In evaluating numbers of spontaneous reports against patient exposure 4 purchase altace 1.25mg with mastercard, different options are possible for the appropriate units; each has advantages and disadvantages heart attack karaoke demi lovato order altace 2.5mg without prescription. However arrhythmia used in a sentence buy altace visa, there is commonality across many countries for expedited reporting of serious unexpected cases blood pressure chart readings for ages purchase altace 1.25mg fast delivery, whether of local or foreign origin heart attack jack look in my eyes 1.25mg altace amex. Although considerable progress has been made toward international harmonization of requirements and practices hypertension medication discount 5 mg altace with visa, considerable work remains to eliminate inefficiencies and unnecessary differences so as to optimize the contributions of pharmacovigilance. It was attended by health professionals, researchers, academics, media writers, representatives of the pharmaceutical industry, drug regulators, patients, lawyers, consumers and international health organizations. High scientific, ethical and professional standards and a moral code should govern this activity. The inherent uncertainty of the risks and benefits of drugs needs to be acknowledged and explained. Decisions and actions that are based on this uncertainty should be informed by scientific and clinical considerations and should take into account social realities and circumstances. Flaws in drug safety communication at all levels of society can lead to mistrust, misinformation and misguided actions resulting in harm and the creation of a climate where drug safety data may be hidden, withheld, or ignored. Fact should be distinguished from speculation and hypothesis, and actions taken should reflect the needs of those affected and the care they require. These actions call for systems and legislation, nationally and internationally, that ensure full and open exchange of information, and effective standards of evaluation. These standards will ensure that risks and benefits can be assessed, explained and acted upon openly and in a spirit that promotes general confidence and trust. The following statements set forth the basic requirements for this to happen, and were agreed upon by all participants, from 30 countries at Erice: 1. Such information should be ethically and effectively communicated in terms 219 of both content and method. Facts, hypotheses and conclusions should be distinguished, uncertainty acknowledged, and information provided in ways that meet both general and individual needs. Education in the appropriate use of drugs, including interpretation of safety information, is essential for the public at large, as well as for patients and health-care providers. Drug information directed to the public in whatever form should be balanced with respect to risks and benefits. All the evidence needed to assess and understand risks and benefits must be openly available. Constraints on communication parties, which hinder their ability to meet this goal, must be recognised and overcome. Every country needs a system with independent expertise to ensure that safety information on all available drugs is adequately collected, impartially evaluated, and made accessible to all. Exchange of data and evaluations among countries must be encouraged and supported. A strong basis for drug safety monitoring has been laid over a long period, although sometimes in response to disasters. Innovation in this field now needs to ensure that emergent problems are promptly recognised and efficiently dealt with, and that information and solutions are effectively communicated. These ideals are achievable and the participants at the conference commit themselves accordingly. Details of what might be done to give effect to this declaration have been considered at the conference and form the substance of the conference report. Throughout the various meetings, concepts were presented and debated, drafts of proposals were reviewed and discussed, and two surveys of the industry were carried out (one on practices and experience in preparing periodic safety update reports (see Chapter 4) and the other on knowledge and use of patient exposure information (see Chapter 5)). The meetings subsequent to April 1997 were as follows: July 1997 (Geneva), November 1997 (New York), April 1998 (Paris), November 1998 (Philadelphia), March 1999 (Amsterdam), July 1999 (Berlin), and August 2000 (Barcelona). In May 1999 and February 2000, the appointed editorial committee for the report (A. Lumpkin) held meetings to resolve outstanding issues and design the overall report. However, it is common practice to rely on at least two such sources for literature searches. Perhaps the two most widely used general biomedical databases for this purpose are Medline and Embase. In addition there are several more general biological and scientific databases such as SciSearch, Biosis, and the Derwent Drug File. There are also specialized databases which deal with specific disease areas (such as CancerLit and AidsLine), or with the toxicological effects of drugs (ToxLine). Medline Medline is a vast source of medical information, covering the whole field of medicine including dentistry, veterinary medicine and medical psychology. The database covers clinical medicine, anatomy, pharmacol ogy, toxicology, genetics, microbiology, pathology, environmental health, occupational medicine, psychology, and biomedical technology, etc. The database corresponds to the printed publications: Index Medicus, Index to Dental Literature, International Nursing Index and various biblio graphies. It is also available in many manifestations on the World Wide Web, several of which are free to use. It features unique international journal coverage and includes many important journals from Europe and Asia not found in other biomedical database; overall coverage is approximately 4,000 journals published in 70 countries. The emphasis of the database is on the pharmacological effects of drugs and chemicals. Additional areas of coverage are human medicine and biological sciences relevant to human medicine, health affairs (occupational and environmental health, health economics, policy and management), drug and alcohol dependence, psychiatry, forensic science, pollution control, biotechnology, medical devices and alternative medicine. It indexes all significant items (articles, review papers, meeting abstracts, letters, editorials, book reviews, correction notices, etc. Some 3,800 of these journals are further indexed