For the diagnosis of onychomycosis used bacterioscopic and bacteriological methods mellaril 50mg otc. Modern pharmacotherapy for onychomycosis includes systemic and topical antifungal therapy mellaril 100 mg amex. Topical therapy may only be apply in case of damage of less than 30% of the nail plate in the absence or low hyperkeratosis generic mellaril 10 mg amex, contraindications to systemic therapy. Local antifungal therapy include using of keratolytics for lysis of the affected nail plate from the nail bed, followed by treatment antifungals for topical use. There form of drugs for the topical application are lacquer, cream, ointment, containing ketoconazole, terbinafine, oxiconazole, miconazole, and undecylenic acid. Systemic antifungal therapy is required to shown at the defeat of more than 50% of the nail plate, a 2-3 defeat of the nail plate, nail plate pronounced changes (hyperkeratosis, onycholysis), the defeat of the nail matrix. Among the antifungal drugs for systemic use recommended ketoconazole, itraconazole, fluconazole, terbinafine. Duration of pharmacotherapy is determined by the severity and nature of the disease, the average course of treatment is 6-12 weeks, sometimes more. Itraconazole administered 200 mg two times a day for 7 days and after 3 weeks of rest. It recommended in the defeat nail plates hands – 2 courses, nail plates feet – 3 courses of pulse therapy. Modern pharmacotherapy for onychomycosis includes combination topical and systemic antifungal drugs. System reaction to stress, which is aimed at eliminating or mitigating negative effects, is accompanied by changes in behavior, autonomic, motor, sensory and other body functions. Behavior stress is an integral part of the overall behavior, thus changing behavioral reactions leads to inhibition of the central nervous system. The purpose of this work was to study the effect of oligopeptides derivatives on behavioral responses of rats in the "open field" test. Investigated substances were administered orally in the form of aqueous solutions in doses of 70 and 100 mg/kg in 60 minutes before the experiment start. The animals of control group were injected with the corresponding volume of saline. The study found that the number of crossed squares was significantly increased after the administration of compound 2 at a dose of 70 mg/kg by 72. The administration of the compounds was affected to the number of explored holes as follows: compound 1 at a dose of 100 mg/kg, compound 2 at a dose of 70 mg/kg, compound 5 at a dose of 100 mg/kg increased the index by 88. During the study it was found that the greatest influence on the behavior of rats, such as psycho-stimulant activity, showed the compound 6 which increased the number of crossed squares in 2 times at a dose of 100 mg / kg, the number of vertical racks in 1,7 times, and the number of explored holes in 1. The administration of the same compound at a dose of 70 mg/kg influenced the behavior of experimental animals such as the number of crossed squares increased by 64. Among the seven oligopeptides derivatives all substances are characterized by psycho-stimulant activity at a dose of 100 mg/kg. Cough – a natural reflex defensive reaction that occurs in response to any irritation airway inflammation or something that prevents the passage of air for pneumatic paths. Despite the fact that the cough reflex is natural in our body which main function - cleansing the respiratory tract and restore their patency, severe cough can significantly reduce the quality of life of any person. Drug for the treatment of cough should be safe and highly effective to the patient in a very short time deprived of this disease. Ledum palustre - evergreen shrub heather family (Ericaceae), which includes essential oil (1. In modern medical practice, Ledum palustre is used as an antitussive and expectorant. We have been set up an experiment- cough model in rats induced with citric acid in the vivarium at the Institute of Microbiology and Immunology I. The experiment involved rats weighing 200-250 g rat was placed in a box, which has been connecting to the nebuliser and inhaled citric acid 10% for 5 minutes. In the first stage the animals individually tested for reaction intensity citric acid per day prior to administration of the test substance. The experience collected intense coughing rats (15-25 cough attacks within 30 minutes). In the second step (the next day) experienced reference drug codeine (20 mg / kg) which was administered orally through a metal probe 60 minutes before the inhalation of 10% citric acid for 5 minutes. The study gave a positive result- after the introduction of caffeine coughing attacks decreased on 79%. The stated cough model makes it possible to study the antitussive activity and dose dependence of extracts Ledum palustre. To reset the rhythm to sinus rhythm using cardioversion, which can be conduct in two ways: electrical cardioversion or cardioversion with drugs. In cardioversion with drugs uses anti-arrhythmics medications: dofetilide, flecainide, propafenone, amiodarone, sotalol. Heart rate control can be achiev through several medications: digoxin may control heart rate at rest, but not as well during activity. Most people require additional or alternative medications, such as beta blockers (metoprolol and atenolol), calcium channel blockers (diltiazem and verapamil). Most people with atrial fibrillation are at especially high risk of blood clots that can lead to stroke. To prevent blood clots recommended anticoagulants: warfarin, dabigatran, rivaroxaban. With this approach, the abnormal heart rhythm continues, but you feel better and have fewer symptoms.

