Abstract

Introduction. Les interactions entre plantes et médicaments conventionnels représentent un risque réel et grandissant pour la santé de nos patients. Pourtant, la phytothérapie et ses interactions potentielles est un domaine peu présent dans la formation des médecins en Belgique. Objectifs. Le but de ce travail est d'identifier les interactions plante-médicament dangereuses et les interactions impliquant les plantes fréquemment consommées dans notre pratique, et de mettre en évidence les ressources disponibles pour le médecin généraliste afin de conseiller adéquatement ses patients. Méthodologie. La méthodologie comporte une recherche de littérature et une enquête sur la consommation de produits à base de plantes chez les patients de notre pratique de médecine générale ayant consulté durant les mois de décembre et janvier 2017. Résultats. Comme les médicaments, les plantes peuvent être à l'origine d'interactions pharmacocinétiques et pharmacodynamiques. La littérature scientifique concernant les interactions plantes-médicaments repose sur de faibles niveaux de preuves à part pour le millepertuis. Les interactions dangereuses impliquent le cytochrome P450 3A4, dont le millepertuis est un puissant inducteur et le pamplemousse un puissant inhibiteur. Les autres interactions dangereuses impliquent des médicaments dont la marge thérapeutique ou toxique est étroite comme par exemple les anticoagulants, les antirétroviraux, les antiépileptiques, la digoxine, les agents anticancéreux et les immunosuppresseurs. Le développement d'une interaction ne repose pas uniquement sur la plante et le médicament consommés mais également sur certaines caractéristiques propres à l'individu. Dans notre étude, septante-trois pourcents des quatre-vingt-trois participants consommaient ou avaient consommé des produits à base de plantes. Trente-et-une interactions potentielles ont été mises en évidence, dont trois interactions sévères. Afin de conseiller le mieux possible son patient, le médecin généraliste peut s'appuyer sur la littérature, sur les "interaction checker" disponibles en ligne, sur sa collaboration avec le pharmacien; en outre, une des missions du médecin généraliste est de faire avancer les connaissances dans ce domaine en notifiant les interactions à !'Agence Fédérale des Médicaments et Produits de Santé.

Abstract

Quatrième de couverture : "Un guide de référence sur les principales drogues d'origine végétale, leurs usages dans l'histoire et dans le présent, les pays où elles sont cultivées, leurs effets et leurs dangers éventuels ainsi que les aspects légaux de leur production ou consommation. Au fil de son histoire, l'homme a appris à connaître les espèces végétales qui agissent sur son psychisme, lui permettant d'entrer dans des états modifiés de conscience et de perception, de s'élever au-dessus de sa condition, de planer, voire d'entrer en communication avec dieux ou esprits. Les chamans de diverses civilisations ont fait appel à ces plantes pour communiquer avec la Nature, poser un diagnostic et trouver le remède adapté à une maladie; les artistes y ont puisé créativité et inspiration; les curieux explorent des mondes intérieurs et les métamorphoses des sens. Les psychotropes provoquent des effets psychiques et physiques tels que des perturbations des perceptions, des hallucinations ou des modifications de l'humeur ou de la pensée. Sensation de bien-être, euphorie, sentiment de se surpasser : certaines sont addictives, d'où leur classement dans la liste des stupéfiants prohibés. Mais quelques psychotropes présentent aussi un immense potentiel thérapeutique encore peu exploité, suscitant un intérêt croissant dans les milieux scientifiques. Le cannabis et ses constituants (THC et CBD) sont par exemple efficaces contre les douleurs et les spasmes de la sclérose en plaques ; les composants des champignons hallucinogènes, contre la dépression et le stress post-traumatique; le LSD, pour apaiser les malades en fin de vie terrifiés par la mort. Depuis la première édition de cet ouvrage en 2002, beaucoup de choses se sont passées : l'interdiction de la sauge divinatoire en Suisse et en Belgique, du kratom en Suisse et de l'ayahuasca en France, mais aussi la possibilité d'avoir accès au cannabis thérapeutique en Suisse et en France. Il y a eu aussi l'arrivée de nouvelles drogues comme l'hortensia, phénomème éphémère, ou le changa, version fumée de l'ayahuasca d'Amérique du Sud, qui séduit toujours plus d'Occidentaux. L'histoire de ces drogues, le hasard de leur découverte, leurs effets et modes d'action, leurs dangers et leurs cadres légaux sont présentés dans cet ouvrage actualisé avec de nombreuses anecdotes étonnantes, des onguents aphrodisiaques des sorcières du Moyen Âge aux buveurs d'urine de consommateurs d'amanites tue-mouches, en passant par le culte qu'une secte moderne voue à des crapauds à la peau hallucinogène..."

