The female mosquito is infected by gametocytes, the sexual stages of the malaria parasite, when they take a blood meal from an infected person. Male and female gametocytes then fuse to form zygotes (ookinetes), which embed in the gut wall A as oocysts and then undergo further development in the insect for 6–12 days. The intensity of malaria transmission in an area is the rate at which people are inoculated with malaria parasites by infected mosquitoes. The proportion of infected mosquitoes in a locality refects the capacity of the vectors to transmit malaria (vectorial capacity) and the number of infected and infectious humans in the area. Lowering the infectivity of infected persons to mosquito vectors contributes to reducing malaria transmission and eventually to reducing the incidence and prevalence of the disease. Experience with major interventions, such as use of insecticide-treated nets and artemisinin-based combination therapy, suggests that effective transmission-reducing interventions reduce mortality and even morbidity in most situations (1–4). Relation between entomological inoculation rate and parasite prevalence (on the assumption that no infections are treated) Parasite prevalence (%) 100 80 60 40 20 0 0. Early, effective treatment of a malaria blood infection with any antimalarial medicine will reduce gametocytaemia by eliminating the asexual blood stages from which gametocytes derive. The faster the clearance of asexual blood parasites, the greater the reduction in infectivity. The potent anti-infective properties of artemisinins result partly from rapid clearance of parasites. Effective treatment of the asexual blood infection alone abolishes infectivity to mosquitoes. Infectivity can be lowered either by a direct effect on gametocytes (gametocytocidal effect; primaquine) or on the parasite developmental stages in the mosquito (sporontocidal effect; antifols, atovaquone) or by killing feeding mosquitoes (endectocidal effect; avermectins). Sulfadoxine–pyrimethamine in fact increases gametocyte carriage, but it also reduces the infectivity of drug-sensitive parasites. Artemisinins are the most potent gametocytocidal drugs of those currently used to treat acute malaria (6–11). They kill young gametocytes, preventing new infective gametocytes from entering the circulation, but they have less effect on mature gametocytes that may 130 be present in the circulation at the time of treatment (6). The 8-aminoquinoline primaquine acts on mature gametocytes rapidly, reducing their transmissibility to mosquitoes and accelerating gametocyte clearance (12–20).

Vertical axes show the proportions of fed anopheline mosquitoes that were infected. Oocyst formation (upper graph) and sporozoite formation (lower graph) assessed from blood sampled 48 h after a dose of primaquine. Primaquine given with an artemisinin derivative is shown in green, and primaquine given with no antimalarial medicine or a non-artemisinin derivative is shown in red. The size of the circle is proportional to the number of patients in each group (shown within). In areas of low-to-moderate transmission The most direct consequences of lowering parasite infectivity by the use of medicines are seen in areas of low transmission, where symptomatic patients contribute signifcantly to the infectious reservoir. Reducing infectiousness has a signifcant impact on malaria transmission and thus the prevalence of infection and the incidence of disease. In areas of high-transmission In high-transmission areas, infected but asymptomatic people constitute an important part of the infectious reservoir. Even though treated cases (mainly children) have higher densities of gametocytes and infectivity is positively related to gametocyte density, symptomatic patients comprise only a minority of the infective reservoir (21–23). In high-transmission settings, a considerable reduction in transmission rates is required to reduce parasite prevalence (and incidence of disease). Adding transmission-blocking drugs to antimalarial treatment is not cost–effective.

Several antiarrhythmics are harmful for people with heart failure and generally should be avoided. If you have a heart rhythm disturbance, your health care provider can use other medicines to manage it. If you have heart failure, your health care provider will probably want you to avoid certain antiarrhythmics, such as quinidine, disopyramide, procainamide, dronedarone, and fecainide. Although you may have read some encouraging claims about these therapies, there is no evidence that they improve heart failure. We do know that the ingredients in some alternative therapies interfere with the action of heart failure medicines and may have other harmful actions. Some natural or man-made products containing the following substances may interfere with or harmfully affect the intended effects of certain medicines used to treat heart failure: Ephedra (ma huang) Chinese herbs Ephedrine byproducts Hawthorne (cratageus) products Additionally, the following substances can interact with a blood thinner you may be taking: Garlic Gingko Ginseng Coenzyme Q-10 If you wish to try alternative or herbal therapies, please talk to your health care providers about it. Ask them the following questions: Will this alternative or herbal Has this alternative or herbal therapy interfere with my heart therapy been tested for safety failure medicines? Tell your health care provider about any natural medicines or alternative or herbal therapies that you are taking. Beware of extravagant claims about the benefts of alternative or herbal therapies. List each of your own medicines, their doses, and number of times each day you take each medicine on your cards. The fol- lowing tips can help you: Get a pillbox labeled with the days of the week and times of day. Ask a family member or visiting health care provider to help you fll the box, if needed. Put the list on the refrigerator or other place where you will easily see it every day. Do I need to take my heart failure medicines even if I feel well, am breathing easily, and do not have swelling? Remember that some of these medicines block the production or action of stress hormones (substances that make heart failure worse). So even if you are feeling well, breathing easily, and do not have swelling, your body needs the medicines.

