Their treatment reviewed at their next routine appointment. Following these measures in Europe, the US FDA has issued a public advisory for rosuvastatin, advising that many of these recommendations are "already captured in the FDA approved labelling for rosuvastatin Creestor ; ", with this labelling including a specific section titled Myopathy Rhabdomyolysis. The FDA is not proposing to change the rosuvastatin Creshor ; labelling following the recent review, but wishes to "reemphasize to physicians the importance of carefully following the recommendations in the current product label". In the Canadian Adverse Drug Reactions Monitoring Programme CADRMP ; database, there are eight Canadian post-market cases of rhabdomyolysis associated with rosuvastatin. Five cases occurred with rosuvastatin 40mg daily, two cases have occurred at the 10mg usual recommended daily dose and for the remaining case the dose was not specified. The involved patients all had one or more pre-existing risk factors for statin induced myotoxicity. AstraZeneca, under advice from Health Canada has warned health-care professionals to be cautious when prescribing rosuvastatin in patients with preexisting risk factors or concomitant medications which pose an increased risk for statin induced myopathy or rhabdomyolysis.

Prescription medication crestorPediatrics 18 years of age ; : Treatment experience with CRESTOR in a pediatric population is limited to 8 patients with homozygous familial hypercholesterolemia. None of these patients was below 8 years of age see DOSAGE AND ADMINISTRATION, Use in Children ; . Geriatrics 65 years of age ; : There were no clinically significant pharmacokinetic differences between young and elderly patients 65 years ; see DOSAGE AND ADMINISTRATION, Use in Elderly ; . However, elderly patients may be more susceptible to myopathy see WARNINGS AND PRECAUTIONS, Muscle Effects, Pre-disposing Factors for Myopathy Rhabdomyolysis ; . Race: Results of pharmacokinetic studies, including a large study conducted in North America, have demonstrated an approximate 2-fold elevation in median exposure in Asian subjects having either Filipino, Chinese, Japanese, Korean, Vietnamese or Asian-Indian origin ; when compared with a Caucasian control group. This increase should be considered when making rosuvastatin dosing decisions for Asian patients and the dose of 40 mg is contraindicated in these patients see ACTION AND CLINICAL PHARMACOLOGY, Pharmacokinetics, CONTRAINDICATIONS and DOSAGE AND ADMINISTRATION, Race and diovan. Cardiovascular: Antihyperlipidemics: Statins and Statin Combinations Public Comment Claude Lardinois, M.D., F.A.C.P., F.A.C.N., professor of medicine, UNR School of Medicine, disclosed that he is on the Speakers' Bureau for several pharmaceutical companies and participates in ongoing education programs with drug companies. He has no grant or research support from those companies. He presented a handout to the committee noting the 2006 ranking of drugs in the United States ranked Lipitor as number one, Zocor twenty-five, Frestor fifty and Pravachol one-hundred seventy-six. He stated that the group of lipid lowering agents that seem to have the most evidence is Lipitor atrovastatin ; , Zocor simvastatin ; and niacin. Safety is of concern and there has been a lot of discussion regarding Crestor rosuvastatin ; and proteinuria issues. He referred to his handout indicating that the 170 FDA report demonstrates that as the dose of atrovastatin, pravastatin, simvastatin, is increased, proteinuria goes down. Two companies have demonstrated reductions in albuminuria. Albuminuria is a powerful marker for cardiovascular disease. In the next ten years, it will turn out to be a greater risk factor for heart disease than hypertension. There is good outcome data for simvastatin, pravastatin and atorvastatin; there is none for Crestor, Lescol, Vytorin or Zetia. He recommended the committee include drugs on the PDL that have good safety records and good outcome efforts. He states that cost is important to him but not until there is data to show that what is given is safe and efficacious. Dr. Horne asked regarding Lipitor on the PDL and Dr. Lardinois replied that his recommendation is to move Lipitor to preferred because of the clear, emerging outcome data in the last 2-3 years. Dr. Bryg asked regarding Crestor and Vytorin. Dr. Lardinois recommended leaving Crestor on the PDL, but until albuminuria data is shown that it decreases as with the other three statins, he has serious reservations about using the agent. There is no data on Vytorin. The inhibiting of the cholesterol in the gut is fascinating and it does help to lower LDL. The important thing is seeing outcome results to feel comfortable in using these agents. Dr. Phillips asked about pravastatin which is non-preferred. Dr. Lardinois said there is good mortality data with pravastatin and simvastatin. Mandy Hosford, Astra Zeneca, spoke in support of Crestor. In response to Dr. Lardinois' concerns, she stated that there is published data on improvement of urinary albumin excretion upon high dose Crestor versus Lipitor therapy showing that neither is superior in attenuating albumin excretion at higher doses. Her company also has ongoing clinical trials in Type II Diabetes patients presenting with proteinuria. David Abrahamson, Merck Schering Plough, spoke in support of Vytorin. Dr. Heard asked if Mr. Abrahamson has literature which specifically addresses proteinuria. Mr. Abrahamson stated that are two sources of protein, tubular and glomerula. In head-to-head trials Vytorin versus Crestor, significant differences were noted and tubular in nature. What is known to date is that with most of the other statins, as the dose is increased, the protein levels diminish but there