Barbiturates used primarily as sedatives and hypnotics include: • amobarbital • butabarbital • mephobarbital • pentobarbital • phenobarbital • secobarbital discount dutasteride 0.5mg online. On the dose Low doses of barbiturates depress the sensory and motor cortex in the brain purchase 0.5 mg dutasteride with mastercard, causing drowsiness. Low doses of Pharmacodynamics barbiturates depress As sedative-hypnotics, barbiturates depress the sensory cortex of parts of the brain. Pharmacotherapeutics Barbiturates have many clinical indications, including: • daytime sedation (for short periods only, typically less than 2 weeks) • hypnotic effects for patients with insomnia • preoperative sedation and anesthesia • relief of anxiety • anticonvulsant effects. In comparison, benzo- diazepines are relatively effective and safe and, for these reasons, Warning! Cardiovascular and res- • When barbiturates are taken with acetaminophen, the risk of piratory effects include: liver toxicity increases. These drugs, which offer no special ad- • reduced rate of vantages over other sedatives, include: breathing • chloral hydrate • severe respiratory de- • eszopiclone pression. Other reactions include: • vertigo Diminishing returns • nausea and vomiting Chloral hydrate and zaleplon lose their effectiveness by the end of • diarrhea the second week. Food and Drug Administration requires that all sedative-hypnotic drugs include a warn- ing on the drug label about the risk of complex sleep-related behaviors. Complex sleep-related nonbenzo- behaviors include preparing and eating food, making phone calls, and even driving when not fully diazepines- awake, while having no memory of the event. The three main types of antianxiety drugs are benzodiazepines (discussed in a previous section), barbiturates (also discussed in a previous section), and buspirone. Buspirone is the first antianxiety drug in a class of drugs known as azaspirodecanedione derivatives. This drug’s structure and mechanism of action differ from those of other antianxiety drugs. Midbrain modulator Buspirone seems to produce various effects in the midbrain and acts as a midbrain modulator, possibly due to its high affinity for serotonin receptors. Buspirone has a slow onset, so it Pharmacotherapeutics isn’t useful for panic attacks. Patients who haven’t received benzodiazepines seem to respond better to bu- spirone. In case of panic Because of its slow onset of action, buspirone is ineffective when quick relief from anxiety is needed. Bipolar disorders, characterized by alternating periods of man- and horror that exist for ic behavior and clinical depression, are treated with lithium and at least 1 month and anticonvulsant drugs. Fluoxetine is the least likely to feeling sad, memory problems, and vivid cause this problem because of its extremely dreams, may also occur. Fluvoxamine, fluoxetine, sertraline, and paroxetine are also used to treat obses- sive-compulsive disorder. Venlafaxine is an antidepressant drug that’s chemically differ- ent from other antidepressants and has unique properties in terms of absorption and mechanism of action. Safe and sound Risks of antidepressants Adverse reactions Studies have shown a correlation between taking an antidepressant and the increased risk of suicidal behavior in young adults ages 18 to 24. They just melt in fat The extreme fat solubility of these drugs accounts for their wide distribution throughout the body, slow excretion, and long half- lives. The upside to preventing reuptake After a neurotransmitter has performed its job, several fates are possible, including rapidly reentering the neuron from which it was released (or reuptake). Preventing reuptake results in in- creased levels of these neurotransmitters in the synapses, reliev- ing depression. They’re es- pecially effective in treating depression of insidious onset accom- panied by weight loss, anorexia, or insomnia. Physical signs and symptoms may respond after 1 to 2 weeks of therapy; psychologi- cal symptoms, after 2 to 4 weeks. When given with a mood stabilizer, they may be helpful in treating acute episodes of depression in bipolar I disorder. This leaves more norepinephrine, dopamine, and sero- tonin available to the receptors, thereby relieving the symptoms of depression. For example, the pa- tient gains weight, sleeps more, and has a higher susceptibility to rejection. Other uses include treatment for: • phobic anxieties • neurodermatitis (an itchy skin disorder seen in anxious, ner- vous people) • hypochondriasis (abnormal concern about health) • refractory narcolepsy (sudden sleep attacks). The most serious reactions involve tyramine-rich foods, such as red wines, aged cheese, and fava beans. Foods with mod- erate tyramine contents—for example, yogurt and ripe bananas— may be eaten occasionally, but with care. Other antidepressants in use today include: • maprotiline and mirtazapine, tetracyclic antidepressants • bupropion, a dopamine reuptake blocking agent • venlafaxine, a serotonin-norepinephrine reuptake inhibitor • trazodone, a triazolopyridine agent • nefazodone, a phenylpiperazine agent. The drug is almost completely bound to plasma proteins and is excret- ed in urine.

