Cannabis 'link to increase in schizophrenia'
STRONGER cannabis - and users getting stoned to a 'far more debilitating degree' - could lead to a rise in cases of schizophrenia and present the NHS with a much larger bill, a leading drugs expert will warn tomorrow. The Observer via NewsEdge Corporation : STRONGER cannabis - and users getting stoned to a 'far more debilitating degree' - could lead to a rise in cases of schizophrenia and present the NHS with a much larger bill, a leading drugs expert will warn tomorrow. Professor John Henry believes that the Government, in its decision to relax the laws on cannabis, has overlooked the burden that greater use puts on health services and on families - as well as the way young people are seeking to heighten the effects of the drug. Henry, a toxicologist and professor of accident and emergency medicine at Imperial College London, will talk about the medical risks associated with the drug at a conference tomorrow. He fears that several hundred more young people could end up in hospital suffering from schizophrenia, and might need anti-psychotic drugs to deal with their condition. A year ago the Government announced plans to reduce the classification of cannabis from category B to C, after a recommendation from the Police Federation that it was far less harmful than other drugs. The reclassification takes place this summer, and smoking a joint will then be much less likely result in arrest or prosecution for possession. The policy change follows a controversial scheme in Lambeth, London, in which the Metropolitan Police focused on hard drug users. The Met said it achieved great results against hard drug dealers, but some health workers were worried that children in the area felt it was now legal - and safe - to smoke cannabis. There is mounting concern among psychiatrists about the impact of the softening of the law. Three million people are thought to smoke cannabis regularly, a quarter of them adults under the age of 29. It has been shown that more people are growing cannabis for their own consumption. Some doctors have argued that cannabis can be highly beneficial for patients suffering chronic pain, or those with multiple sclerosis. However, Henry will warn at the Royal Society of Medicine's conference that there has been a recent, dangerous shift in the way people use cannabis and alcohol. Recreational use has given way to a cultural acceptance of getting stoned regularly to a 'far more debilitating degree', according to Henry. 'Modern cannabis is nearly 10 times the strength the "flower power" generation was used to, and in Amsterdam it is at least twice as strong as in the UK,' he said. 'We know that for those who take the drug there is a fourfold increase in schizophrenia and in the chances of suffering major depressive illness. Given that we know schizophrenia accounts for some 3 per cent of the total NHS bill, the costs could go up by another 1 per cent. That should be urgently considered by the Government.' Henry believes there are emerging mental health problems associated with THC, or tetrahydrocannabinol, the main active ingredient of cannabis, which in greater concentrations makes more potent forms of the drug, such as 'skunk'. A study is to begin at the Maudsley Hospital in south London. Volunteers will be offered free cannabis, so that researchers can carry out brain scans and conduct memory tests to see how mental activity is affected. Professor Robin Murray, leading the study, used to be sceptical when cannabis was blamed. 'Relatives would say "It seems to be the cannabis that makes my son or daughter or brother psychotic" and I would say, "Oh, they're just trying to look for something to blame". We've come to realise that it does have a significant effect.' Others note that rates of schizophrenia have not risen dramatically in the past 50 years to correspond with increasing use. There is also a question over whether those who are likely to develop schizophrenia are already predisposed to take cannabis. The National Institute for Clinical Excellence estimated that treatment of schizophrenia in England and Wales was responsible for around 3 per cent of the entire NHS budget - some pounds 1 billion a year. Cliff Prior, chief executive of Rethink, a charity helping those with mental illness, said: 'There is growing evidence that cannabis may trigger schizophrenia in vulnerable people.'

