If overdose should occur, seek medical attention immediately. Erythromycin also affects the metabolism of calcium channel blockers that use the cyp 3a4 pathway ie, felodipine, nifoldipine, and nifedipine. Nifedipine is extensively metabolized to highly water-soluble, inactive metabolites accounting for 60 to 80% of the dose excreted in the urine.

What are they? The eleven calcium-channel blockers currently licensed can be divided in to two major classes. The dihydropyridines amlodipine, felodipine, isradipine, lacidipine, lercanidipine, nicardipine, nifedipine, nimodipine and nisoldipine ; , act predominantly as peripheral vasodilators. The nondihydropyridines verapamil and diltiazem ; also slow the heart rate and atrio-ventricular node conduction and are negatively inotropic. All calcium-channel blockers except nimodipine are licensed to treat hypertension. Some are also indicated for the treatment of angina, Raynaulds phenomenon or subarachnoid haemorrhage. What is the calcium-channel blocker controversy? Concern has previously been raised that calcium-channel blockers may increase the risk of cardiovascular events, 1 cancer, 2 and suicide.3 These concerns were based on small observational studies, or small randomised clinical trials not 4 specifically designed to assess morbidity and mortality. Three prospective and randomised clinical trials, STOP-2, 6 7 NORDIL, and INSIGHT have now been published comparing the effects of calcium-channel blockers with other antihypertensives on cardiovascular morbidity and mortality in hypertension. Although none of the studies found any differences in the frequencies of the pre-specified primary outcomes combinations of major cardiovascular events ; , some differences in cause-specific outcomes were detected. Further evidence is available from two meta-analyses. The Blood Pressure Lowering Treatment BPLT ; Trialists' and selegiline. Paul M. Rudolf and Ilisa B.G.

Stress causes high i'm not sure that the pills are obviously doing him any good and quinapril. In yet another letter, his wit only partially concealed his true concerns: "My [white] blood count this morning was 3500 [slightly out of normal range]. When I came it was 6000. At 1500 you die. They call me `2000 to go Kennedy.'" Thereafter, he reported to Billings that "they have not found out anything as yet except that I have leukemia + agranulocytosis. Took a peak [sic] at my chart yesterday and could see that they were mentally measuring me for a coffin." But then, catching himself, he concluded once again with a flurry of sexual bravado.40 His letters disclose a person frustrated with, if not ashamed of, his illnesses, which he always sought to conceal. Indeed, a Kennedy could do no less. His exaggerated adolescent obsession with sex, too, seems to reflect compensation for his self-perceived weaknesses. Invariably, he continued to feel overshadowed by brother Joe even in matters of health. He wrote home from Peter Bent Brigham Hospital that "Joe's blood count [white cell] was 9400[; ] mine for comparison was 4000 which makes him twice as healthy."41 Kennedy's mysterious blood illness of 1934-1935 has never been adequately diagnosed. No doubt, however, he had a weakened immune system marked by a low white blood cell count ; that caused recurrent infections in which stress and fatigue undoubtedly played roles. The illness might have been hepatitis, as some have later surmised.42 The gastrointestinal problems, characterized by cramping abdominal pain alternating with diarrhea and constipation that accompanied the primary infection, was most likely a preexisting condition made worse by possible hepatitis. Because the Mayo Clinic, Dr. Murphy, and others could not find anything organically wrong with his digestive tract, Kennedy most likely suffered from irritable bowel syndrome IBS ; , a diagnosis of exclusion. Once thought to be caused solely by stress or emotional problems, gastroenterologists today have discovered a relationship of the enteric nervous system-- the nerves of the brain to the gut--in which stress can be an important consideration, and diet an important aspect of its treatment. Irritable bowel syndrome tends to run in families Kennedy's father, mother, and sister Eunice suffered from intestinal problems ; , and it tends to afflict those pressured to achieve.43 After his two-month stay at the Boston hospital, Kennedy returned to the family home in Palm Beach, Florida. Although his health had slightly improved, his frenetic social life concerned his father, who had advised him to stay out of school for the year and to undergo treatment in Boston. "The only consideration I have . your happiness. I really think you are a pretty good guy, " Joe Sr. concluded.44 He persuaded him to seek full recovery in the warm, dry air of Arizona, where social distractions supposedly would be reduced to a minimum. Against the advice of Dr. Murphy, who was concerned about the absence of medical care there, Joe Kennedy sent John Kennedy to the Jay Six Cattle Ranch in Benson, Arizona, on the recommendation of, for example, short acting nifedipine.