It is particularly of great importance where small volumes of liquids are measured generic dutasteride 0.5mg amex. A positive evidence for a dirty apparatus may be sought by observing the adherence of droplets to the walls of a burette or pipette cheap dutasteride 0.5mg online. However, in a clean volumetric apparatus, the liquid drains down quite uniformly thereby wetting the walls so that no droplets are visible to the naked eye. A few very effective cleaning fluids that are used in good analytical laboratories are, namely : (i) Chromic Acid Mixture, (ii) Synthetic Detergent Solutions (or Alkaline Cleansing Agents), and (iii) Teepol. Chromic Acid Mixture Materials Required : Sodium dichromate : 200 g ; Sulphuric acid : 1500 ml. Procedure : Weigh 200 g sodium dichromate and transfer to a 2 Litre hard-boroslicate glass beaker. Now, add to it 1500 ml of sulphuric acid (36 N) in small bits at intervals with constant stirring. Chromic acid mixture is extremely corrosive and hygroscopic and must be stored in closed glass-stoppered bottles. Synthetic Detergent Solutions (or Alkaline Cleansing Agents) Detergents are synthetic cleansing agents used with water. The most commonly used anionic surfactants containing carboxylate ions are known as soaps which are generally prepared by the saponification of natural fatty acid glycerides in alkaline solution. Usually a 2 to 5% (w/v) solution of a good detergent powder in water serves as a reasonably effective cleansing agent. Teepol (or Gardinol Type Detergents) It is a mixture of the sodium salts of sulphated fatty alcohols made by reducing the mixed fatty acids of coconut oil or cottonseed oil, and fish oils. Sometimes natural waxes such as spermaceti, wool fat and bees wax are sulphated directly. A 1 to 3% (w/v) solution of Teepol in water may also serve as a good cleansing agent for the removal of stubborn deposits and stains present in glass apparatus. It can be accomplished by opening the stopcock of the burette in such a manner that only a fraction of a drop flows out and remains adhered to the tip of the burette. Hence, two flasks containing the same volume of solution having approximately the same composition as the liquid being titrated may be prepared; first, slightly acidic—Red solution, second, slightly basic—Yellow solution. In fact, these carefully-prepared comparison solutions would ultimately help in deciding the colour change thereby confirming the actual end-point without any controversy, whatsoever, (7) All titrations must be carried out in triplicate and the results of two concurrent readings (i. Presently, both serum and urine assays are being used extensively in diagnostic medicine which evidently signifies that the pharmacist of today should be fully conversant with the ever-increasingly important techniques of biomedical analytical chemistry. It is, however, necessary to make a passing reference to microbiological assays and haematological assays, also being carried out in a clinical laboratory, though it should not be treated under this topic since these methods are outside the scope of biomedical analytical chemistry. Later, an extensive and intensive studies revealed this to be an absolutely false diagnosis. In the same vein, such analytical and biochemical interferences with respect to drug interference in various biomedical assays are being profusely cited in current scientific and research journals, such as the American Journal of Hospital Pharmacy and Clinical Chemistry. It has been established beyond any doubt that analytical interferences can only take place when a drug or its resulting metabolite happens to interfere with the analytical method adopted for the assay. In order to have a comprehensive account on the various aspects of ‘Biomedical Analytical. Chemistry’, we may have to study the following four methods of assay with specific emphasis on their principle and applications, namely : (a) Colorimetric Assays, (b) Enzymatic Assays, (c) Radioimmunoassays, and (d) Automated Methods of Clinical Analysis. Theory : In fact, two fundamental laws actually govern the practice of colorimeteric assays of photometry. First Law : Bougner’s (1729) or Lambert’s (1760) Law defines that—“when a beam of monochromatic light, previously rendered plane-parallel, enters an absorbing medium at right angles to the plane-parallel surfaces of the medium, the rate of decrease in radiant power with the length of light path through the absorbing medium`b’ is directly proportional to the radiant power of the beam, i. Alternatively, it may be explained that if a particular thickness absorbs half the light, the thickness which follows the first half and is equal to it will not absorb the entire second half, but instead only half of this half and will consequently reduce it to one-quarter. Molar Absorptivity (∈) : It is the product of the molecular weight of the substance and its absorptivity and is designated by the symbol ∈. Beer’s Law (or Beer-Lambert’s Law) : The combined law is invariably referred to as ‘Beer’s Law’, while some texts refer to this as ‘Beer-Lambert’s Law’. Beer’s Plot : It is a plot of the absorbance value (along Y-axis) against a series of unknown solute concentrations in g/litre (along X-axis) thereby yielding a straight line passing through the origin. Therefore, the solute-concentration present in an unknown solution can be estimated conveniently from the Beer’s Plot or sometimes referred to as the Standard Curve, merely by measuring the absorbance value of the solution and then finding the concentration value that corresponds to the measured absorbance value as is illustrated in the following Figure 2. The colorimetric assay of sulphadiazine is based on theacid-catalysed equilibrium reaction that occurs between vanillin (an aldehyde) and sulphadiazine (an arylamine). The chemical species that forms as shown below is known as the Schiff’s Base and is yellow in colour. The relationship between per cent transmittance and concentration is shown in Figure 2.