In a New Study Ziprasidone Demonstrated Fast Onset of Action in Significantly Reducing Symptoms of Acute Mania in Patients With Bipolar Disorder
NEW YORK, April 4 /PRNewswire-FirstCall/ -- Bipolar patients who received Pfizer Inc's atypical antipsychotic ziprasidone showed significant improvement in symptoms of acute mania compared with those who received placebo, according to data published today in the American Journal of Psychiatry. PR via NewsEdge Corporation : NEW YORK, April 4 /PRNewswire-FirstCall/ -- Bipolar patients who received Pfizer Inc's atypical antipsychotic ziprasidone showed significant improvement in symptoms of acute mania compared with those who received placebo, according to data published today in the American Journal of Psychiatry. Results from this randomized, double-blind, placebo-controlled study demonstrated that ziprasidone produced rapid, sustained improvements in manic symptoms when compared to placebo. Significant improvements were observed within two days of treatment and were maintained throughout the three-week study. The study, which involved 210 inpatients, also demonstrated that after 7 days of treatment ziprasidone-treated patients showed significant improvement across all evaluation scales compared to those who took placebo, including symptoms of acute mania, psychosis and social functioning. "Physicians are often looking for effective treatment options to help control the multiple symptoms of acute mania in patients who suffer from bipolar disorder," said Dr. Paul Keck, Professor of Psychiatry and Pharmacology and Vice Chairman for Research, Department of Psychiatry, University of Cincinnati College of Medicine. "This study suggests that ziprasidone may be a rapid and beneficial treatment option for bipolar mania." Bipolar disorder, which is also referred to as manic-depressive illness, is a serious form of mood disorder in which patients may experience extreme 'highs,' or manic episodes, and extreme 'lows,' or periods of major depression. The condition is estimated to affect one in every 100 Americans and has a major impact on the ability to function in daily life. Bipolar disorder is estimated to cost society about $45 billion per year. Patients in the midst of a period of mania, which usually lasts at least a week, may appear to be overly energetic, extremely expansive or excessively happy. They may have difficulty sleeping, functioning in social or work situations and may overindulge in pleasurable activities. The study was conducted in the United States and Brazil. Ziprasidone patients began taking 80 mg per day and were quickly titrated to 160 mg per day by the second day. Dosing was then flexible for the remainder of the study. Efficacy was measured using standardized psychiatric assessment scales. Among ziprasidone-treated patients, there was a low incidence of movement disorders, a side-effect associated with some atypical antipsychotic medications and no clinically significant weight gain, changes in vital signs or other safety parameters. The most common side effects of ziprasidone in this study included somnolence, headache, dizziness, hypertonia, nausea and akathisia. Discovered and developed by Pfizer, ziprasidone is a serotonin and dopamine antagonist. The medicine was approved by the U.S. Food and Drug Administration in February 2001 for use in the treatment of schizophrenia. It also is approved in more than 45 countries worldwide. Ziprasidone received approval for the treatment of acute mania in Brazil in November 2002. Pfizer plans to file a supplemental new drug application FDA later this year for the treatment of acute mania. Ziprasidone is currently marketed as Geodon in the United Sates and in Brazil. Oral ziprasidone is associated with a prolongation of the QTc interval of the electrocardiogram, an effect seen with certain other marketed medicines, including some antipsychotics. This effect was well characterized in the extensive oral ziprasidone trials database and is reflected in the FDA's product labeling, which suggest that physicians use their best judgment as to whether ziprasidone is the appropriate medication based on the overall status of the patient. Pfizer Inc discovers, develops, manufactures and markets leading prescription medicines, for humans and animals, and many of the world's best known consumer products.

Painkillers against alzheimer's disease
Scientists at the University of California have discovered that common painkillers may help dissolve the brain lesions - known as amyloid plaques - that are a hallmark of Alzheimer's disease. Scotland on Sunday via NewsEdge Corporation : Scientists at the University of California have discovered that common painkillers may help dissolve the brain lesions - known as amyloid plaques - that are a hallmark of Alzheimer's disease. Non-steroidal anti-inflammatory drugs, such as Ibuprofen, bind to these amyloid plaques, helping to destroy them and prevent the growth of new plaques. According to the researchers, this may explain why people who take anti-inflammatory medication over several years seem to be at lower risk for later development of Alzheimer's disease. In a separate study conducted at both Columbia University College of Physicians and Surgeons and Stanford University, doctors found that malfunctioning brain cells, called astrocytes, may be the culprits behind the accumulation of the amyloid proteins that cause plaque to form. Everyone makes this substance, but in people with Alzheimer's disease, the production process goes haywire. They either make too much or too little, or the substance itself is degraded. As a result, the proteins clump up, forming plaques, which then lead to the death of neutrons and dementia. Alzheimer's disease often begins with mild memory lapses, after which memory, language and most mental functions gradually deteriorate. Researchers at the London School of Economics say the number of people with cognitive impairment will rise by about 66 per cent. This shows a clear need to find widely available treatments that will delay the progression of dementia. Wouldn't it be great if the answer was already lurking at the back of your medicine cabinet?

