The therapeutic profile of zolmitriptan in clinical practice

INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 8 2004
H.C. Diener
Summary The efficacy and tolerability of the 5-HT1B/1D -receptor agonist zolmitriptan was evaluated in an open post-marketing surveillance study in 12,919 patients, treating 36,510 migraine attacks. Mean visual analogue scale scores for pain decreased (6.9,2.2; 68% improvement) and scores for impairment of normal activities decreased (6.6,2.2; 67% improvement) at 2 h after dose. Non-headache symptoms of migraine resolved in 73,86% of attacks. Improvement was achieved within 2 h in >80% of attacks and within 1 h in 37% of attacks. This high level of efficacy was achieved with a single 2.5 mg dose in 95% of attacks. Compared with previous migraine treatments, 85% of patients preferred zolmitriptan for efficacy and 56% for better tolerability. Corresponding preference rates were 87 and 63% when compared with ergot alkaloids. Adverse events occurred in 2% of patients and were either typical class effects or known symptoms and complications of migraine. These results provide evidence for the high efficacy and good tolerability of the 2.5 mg dose of zolmitriptan in clinical practice in migraine. Zolmitriptan was very well tolerated, with patients expressing a distinct preference for zolmitriptan over previous treatments. [source]


Latest news and product developments

PRESCRIBER, Issue 4 2008

Suicide warning for all antidepressants All antidepressants are to include a warning of the risk of suicide in their product information, the MHRA says. The requirement formerly applied only to SSRIs but, following a US review of safety data, the Agency says the risk is similar for all classes of antidepressants. Patients at increased risk include young people with psychiatric morbidity and those with a history of suicidal ideation. Patients are at increased risk of suicide until remission occurs, and clinical experience shows that the risk is increased during the early stages of recovery. Confusion over type 2 diabetes management Contradictory findings have been reported from two studies of intensive management of type 2 diabetes. The STENO-2 study (N Engl J Med 2008;358:580-91) found that tight control of blood glucose, blood pressure and lipids plus low-dose aspirin in 160 patients with type 2 diabetes and microalbuminuria significantly reduced all-cause mortality, cardiovascular events, cardiovascular death and microvascular complications by 40-60 per cent. The US National Heart, Blood and Lung Institute has announced the end of the intensive treatment arm of the ACCORD study (unpublished). This study was comparing intensive lowering of blood glucose below currently recommended levels (target HbA1C <6 per cent) with conventional management in adults with type 2 diabetes at especially high risk for heart attack and stroke. Although mortality was reduced in both arms compared with other populations, intensive treatment was associated with increased mortality equivalent to three deaths per 1000 patients per year over four years. Another antibiotics campaign The Government has launched another campaign to promote public awareness that antibiotics are not appropriate for viral infections causing coughs, colds and sore throats. Get Well Soon , Without Antibiotics is supported by a national advertising campaign and leaflets and posters encouraging the public to ask advice rather than demand a prescription. Details are available at www.dh.gov.uk. Episenta: once-daily sodium valproate Following a launch to specialists last year, a new once-daily modified-release formulation of sodium valproate is being promoted more widely to GPs. Episenta is licensed for the treatment of all forms of epilepsy and is formulated as modified-release capsules of 150mg and 300mg and sachets of modified-release granules of 500mg and 1000mg. The dose may be administered once or twice daily. Patients may be switched from enteric-coated tablets of valproate to the same dose given as Episenta. Episenta costs £5.70 or £10.90 for 100 × 150mg or 300mg capsules, and £18 or £35.50 for 100 × 500mg or 1000mg sachets. Latest NICE agenda The Department of Health has referred a new batch of topics for appraisal by NICE. Six of seven technology appraisals are for cancer drugs; the last is for dabigatran etexilate for venous thromboembolism. There will be four new clinical guidelines: autism spectrum disorders, hypertension in pregnancy, bed-wetting in children and severe mental illness with substance abuse. Two combined public health and clinical guidelines will address alcohol misuse. Varenicline vs NRT Varenicline (Champix) offers slightly greater smoking cessation rates than nicotine replacement therapy (NRT) in the long term and better symptom improvement, an international study has shown (Thorax 2008; published online:10.1136/ thx.2007.090647). A total of 746 smokers were randomised to treatment with varenicline 1mg twice daily for 12 weeks or transdermal NRT (21mg reducing to 7mg per day) for 10 weeks. Continuous abstinence rates for the last four weeks of treatment were 56 vs 43 per cent. The corresponding rates for one year were 26 and 20 per cent. Varenicline was associated with greater reductions in cravings, withdrawal symptoms and smoking satisfaction, but more nausea (37 vs 10 per cent). Adverse reactions class effect of statins The MHRA has identified several adverse effects that it says are class effects of the statins (Drug Safety Update 2008;1:Issue 7). Following a review of clinical trials and spontaneous reports, it is now apparent that any statin may be associated with sleep disturbance, depression, memory loss and sexual dysfunction; interstitial lung disease has been reported rarely. Product information is being updated to include the new information. Depression, including suicidal ideation, has also been associated with varenicline (Champix), the MHRA says; affected patients should stop treatment immediately. The combination of transdermal nicotine replacement therapy (NRT) and varenicline appears to be associated with a higher incidence of nausea, headache, vomiting, dizziness, dyspepsia and fatigue than NRT alone. The MHRA has also announced that, following the suspension of marketing authorisation for carisoprodol (Carisoma), it is considering a phased withdrawal of the closely-related meprobamate , the main active metabolite of carisoprodol. Following a successful pilot study, the public are being encouraged to report adverse reactions on yellow cards; the MHRA notes that health professionals provide more complete reports but patients include more information about quality of life. The scheme will be promoted via community pharmacies throughout the UK from February 2008. Cochrane: evidence on back pain interventions The latest release of Cochrane reviews includes three meta-analyses assessing interventions for back pain. Overall, NSAIDs were found to be effective as short-term treatment for acute or chronic back pain but the effect size was small. They were comparable with paracetamol but associated with more adverse effects; COX-2 selective NSAIDs were similarly effective, with slightly fewer adverse effects. There was no evidence that antidepressants reduced back pain but intensive individual patient education (lasting 2.5 hours) was effective for acute and subacute back pain and comparable with manipulation and physiotherapy; its effects on chronic pain were unclear.