Upon administration of particle suspension to the eye cheap 0.5 mg dutasteride with mastercard, the particles reside at the delivery site (cul-de-sac discount dutasteride 0.5 mg without a prescription, sub conjunctiva or vitreous humor) and the drug is released from the particles through diffusion, chemical reaction, polymer degradation, or ion-exchange mechanism, resulting in increased ocular absorption. Piloplex was one of the first commercial exploration of nanoparticle formulations in ocular drug delivery. The formulation consists of pilocarpine-loaded nanospheres of poly(methylmethacrylate-acrylic acid) copolymer. Following this introduction, many nanoparticle systems have been investigated for the prolongation of contact time in order to increase the ocular absorption. A significant reduction in intra- ocular pressure was noted following administration of betaxolol-poly- ε caprolactone nanoparticles, compared to the commercial eyedrops. The enhancement was ascribed to two factors: one because the nanoparticles increased the precorneal retention of the drug by agglomeration; and secondly because the entrapped drug was in the non-ionized form in the oily core of the carrier and could diffuse at a great rate into the cornea. Similar improvements were obtained with carteolol (β-blocker) which induced a better penetration of the drug from the nanosphere formulation. Liposomes Liposomes can be defined as microscopic vesicles, composed of membrane-like lipid bilayers surrounding aqueous compartments (see Section 5. Phospholipids commonly used in the preparation of liposomes are phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, phosphatidic acid, sphingomyelin, cardiolipins and cerebrosides. The versatility in manufacturing and use of liposomes is attributed to their amphiphilic nature. Both hydrophilic and lipophilic drugs can be encapsulated within the lipid vesicles. It has been shown that drugs with very low or very high logP values exhibit prolonged liposomal retention. The first application of liposomes in ocular drug delivery involved the application of a 312 liposomal suspension of idoxuridine to rabbits for the treatment of herpes simplex keratitis. The liposmal formulation was found to be more efficient results compared to the aqueous solution. Liposomes can be easily prepared from non-toxic materials, which are non-irritant and do not obscure vision. Unfortunately, routine use of liposomes in topical ocular drug delivery is presently limited by short shelf life of the formulation, limited drug loading capacity and obstacles in sterilizing the preparation. Emulsions Emulsions have been used for centuries for the oral administration of medical oils and vitamins and as dermatological vehicles. Recently, their application has been extended as drug carriers in the delivery and targeting of ophthalmic drugs. An indomethacin emulsion has been reported to increase ocular bioavailability and efficacy compared to commercially available formulation in rabbits. The emulsion formulation also reduced ocular surface irritation caused by indomethacin. Similar advantages have been shown for a pilocarpine emulsion which produced a prolonged therapeutic effect in comparison with pilocarpine hydrochloride eyedrops in man. It can be administered only twice a day, rather than four times daily for conventional formulation. Other ophthalmic emulsions have been used to formulate prednisolone, piroxicam and amphotericin B emulsion. Although emulsions can produce sustained therapeutic effects and reduced irritancy of drug, their application in ophthalmology have been limited due to problems of stability. Soft contact lenses and ocular inserts The rationale for corneal contact devices has not been fully explored in therapy. In conventional dosing, there is a gradient across the eye caused by lacrimal flow, opposing drag of material above the equatorial axis by the upper lid as illustrated in Figure 12. Thus it is difficult to sustain high drug concentrations in the upper hemisphere unless the eye is bathed or the patient is supine. A corneal device such as a collagen shield or contact lens overcomes this problem by providing a slowly equilibrating reservoir. It is generally accepted that soft contact lenses can act as a reservoir for drugs, providing improved release of the therapeutic agent. The therapeutic value of contact lenses was first demonstrated in a study which showed a significant increase in aqueous humor levels produced by drug-soaked lenses when compared with the conventional eyedrop. The use of Bionite contact lenses for delivery of idoxuridine, polymyxin B and Pilocarpine also showed that instillation of a drug solution onto an unmedicated contact lens was significantly more effective than instillation of a more concentrated drug solution directly to the cornea. However, the soaking of lenses in ophthalmic formulations to incorporate the drug into the lens may cause toxicity to corneal epithelium because preservatives, such as benzalkonium chloride, have a great affinity for the hydrophilic contact lens material and are concentrated in the contact lens. Contact lens for sensitive wearers may also cause foreign-body sensation, blurring and decreased oxygen tension on the corneal surface resulting from occlusion by contact lens. An alternative system, manufactured as a wafer-like insoluble implant, has been developed (Ocusert). The system is preprogrammed to release pilocarpine at a constant rate of 20 or 40 μg/hr for a week to treat chronic glaucoma; however, release from inserts may be incomplete and approximately 20% of all patients treated with the Ocusert lose the device without being aware of the loss.