First treatment in nine years approved for bipolar mania in Canada - Zyprexa(r) helps control the symptoms of mania and prevents relapse
TORONTO, March 18 /CNW/ - Today, Eli Lilly Canada Inc. announced that Zyprexa has been approved in Canada for the treatment of manic and mixed episodes associated with bipolar disorder, also known as manic depressive illness. Canada Newswire English via NewsEdge Corporation : TORONTO, March 18 /CNW/ - Today, Eli Lilly Canada Inc. announced that Zyprexa(r) (olanzapine) has been approved in Canada for the treatment of manic and mixed episodes associated with bipolar disorder, also known as manic depressive illness. Zyprexa is the first treatment in nine years approved for bipolar mania in Canada. Zyprexa provides rapid symptom control of a broad range of symptoms associated with mania and helps prevent relapse back into mania. "Zyprexa represents a significant advancement in the treatment of bipolar disorder," explains Dr. Roger McIntyre, Assistant Professor of Psychiatry at the University of Toronto. "A recent study showed that Zyprexa works better than Lithium, the current gold standard, in preventing manic episodes. In addition, ongoing studies show that Zyprexa manages both the manic and depressive phases of the illness." Bipolar disorder affects approximately one to two per cent of the adult population.(1) Bipolar disorder is a lifelong illness characterized by disruptive swings in mood--from euphoria and irritability (manic episodes), to periods of depression. A patient may experience either "pure" episodes (manic or depressive symptoms) or "mixed" episodes (a mixture of manic and depressive symptoms at the same time). In addition to the profound impact that the illness has on patients, there can be an equally severe impact on the patient's family and caregivers. Twenty-five to 50 per cent of people with bipolar disorder will attempt suicide at least once.(2) "When I'm in a manic phase my mind runs rapidly, I can't concentrate, I can become delusional and lose touch with reality. And in my depressed state nothing interests me. There seems no point in doing anything and everything seems too hard. It's overwhelming. Work is almost out of the question," explains Danny Marinus, bipolar patient. "It's awful for my family. They never know what mood I'll be in and what's going to happen next. Zyprexa has stabilized my mood and has helped me live a normal life again." "For patients, each day spent with manic or depressive symptoms can be devastating. Those afflicted with the illness suffer from severe mood swings to overwhelming feelings of sadness and low self-worth, which can include suicidal thoughts and even suicide," says Phil Upshall, President, Mood Disorders Society of Canada. "In addition to the profound impact that the illness has on patients, there can be an equally severe impact on the patient's family and caregivers. We welcome any new advancements that may help patients with bipolar disorder move forward with their lives." Clinical Trial Results In ongoing clinical trials with bipolar patients, Zyprexa has been shown to provide rapid symptom control, help patients remain in remission longer and help prevent relapse into mania: - Rapid symptom control in bipolar mania: studies show that Zyprexa demonstrated greater efficacy than placebo in the treatment of bipolar mania,(3,4) including a higher rate of response (65 per cent vs. 43 per cent respectively).(3) Zyprexa has been shown to produce a significantly greater improvement in symptoms of mania vs. divalproex(5) - Effective in depression symptoms: Zyprexa has been shown to manage depressive symptoms in patients with manic and mixed episodes. These symptoms are particularly resistant to standard anti-manic treatment. Nearly a seven-fold improvement in depressive symptoms was seen when Zyprexa was added to another mood stabilizer(6) - More effective than the current gold standard - lithium: a year-long study showed that in the maintenance treatment of bipolar disorder, patients taking Zyprexa relapsed into mania only half as often as patients taking lithium(6) Zyprexa is generally well tolerated. Adverse events reported in clinical trials included somnolence, dizziness and dry mouth, but rarely led to discontinuation of trial. As with other mood stabilizers, Zyprexa can also be associated with increased appetite leading to weight gain. The recommended beginning dose of Zyprexa to treat acute manic episodes is 10 milligrams in combination therapy or 15 milligrams by itself, taken once a day without regard to meals. Zyprexa is also indicated in Canada for the acute and maintenance treatment of schizophrenia and related psychotic disorders. Since introduced in 1996, Zyprexa has been prescribed to nearly 11 million people worldwide. Lilly, a leading innovation-driven corporation, is developing a growing portfolio of best-in-class pharmaceutical products by applying the latest research from its own worldwide laboratories and from collaborations with eminent scientific organizations. Headquartered in Indianapolis, Indiana, Lilly provides answers - through medicines and information - for some of the world's most urgent medical needs.