by the references cited within each article, allowing for citation searching. It selectively covers the worldwide pharmaceutical literature; papers chosen may cover the chemistry, analysis, pharmaceutics, pharmacology, metabolism, biochemistry, interactions, therapeutic effects and toxicity of a drug. Papers from over 1,150 scientific and medical journals and conference proceedings are included. Each year approxi mately 9,000 articles on adverse drug reactions are published in the scientific literature. All articles are sent to recognised authorities who critically assess the information and distil the key elements for inclusion. Speculative or unsubstantiated statements on the side effects of ethical drugs are not included. The database consists of bibliographic records referencing cancer research publications dating from 1963 to the present. In addition, proceedings of meetings, government reports, symposia reports, selected monographs, and theses are also abstracted for inclusion in the database. Even with a single company statement, however, there can well be debate and sometimes discrepant views between personnel within an organization as to what a safety data mean. In addition, 22 physician monitors enployed by either Glaxo or SmithKline Beecham Pharmaceuticals completed the exercise. Despite these efforts, reporting discrepancies within and between organisations are ocurring. These are felt to be not only due to cultural differences between organizations and regulatory agencies. In the absence of standardized guidelines, such opinions caused by a nonstandar dized view can lead to the same case history being reported to some regulatory authorities but not to others, even though reporting is based on the same reference data and similar regulations. No attempt was made to compare responses from regulators attending the meeting with the others, although it would have been interesting. As can be seen, there appears to be a different philosophy between Europe and the United States in the way the events are interpreted, particularly where the outcome is death (examples 6 and 9). Individuals in the United States would tend to report a fatality as an unlabeled event, whereas in Europe this is generally viewed as an outcome rather than a factor relevant to labeledness. For example, in Europe, 97% of the respondents accept that if myocardial infarction is to be labeled, death 230 due to myocardial infarction is also labeled. Only 43% of the respondents in the United States, however, would accept fatal myocardial infarction to be labeled if only myocardial infarction appeared in the labeling. Also of interest is that in Europe, rather than the United States, cyanosis secondary to hypoventilation was equated with respiratory depression (Example 8). As can be seen, medical opinion was unanimous among 22 medical monitors in only one example (Example 1) where the greater anatomical specificity did not affect the labeledness of lung fibrosis. Table 2 was designed to gather responses on whether certain medical events should be considered to be serious. For instance, in Example 1, total blindness for 30 minutes was considered to be serious in Europe, whereas in Example 3, mild anaphylaxis was thought to be serious in the United States. This is in contrast to the overall total of 95% who consider this event to be serious. The information found in Table 3 was designed to determine whether the respondents felt, based on the available case details, the case should be reported to regulatory authorities. The results suggest a fairly uniform transatlantic view about whether or not a case should be reported. Fewer in Europe than in the United States, however, would report a case where the reporter could not remember the age or even the sex of a patient (Example 167). Discussion None of the 30 examples surveyed achieved a totally unanimous view and so the guidelines presented below are all based on a majority verdict. To some extent the non-uniform opinion is surprising because of the relatively small number of individuals who took part in the survey, with many having a substantial amount of expertise in the area of drug safety. It appears that in many situations reporting is practiced according to medical common sense. It is believed that the newly proposed United States regulations, in the wake of fialuridine experience, should serve to move general opintion further toward reporting based on medical opinion. Worthy of comment is that the extra reporting is not always within the United States. For example, blindness for 30 minutes, respiratory collapse, and respiratory depression would be more frequently viewed as medically serious and would be reported more often in Europe. The United States reporting practice is more to view fatalities as unlabeled unless death is specifically mentioned in the label. Before suggesting a pragmatic way forward to best benefit from the harmonization initiatives, the following 20 guidelines are proposed. An unlabeled diagnosis which relates to a group of symptoms or signs which are labeled, the new case is not in itself labeled. For example, if anaphylaxis is labeled, then a report of a patient who experienced hypotension, wheezing, and urticaria would be considered to be labeled (69%). If a report is serious in the medical sense, even though it is not serious in the regulatory sense. On the other hand, a threat of suicide is not considered to be serious (83%), nor in itself is an emergency room or outpatient department visit (97%). If the investigator persists in specifying a case is drug-related, even though this view is medically nonsensical, the case should be considered drug-related and reported to the regulatory authorities. Spontaneously reported cases should always be considered to be possibly drug-related, even if an alternative explanation is given by the reporter (72%). The overall majority of individuals surveyed would not report to regulatory authorities a case where the details of a specific patient could not be recalled. In the United States, however, 72% would report the unidentified patient and 59% the series of eight cases. In those instances where the brand name of a generic drug is stated to be unknown, the case should be processed and reported to regulatory authorities by the company which becomes aware of the adverse event (70%). In the United States, this obligation generally falls to the original brand name manufacturer of the drug. Even with a single company statement, however, there is often debate and sometimes discrepant views between personnel within the organization.
