Expanding use of the drugs and high expectations of their effects on their introduction are followed by rising criticism and disappointments about the beneft/risk balance buy minipress 1mg overnight delivery. The cycle sometimes ends with the disappearance of the drug from the medical market and its replacement by newer drugs (which often follow similar career paths) cheap minipress 1mg fast delivery. But a drug can also reappear and start a new career cycle buy 1mg minipress fast delivery, for instance on the appearance of a new appealing disorder. We have termed these generally typical dynamics for the careers of psychotropic drugs, Seige cycles. Given the dynamic activity at any point in time, it is not surprising that different trajectories may emerge: drug careers involve bifurcations, jumps, improvisations, impasses and dead-ends. These may result from diffculties in clinical trials, new indications, changing marketing practices, public attitudes or drug policies. These more or less predictable events at one or another stage are likely to infuence the nature and course of the cycle. Periods of controversy following reports of drug safety problems as part of a drug career are excellently suited to explore these dynamics..

The proposals vary from the reduction or extension of the period of patent protection, strengthening independence and transparency of regulatory agencies, to incentives for drug development high-need, high risk areas. But these proposals fail to address the fundamental cyclical as well as contextual dynamics underlying drug development and use. Furthermore, the parties overlook what seems to have become a rather important phenomenon in drug regulation in the post-thalidomide era: the so-called double bind trade-off phenomenon. Following the thalidomide drug disaster (1958-1962), and the subsequent introduction and enforcement of high drug testing and safety standards, drug regulatory agencies came under attack for delaying the introduction of useful medicines and weakening industrial competitiveness. At the same time they faced the political criticism for approving me-too drugs or drugs later shown to have, detrimental side effects. By describing the twisting career of triazolam (Halcion®) in the Netherlands we shall point out how this regulatory double bind between safety and innovation may interfere with the pace, direction and intensity of the Seige cycle. Moreover, the Halcion case helps to understand the importance of economic, political and cultural contexts in shaping drug life cycles by creating, reinforcing, legitimating or obstructing (inter-)national career paths. Triazolam (Halcion®) and the Dutch regulatory context Triazolam was frst synthesized and tested by the American drug company Upjohn in 1969. The new compound promised to be the lead compound of a new generation of safe and short- acting benzodiazepines (benzos). Since the introduction of Librium in 1960 the members of this chemical class led the top-selling drug list in Western countries. However, over time reports on adverse effects of these minor-tranquillizers accumulated: tolerance, dependence, drowsiness, reduced alertness and other reactions leading to traffc accidents. The historian Susan Speaker shows how the critique on the making and taking of benzos 4 T. Brynner, Dark remedy; The impact of thalidomide and its revival as a vital medicine.

Nelemans, ‘Psychofarmaca in het verkeer’, Nederlands Tijdschrift voor Geneeskunde 112 (1968): 1862-8; D. By 1976 a number of clinical trials had been performed showing that the new drug was an effective and safe sleeping pill with a very short half-life that compared favourably with older benzodiazepine analogues. Triazolam allowed users who took the pill at night to function normally and drive safely the next morning without feeling groggy. Together with the Belgians the Dutch regulatory authorities were among the frst to start the review process. Like in Germany the Dutch drug market historically was regulated by pharmacists and physicians under a system derived from medieval guild authority. Additional amendments did anything but maintain the self-regulatory control by physicians, pharmacists, industry and health insurers. This state-regulated system of self-regulation was still based on the former corporative alliance model – recruiting the members of the board from both professional and government bodies. Like their American counterparts the Dutch regulatory authorities do not actually carry out safety or effcacy testing of new drugs, but merely review and assess the results of testing conducted and submitted by industry.