Such pumps were finally developed in the early 1980s and they allow physicians and patients to precisely control the infusion rate of a drug 25mg mellaril mastercard. Most implantable pumps are made of titanium which has proven records of excellent biocompatibility and long life 10mg mellaril for sale. They are usually implanted intraperitoneally order mellaril 100 mg, in a pocket created in the abdominal wall of patients, under the subcutaneous fat layers, but above the muscular fascias. They are secured to the muscular fascia by suturing, which prevents pumps from flipping over or migrating in the pump pocket, thereby allowing patients to resume routine physical activities. Intraperitoneal insulin pump therapy is advantageous over a subcutaneous injection, as insulin infused into the peritoneal membrane surrounding abdominal organs is absorbed faster and more completely than via subcutaneous injection. Arterial or intraspinal delivery is also possible with a proper surgical procedure. A silicone rubber catheter is attached to the pumps, through which infusate is delivered to various body sites. The catheter is replaced if it becomes blocked, for example, by the deposition of infusate inside the lumen, fibrous tissue encapsulation or clotting at the tip. The major components are a miniature peristaltic pump, a drug reservoir (18 ml), a battery, an antenna, a microprocessor and a catheter through which infusate is delivered to a specific site. The infusion rate of a drug solution can be programmed by a portable computer with specialized software which transmits instructions by radiotelemetry to the pump. The pump is driven by a step motor, controlled by signals from the micropocessor and is capable of delivering infusate at varying rates (0. The programmer provides the implantable pump with versatile delivery patterns, including a straight continuous-flow pattern or a more complex pattern that allows a varying dose at different times of the day to meet the patient’s changing metabolic requirements. The SynchroMed pump is approved for use in: • chemotherapy (using floxuridine, doxorubicin, cisplatin, or methotrexate); • the treatment of chronic, intractable cancer pain (using morphine sulfate); • osteomyelitis treatment (using clindamycin); • spasticity therapy (using the muscle relaxant, baclofen). The pressure of the roller heads on the tubing in the peristaltic pump causes intensive shear stresses which lead to stability problems for labile peptides and proteins. A patented solenoid motor controls the piston movement, to aspirate insulin from the reservoir chamber into the piston chamber and then push it through the insulin delivery catheter. A hand-held programmer can change the pumping rate to administer the desired insulin dose to the diabetic patient. Many conventional insulin preparations are prone to denaturation when exposed to body fluids and temperature, or when agitated (see Section 1. The ensuing aggregation and precipitation may cause blockage of the catheter attached to the pump. However, the Minimed pump uses an insulin formulation, developed by Hoechst, which includes a small amount of Genapol (polyethylene glycol and polypropylene glycol), to increase the stability of the polypeptide. Infusate is placed in the inner drug reservoir chamber and Freon propellant in the outer chamber (Figure 4. When the Arrow pump is implanted subcutaneously, it is warmed by the patient’s body temperature so that the propellant-containing chamber expands and exerts pressure on the movable bellows. Infusate is thus forced out of the reservoir chamber to an attached catheter through a filter and flow restrictor. This mechanism allows the delivery of infusate at a fairly constant rate to surrounding tissues or blood vessels. It should be noted, however, that the vapour pressure exerted by the outer chamber can be affected by changes in altitude/elevation or body temperature. The Infusaid pump is another fixed-rate implantable pump that shares many similar features, including the Freon pumping principle, with the Arrow pump. Indeed, there now exists bio-responsive implantable systems, and implants for gene therapy; such advances are described in Chapter 16 (New Generation Technologies). However, despite the striking advances in this field, implantable systems will always be limited by the invasive nature of this therapy. A company is trying to develop a reservoir-type polymeric implant for the controlled release of estradiol for 3 months. Which techniques would you recommend to the company to increase the drug release rate? A new steroidal drug is allowed to