately studied yet. The search of new biologically active compounds with antioxidant activity among the imidazole derivatives functionalized with the carboxymethylthiol fragment. Previously in the department of medical and pharmaceutical chemistry we synthesized a number of imidazole derivatives functionalized in the position 4 with carboxymethylthiol fragment, and in the position 5 – with the formyl group, [(1-aryl-5-formyl-1Н-imidazole-4-yl)thio]acetic(propanoic) acids and [(1-arylimidazole-5-yl)methylthio]alkane carboxylic acids in particular. The content of malonaldehyde in the samples was determined by the reaction with the thiobarbituric acid. The results of the study have shown that in the in vitro system all of the -1 -3 studied original compounds in the range of concentrations 10 -10 mol/L inhibit the 2+ Fe -ascorbate induced free radical oxidation of lipids and demonstrate a pronounced antioxidant activity. The highest antioxidant activity in vitro was shown by the [(1- phenyl-5-formyl-1H-imidazole-4-yl)thio]acetic acid. At the same time it was determined that the increase of methylene groups‘ quantity in the carboxyalkylthiol fragment does not significantly influence the antioxidant activity of the synthesized compounds. The [(1-phenyl-5-formyl-1H-imidazole-4-yl)thio]acetic acid is the most promising compound for the further research of antioxidant activity in the wider range of concentrations in vitro and in the in vivo system. Stress is the attempt of organism to regenerate the balance, to recover from unusual events, to keep stability of organism internal parameters (homeostasis) against the influence of bad agents. Nowadays the amount of information is increasing, the temp of life is speeding up, long intellectual and mental load has a big influence on people. Using modern complicated technology and machinery very often causes small and big catastrophes, traffic delays, electric power breaks, connection cessations. It is known that 72-80% of car crashes and 70% air crashes happen because of guiltiness of human. The aim of our research was to analyse the cause and sequence of psychoemotional and phycosocial stress by using literature sources. Negative emotional reactions are caused by long conflict situations, difference between expectation and reality, sometimes by responsibility of making a decision. Psychological multiple manifestations can be low self-appraisal, which in future can overgrow into depression, state of anxiety and terror. This is a complicated emotional state, important component of neural and psychical changings. Neurosis is the neuropsychic dysfunction which appears as the attempt of organism to go round stressful situation instead of comprehension of the problem and finding the solution.

Important links of the pathogenesis of this experimental model is the development of rhabdomyolysis effective 120 mg sildalis reflexology erectile dysfunction treatment, myoglobinuria with toxic both glomerular and tubular kidney apparatus order sildalis 120mg visa erectile dysfunction effects on women. Reamberin experimental group was administered 14 days intragastrically at a dose of 5 ml 120 mg sildalis with visa erectile dysfunction gabapentin. The findings of research in the control group show a decrease in serum protein level in 1 generic 120 mg sildalis free shipping erectile dysfunction drugs best. Application of Reamberin on a background of pathology significantly reduces the level of protein in the urine by 1. Reference drug Hofitol also normalized protein indicators, but without reaching the values of the investigated drug in 1. Thus, in the experimental data there is a clear positive dynamics of Reamberin complex influence on the serum and urine protein levels in experimental acute renal injury. These values allow to further explore of nephroprotective, antihypoxic properties. The basis of the secondary prevention is the use medications of long-acting penicillin. In accordance with international recommendations, benzathine benzylpenicillin-G is assigned by deep intramuscular injection once every 4 weeks (in some cases, once every 3 weeks). Children weighing 20-30 kg injected a dose of 600 units, and for all other age patient groups injected dose of 1200000 units. If the patient has allergy to penicillin, macrolides secondary prevention is carried out in cycles of 10 days each month Children who have had rheumatic fever without carditis, secondary prevention is carried out for 5 years or until the age of 21 years old. This inflammation leads to a violation of the secretory, motor, and often the endocrine functions of the stomach and duodenum. Prescribe colloidal bismuth subcitrate in a dose of 4-8 mg/kg per day in combination with amoxicillin at 25 mg/kg and nifuratel 15 mg/kg for 7 days. In the presence of an allergy to penicillin is used in the scheme clarithromycin therapy at a dose of 7. Blockers H2-histamine receptors are used in the schema therapy for children up to 12 years. Ranitidine is prescribed for 75-150 mg at twice a day for 20 minutes before eating or for famotidine 10-20 mg twice a day regardless of the meal. The drug is administered for 7-10 days and then the dose is reduced by 2 times and the treatment continues for 2-3 weeks. In children over 12 years prescribe triple therapy with the aim of eradication of Н. Four- component