From a total of 1288 digoxin plasma levels for adult in- and outpatients determined during one year January to December 2000 ; , 942 73.1% ; were ordered for inpatients. Of these, 210 22.3% ; digoxin level determinations were randomly selected for further analysis. Charts of those patients for which a digoxin level determination was ordered and that was included in the analysis were reviewed to obtain the following information: age, sex, weight, patient status, digoxin dose and dosing interval, indication for digoxin level determination, previous digoxin level measurement during the same hospitalisation, use of concomitant drugs potentially interacting with digoxin i.e. amiodarone, quinidine, propafenone, verapamil ; , and serum creatinine concentration. To estimate the creatinine clearance as a marker for renal function we used the equation by Dettli [26]: 150 age ; body weight [kg] 0.9 [women] or 1.1 [men] serum creatinine [mmol L] ; . These data were used to categorise digoxin level monitoring as "appropriate" or "inappropriate" according to the criteria defined above. Statistical analysis Data are presented as median with the corresponding range. Ninety-five percent confidence intervals 95% CI ; were calculated for point estimates.
This chapter describes taste disorders anatomically starting from the periphery to its central connections. In olfactory and hearing disorder there is a conductive component, but this is not so with taste unless one considers saliva to be the conducting medium. Inevitably there is overlap with some conditions affecting taste both centrally and peripherally. Other causes will be described, including iatrogenic disease and trauma. Pure loss of taste is quite uncommon and apart from the lower referral rate for this condition the presence of three major afferent routes for taste from the periphery provides a back-up system in case of a single nerve failure. Even in lesions of the chorda tympani taste is sometimes preserved, possibly!

The purpose of this study was to develop a selective binding assay for 5-containing GABAA receptors. A high percentage of GABAA receptors in the hippocampus contain the 5 subunit, and this correlates with the pharmacological effects seen with 5 selective benzodiazepines BDZs ; . BDZs that interact with the 5 subtype appear to be involved in bdz tolerance, certain types of epilepsy, and bipolar affective disorder. The 5 subtype may also play a role in ethanol response. Drugs that are selective for the 5 subtype may be useful in treating these and other conditions. The use of the 5 selective radioligand, [3H]-RY80, and hippocampal membranes created a highly selective ligand binding assay that is exceptionally clean and is useful for identifying 5 reactive compounds, for instance, medicine verapamil. 5.

Abstract In many cases there is a clear established link between drug block of the hERG channel, QT prolongation and Torsade de Pointes TdP ; see review of Fermini, B. and Fossa, A. 2003 ; but there is also evidence that block potentiation of other cardiac ion channels can either lead to an increased or decreased proarrhythmic risk Antzelevitch, C. 2005 ; . For example quinidine produces TdP at low therapeutic drug concentrations, where it principally blocks hERG, but never induces TdP at higher drug concentrations where it also blocks Nav1.5 and KCNQ1 minK Antzelevitch, C. et al 1999 ; . Amiodarone also has an extremely low incidence of TdP in humans even though it blocks hERG and prolongs QTc. Again this is thought to be due to a mixed blocking action since it not only blocks the KCNQ1 minK and Nav1.5 channels but also the L-type calcium channel thereby preventing calcium-dependent early after-depolarizations and triggered activity that can lead to TdP Camm et al 2004 ; . It appears that this mixed blocking activity involving hERG and the cardiac L-type calcium channel is the reason why verapamil does not cause TdP even though it is a potent hERG channel blocker and why selective serotonin re-uptake inhibitors such as citalopram have low fatal toxicity index scores Witchel, H. J. et al 2002 ; . Due to the increasing awareness of the interaction of other ion channel types with drugs either leading to increased or decreased cardiac risk, there has become a need to test compounds across a range of cardiac ion channels early in the drug discovery process. This is now technically feasible due to the increasing availability of human cardiac ion channel cell lines Cytomyx ; and the advent of high throughput planar patch systems such as IonWorks HTTM and