Red sponge with clay contains French red clay purchase 0.5mg dutasteride otc, thanks to the properties of which it further helps to even out skin tone order 0.5 mg dutasteride amex, moisturize it and even prevent wrinkles due to soft massage action. In dry form by its hardness the sponge resembles a piece of stone, but being wet, it becomes soft, jelly-like, and very pleasant to the touch. Unlike other sponges for the face, it is not just cleaning, but also has excellent exfoliating action, as well as helping to strengthen the properties of a cleaning agent and cleans the pores. Konjac sponge contributes to liquid penetration to the upper layers of the epidermis, thus moisturizing and making the skin more elastic. Therefore, we can conclude that the konjac sponge due to its consumer properties, exhibits good effect and is suitable for various skin types, at its use there is also no need to the additional use of other cosmetic products. No one denies about the benefits breast milk for feeding a small child, but and there are times when a baby at birth or later have to bring up with artificial milk mixes. However, even the most advanced milk mixes cannot be compared with breast milk, which composition provides optimum flow for the individual child, not only nutritious, but also many other substances and cells: white blood cells, antibodies, enzymes, hormones, etc. According to medical statistics, only 1-3% of women have serious health problems that make it impossible to breastfeeding, while 60% of children from birth to 2 months transferred to artificial feeding. The reason for this is the failure or ignorance of basic rules of breastfeeding baby. To date, this type of baby food (infant mix) presented a wide range of assortment of products of different companies, types, storage, price ranges etc. Aim of our research was to streamline the classification and study of the range of dry milk mixes that are present on the market of Ukraine. During our research were analyzed modern national and foreign literature on the existing of classification and characteristics of dry milk mixes for children. Also, there were used methods of semantic analysis and hierarchical classification. Today on the national market are represented dry milk mixes for children made by such manufacturers as America, France, Holland, Germany, England, Finland, Sweden, Austria, Japan, Israel, Yugoslavia, Switzerland, India and Ukraine. But unfortunately, that among all the product range of baby food Ukrainian milk mixes presented only a few names. Today there is modern classification of dry milk mixes: ● Highly adapted infant mixes. The composition of such mires are the following ingredients: whey, taurine, choline, lecithin, inositol. Lactose-free and low-lactose mixes for children with reduced activity of the enzyme lactase in the intestine, lactose intolerance («Nutrilon low-lactose» «Similak-izomil»); 2. In a result of the above we can conclude that the best food for the baby at all times been and remains breast milk. However, the choice of mix - this is a very important matter, which depends largely on the health of the child not only in the present but in the future, because that child did not receive an early age, it is impossible to be offset in the future. Therefore, we must always remember that before you give your child a substitute for breast milk, consult with your pediatrician first, and then with pharmacist! For the disinfection of medical instrument are used different techniques, including chemical methods. The advantage lies in its simplicity, reliability and availability, and is the main disadvantage of solutions aggressive towards metal medical materials. The purpose of research - a comparative evaluation of corrosiveness of modern disinfectants to metal tools. Disadvantages: chlorine compounds are toxic, have a pungent smell, stable solutions in wastewater does not decompose, are corrosive materials. Iodine has a broad spectrum of antimicrobial activity, but has no effect on bacterial spores. Preparations based on iodine are corrosive to metals, rubber and degrade the quality of some plastics. All alcohols have a broad antimicrobial spectrum (except spores), evaporate quickly, and after evaporation leaves no residue. Alcohols are used as part of antiseptics, agents for the treatment of external surfaces of some equipment (eg, for stethoscopes). They have a broad-spectrum activity, including contra of spore forms of bacteria, to allow the use of this group of tools for sterilization. Further studies will be used to optimize the quantitative and qualitative characteristics of the composition of the solution containing the active peroxide groups. As a result of this work we define the criteria according to which optimization will be performed compositions of disinfectant solutions based on peroxides. The optimal composition must be different maximum rates sporicidal activity, reagent stability ability, the minimum processing time and minimal corrosive effect on tool materials.