Drugs: Nicotine was obtained from DBH chemicals Ltd. Poole, England ; . Ifedipine and verapamil were purchased from a local pharmaceutical outfit in the city of Ibadan, Nigeria. Hot plate test: The original method of Eddy and Leimbach [16] as modified by Ibironke et al. [17] was employed. The hot plate temperature was maintained at 52 2.0C and a cut off time of 60 sec was imposed to avoid significant tissue damage. Pain sensitivity was evaluated by the response latency for paw licking on the hot plate. For the purpose of the experiment, the animals were divided into 3 groups of 8 rats each and treated as follows. Normal saline i.p, 10 mL kgG1 ; + Nicotine i.v, 1 mg lkgG1 ; 15min later. Group II: Nifedopine i.p, 0.05-0.20 mg kgG1 ; + Nicotine i.v, 1 mg kgG1 ; 15 min later. Group III: Verapamil i.p, 0.05-0.20 mg kgG1 ; + Nicotine i.v, 1 mg kgG1 ; 15 min later. Group I: About 30 min after the administration of nicotine, the animals were placed on the hot plate and latencies were measured at 15 min intervals for the next one hour. Statistical analysis: Values were expressed, as means S.E.M. Statistical significance was determined using the students' t-test. Values with p 0.05 were considered significant and aceon. Generics like veramamil and nifedipine are pretty cheap. OKT3 monoclonal antibody therapy and visual loss Sir, In their report on visual loss complicating acute renal allograft rejection in a 30-year-old female Dr Jin et al. Nephrol Dial Transplant 1995; 10: 2144-2146 ; suggest this severe side effect to be related to OKT3 monoclonal antibody therapy. Although some reports on ophthalmological problems following OKT3 administration have been published recently, we believe that the presented data do not allow this conclusion [1, 2]. The authors fail to exclude acute cytomegalovirus CMV ; infection which is well known to cause chorioretinitis with perivascular infiltrates, exudates, and haemorrhage, and a permanent reduction in visual acuity [3, 4]. The classical lesions are due to vasculitis and often involve both macula and papilla. We base our argument on personal experience with a renal transplant recipient who developed severe neuritis of both optic nerves, necrotizing retinitis and permanent visual loss during an episode of otherwise subclinical CMV infection. This happened 10 days post-operatively when the patient was on high-dose steroids and cyclosporin, but had not received OKT3. Reply by authors Sir, CMV infection usually develops 4-6 months after transplantation, probably reactivation due to prolonged immunosupression. The patient preoperatively was IgG anti-CMV antibody positive as usual transplant recipients in our centre. We have not seen chorioretinitis in over 1000 patients including over 200 treated with pulse solumedrol therapy. Recently we studied CMV reactivation, and the results were presented at the 4th Congress of Asian Society of Transplantation Dr Wie et al., August 1995 ; . Using an immunohistochemical assay for CMV antigenaemia in peripheral blood, we found positive results in about 60% of transplant recipients, but no chorioretinitis was detected in high titre patients who also recieved solumedrol pulse therapy or OKT3 therapy. We did not study CMV in the reported retinitis case because there were no other symptoms of CMV infection, e.g. fever, leukopaenia, CMV viral pneumonia, at the time and perindopril.

Rom heightening obesity rates to increased ADD attention deficient disorder ; today's children are facing a medical crisis. But the good news is with appropriate intervention the health of this generations children may be restored. In the last two decades the number of children considered obese has doubled. Obesity increases the risk for coronary-artery disease, high blood pressure and even diabetes. In the past these conditions were primarily adult diseases, but are now showing up in children as young as three and four. Heart disease, high blood pressure and even diabetes can start developing in young children even if symptoms do not prevail well into adulthood this is why it is important to begin a child's life with a healthy lifestyle, including a healthy diet and plenty of physical activity. It is recommended that children 6-12 years of.