therapy includes nifuratel, colloidal bismuth subcitrate in combination with amoxycillin or clarithromycin. Omeprazole appoint 10-20 mg (pantoprazole 20-40 mg per day) once a day in the morning before eating for 7-10 days. Four- component therapy is indicated for the ineffectiveness three- component therapy of first-line therapy. The main cause of death, even working age is coronary heart disease due to the development cardiosclerosis. Atherosclerosis is a disease characterized by lesions of artery walls due to the formation of atherosclerotic plaques that have varying degrees of narrowing the lumen, leading to acute or chronic reduction of blood flow to vital authorities. For pharmacotherapy of atherosclerosis use following groups of drugs: statins, fibrates, bile acid sequestrants and other lipid- lowering agents. Of the group of statins are recommend following medication: lovastatin, pravastatin, simvastatin, atorvastatin, rosuvastatin. In addition, cholesterol- lowering statins are used in combination with other lipid-lowering agents: inedzhi (a combination of 20 mg of simvastatin and 10 mg of ezetimibe), and asia-ator (a combination of 10 mg of atorvastatin and 10 mgezetimibu). Quite often, the choice is between atorvastatin and rosuvastatin – modern synthetic statins, has a marked effect lipid-lowering effect. A number of studies have been conduct directly comparing the original atorvastatin and rosuvastatin. The aim of our study was to examine the results of a multicenter study compared the effectiveness of atorvastatin and rosuvastatin. Rosuvastatin has some advantage over atorvastatin in lowering total cholesterol and low-density lipoprotein cholesterol. It has been proved that long-term use rosuvastatin 40mg reduces the diameter of the atherosclerotic plaque in the vessel. Rosuvastatin had significant advantages over atorvastatin in influencing the level of inflammatory markers, as well as the progression of atherosclerosis. Atorvastatin has the largest list of indications for use for both primary and secondary prevention of cardiovascular disease. Rosuvastatin has registered indications for use - secondary prevention of cardiovascular disease. Having conducted a comparative analysis of the effectiveness of atorvastatin and rosuvastatin in the pharmacotherapy of atherosclerosis, we can conclude that both drugs are approve for use and do not have clear benefits to each other. The study of the current standards of care for patients with acute respiratory viral infections. We analyzed the articles, adapted clinical guidelines based on evidence, unified clinical protocols of emergency medical care for acute respiratory infections, including influenza. For each type of virus is the most difficult lesions characteristic of a particular department of the upper respiratory tract with the development of characteristic symptoms. Etiotropic antiviral pharmacotherapy was conduct with influenza (A and B) drugs from the group neuraminidase (oseltamivir, zanamivir). Apply the following drugs: antipyretic agents (ibuprofen, acetominiphen), antihistamines for systemic use (chloropyramine, clemastine, loratadine, dezloratadine, cetirizine), decongestants and other drugs for topical application in the case of diseases of the nose (oxymetazoline, xilometazoline, nafazoline, tramazoline, tetryzoline), antiseptics used for treatment of throat (ambazone, chlorhexidine), expectorants (guaifenesin, marshmallow root, leaf ivy), mucolytic drugs (acetylcysteine, bromhexinum, ambroxol, carbocisteine), antitussive agents (glaucine hydrobromide, okseladyn). A specific vaccine prophylaxis was carry out under the threat of epidemic (pandemic) Influenza. In 2015-2016 years in Ukraine registered the following vaccines: Vaxigrip, Influvak. Opioids – a substance derived from the opium poppy, and their synthetic analogs having similar effects. Opioids have the ability to cause drug dependence and are characterized by a strong desire to use them, they also cause tachyphylaxis, which sooner or later leads to poisoning and overdose. The aim of our study was to investigate modern rational pharmacotherapy for opiate poisoning. We was study the adapted clinical guidelines based on evidence, articles, unified clinical protocols of emergency medical care and pharmacotherapy for poisoning opiates. The main symptoms of acute intoxication by opiates are dizziness, tinnitus, dry mouth, nausea, sometimes vomiting. The skin of the face and torso hyperemic or pale, sometimes puffiness of the face, itching and rash. The body temperature is reduce, skin feels wet and cold, cold extremities is observe. Pharmacotherapy of opioid addicts consists of three main phases: detoxification (mild withdrawal syndrome); somatoneurological correction of mental disorders and primary preventive treatment; supporting preventive treatment. For the relief of withdrawal symptoms using integrated circuit with psychopharmacological agents, wegetotropic drugs, muscle relaxants, painkillers, treat with prolonged medicated sleep (with the use of anesthesia: thiopental sodium, sodium hydroxybutyrate); replacement therapy with the use of narcotic analgesics and their gradual cancellation (methadone, buprenorphine programs, the legalization of soft drugs and delivery of treated persons drugs addiction), rapid opioid detoxification.
