Such fngerprint profles are usually distinctive and would form a benchmark for the drug cheap 60mg raloxifene fast delivery, especially when the identity of the active principles is not known or when chemical markers are not available raloxifene 60 mg overnight delivery. In this process, it is important to take into account all of the information available in the fngerprint analysis in toto to ascertain the quality of the sample. This phytochemical profle can form an important component of quality-control criteria for herbal drugs. The fnger- print profles are also useful for characterization of extracts showing specifc activity. Active principles: one or a few of the compounds specifc to the drug that are proved to be responsible for the claimed activity of the respective herbal drug [e. Chemical markers: compounds reported from the respective drugs, although not specifc to the drug, and activity specifc to the drug has also not been proven (e. For those plants for which active principles are known, their presence in the sample can be ascertained by cochromatography and comparison of the Rf and absorption spectra with that of the standards of the marker compounds. Wherever active principles are not known, fngerprint profles can include the general marker compounds. In addition, to have a complete picture of phytochemical profle, in the former case the fngerprint profles should also include the other marker compounds [31, 46]. Tracks 1 and 2, sample; track 3, E-guggulsterone standard; track 4 Z-guggulsterone standard Table 19. For example, E- and Z-guggulsterones in the oleogum resin of Com- miphora wightii. However, in most of the cases it is diffcult to fnd such specifc marker compounds. For example, vasicine, the active principle of Adhatoda vasica leaf, is the major alkaloid of the drug, and by virtue of it, it is an im- portant biomarker of Adhatoda vasica leaf. However, it cannot be considered as “marker compound” of Adhatoda vasica since it is present in other plants as well (e. Secondary metabolites are usually found to be pres- ent in many members of the same family and sometimes across several families [47], so much so that in chemotaxonomy some of the secondary metabolites are used to settle disputes regarding the classifcation of certain taxa. Considering the above, is it possible to fnd a specifc marker for each of the herbal drugs? Can we call the other compounds widely present, like gallic acid, quercetin, and rutin mark- ers, albeit general markers? The question remains whether such chemical con- stituents can be called “marker compounds” at all. If a compound is identifed that is specifc to a drug, but is not an active principle and is a minor constituent, can it still be called a marker by virtue of being specifc to the drug? It may best be left to the discretion of the scientist working with specifc herbal samples to decide which important chemical constituents to use in chemoprofling, with- out passing the judgment as to the chemical compound selected is a marker or not. In this scenario, the existing categorization of marker compounds as active principles, chemical markers, and general markers as described in the previous section may be taken into consideration. In the absence of known active principles any other compound/s that are predominantly present in the herb can be used as chemical markers. The multiple markers of a drug are usually a mixture of active principles and chemical markers. The different ingre- dients of a formulation contain important marker compounds, which can be active principles and/or chemical markers. Suitable extraction procedures are adapted to effect complete extraction of the compounds from the samples. The presence of the markers in a sample extract is ascertained by cochromatogra- phy of the sample extracts and standards of marker compounds and compari- son of the R /retention time and absorption spectra with that of the standardsf of the marker compounds. This is imperative because to resolve the maximum number of compounds for fngerprinting purposes, suitable mobile phases needed to be evolved. The mo- bile phase requirement for resolving specifc markers, however, can be differ- ent. The methods so developed help in identifying the presence of these impor- tant markers and indicate the presence of the respective raw materials in the formulation. Although multi- ple-marker-based evaluation ensures the quality with respect to the ingredients containing these marker compounds, it is practically impossible to have marker compounds specifc to each of the ingredients of the formulation. Furthermore, quan- tifcation of important marker compounds of the formulation forms an addi- tional parameter in maintaining the quality of the product [26–31, 64–67]. In fact, complete fngerprint profles should be established for all of the drugs and formulations, even in cases where active principles are known, keep- ing in view the possible synergistic activity of several chemical components of the herbal drugs. The profle so evolved by taking in to account all of the in- formation in toto, is distinctive for the drug and would form its benchmark, especially when the active principles are not known or when chemical markers are not available for analysis. A comprehensive specifcation for the drug would thus include fngerprint profles along with chemical marker/active principle analysis that would estab- lish identity and purity and, to an extent, ensure effcacy. The estimation of individual compounds from a particular raw material has two applications: 360 M. Track 1: authentic sample; Tracks 2 and 3: market samples b see next page Chapter 19 Phytochemical Standardization 361 Fig. If the compound happens to be one of the active principles, the analysis would ensure the quality of the raw material and the possible effcacy of the formulation in which it becomes a part (e.

