Drugs such as digoxin and warfarin with a long half-life will take longer to reach a steady state than drugs with a shorter half-life order atarax 25mg without a prescription anxiety symptoms over 100. To be effective discount 25 mg atarax fast delivery anxiety symptoms home remedies, the drug must reach a certain level and so must the water in the bucket cheap 25mg atarax otc anxiety 800 numbers, but the body is not a closed system – drug is constantly being lost cheap atarax 25 mg anxiety symptoms from work. This loss of drug from the body can be represented by putting a small hole in the bucket so that some water is constantly leaking out. Like the drug level in the body, the level of water drops and needs to be topped up by giving regular doses. Pharmacodynamics Pharmacodynamics is the study of the mode of action of drugs – how they exert their effect. There are receptors found on cell membranes or within a cell which natural hormones and neurotransmitters can bind to and cause a specific effect. Drugs can bind to these sites in ways that either cause an effect (agonists) or block an effect (antagonists). A partial agonist does not produce a full effect – if there is a high concentration of partial agonists, they may bind to a receptor site without producing an effect. However, in doing so, they may block that receptor to other agonists and so act as an antagonist – so partial agonists have a ‘dual’ action. One action of histamine is to stimulate 130 Action and administration of medicines gastric secretion. Ranitidine can block the action of histamine, reducing gastric acid secretion by about 70 per cent. Another way in which drugs can act by interfering with cell processes is by affecting enzymes – enzymes can promote or accelerate biochemical reactions and the action of a drug depends upon the role of the enzyme it affects. For example, uric acid is produced by the enzyme xanthine oxidase, which is inhibited by allopurinol. High levels of uric acid can produce symptoms of gout and allopurinol works by reducing the synthesis of uric acid. For example, thiazide diuretics reduce the reabsorption of sodium by the kidney tubules, resulting in an increased excretion of sodium and hence water. Cancer drugs act by interfering with cell growth and division; antibiotics act by interfering with the cell processes of invading bacteria and other micro-organisms. We will look at two of the most common routes of administration: oral and parenteral. Administration of medicines 131 Oral administration For most patients, the oral route is the most convenient and acceptable method of taking medicines. Drugs may be given as tablets, capsules or liquids; other means include buccal or sublingual administration. The disadvantages are that: • absorption can be variable due to: • presence of food; • interactions; • gastric emptying; • there is a risk of ‘first-pass’ metabolism; • there is a need to remember to take doses. As mentioned before, a major disadvantage of the oral route is that drugs can undergo ‘first-pass’ metabolism; taking medicines by the sublingual or buccal route avoids this as the medicines enter directly into the bloodstream through the oral mucosa. With sublingual administration the drug is put under the tongue where it dissolves in salivary secretions; with buccal administration the drug is placed between the gum and the mucous membrane of the cheek. If viewed from above, the level may appear higher than it really is; if viewed from below, it appears lower. Oral syringes are available in various sizes, an example are the Baxa Exacta-Med® range. Oral syringe calibrations You should use the most appropriate syringe for your dose, and calculate doses according to the syringe graduations. However, there are concerns with this ‘dead space’ when administering small doses and to babies; the ‘dead space’ has a greater volume that that for syringes meant for parenteral use. If a baby is allowed to suck on an oral syringe, then there is a danger that the baby will suck all the medicine out of the syringe (including the amount contained in the ‘dead space’) and may inadvertently take too much. A part of the oral syringe design is that it should not be possible to attach a needle to the nozzle of the syringe. Remember, from the section on pharmacokinetics, the elimination half-life is the time taken for the concentration or level of a drug in the blood or plasma to fall to half its original value. Drugs with very short half-lives disappear from the bloodstream very quickly and may need to be administered by a continuous infusion to maintain a clinical effect. Methods of intravenous administration Intravenous bolus This is the administration of a small volume (usually up to 10mL) into a cannula or the injection site of an administration set – over 3–5 minutes unless otherwise specified. Intermittent intravenous infusion This is the administration of a small volume infusion (usually up to 250mL) over a given time (usually 20 minutes to 2 hours), either as a one-off dose or repeated at specific time intervals. It is often a compromise between a bolus injection and continuous infusion in that it can achieve high plasma concentrations rapidly to ensure clinical efficacy and yet reduce the risk of adverse reactions associated with rapid administration. Continuous intravenous infusion