IonWorks QuattroTM Molecular Devices Corporation ; . Data presented here shows how Cytomyx have developed screening assays using a range of human cardiac ion channel types expressed in mammalian cell lines. Background Prolongation of the QT interval and block of hERG does not necessarily lead to TdP if compounds block multiple ion channels. Figure 1 shows the relationship between drug concentration and the increase in the QT interval and transmural dispersion of repolarization TDR, from Antzelevitch 2005 ; . For pure hERG channel blockers such as sotalol, dofetilide and erythromycin QT prolongation and TDR are closely correlated. However, more complex drugs with multiple blocking actions, such as cisapride and quinidine, show a greater propensity to cause TdP at lower drug concentrations than at higher concentrations. Other drugs rarely or never cause TdP e.g. amiodarone, ranolazine etc ; can still markedly prolong the QT interval. The reported reason for this is that even though these drugs can prolong the QT interval they minimize TDR through mixed ion channel block. Hence, a critical increase in TDR is the stimulus for TdP and not QT interval per se. Clearly knowledge of the mixed cardiac ion channel blocking actions of a given drug is useful to obtain a first approximation of cardiac risk long before it enters the clinic. Cytomyx' Cardiac Panel Cytomyx has created a portfolio of recombinant cell lines expressing cardiac ion channels for which screening assays have been developed on IonWork HT. Figure 2 shows Cytomyx' cardiac cell lines available for testing on IonWorks which represent the major ionic conductance's involved in the cardiac action potential. IonWorksTM HT and vicoprofen.

Also, a beta-blocker would be a good choice for most high blood pressure patients with a history of heart attack, because there are also trials showing a reduction in the risk of death when a beta-blocker is used. The Harvard researchers examined the prescribing practices of physicians for older high blood pressure patients enrolled in the New Jersey Medicaid program from January 1, 1991 through December 31, 1995. This involved 23, 748 new users of a high blood pressure drug. Their average age was 76 years and 11, 103 had at least one of the following conditions: diabetes, congestive heart failure, history of heart attack, or history of angina chest pain.

But this type of cancer is especially problematic in children, as their developing nervous systems are particularly sensitive to the effects of radiation, a major form of treatment for brain and other solid pediatric tumors. Despite careful measures to minimize damage to healthy tissue close to the brain tumor, conventional radiation therapy, which uses X-rays to destroy cancer cells, may result in impaired growth, cognitive deficits, and other undesirable long-term side effects. Massachusetts General Hospital is one of only three hospitals in the U.S. that offers a better alternative--proton beam therapy --for children with brain tumors such as medulloblastomas and ependymomas, as well as optic gliomas and skull-base tumors. Through the Department of Radiation Oncology's Northeast Proton Therapy Center, young patients undergo treatment that delivers high-dose radiation precisely to their tumor while minimizing damage to healthy tissue. Protons, which are generated by a cyclotron, deposit their radiation dose differently than X-rays, which are generated by a linear accelerator. In general terms, X-rays deliver energy to the entire area, while proton beams primarily target only the tumor. This property is especially valuable when treating tumors close to sensitive tissues or critical organs, such as the brain. Proton treatment for brain tumors requires highly individualized planning to ensure that the radiation conforms precisely to the tumor throughout the entire course of treatment, which is typically administered five days a week for 4 to 7 weeks. Requiring the expertise of a multidisciplinary team under the direction of the patient's radiation oncologist, this planning involves using computed tomography CT ; and sometimes magnetic resonance imaging MRI ; to create three-dimensional images of the tumor and surrounding structures so that radiation can be appropriately dosed and targeted. It also requires creating individualized devices to position and immobilize the patient so that each day's treatment can be accurately and consistently reproduced. Young children unable to remain still for treatment planning and daily treatments may also require general anesthesia.