After adequate trial of lifestyle and risk factor modification, initiate treatment using medication known to be effective in combinations known to be effective. This report provides an evidence-based approach to the prevention and management of the most common variants of hyperlipidemia, with emphasis on primary and secondary prevention of coronary artery disease. It makes extensive use of population based evidence such as the Framingham projections to assist the clinician with identification of persons in need of more intensive treatment. These were updated to reflect the results from large randomized controlled trials completed in the early 2000s in 2004. The working group focused on Patient-oriented outcomes, primarily reduction in myocardial events. The reduction in morbidity as well as mortality from this disease is reflected in the following recommendations. Because the therapy is considered relatively innocuous, little attention was paid to other patient factors, such as well being, for these recommendations. These recommendations may not be appropriate for patients who suffer from unrelated diseases that may limit lifespan to less than 10 years or patients who find medication use onerous. In addition, patients who must make choices regarding medications because of cost should be made aware that the medications used to treat this condition are expensive and should be strongly encouraged to manage the condition with lifestyle modifications initially and perhaps offered extra time to do so. The Encounter Chief Complaint: Typically the condition is detected through screening of asymptomatic individuals either in the community or in the office setting. The complaint is typically regarding the evaluation or follow- up of hyperlipidemia although it may be that the initiation of treatment occurs with an incidental finding the patient has multiple risk factors or the level is markedly elevated. A complaint of University of South Alabama, Department of Family Medicine June 30, 2008 94 chest pain that is assessed as non-cardiac will often generate a serum lipid profile that may indicate the patient is at an elevated risk of cardiac disease. History of Present Illness (new evaluation): Patient should be encouraged to identify what concerns exist. Patient should then be queried regarding major risk factors for cardiovascular disease. Inquire about changes in status, focusing on possible development of cardiac disease. Consider review of Risk Factors approximately every 12 to 24 months, more frequently if poor control. General – Look for evidence of tobacco use, general body habitus looking for truncal obesity, acanthosis nigricans.

Early and aggressive airway management— surgical if needed—is indicated in these patients cheap raloxifene 60mg visa. Gastrointestinal symptoms including nausea buy raloxifene 60mg line, cramping, and diarrhea may be seen, and are associated with particularly severe anaphylactic reactions. Clinical Criteria for Diagnosis of Anaphylaxis Clinical criteria were developed from a multidisciplinary symposium to best identify anaphylaxis early and accurately. Anaphylaxis is highly likely if any one of the fol- lowing three diagnostic criteria exist. Acute onset (minutes to hours) with reaction of the skin and/or mucosal tissue in addition to respiratory symptoms or hypotension. Skin symptoms include itch- ing, redness, hives, generalized urticaria, and mucosal edema, Respiratory mani- festations include laryngeal stridor, bronchospasm, bronchorrhea, and hypoxia. Hypotension results from extravasation of fluid from the vasculature and loss of vasomotor tone. Two or more of the following occurring rapidly (minutes to hours) after exposure to a likely allergen: involvement of the skin-mucosal tissue, respiratory symp- toms, hypotension, or gastrointestinal symptoms. Hypotension occurring rapidly (minutes to hours) after exposure to known allergen for that patient. Treatment The primary initial therapy for anaphylaxis is epinephrine (Table 10–2). Epineph- rine will act as a pressor for hemodynamic support, a bronchodilator to relieve wheezing, as well as to counteract released mediators and prevent their further release. Subcutaneous administration of epinephrine is no longer recommended as it has been proven less effective than intramuscular administration. Initial administration is intramuscular in the anterior thigh with the more concentrated 1:1000 dose at 0. If there is no response or if the patient is already demonstrating cardio- vascular compromise, intravenous administration should be started immediately. In general, all ampules of epinephrine have 1 mg of medica- tion (1 mL of 1:1000 = 1 mg of medication; 10 mL of 1:100,000 = 1 mg of medica- tion). One method of administration is to place 1 mg (1 ampule) of epinephrine into 1 L of intravenous fluid (equivalent to 1 lg/mL) and infuse to 1 to 4 cc/min (1-4 lg/min). Cau- tion should be exercised in the elderly and in those with known cardiovascular disease. Intravenous administration of epinephrine can cause hypertension, tachy- cardia, dysrhythmias, and myocardial ischemia. Inhaled beta agonists are indicated for wheezing, and nebulized racemic epineph- rine has been hypothesized to decrease laryngeal edema. Intravenous glucagon has been proposed for individuals on a-blockers in the event they are unresponsive to epinephrine. Glucagon may overcome hypotension by activating adenyl cyclase independent of the beta receptor. Other adjuvants include systemic steroids, specifically methylprednisolone and prednisone. Steroids will not take action for at least 6 hours, but will blunt fur- ther immune responses. It should be remembered that these other medications, while safe and easy to administer, are not first-line agents, and will not counteract respiratory and cardiovascular compromise. Which of the following most suggests anaphylaxis rather than a simple allergic reaction? Hypotension indicates a systemic reaction and cardiovascular compromise, thereby classifying this allergic reaction as anaphylaxis. The other option may all be part of an anaphylactic response, but may also just be simple allergic reactions. If there is significant respiratory or airway compromise, then the patient should be controlled. Again, early recognition of anaphylaxis and immediate dosing of epineph- rine is most important. This patient has severe anaphylaxis, and it would be appropriate to move straight to intravenous epinephrine. If intravenous dosing is not immediately available, then intramuscular epinephrine should be given. Because of the significant laryngeal edema, endotracheal intubation will be nearly impossible; hence, cricothy- roidotomy may be required. After securing the airway, steroids, beta agonists, H1 and H2 antagonists should be administered. It is much easier to extu- bate a patient without severe laryngeal edema than to intubate a patient with an occluded posterior oropharynx. Look for causes of anaphylaxis after you have started your initial resus- citation. Steroids, antihistamines, and beta agonists are all helpful pharmacologic adjuvants for managing the many symptoms of anaphylaxis.