pass through a siloxane membrane (surface area=23. Provided that the drug release rate is constant, calculate the flux (F) that is defined as the amount of a solute flowing through a membrane per unit time. The release rate of a drug from conventional non-degradable matrix-type polymeric implant usually decreases over time. What is the main reason for developing a reservoir/matrix hybrid-type polymeric implant? Which polymer is most extensively used as non-degradable nonporous membrane to develop reservoir-type polymeric implants? Which of the following is/are an example(s) of non-biodegradable matrix-type implant? What is the principle that has been utilized in the development of the Alzet and the Duros implant pumps in which a drug solution or suspension is confined in a semi-permeable membrane that allows only water molecules to move through it? The release rate (dM/dt) of a drug from an osmotic pump can be described as C (dV/dt)d where Cd is the drug solubility in its reservoir compartment. The effective surface area, permeability coefficient, thickness, and osmotic reflection coefficient of the semi-permeable membrane used for the pump are 3. If we change the reservoir medium and osmotic agent to increase C ofd the drug from 100 to 300 mg/ml and to increase ∆π from 100 to 300 atm, by how much will the release rate of the drug increase? The most important routes of injection of these sterile products are intramuscular (im), intravenous (iv) and subcutaneous (sc). The detailed description of 106 these areas of pharmaceutics lie outside the remit of this text and the reader is refered to information provided in the further reading section of Chapter 1. This chapter focuses on advanced drug delivery and targeting systems administered via the parenteral route and serves to provide the reader with a basic understanding of the principal approaches to drug targeting.

In the past trusted mellaril 100 mg, the oral or intravenous dose of phylloquinone used to counteract supratherapeutic anticoagulation was 10–50 mg (Fetrow et al discount 100mg mellaril otc. In asymptomatic patients discount mellaril 25 mg line, a 1-mg oral dose of vitamin K was shown to reduce the international normalized ratio effectively (Crowther et al. Low subcutaneous doses of phylloquinone are an effective alternative to intravenous administration of phylloquinone in the treatment of warfarin-induced hypoprothrombinaemia (Fetrow et al. A first meta-analysis of the trials came to the conclusion, however, that it is ineffective (Thorp et al. Commercially significant forms are menadione sodium bisulfite and mena- dione dimethyl pyrimidinol (Van Arnum, 1998). Menaquinone-4 has been used in Japan at high doses for the treatment of osteo- porosis (Shearer, 1997). It is present in many foods, especially leafy green vegetables and some vegetable oils. Intakes are estimated from the concentrations of individual nutrients and contaminants in the core foods and the mean consumption of the foods in each population group. The quantitative contributions of specific foods to the phyllo- quinone intake of the total population are presented in Table 3. Table 4 gives the esti- mated daily intake in 1990 for 14 categories of age and sex (Booth et al. Phylloquinone has been determined by several analytical methods in human milk, in cow’s milk, in many brands of infant formula and in the oils that have been added to infant formulas for many years. Some of the concentrations found in each of these sources are presented in Table 1. They have a more restricted distribu- tion in the diet than phylloquinone, and nutritionally significant amounts probably occur only in animal liver and some fermented foods, including cheese. Menaquinones are also synthesized by specific inhabitants of the human gut microflora. It seems likely that menaquinones synthesized by the gut microflora make a significant contribution to human tissue stores and are used by the hepatic vitamin K- dependent carboxylase, but the extent of this contribution remains uncertain (Shearer, 1995; Suttie, 1995). The phylloquinone content of oil-based preparations varies widely depending on the source of the oil used. Studies of Cancer in Humans The association between childhood cancer and vitamin K administered during the perinatal period with a view to preventing haemorrhagic disease of the newborn has been investigated in a number of studies (summarized in Table 5). The prophylactic use of vitamin K in newborns has varied with time, geographical location and among hospitals within countries. Some hospitals during some periods have had a selective