Reproductive: gynecomastia, loss of libido, erectile dysfunction. Eye: progression of cataracts lens opacities ; , ophthalmoplegia. Laboratory Abnormalities: elevated transaminases, alkaline phosphatase, -glutamyl transpeptidase, and bilirubin; thyroid function abnormalities. Adolescent Patients ages 10-17 years ; In a 48-week controlled study in adolescent boys with heFH n 132 ; and a 24-week controlled study in girls who were at least 1 year post-menarche with heFH n 54 ; , the safety and tolerability profile of the groups treated with MEVACOR 10 to 40 mg daily ; was generally similar to that of the groups treated with placebo see CLINICAL PHARMACOLOGY, Clinical Studies in Adolescent Patients and PRECAUTIONS, Pediatric Use ; . OVERDOSAGE After oral administration of MEVACOR to mice, the median lethal dose observed was 15 g m2. Five healthy human volunteers have received up to 200 mg of lovastatin as a single dose without clinically significant adverse experiences. A few cases of accidental overdosage have been reported; no patients had any specific symptoms, and all patients recovered without sequelae. The maximum dose taken was 5-6 g. Until further experience is obtained, no specific treatment of overdosage with MEVACOR can be recommended. The dialyzability of lovastatin and its metabolites in man is not known at present. DOSAGE AND ADMINISTRATION The patient should be placed on a standard cholesterol-lowering diet before receiving MEVACOR and should continue on this diet during treatment with MEVACOR see NCEP Treatment Guidelines for details on dietary therapy ; . MEVACOR should be given with meals. Adult Patients The usual recommended starting dose is 20 mg once a day given with the evening meal. The recommended dosing range of lovastatin is 10-80 mg day in single or two divided doses; the maximum recommended dose is 80 mg day. Doses should be individualized according to the recommended goal of therapy see NCEP Guidelines and CLINICAL PHARMACOLOGY ; . Patients requiring reductions in LDLC of 20% or more to achieve their goal see INDICATIONS AND USAGE ; should be started on 20 mg day of MEVACOR. A starting dose of 10 mg of lovastatin may be considered for patients requiring smaller reductions. Adjustments should be made at intervals of 4 weeks or more. The 10 mg dosage is provided for information purposes only. Although lovastatin tablets 10 mg are available in the marketplace, MEVACOR is no longer marketed in the 10 mg strength. Cholesterol levels should be monitored periodically and consideration should be given to reducing the dosage of MEVACOR if cholesterol levels fall significantly below the targeted range. Dosage in Patients taking Cyclosporine or Danazol In patients taking cyclosporine or danazol concomitantly with lovastatin see WARNINGS, Myopathy Rhabdomyolysis ; , therapy should begin with 10 mg of lovastatin and should not exceed 20 mg day. Dosage in Patients taking Amiodarone or Verapzmil In patients taking amiodarone or verapanil concomitantly with MEVACOR, the dose should not exceed 40 mg day see WARNINGS, Myopathy Rhabdomyolysis and PRECAUTIONS, Drug Interactions, Other drug interactions ; . Adolescent Patients 10-17 years of age ; with Heterozygous Familial Hypercholesterolemia The recommended dosing range of lovastatin is 10-40 mg day; the maximum recommended dose is 40 mg day. Doses should be individualized according to the recommended goal of therapy see NCEP Pediatric Panel Guidelines, CLINICAL PHARMACOLOGY, and INDICATIONS AND USAGE ; . Patients and xenical.