Abstract

There are not studies about herb-drug interactions despite the widespread use of herbal medicines. There are several qualities of “natural” products which contain different amounts of herbal active constituents. There is no process for systematic evaluation of botanical supplement products for possible interactions with prescription medications. That’s why, the study of the interactions between these products and the drugs were difficult. In the literature, there are two types of interactions between plants and drugs which are described. On the one hand, pharmacodynamic interactions occur when the pharmacological action of the plant cause an increase or a decrease in the pharmacological action of the drug. On the other hand, pharmacokinetic interactions occur when vegetable component is responsible for the changes in absorption, metabolism or elimination of the drug.
Clinically important interactions appear to involve effects on drug metabolism via cytochromes P450 isonzymes. We will study clinically significant herb-drug predictions of interactions were confirmed in vivo whereas others weren’t. So, it is important to promote the notification of all suspect interactions in order to prevent side effects in a better way. Continued education if consumers and healthcare professionals about the potential herb-drug interactions is required to ensure further interactions that do not occur Les produits à base de plantes ne font pas l’objet d’études approfondies qui permettraient une connaissance des interactions avec les médicaments. Il existe plusieurs conditionnements de produits «naturels» à base de plantes avec des teneurs en substances actives différentes. Ces produits « naturels » ne subissent pas des contrôles de qualité aussi rigoureux que les médicaments. C’est pourquoi, l’étude des interactions entre ces produits et les médicaments a été difficile. Dans la littérature, il existe deux types d’interactions entre plantes et médicaments qui sont décrits. D’une part, les interactions d’ordre pharmacodynamique sont observées quand l’action pharmacologique de la plante a pour effet d’augmenter ou de diminuer l’action pharmacologique du médicament en agissant a niveau des récepteurs. D’autre part, les interactions d’ordre pharmacocinétique sont observées lorsqu’un constituant végétal est responsable des changements au niveau de l’absorption, du métabolisme ou de l’élimination du médicament. Les principales interactions pharmacocinétiques revêtant d’une importance clinique seront dues aux variations d’activités enzymatiques des CYP450 induites par la présence d’inducteur ou d’inhibiteur au sein de la plante. Ce travail a pour objet l’étude des interactions entre les produits à base de plantes non médicamenteux et les médicaments au niveau des CYP450. Nous verrons que certaines prédictions d’interactions ont été confirmées in vivo alors que d’autres pas. Il est donc important d’encourager le rapportage de tous les cas « suspects » d’interactions afin de mieux prévenir les effets secondaires. La vigilance s’impose surtout avec els médicaments à faible index thérapeutique. Lors de la délivrance de médicaments, le pharmacien jour un rôle essentiel dans le conseil et la prévention des interactions.

Abstract

This book focuses on efficacy, toxicity, drug interactions, and abnormal clinical laboratory tests resulting from the use of herbal remedies. Although a few herbal remedies are safe and have efficacy (for example saw palmetto), many herbal remedies are toxic. This book guides in the interpretation of abnormal test results in otherwise healthy subjects due to use of herbal remedies. Chapters focus on interactions between herbals and pharmaceuticals, sources of contamination in herbal supplements, and analytical techniques used in the investigation of herbal remedies.

Abstract

Plants have served mankind as an important source of foods and medicines. While we all consume plants and their products for nutritional support, a majority of the world population also rely on botanical remedies to meet their health needs, either as their own “traditional medicine” or as “complementary and alternative medicine”. From a pharmaceutical point of view, many compounds obtained from plant sources have long been known to possess bio/pharmacological activities, and historically, plants have yielded many important drugs for human use, from morphine discovered in the early nineteenth century to the more recent paclitaxel and artemisinin. Today, we are witnessing a global resurgence in interest and use of plant-based therapies and botanical products, and natural products remain an important and viable source of lead compounds in many drug discovery programs.This Special Issue on “Plant Natural Products for Human Health” compiles a series of scientific reports to demonstrate the medicinal potentials of plant natural products. It covers a range of disease targets, such as diabetes, inflammation, cancer, neurological disease, cardiovascular disease, liver damage, bacterial, and fungus infection and malarial. These papers provide important insights into the current state of research on drug discovery and new techniques. It is hoped that this Special Issue will serve as a timely reference for researchers and scholars who are interested in the discovery of potentially useful molecules from plant sources for health-related applications.