This is the administration of a larger volume (usually between 500mL and 3 litres) over a number of hours. Continuous infusions are usually used to replace fluids and to correct electrolyte imbalances. Indications for use of intermittent infusions are: • when a drug must be diluted in a volume of fluid larger than is practical for a bolus injection; • when plasma levels need to be higher than those that can be achieved by continuous infusion; • when a faster response is required than can be achieved by a continuous infusion; • when a drug would be unstable when given as a continuous infusion. Indications for use of continuous infusions are: • when a constant therapeutic effect is required or to maintain adequate plasma concentrations; • when a medicine has a rapid elimination rate or short half-life and therefore can have an effect only if given continuously. Drawbacks to use of intermittent or continuous infusions are: • volume of diluent may cause fluid overload in susceptible patients, e. Subcutaneous injections are usually given into the fatty layer directly below the skin; absorption is greater when compared with the oral route as the drug will be absorbed via the capillaries. The disadvantages are that: • injection can be painful; • self-administration is difficult; • complications can arise, e. Practical aspects As with oral syringes, syringes for parenteral use are available in various sizes. Once again, you should use the most appropriate syringe for your dose, and calculate doses according to the syringe. For example: 136 Action and administration of medicines Intravenous Intramuscular Oral Time Fig 9. When measuring a volume with a syringe, it is important to expel all the air first before adjusting to the final volume. You should not try to administer the small amount of liquid that is left in the nozzle of the syringe after administering the drug – ‘dead space’ or ‘dead volume’. However, there are concerns with this ‘dead space’ when administering small doses and to babies, particularly if the dose is diluted before administration. However, when a diluent is drawn up into the syringe for dilution, the drug in the dead space is also drawn up, and this results in possible overdosing. Evidence indicates that the incidence of errors in prescribing, preparing and administering injectable medicines is higher than for other forms of medicine.
It is very soluble in water and in alcohol cheap atarax 25mg visa anxiety symptoms all day; it is insoluble in chloroform and is very slightly soluble in acetone buy atarax 10 mg otc anxiety treatment without medication. Naturally occurring glucocorticoids (hydrocortisone and cortisone) cheap 10mg atarax fast delivery anxiety symptoms ear ringing, which also have salt‐retaining properties buy atarax 10 mg online anxiety symptoms for dogs, are used as replacement therapy in adrenocortical deficiency states. Their synthetic analogs are primarily used for their potent anti‐inflammatory effects in disorders of many organ systems. Methylprednisolone is a potent anti‐inflammatory steroid synthesized in the Research Laboratories of The Upjohn Company. It has a greater anti‐ inflammatory potency than prednisolone and even less tendency than prednisolone to induce sodium and water retention. Methylprednisolone sodium succinate has the same metabolic and anti‐inflammatory actions as methylprednisolone. When given parenterally and in equimolar quantities, the two compounds are equivalent in biologic activity. The relative potency of Solu‐Medrol Sterile Powder and hydrocortisone sodium succinate, as indicated by depression of eosinophil count, following intravenous administration, is at least four to one. This is in good agreement with the relative oral potency of methylprednisolone and hydrocortisone. Note that convulsions have been reported with concurrent use of methylprednisolone and cyclosporin. Drugs that induce hepatic enzymes such as phenobarbital, phenytoin and rifampin may increase the clearance of methylprednisolone and may require increases in methylprednisolone dose to achieve the desired response. Drugs such as troleandomycin and ketoconazole may inhibit the metabolism of methylprednisolone and thus decrease its clearance. Therefore, the dose of methylprednisolone should be titrated to avoid steroid toxicity. This could lead to decreased salicylate serum levels or increase the risk of salicylate toxicity when methylprednisolone is withdrawn. Aspirin should be used cautiously in conjunction with corticosteroids in patients suffering from hypoprothrombinemia. There are reports of enhanced as well as diminished effects of anticoagulant when given concurrently with corticosteroids. Therefore, coagulation indices should be monitored to maintain the desired anticoagulant effect. Dosage and Administration: When high dose therapy is desired, the recommended dose of Solu‐Medrol Sterile Powder is 30 mg/kg administered intravenously over at least 30 minutes. Although adverse effects associated with high dose short‐term corticoid therapy are uncommon, peptic ulceration may occur. In other indications initial dosage will vary from 10 to 40 mg of methylprednisolone depending on the clinical problem being treated. The larger doses may be required for short‐term management of severe, acute conditions. The initial dose usually should be given