has not been a study in a renal population prospectively. The impact is unknown until there are outcome studies. What is known is that with most statins at higher doses, there is a decrease in protein levels. The mechanisms are unknown and the outcomes based on that finding are unknown. Dr. Lardinois commented that albuminuria and proteinuria need to be separated. Most of the literature as referenced in the report is dipstick proteinuria not albuminuria. There are studies with Lipitor and Zocor as you increase the dose, albuminuria is decreased. There are LDL receptors on the mesangium of the glomerulas. When the LDL burden is reduced, the flow through the nephron is improved and albuminuria is decreased and that is seen in an increasing dose. Most patients don't need 80mg of Lipitor. There is reduction in lower doses. The best predictor of cardiovascular disease is not the LDL cholesterol, but the total cholesterol HDL ratio. Effect As with other HMG-CoA reductase inhibitors, coadministration of CRESTOR and coumarin e.g. warfarin ; may result in a rise in International Normalized Ratio INR ; compared to coumarin alone. In healthy subjects, the coadministration of rosuvastatin 40 mg 10 days ; and warfarin 25 mg single dose ; produced a higher mean maxINR and AUC-INR than achieved with warfarin alone. Coadministration of CRESTOR 10 and 80 mg to patients on stable warfarin therapy resulted in clinically significant rises in INR 4, baseline 2-3 ; . The mechanism for this effect is unknown, but is likely due to a pharmacodynamic interaction with warfarin rather than a pharmacokinetic interaction as no relevant differences in the pharmacokinetics of either drug was observed. Simultaneous dosing of CRESTOR with an antacid suspension containing aluminium and magnesium hydroxide resulted in a decrease of rosuvastatin plasma concentration by approximately 50 and hytrin.

High doses of Nexium in five trials totaling 12, 000 patients. All this to show the drug helped the esophagus heal in an extra one in 20 patients, compared with Prilosec or competitor Prevacid. The payoff: Nexium now is touted as "the healing purple pill, " hawked in ubiquitous TV spots. In one, a sterling-haired man in black cites the "exciting news" from one of the studies and concludes, "Better is better." Nexium is the third-best-selling drug in the world, according to IMS Health, with .7 billion in sales and an ad budget of 6 million last year. Never mind that some of the trials were stacked: In three of the big trials AstraZeneca pitted high doses of Nexium versus half the dose of Prilosec; it never bothered to test whether twice the Prilosec dose would be equally effective. AstraZeneca says there are "clear differences" between the two purple pills and notes that one equal-dose study showed a statistical advantage for Nexium in esophageal healing. In another instance AstraZeneca staged trials that fizzled but used them for a new ad claim anyway. Before it won approval in August 2003, AstraZeneca studied its Lipitor look-alike, Crestor, for cholesterol reduction, in 24, 000 patients, hoping to prove superiority. But the only dose of Crestor that clearly beat Lipitor turned out to cause kidney problems and never won fda approval. Nonetheless, after Crestor's debut AstraZeneca used ads featuring a voiceover by the stentorian actor Patrick Stewart of Star Trek: The Next Generation, in Seussian rhyme: "When Crestor performed in a head-to-head test, its lowering effect was clearly the best." That claim brought a rebuke from the FDA in March 2005. The company halted the ads, but it now is testing Crestor in 30, 000 more patients. AstraZeneca notes that Crestor is the only statin shown to clear plaque out of the arteries. The drug industry has begun to restrain its own advertising. Last June Bristol-Myers Squibb took a first step, announcing that it would wait a year after drugs hit the market to begin running ads, leaving time for doctors to learn about a medicine and for side effects to crop up. Companies are now submitting ads to the FDA before they run and are more clearly stating big risks. But myriad drugmakers have plenty of ways to game the system. In the market for new schizophrenia treatments Lilly and Johnson & Johnson and others have run 21 head-to-head trials--and 90% of the time the conclusions favor the sponsor's drug, according to research in the American Journal of Psychiatry. Nine studies compared Lilly's Zyprexa to Johnson & Johnson's Risperdal. All five Lilly-paid trials favored Zyprexa; three of four J&J studies favored Risperdal. Lilly stands by its high scientific standards and says the results highlight the need for more independent studies. Another analysis, in Archives of Internal Medicine, tallied 56 studies of painkillers; not once was the sponsor's drug deemed inferior. "The comparative studies are a joke. They are comical. A lot of the scientific literature these days is worthless, " says psychiatrist Jack E. Rosenblatt. "The whole process has been corrupted, " says British bone researcher Aubrey Blumsohn. "It is getting worse as the financial stakes are rising." Blumsohn contends procter & gamble for years refused to supply raw data for a 2003 study he led comparing its drug Actonel to Merck's competing drug, Fosamax, even after he became suspicious that Procter's analysis was skewed in favor of Actonel. "It was a process of intimidation, " says Blumsohn, who was suspended from his job at the University of Sheffield after he complained to the British press. He recently left after agreeing to an undisclosed. That more information becomes available to us allows us to make a reasonable recommendation based on the data, so that we can say the frequency of those adverse events and the descriptions used for those adverse