Similar situation, including the United States, Germany, Austria, New Zealand, Greece and Portugal, have implemented the provision in order to comply with the minimum TRIPS patent term. Canada also faced the same situation as Taiwan and the other aforementioned countries, but did not make the requisite change in its law. The United States brought a WTO settlement case against Canada. In that case, the WTO panel confirmed the nature of the obligation and found that Canada had not met its TRIPS obligation by not granting additional protection to those "less than twenty year patents" that were in existence on the date that the TRIPS Agreement applied in Canada. The case against Canada is especially instructive of the commercial impact of a country's failure to implement this obligation in the frame required by the TRIPS Agreement. To this date, Canada has failed to meet a TRIPS obligation that it had been obliged to meet on January 1, 1996. In the intervening period, many of the old seventeenyear patents, which should have received an additional term of protection, fell into the public domain, costing U.S. patent holders millions of dollars in lost sales. Taiwan's failure to provide the additional term of protection required by the TRIPS Agreement will have an adverse impact on the wide range of intellectual propertydependant U.S. industries operating in Taiwan. PhRMA urges the U.S. Government to make this issue a priority in the WTO accession negotiations with Taiwan and in the overall trading relationship with Taiwan. Other Issues Two other issues are worth noting. Zero Tariffs: Taiwan committed to achieve zero tariffs for pharmaceuticals by 2002. Companies currently face on average, a 12.5% import duty on finished products. This level of tariff barrier is hard to justify in a country as internationally competitive as Taiwan. Faster implementation of the zero tariff accord would be a welcome sign of cooperation by Taiwan. Moreover, Taiwan should abolish tariffs on all categories of pharmaceuticals recognized by other nations that have implemented this exercise. There is particular opportunity for this upon Taiwan's' accession to WTO. Relief Fund for Victims of Side Effects: The Department of Health in 1998 created a relief fund to compensate patients and their families harmed through use of approved medicines. The Fund will initially cover damage caused by Western drugs as opposed to Traditional Chinese Medicines ; . Most manufacturers have joined the Fund through a voluntary contribution of 0.1% sales revenue of pharmaceuticals, and companies are represented on the management committee of the Fund. Industry's major concern remains that Traditional Chinese Medicines and health foods likewise be included in the Fund, in order to eliminate any discriminatory treatment, for instance, 240mg verapamil. ARE T-TYPE CALCIUM CHANNELS CAUSALLY INVOLVED IN SMOOTH MUSCLE CELL PROLIFERATION? McLatchie LM, * Harper JV, * Brooks G and Shattock MJ. Centre for Cardiovascular Biology and Medicine, King's College, St Thomas' Hospital, London, and * School of Animal and Microbial Sciences, University of Reading, PO Box 228, Reading, UK. Aberrant smooth muscle cell growth is a major component of in-stent stenosis and vascular remodelling. Ttype calcium channel expression has been linked with cell proliferation but it remains unclear whether it is a causal factor. We have addressed this question in rat A10 VSMC's by modulating T-type calcium channel expression through pharmacological blockade and stable over-expression. Mibefradil, nickel, TH1177 and vegapamil blocked proliferation in these cells with IC 50 values of 8.6 0.5 M, 428 14 M, 17.5 0.5M and 70 3 M respectively. Eliminating differences due to the presence of serum, calcium concentration etc. Mibefradil, nickel, TH1177 and verapamil block T-type current measured using whole-cell voltage clamp with IC50 values of 0.4 0.1 M, 1500 300 mM, 1.2 0.3 M and 17 2 M respectively. These values for mibefradil, TH1177 and verapamil are all slightly lower than the anti- proliferative values but there is a correlation between the amount of T-type current block and block of proliferation. Nickel was anti-proliferative at concentrations well below those required to block the T-type current suggesting an alternative site of action. Over-expression of the T-type calcium channel 1H led to the production of a stable clone with T-type calcium current 20 fold higher than vector controls. This clone also demonstrated an increased proliferative capcaity of 2.6 fold at 72 hours as compared to our first vector control. However, comparing a number of stable clones revealed no correlation between T-type current magnitude and rate of proliferation. Although not ruling out a role for T-type calcium channels in proliferation these results suggest that T-type calcium current magnitude is not a primary causal factor in the rate of A10 smooth muscle cell proliferation. The drugs used in this study do clearly modulate proliferation and it remains to be seen where they act and whether these represent possible therapeutic target s ; for the treatment of instent stenosis or vascular remodelling and zestoretic.