intravenously over a period of several minutes. Dosage may be reduced for infants and children but should be governed more by the severity of the condition and response of the patient than by age or size. Dosage must be decreased or discontinued gradually when the drug has been administered for more than a few days. If a period of spontaneous remission occurs in a chronic condition, treatment should be discontinued. Routine laboratory studies, such as urinalysis, two‐hour postprandial blood sugar, determination of blood pressure and body weight, and a chest X‐ray should be made at regular intervals during prolonged therapy. Solu‐Medrol may be administered by intravenous or intramuscular injection or by intravenous infusion, the preferred method for initial emergency use being intravenous injection. To administer by intravenous (or intramuscular) injection, prepare solution as directed. Heparin is a heterogeneous group of straight‐chain anionic mucopolysaccharides called glycosaminoglycans having anticoagulant properties, that is preventing blood clotting. Full‐dose heparin therapy usually is administered by continuous intravenous infusion. The risk of recurrence of thromboembolism is greater in patients who do not achieve this level of anticoagulation within the first 24 hours. Subcutaneous administration of heparin can be used for the long‐term management of patients in whom warfarin is contraindicated (e. Low‐dose heparin therapy sometimes is used prophylactically to prevent deep venous thrombosis and thromboembolism in susceptible patients, e. A suggested regimen for such treatment is 5000 U of heparin given subcutaneously every 8 to 12 hours. Dosage and Administration: Dosage is 2 units / ml saline We usually use the 1,000 units/ml concentration. Protamine Description: Protamines are simple proteins of low molecular weight, rich in arginine and strongly basic. This strongly basic nature accounts for their antiheparin effect which makes it a useful antidote to heparin overdose. Antidiarrheal Compounds Lomotil Description: Lomotil (Searle & Co) is an antidiarrheal compound. Replacement Fluids Lactated Ringer’s Solution Description: Polyionic, isotonic solution for fluid therapy. For the monkey the water loss in terms of body weight is (1) Respiratory/cutaneous losses 15ml/kg, (2) Fecal 10 ml/kg, and (3) Urinary 20 ml/kg per day, with total loss of approx. A water‐ deprived animal should be given replacement fluids along with maintenance fluids. Usage: In all surgeries for maintaining the monkey’s fluid requirements during the operative period. During surgery water is also lost from the surgical site, from the vascular effects of anesthetic agents, and from sequestration of interstitial fluids from surgical trauma. Drops per minute (dpm) are computed based on: dpm = (Drp/ml)*(ml/kg/hr)*Weight/60 Dosage and Administration: 3‐15 ml/kg/hr.

They describe particular issues, which have been discussed and resolved by consensus of the Working Group. Their study of drug consumption in six European countries during the period 1966-1967 showed great differences in drug utilization between population groups. It was agreed at this symposium that an internationally accepted classification system for drug consumption studies was needed.
In areas with unstable malaria order 10 mg atarax with amex anxiety girl meme, an increasing test positivity rate among fever patients is one of the warning signs of a possible epidemic order 10mg atarax otc anxiety symptoms chest pains. Numerator: Number of laboratory-confirmed malaria cases (tested positive) Denominator: Number of suspected malaria cases tested (microscopy buy atarax 10mg line anxiety buzzfeed. Inpatient malaria deaths per 1 order atarax 25mg online anxiety episodes,000 persons Rationale Mortality is a major component of the burden caused by malaria, and the overall goal of the Roll Back Malaria Partnership is to reduce malaria deaths to near zero by 2015. With intervention coverage data and repeated estimation, understanding of the epidemiology of malaria can be improved and progress of control efforts can be tracked more effectively if estimates of parasitemia prevalence are available. Under 5 Malaria Case Fatality Rate Definition of the indicator: Under 5 malaria case fatality rate is defined as the proportion of children under five years of age who die of malaria out of the total number of children under-five (5) years admitted with malaria. In other words it expresses the proportion of children under five years with malaria who die from it (ratio of deaths to cases). Data Sources: The data is obtained from the hospital In-patient Morbidity and Mortality Returns. Use: This indicator is used to assess the performance of the malarial control programme and quality of inpatient care of the health services. Malaria-specific deaths per 1,000 persons Rationale Mortality is a major component of the burden caused by malaria, and the overall goal of the Roll Back Malaria Partnership is a 50 percent reduction in malaria-associated mortality among children under-five (5) years old by 2010. Pharmacovigilance Data sources: Complete or sample vital registration systems, verbal autopsy (surveys). Reporting Timelines Reporting of serious adverse events (death, life threatening, prolonged hospitalisation) should be reported immediately and not