HBP pills are known as "Triple C's" or "Skittles." Poison control centers reported the number of abuse and misuse cases involving dextromethorphan increased from 93 in 1998 to 188 in 1999 to 263 in 2000 to 366 in 2001 and to 429 in 2002. The number of cases involving abuse or misuse of Coricidin HBP increased from two in 1998 to four in 1999 to 145 in 2000 to 236 in 2001 to 266 in 2002. DPS labs examined two substances in 1998 which were dextromethorphan, 13 in 1999, 36 in 2000, 17 in 2001, and 39 in 2002. Outreach workers in the Houston area report an emerging trend in the use of Coricidin HBP Cough and Cold pills "Triple Cs" ; by, for example, short acting nifedipine. Initial post-PCI laboratory blood tests should include coagulation studies, cardiac enzymes, and serum electrolytes. Elevation of the cardiac enzymes can indicate that a silent myocardial infarction has occurred i.e., infarction unannounced by chest pain ; . If an abnormal cardiac enzyme laboratory value appears, the nurse notifies the physician immediately because the patient's postoperative care might need to be modified to prevent further injury. The nurse plays a significant role in observing and assessing angina that recurs soon after a PCI procedure. Any chest pain demands immediate and careful attention because it may indicate either the start of vasospasm or impending occlusion. The patient may describe angina as a burning, squeezing heaviness or as sharp mid-sternal pain. Other signs and symptoms of myocardial ischemia include ischemic ECG changes elevation of the ST segments or T-wave inversion ; , dysrhythmias, hypotension, and nausea. The nurse notifies the physician immediately of any such change in the patient's condition because it is impossible to tell merely by observation whether the change indicates a transient vasospastic episode, which can be resolved with vasodilation therapy, or an acute occlusion requiring emergency surgery. If vasodilation therapy is indicated, it may be administered as described subsequently unless the patient is severely hypotensive; in that case, vasodilation is contraindicated. At the first sign of vasospasm, the nurse gives oxygen by mask or nasal cannula. For fast, temporary and possibly permanent ; relief, 0.4 mg of nitroglycerin, 5 mg of isosorbide, or 10 mg of nifediipne is administered sublingually. In addition, the IV drip of nitroglycerin should be titrated to maintain a blood pressure adequate to ensure coronary artery perfusion and to alleviate chest pain. In conjunction with the onset of the chest pain, a 12-lead ECG reading is recorded to document any acute changes. If the angina resolves and any acute ECG changes caused by medical therapy disappear, it is safe to assume that a transient vasospastic episode occurred; however, if the angina continues and the ECG changes persist, redilation or emergency bypass surgery should be considered. If the post-PCI course is uncomplicated, the sheaths are removed after 3 to 4 hours, and a pressure dressing is applied to the site. A variety of mechanical clamps or hemostasis devices may be used to facilitate hemostasis after sheath removal. The patient must continue complete bed rest for 4 to 6 hours after the sheaths are removed. A normal, low-sodium, or low-cholesterol diet may be resumed, depending on the preference of the physician and the needs of the patient. During the recovery period, the nurse can introduce the patient to the rehabilitation process, emphasizing ways to combat the advance of CAD. Efforts should be made during this instruction to reinforce the importance of aerobic conditioning with regular, moderate exercise and reasonably paced increases. Also, the nurse explains that such abuses as frequent stress, excessive weight, and smoking promote CAD and that the patient has the power and responsibility to avoid these abuses by behavior modification. See Box 18-5 for instructions for the patient post-PCI. Box 18-7 describes implications for the older patient. After PCI, the patient is asked to take medications that help prevent thrombus formation and maintain maximal and reminyl.
Felodipine were comparable to the controls. Higher doses of felodipine 0.5 and 1.0 mg kg ; caused significant reductions in both the magnitude of the increase in flow rate and its duration. Mean arterial blood pressures during the period of each anoxic challenge were calculated both pre- and post-drug administration table 3 ; . MABPs tended to be slightly greater during challenges given after administration of the lower doses of nifedipne and felodipine 0.01 and 0.05 mg kg ; . This may have accounted for the slightly larger non-significant ; % increases in CBF recorded post-drug in these experiments. Following the larger doses of niffdipine and felodipine 0.5 and 1.0 mg kg ; , the post-drug MABPs during anoxic challenges were similar to those recorded predrug slightly higher after nifedipine; slightly lower after felodipine ; . Changes in arterial blood pressure cannot therefore be held responsible for the large decreases in the CBF responses to anoxic challenges following dihydropyridine administration. Discussion The present results show that nifedipine and felodipine failed to significantly enhance basal cerebral blood flow as measured by a venous outflow technique. With the higher doses of both agents there was an initial small fall in systemic blood pressure, and this may have negated any increase in cerebral blood flow due to decreased central vascular resistance. Our failure to observe an increase in CBF is in keeping with the results of Edvinsson et al. , n who were unable to demonstrate any effect of nifedipine 1.0 mg kg ; on cerebral blood flow in the rat. Other investigators have failed to observe an increase in CBF following the administration of another dihydropyridine calcium an. Currents are present in the skeletal muscle of juvenile dogfish. We attempted to examine lamprey Lampetrafluviatilis, L. ; muscle, but calcium currents were found to run down rapidly and it was impossible to test the effect of nifedipine although charge movement in these animals has been found to be nifedipine sensitive; Inoue et al. 1994 ; . Thus dogfish represent the `lowest' vertebrates in which nifedipine-sensitivecurrents have been demonstrated, which, together with the currenvoltage characteristics of the channel, indicates that they are L-type currents. The results also imply that vertebrate voltage-sensitive E-C coupling mechanisms may be extended to this `lower' vertebrate. The effect of calciseptine Unlike nifedipine, calciseptine was found to have a selective effect on the L-type calcium currents we examined in that it differentially blocks vertebrate skeletal muscle and invertebrate and protochordate types of calcium currents. As calciseptine suppresses both cardiac and neuronal L-type currents but is ineffective on skeletal muscle L-type channels in vertebrates De Weille et al. 1991 ; , our results extend the selective resistance of skeletal muscle L-type currents to calciseptine down the vertebrate sub-phylum to dogtisli. The invertebrate muscle L-type currents we examined were sensitive to calciseptine; current block was achieved at concentrations of 0.2 , UM which is comparable to the results of De Weille et al. 1991 ; on vertebrate tissue. The dogfish L-type calcium current was insensitive to calciseptine concentrations of up to There are at least two explanations for the . insensitivity of vertebrate skeletal muscle L-type calcium currents to calciseptine. It may be that the position of these channels within the t-tubule system which is lacking in protochordates and squid ; limits access of the toxin. However, this is unlikely as vertebrate cardiac muscle, which also has a t-tubule system, has calciseptine-sensitivechannels. It has also been shown that L-type currents in chaetognath muscle, which possesses both a t-tubule system and sarcoplasmic reticulum, are blocked by calciseptine Tsutsui et ul. 2000 ; . An alternative explanation which is one we favour ; is that these channel sub-types have different molecular structures. lrnplications for physiology The sensitivity L-type calciuni currents in invertebrates and protochordates to calciseptine indicates that vertebrate cardiac muscle and neuronal L-type calcium currents are analogous to the more `primitive' invertebrate sub-types of L-type calcium currents. Recently it has been argued, largely on the basis of molecular structure, that invertebrates are unlikely to possess different L-type calcium current sub-types Jesiorski et al. 2000 ; and our results confirm this view.