Of particular importance is the formation of motivational readiness for professional work of future specialists of a medical profile generic 0.5mg dutasteride fast delivery. This motivational readiness to professional activity will be a key element in the training of highly qualified specialist discount 0.5 mg dutasteride with visa, provide him with rapid adaptation in health care facilities, career opportunities, a desire to engage in research work, take an active part in the life of society. The main contemporary goal of high medical education is the personality and it‘s abilities orientation. It updates the introduction of personally focused education at the training of physicians. To ground a pedagogics of personally focused education to the teaching discipline "Psychiatry and Narcology. There was used a complex of methods consisted of theoretical (a generalization of the scientific literature, the rationale of personally focused education) and empirical (questionnaires, interviews to explore the subjective experience of students; direct and indirect observation) ones. Yakimanskaya‘s viewpoint that the main function of education is to discover personality and to create conditions for it‘s development on the base of subjective individual experience, ensuring the formation of criticality, independency, initiativity, creativity and their implementation into ideation and behavior. The results of the survey of university teachers of Psychiatry and Narcology department show that the scientific and pedagogical staff is aware of contradictions between traditional and personally oriented education. The study of the responses at the survey and interviews revealed that the result of traditional teaching style is formalization of the relationship between students and teachers. In case of personally oriented education open relations between the subjects of study are possible together with an individual accounting of cognition, values and personal experience of the student. To make a personally oriented environment the departmental staff ellaborated some didactic complex for the "Psychiatry and Narcology" discipline. To ensure professionally significant motivation of the students by using the portfolio analysis we identified individual characteristics and the main features of subjective experience. Students were informed beforehand concerning necessity to create a portfolio (either printed or electronic form) during the first lesson. Implementation of portfolio to the education is provided an opportunity for teachers to realize the developmental level and abilities of student in ongoing 371 preparation of doctors of somatic profile. It also helps to outline future directions of incentives, to contribute quality of training improvement, to revitalize medical care to patients with mental disorders. We have accepted the statements of some scientists about the importance of personally oriented training to the educational process (in particular, the playing, the dialog). For example, an interactive teaching method was implemented during the binary lecture on the theme "Medical and social problems of psychoactive drug abuse. Game method of learning was implemented during the practical training in mental disorders as well as in independent work on the theme "History of Psychiatry Development and Addiction". Person-oriented nature of the practical lesson "Reaction to severe stress and adjustment disorders. Post-traumatic stress disorder" was granted thanks to the introduction of elements of training. Ukrainian researchers note that academic training is an intensive form of group work where the emphasis is not so much for the information how to receive personal experience of professional activities. Thanks to the introduction of elements of the training the students received the opportunity to become familiar with the peculiarities of using art-therapy methods for the accumulation of resources by the survivors of traumatic events. Analysis of literature and teaching experience allow to identify the main pedagogical conditions of introduction of person-oriented education in teaching discipline "Psychiatry and Narcology". The pedagogical conditions includes the creation of personality-oriented environment in the educational space of the university, the use of student-centered teaching methods, ensuring internal professionally significant motivation of the students during the study of the discipline. The questions of improvement of the health system in Ukraine according to market requirements have gained great importance at the present stage of development of Ukraine. It is possible to prepare such a specialist providing an appropriate learning environment which would include a system of independent study. Give haracteristics to different types, forms and methods of independent study in the discipline "Fundamentals of Economic Theory" at a Medical College. To solve the given problems we applied theoretical and empirical methods such as observation and discussion. Theoretical analysis of the term "independent students study" allows to consider it master educational material. Independent learning as a didactic form of teaching includes the following organization stages: planning, organization process and supervision; effective control and assessment. Our experience shows that the teacher should provide a variety of types, forms and methods of independent work of students for effective learning in the sphere of economics at a Medical College. Implementation of innovative teaching methods allows to carry out part-investigative, creative and research work in the classroom and extracurriculum independent students work. Planning of independent students work in the discipline "Fundamentals of Economic Theory" also includs group and individual students work. Organizing extracurricular work of students we tried to establish interaction between the participants of educational process. Consultations and different support that teachers give to their students create the atmosphere of cooperation between them. Analysis of pedagogical sources of literature allows to mention different methods and techniques which help to develop critical thinking among them 373 there is case method, methods of clusters, mental maps, digests and method of project.