It should order minipress 1 mg mastercard, however order 1 mg minipress with visa, be noted that generic minipress 1mg online, for Vioxx, the frst published data come mainly from Merck, the company that produced the drug. In the light of these observations and the crisis related the withdrawal of Vioxx from the market, certain questions arise. To what extent does the research carried out before a drug is approved address all the risks suffciently? To what degree does it do so, given that the frst part of the chronology provides little information on the harmful or side effects of the medications? In any event, there are limits to the diversity of the populations involved in clinical trials and to the duration of such trials, so these two dimensions necessarily give rise to some uncertainty. The Vioxx chronology, derived from the abstracts of scientifc studies, does not really allow us, at this stage, to predict crises like those sparked by the withdrawal of the drug. Still, the difference between the chronologies of these substances brings out the fact that plant- and animal-derived extracts are not on the same level as prescription medications. In the case of the plant and animal extracts, almost all that has to be shown is that they are effective in a particular area. In the case of prescription drugs, it is also essential to demonstrate that they are not harmful or, at least, that the contributions they are likely to make outweigh any of their toxic aspects. Information from the abstracts is indicated in the fgure in accordance with its importance in the chronology of the medication: events of moderate importance are shown at a medium distance from the timeline, and events of major importance (withdrawal or approval of the drug, lawsuit or important discovery, etc. Each circle of the fgure thus represents an event referring to a scientifc abstract or a news item. It should be noted that, as far as news items from dailies are concerned, redundant references to the same event were not considered. Furthermore, events were positioned according to their valence: that is their positive (above the timeline) or negative (below the timeline) impact on the future of the drug. Lastly, for the fgure involving news from the dailies, coloured lines were added to the timeline to indicate critical incidents; that is events marking the pathway of the medication (for instance, approval, withdrawal, lawsuits, discovery of major side effects, etc. In the case of information drawn from Medline, the coloured lines represent the dimensions under study (pharmacological properties, particular indication, etc. This distinction probably stems from the fact that, in contrast to the other three substances, Vioxx is the only one to have been marketed. This observation must however be qualifed by stating that, for the most part, negative incidents emerge only after a medication is approved. The fact that negative information is generally produced by university research centres and regulatory agencies gives rise to two concerns. First, once a medication is marketed, it seems to be up to institutions with no economic interest in the drug to reveal any risks taking it may entail. Second, there are questions about the evaluation methods, at least with regard to the duration of clinical trials in relation to the types of populations involved in them. Instead of issuing a full approval, there would be progressive measures, adjusted on the basis of specifc studies by researchers related to the time and population factors. Conclusion All our analyses tend to point up the diversity of types of knowledge that are actualized in the laboratory, even though the refocusing on the object of research is a permanent fact of life and is largely supported by the social conditions of the production of knowledge. There also emerges from the analysis a concern for crosspollination that is refected in the importation of resources from other felds – a process particularly well illustrated by the reconstruction of the networks of actors – so that the production of knowledge does not dry up as a result of the contraction of the object of specialization. One cannot help thinking of the metaphor that arose frequently in the discourse of the researchers during interviews in these laboratories regarding the drying up of the tumour, starving it by sabotaging the development of the blood vessels that proliferate to feed it. Yet while our analyses highlight the importance of the circulation of knowledge into the laboratory from the outside, they also show the importance of movement in the opposite direction. By continually increasing collaboration with others, the laboratory expands and shares in a “hybrid” knowledge, a sort of arrangement stemming from negotiations involving researchers and authorities. The analyses enabled us to discern a cleavage in the categories of knowledge; how the categories are reframed to respond to the needs of the laboratories; and a systemic circularity in the pathways of knowledge creation and circulation. Indeed, in these types of knowledge, different disciplines are called upon along with different levels of knowledge – from basic to technical and clinical – the connections between which vary depending on context. These contextual elements also bring into play variations in the role of this plurality, given the references to competitive 305 Catherine Garnier situations, which are far from rare in this scientifc milieu. The analyses also revealed antagonistic social practices and constructs marked by the relationship between the knowledge and power of the actors in the three laboratories and refecting a highly competitive survival situation. The construction of laboratory knowledge is not a function of the scientifc context alone. It is harnessed, changed, transmitted, distorted, used, and conjured away in response to variations in economic, clinical, technological, and cultural circumstances. Indeed, these preliminary results reveal the presence in the laboratories of what Knorr Cétina and Latour call “plural knowledge,” which might just as well be called “multidimensional knowledge. They highlight the diversity of institutions concerned, disciplines the researchers belong to and types of knowledge present. Time amplifes this diversifcation and the increase in collaborations that can fuctuate as circumstances change over the course of a career, since the way knowledge is subdivided is a result of differential principles of action. Finally, in the chronology of the substances, the circulation of knowledge may seem chaotic. In fact, depending on the type of substance, its pathway may well be marked by both uncertainty and the absence of data.