DISCUSSION It is well established that cholinergic agonists are of major importance for the stimulation of antral smooth muscle contraction and that their effect is mediated by muscarinic receptors. In various smooth muscle cells, the action of cholinergic agonists involved the occupation of specific receptors, activation of receptor-coupled G-proteins and subsequent activation of the second messenger systems, which would lead to the mobilization of Ca2 + from intracellular storage pools[10]. Certain steps of the signaling pathway s ; for the cholinergic contraction of antral circular smooth muscle in rats are still not understood, for example, the second messenger system or the functional characteristics of the muscarinic receptor subtypes involved. In our study the cholinergic rat antral circular muscle contraction in vitro was sensitive to the depletion from the extracellular Ca2 + that significantly diminished the cholinergic contraction. This finding along with the inhibitory effect of nifedipine indicated a dependence on extracellular Ca2 + influx via L-type calcium channels[50]. It is still not clear whether cholinergic contractile pathways of antral circular smooth muscle are mediated by PTX-sensitive GTP-binding protein through an increased inflow of extracellular calcium, or mediated via PTX-insensitive, inositol triphosphate IP3 ; -dependent pathway. The circular muscle of cat esophagus and the lower esophageal sphincter LES ; were reported to be linked to different pathways. LES circular muscle cholinergic contraction was shown to be linked to the PTX-insensitive pathway, whereas esophageal circular muscle cholinergic contraction has been reported to be linked to the PTX-sensitive pathway[11-14]. In the present study, pretreatment with PTX significantly inhibited the contractile response to bethanechol of the antral smooth muscle strips in the organ bath and of the dissociated myocytes. More than one muscarinic receptor may be responsible for cholinergically mediated contractility at a particular area[6, 22, 51-56]. A major role for M3 and a minor role for M2 receptors in cholinergicinduced smooth muscle contraction have been shown at the tissue of various species and organs[57-59], but it is still not clear how different receptors may interact to mediate a specific function. For example, M2 receptor might serve as an inhibitory presynaptic autoreceptor[60], or M2 receptor could act by gating cation channels that were subsequently modulated by M3 receptors[61].

Circulation 2004; 109: 613619. The criteria for patentability are clear. Patents are available for any invention, whether product or process, in any field of technology, provided it is new, involves an inventive step and is capable of industrial application. If an invention meets these criteria, it is entitled to patent protection. If it does not, it is not patentable. Of these criteria, the most relevant here is inventive step. The invention must not have been obvious to a person skilled in the relevant art at the time the application for a patent was first filed, taking into account the state of the art at that time. There is no common understanding around the world on how this criterion should be applied and TRIPS provides no guidance. The precise manner in which it is applied differs from country to country. It even differs over time within the same country. Significant progress has, however, been made in harmonizing the standard, particularly in the US, Japan and Europe. This harmonized standard should, in ICC's view, in time become the "gold standard" for patents globally. In the meantime, it may be necessary and appropriate, to encourage investment in local research and manufacturing, for developing countries to adopt a lower threshold to provide easy access to patents for local entrepreneurs. But in ICC's view, it cannot be right to require such countries to adopt a higher standard of inventive step. In any event, neither the inventive step requirement, nor the other basic criteria, make any distinction between different types of innovation for example between "incremental" and "discrete", or between "me too" and "breakthrough" innovations. As with any innovation, all of these have to be judged against the same basic rules, and that, in ICC's view, is entirely appropriate.