Class, Community and Communicative Planning: Urban Redevelopment at King's Cross, London

ANTIPODE, Issue 2 2009
Ståle Holgersen
Abstract:, This paper presents an argument for considering issues of class in analyses of communicative planning projects. In these projects, class interests tend to be obscured by the contemporary preoccupation with the class-ambiguous category of "community". Through a case study of a project of urban redevelopment at King's Cross in London, we conceptualize and map class interests in an urban redevelopment project. Three aspects of the planning process that contain clear class effects are looked at: the amount of office space, the flexibility of plans, and the appropriation of the urban environment as exchange or use value. These aspects structure the urban redevelopment but are external to the communicative planning process. The opposition to the redevelopment has in the planning discourse been articulated as "community"-based rather than in class-sensitive terms. We finally present three strategies for reinserting issues of class into planning theory and practice. [source]


The Challenge of Defining Bleeding Among Patients with Acute Coronary Syndromes

CLINICAL CARDIOLOGY, Issue S2 2007
Thomas W. Wallace M.D.
Abstract Advances in the management of patients with acute coronary syndromes (ACS), specifically, the use of combined pharmacotherapy with antithrombotic and antiplatelet therapies and routine percutaneous coronary intervention (PCI), have greatly reduced rates of thrombotic outcomes and mortality in these patients. However, these same therapies also can increase the risk of bleeding and transfusion use, which are predictive of poor outcomes in patients with ACS. Accurate assessment of the risk-to-benefit ratio for any therapy depends on the use of clinically relevant, preferably standardized, definitions of endpoint events. Unfortunately, clinical trials of antithrombotic therapies have used various definitions for bleeding, most of which were originally developed for trials of fibrinolytic therapy in acute myocardial infarction (MI). These variations in bleeding definitions have complicated cross-study comparisons and assessments of drug class effects. Further, it is unclear whether these definitions remain clinically relevant in the era of routine PCI and aggressive antithrombotic therapy for ACS. Although an argument can be made for development of a standardized bleeding definition, a more prudent approach may be to develop standardized data elements, which can then be used to tailor bleeding definitions according to the goals of future clinical investigations.