policy based on the indications low birth weight, prematurity and operative delivery. The 33 cases included in the study were in patients who had died from cancer or were identified through cancer registration as having a cancer diagnosed before the age of 10. An unexpected statistically significant association was found between childhood cancer and administration of any drug during the first week of life (Golding et al. Within the cohort, a comparison was made between the 33 cases and 99 controls matched with the cases for the age of the mother at the time of the birth of the child, parity, social class, marital status at delivery and whether the birth was single or multiple. Statistically significant associations were identified not only with drug admin- istration during the first week of life, but also with antenatal X-rays, antenatal smoking, non-term delivery and use of pethidine or pethilorfan (a pethidine-containing drug) during labour. Only two of the 33 cases had fewer than two of these risk factors, whereas Table 5. All but four of the mothers of the 16 cases who had received vitamin K had received pethidine or pethi- lorfan during labour. In a logistic regression analysis carried out on the whole cohort, in which social class was included with the other variables already mentioned, the relative risk associated with drug administration during the first week of life was 2. This combination is justified because the plasma concentrations after intramuscular administration are more than 10 times higher than those after oral administration (McNinch et al. The cases were ascertained from the oncology register of the regional paediatric oncology unit and from the National Registry of Children’s Tumours. The basic method of control selection was to select every 300th birth in each year in each hospital. In view of the observation that the immediate effects of identical oral and intra- muscular doses of vitamin K are different, the investigators sought to distinguish the effects of administration by the two routes. On the basis of 180 cases (92% of those for which notes were available) and 544 controls (98% of those for which notes were available), the relative risk (adjusted for hospital and year of delivery) for childhood cancer associated with intramuscular vitamin K was 2. In view of the absence of an association with oral vitamin K in these data, the authors conducted a subsequent analysis in which the reference group was defined to include infants who had not received vitamin K or who had received it orally. Thus, there was no clear difference in the association by type of childhood cancer. When the analysis was confined to records in which the route was clearly stated, the odds ratio for all childhood cancer was 2. These results could not be accounted for by other factors associated with the administration of intramuscular vitamin K, such as type of delivery or admission to a special care unit. Data were collected on 319 variables for all controls and for 111 cases of cancer ascertained from the oncology register of the regional paediatric oncology unit; these data were not obtained for the remaining 84 cancer cases. Of these variables, the presence of rubella antibody, resusci- tation by intermittent positive pressure and paediatric estimate of gestation were statis- tically significant at the 1% level, which is what would be expected by chance. Adjust- ment for these and other variables reported to be associated with childhood cancer or known to be indicators for administering intramuscular vitamin K had little effect on the odds ratio for childhood cancer associated with vitamin K. Nineteen of the cases were diagnosed in the first year of life, and the possibility was considered that these cancers might have been present before the child was born and could therefore not have been initiated by an injection of vitamin K; however, the association persisted after exclusion of these 19 cases from the analysis. When the analysis was restricted to subjects who would have been followed for at least 10 years, by considering only those born in the period 1971–80, the relative risk for all childhood cancer associated with intramuscular vitamin K was 1. Medical records are not necessarily reliable sources of information about pregnancy and childbirth (Hewson & Bennett, 1987; Oakley et al. The relationship between the type of delivery and intramuscular administration of vitamin K differed markedly between the two maternity hospitals in Bristol in which the case and control subjects in the study had been born (Carstensen, 1992; Draper & Stiller, 1992).