later than 7 calendar days. For non-serious adverse effects, reports could be submitted within a period of 28 days. It is then spread on a glass slide ("blood smear"), dipped in a reagent that stains the malaria parasites (Giemsa stain), and examined under a microscope at a 1000-fold magni- fication. Malaria parasites are recognisable by their physical features and by the appearance of the red blood cells that they have infected. These characteristics often allow the laboratory technicians to identify the type (species) of parasite causing the infection, a finding that will guide the treatment. The laboratory technicians or Biomedical Scientist can also assess the percentage of red blood cells that are infected, a measure of severity of the infection. Microscopy can only be performed by specially trained laboratory technicians and other specially trained health care workers. For microscopy guidelines and Standard Operating Procedures, refer to the Guidelines for Laboratory Diagnosis of Malaria (Ghana Health Service: 2014). There is currently no international consensus on any particular brand and type, although the field is advan- cing rapidly. For a full set of technical guidelines, refer to the Guidelines for Laboratory Diagnosis of Malaria (Ghana Health Service: 2014). Principle and Purpose The test utilises a device coated with monoclonal antibodies against malaria parasite antigens. Blood flows along the device and if malaria parasite antigens are present in the sample, the antigen antibody complex binds with a conjugate forming a coloured line (usually red). The purpose of the test is to determine if a person has been recently exposed to malaria infection. Some tests are able to distinguish Plasmodium falciparum from other malaria species. Reagents and Materials Tests contain the following components in the kit: Ÿ Instruction sheet. Method: a· Ensure the kits have not expired by checking the date at the back of the package and read manufacturer’s insert. Therefore, test results must be read only within the time specified by the manufacturer. C T Negative Results: One line ‘C’ appears in the result window Positive Results: P. Test is positive even if the test line is faint Invalid Results: No ‘C’ line appears in the results window. This means that, in patients with suspected malaria, a confirmed diagnosis is recommended, wherever possible, before giving anti-malaria treatment. On the basis of clinical judgement, these patients may be treated for malaria in addition to any other cause of fever. Treatment failure may be due to drug resistance, poor adherence to treatment, poor quality of drugs, unusual pharmacokinetic properties in that individual, or misdiagnosis. The development of malarial symptoms and signs 28 days or more after the initiation of malaria therapy is considered as indicative of a new infection, and requires appropriate investigation. In all patients with suspected severe/complicated malaria with or without fever or history of fever, the use of a confirmatory blood slide is recommended, so that parasitaemia can be quantified. Note that, high parasitaemia is not always present in severe disease and initial blood slide examination may be negative. When effective malaria prevention strategies are in place, the number of children with fever due to malaria may markedly reduce. This information will be used to determine the need for change in national diagnostic guidelines. In patients with non-severe symptoms and signs, anti-malaria treatment may be withheld if the diagnostic test is negative, and the patient carefully observed. In patients with severe symptoms and signs, anti-malaria treatment should be offered if the malaria test results are negative, and repeat blood film examination is recommended to confirm the diagnosis. Although clinicians may treat patients for malaria even if the test results are negative, they must note that, in all cases, fever may have another cause. Apart from preventive measures, early diagnosis and complete treatment are the important modalities that have been adopted to contain the disease. In view of widespread chloroquine resistance in Plasmodium falciparum infection, and other recent developments, the national policy has been revised to meet these challenges. These guidelines are the collaborative effort of National Vector Borne Disease Control Programme, National Institute of Malaria Research and experts from different parts of the country. The aim of this endeavour is to guide the medical professionals on the current methods of diagnosis and treatment based on the national drug policy (2008). This manual deals with the treatment of uncomplicated malaria and specific antimalarials for severe disease. The general management should be carried out according to the clinical condition of the patient and judgement of the treating physician. The warning signs of severe malaria have been listed so as to recognize the condition and give the initial treatment correctly before referring them to a higher facility. It is hoped that these guidelines will be useful for doctors involved in the management of malaria. Prompt and effective treatment is also important for controlling the transmission of malaria. The continued treatment of such cases with chloroquine is probably one of the factors responsible for increased proportion of P.