What is Hepatitis C? Hepatitis C is a liver disease caused by the hepatitis C virus HCV ; , which is found in the blood of persons who have this disease. HCV is spread by contact with the blood of an infected person. Who should get tested for Hepatitis C? Persons who ever injected illegal drugs, including those who injected once, or a few times many years ago. Persons who were treated for clotting problems with a blood product made before 1987 when more advanced methods for manufacturing the products were developed. Persons who were notified that they received blood from a donor who later tested positive for hepatitis C. Persons who received a blood transfusion or solid organ transplant before July 1992 when better testing of blood donors became available. Long-term hemodialysis patients. Persons who have signs or symptoms of liver disease e.g., abnormal liver enzyme tests ; . Healthcare workers after exposures e.g., needle sticks or splashes to the eye ; to HCV-positive blood on the job. Children born to HCV-positive women.

Twice in the last few months, a public talk of Donald Rumsfeld has been interrupted by people in the audience calling him a war criminal and accusing him of lying to get the United States into war. This happened in a meeting room at the very respectable National Press Club in Washington and again at a forum at the equally respectable Southern Center for International Policy in Atlanta. In Chile, last November, as former dictator Augusto Pinochet moved closer to being tried for the deaths of thousands, he declared to a judge: "I lament those losses and suffer for them. God does things, and he will forgive me if I committed some excesses, which I don't believe I did."[4] Dubya couldn't have said it better. Let's hope that one day we can compel him to stand before a judge, but not one appointed by him. ly built up Europe economically, including our wartime enemies, and allowed them to compete with us." Even those today who are very cynical about US foreign policy, who are quick to question the White House's motives in Afghanistan, Iraq and elsewhere, have no problem in swallowing this picture of an altruistic America of the period of 1948-1952. After World War II, the United States, triumphant abroad and undamaged at home, saw a door wide open for world supremacy. Only the thing called "communism" stood in the way, politically, militarily, and ideologically. The entire US foreign policy establishment was mobilized to confront this "enemy", and the Marshall Plan was an integral part of this campaign. How could it be otherwise? Anticommunism had been the principal pillar of US foreign policy from the Russian Revolution up to World War II, pausing for the war until the closing months of the Pacific campaign, when Washington put challenging communism ahead of fighting the Japanese. This return to anti-communism included the dropping of the atom bomb on Japan as a warning to the Soviets.[5] After the war, anti-communism continued as the leitmotif of foreign policy as naturally as if World War II and the alliance with the Soviet Union had not happened. Along with the CIA, the Rockefeller and Ford Foundations, the Council on Foreign Relations, various corporations, and other private institutions, the Mar and zithromax.

Direct relationship between the calcium channel blocking activity of these compounds and their ability to reverse drug resistance, but a correlation between the presence of a cationic nitrogen atom in the molecules and MDR reversing activity seems to be important. 7 Some dihydropyridine derivatives are more effective than verapamil in enhancing the antitumoral activities of anthracyclines and Vinca alkaloids in vitro. Also, in terms of possible side effects in vivo, some specific molecular types of dihydropyridine derivatives with low calcium channel blocker activity could have less toxic effects than verapamil at plasmatic concentrations able to reverse MDR.8 In this paper we report data on the MDR reversing activity of the R-enantiomer GR66234A ; and the L-enantiomer GR66235A ; of a dihydropyridine derivative called telupidine. Teludipine is less cardiotoxic than verapamil and contains a butyl group in the aromatic ring that makes the molecule more lipophilic than other dihydropyridine derivatives Figure 1 ; . Renantiomer GR66234A has 100 times lower calcium channel blocking activity than GR66Z 35A. 7, 8 some patients are currently being put on calan verapamil, pfizer ; or other oral calcium channel blockers. During the sampling period there appeared to be no significant plasma decay in desloratadine concentrations whether desloratadine had been administered alone or with verapamil. Alternatively, while desloratadine concentrations in brain homogenates remained stable during the sampling period for desloratadine + verapamil treated mice, an apparent decline in brain desloratadine levels in the animals treated only with desloratadine was detected with an apparent disappearance and vicoprofen.