events is more appropriately labelled. Additionally, I think, when it comes to patient information leaflets, it is a very good example of how patient information leaflets can be worded more appropriately. Seroxat is an example where we have extensively done user testing. Patient information leaflets, while they legally have to be compatible with a summary of product characteristics, sometimes are written in a way which is unhelpful to patients. We have found through the Seroxat process and through extensive user testing that the patient information leaflet is now more friendly. I think we would also recommend that more user testing happen with patients, such that they are written from a blank sheet of paper whilst still being compliant with the summary of product characteristics. Q714 Dr Naysmith: Despite what all of you have said, does this episode not indicate looking a bit more closely at some of the harmful eVects of drugs--and I know you disagreed with the original question, Dr Patterson--that it might be worth spending a bit more resources looking at that rather than looking at the beneficial eVects once you get to the market? Dr Dollow: Someone who has a patient in front of them recognises that any prescribing decision is taken on the basis of the risks of the disease the patient is suVering from, the risks of prescribing the medicine and the benefits that medicine is going to bring. When we think about the evaluation of our medicines and safety, we have to take it in those contexts. We cannot separate them. People have recommended, for example, that safety evaluation be separated within the MHRA. I would, I think for clarity, recommend to the Committee that it is actually all within the MHRA but is in separate lines at the moment. We would support keeping it within the MHRA but ensuring that the safety and the eYcacy are considered together. Dr Patterson: In terms of the things that are recognised as potential issues, either from the trials or from the literature, we do diligently follow those. I would give you an example. On Crestor which was mentioned earlier, on a weekly basis now I see a graph of the incidents and a report every week as to key events that may have happened, number of deaths, etc, and where that sits opposite the whole literature. That is worldwide on a weekly basis. Where it is an issue is where something is totally new; i.e it has not been described before. There it comes down to pattern recognition, which might come from a doctor seeing it in several of their patients and often comes from aggregating together experience over a number of trials for the development of longstanding trials in the course of the market place. That will always happen, particularly with the much less frequent side eVects. If something happens one in a thousand, and you have 3, 000 patients in your database or even 30, 000. Introduction An application of DSM-IV criteria Zurich cohort ; produced prevalence for mania and hypomania of 5.5% by age 35. In a recent study, Angst 1 998 ; reported that, while 13 epidemiologic studies since 1980 had persistently found a low lifetime prevalence of mania 0.0-1.7% ; , the application of DSM-IV criteria by trained clinical psychologists produced a prevalence for mania and hypomania of 5.5% by age 35. A broadening of diagnostic criteria to include other aspects of the bipolar spectrum hypomania, cyclothymia, and bipolar disorder not otherwise specified ; in six studies since 1978 yields a prevaience ranging between 3.0 and 8.8%. Depression usually causes more subjective distress than does mania. Hence, patients are more likely to seek help for depression than for mania. This high prevalence suggests that bipolar disorder is a general health problem with significant social and economic sequel, a fact of which policy makers should be aware. Clinical Phenomenology of Bipolar Subtypes. Akiskal and Pinto 1999 ; broadened the bipolar spectrum and suggested several subtypes as follows: Bipolar 1: Full - Blown Mania Bipolar 1 2 Depression with protracted hypomania Bipolar 2: Depression with hypomania Bipolar 2 1 2 Cyclothymic depression Bipolar 3: Antidepressant associated hypomania. Bipolar 3 1 2: Bipolarity Masked and unmasked by stimulant abuse. Bipolar 4: Hyperthymic Depression. Bipolar V & VI: Not yet defined. Mixed states Mixed states, also called dysphoric mania, constitute 5 - 7 % of cases. This category has been recently acknowledged as a distinct entity of bipolar disorder, occupying an intermediate position on a spectrum between mania and depression. lt is a severer form of bipolar disorder and its phenomenology consists of a superimposed independent mania and depression Morbidity and Social Cost Bipolar disorder is the 6th leading cause of disability worldwide and is a recurrent illness in more than 90% of patients. Suicidal ideation is present in 25-50 % in cases of mixed mania. At least 25% of bipolar patients attempt suicide, while the actual suicide rate is estimated between 11-19 %. Co morbid substance abuse or other psychiatric diagnoses McElroy et al., 2001 ; and or medical conditions Strakowski et al., 1994 ; are highly prevalent in bipolar disorder. Functional recovery often lags behind symptomatic and syndromal recovery. Recurrent episodes may lead to progressive deterioration in functioning and the number of episodes may affect subsequent treatment response and prognosis, hence the importance of early identification and intervention. Psychosocial disability from bipolar disorder remains extensive and encompasses multiple domains, including work and social functioning, independent community living, family adjustment and lopid. 5 days later i could not sleep, my mind was racing, and i was having a panic attack and could not keep a clear thought.