At the same time they now acknowledge the primacy of public health in drug policy, the centrality of the harm reduction approach and the fact that there is a spirit of reform in the air. Key steps towards reform will include: * Moves must be made to establish meaningful international data collection. These include questions concerning the impact of drug control on human rights, confict, crime, corruption, development and security—as well as the more familiar public health measures. It will support a more effective critique of current successes and failings, which will help inform and guide more serious discussion of alternative approaches. This would echo the trend in drug policy generally away from a criminal justice focus to a more public health focus (including the location of the drug brief in domestic government, for example Spain, moving from Home Affairs to Health). Novak, ‘The United Nations and Drug Policy, Towards a human rights based approach’ (in: ‘The diversity of international law: Essays in honour of Kalliopi K Koufa’), 2009. It would move beyond the polarised legalisation/ prohibition debates of the past, instead talking about shared principles and aims, exploring options and potential outcomes, critiquing the failings of the drugs war and explaining in clear practical terms how phased moves towards regulation could bring benefits to individual countries and to the wider global community. Bewley-Taylor, ‘Emerging policy contradictions between the United Nations drug control system and the core values of the United Nations’, International Journal of Drug Policy, 2005, Vol. Novak, ‘The United Nations and Drug Policy: Towards a human rights based approach’ (in: ‘The diversity of international law: Essays in honour of Kalliopi K Koufa’, pages 449–477), 2009 191 1 2 3 Introduction Five models for regulating drug supply The practical detail of regulation 4 5 6 Making a regulated system happen Regulated drug markets in practice Appendices Appendix 2 Current legal production frameworks for opium, coca, cannabis and pharmaceuticals The regulated production of psychoactive drugs requires less attention than supply issues. There are already a large range of models in place for regulated production of plant and or pharmaceutical based drugs, from which lessons can be learned. In many cases, given that the same drugs are being considered, production for non-medical use will merely require expansion of existing frameworks. The following consider- ation of existing legal and regulated production of opium/heroin, coca/ cocaine, and cannabis will help demonstrate how this could happen. Legal production of opium 140 A signifcant proportion, almost half, of global opium production is legally produced for processing into opiate based medicines. Any country can cultivate, produce and trade in licit opium, under the 140 Licit opium production accounted for more than half of global opium production until the recent bumper harvests in Afghanistan. As of 2001 there were eighteen countries that do; of these, four, (China, Korea, India and Japan) cultivate opium poppy for the production of raw opium, although only India exports it. Once harvested and collected, the pods and stalks are then sent to a factory to be chemically‘washed’. India is the exception to this rule: it is the only sanctioned exporter of opium gum. Whilst not without problems, this range of scenarios demonstrates that opium production is possible in a range of different environments. Iran and some Central Asian republics utilise confscated illicit opium for their domestic medical markets. Mansfeld notes that: Whilst previously, these countries had been satisfed with using seized opium for their domestic opiate needs, in recent years they have sought to sell seized opiates, or products derived from them internationally. Diversion to illicit market The levels of leakage into the illicit market vary greatly from country to country. Country quotas are set using offcial estimates of interna- tional demand using fgures from the past two years’ consumption. However, according to offcial fgures, ‘even in these countries only 24% of moderate to severe pain-relief 145 need was being met’. There is a real issue here regarding the access of pain relief by developing world countries that do not have a licence to grow poppies. International legal framework The international licensing control system seeks to permit and regulate legitimate production and use, while at the same time prevent diversion to the illicit market for non-medical use. Domestic legal framework arrangements Each of the countries that grows opium poppies for export has its own set of legal frameworks in order to prevent diversion into the illicit market.
