Statins form the cornerstone of pharmaceutical cardiovascular disease prevention. However, despite very effective statin intervention, the majority of events remain unpreventable. In some cases statin therapy alone is insufficient to achieve adequate lipid levels whereas other patients are unable to tolerate statins. This calls for additional treatment options. Niacin has a long history of success in reducing low-density lipoprotein cholesterol and triglycerides, and increasing high-density lipoprotein cholesterol. It was the first lipid-lowering drug to demonstrate a reduction in cardiovascular events, and remains the only one that has consistently shown benefits on surrogate outcomes when added to background therapies of other lipid-lowering drugs, including statins. Niacin's uptake in clinical practice has been less successful due to its side-effect profile, most notable being flushing. The uncovering of the mechanism by which flushing is induced, together with the development of a prostaglandin D(2) receptor inhibitor (laropiprant) which reduces this downstream flushing effect of niacin, has sparked new promise in therapeutic lipid management. It provides an additional treatment option into managing lipid abnormalities. The uptake in clinical practice of the niacin-laropiprant combination will depend on the relative improvements experienced by the patient in the side-effect profile compared to other treatment options, as well as on the the keenly-awaited outcome studies currently underway. Until these data become available guidelines and recommendations are unlikely to change and niacin's position in therapeutic cardiovascular risk prevention will be determined by clinician opinion and experience, and patient preferences.
他汀类药物是药物预防心血管疾病的基石。然而,尽管他汀类药物干预非常有效,但大多数心血管事件仍无法预防。在某些情况下,仅使用他汀类药物治疗不足以达到足够的血脂水平,而其他患者则无法耐受他汀类药物。这就需要更多的治疗选择。烟酸在降低低密度脂蛋白胆固醇和甘油三酯以及提高高密度脂蛋白胆固醇方面有着长期成功的历史。它是第一种证明能减少心血管事件的降脂药物,并且仍然是唯一一种在添加到包括他汀类药物在内的其他降脂药物的背景治疗中时,始终显示出对替代指标有益的药物。由于其副作用,尤其是潮红,烟酸在临床实践中的应用并不成功。潮红诱导机制的发现,以及一种能减少烟酸下游潮红效应的前列腺素D2受体抑制剂(拉罗匹仑)的开发,为治疗性血脂管理带来了新的希望。它为管理脂质异常提供了另一种治疗选择。烟酸-拉罗匹仑组合在临床实践中的应用将取决于与其他治疗选择相比,患者在副作用方面的相对改善情况,以及目前正在进行的备受期待的结局研究。在这些数据可用之前,指南和建议不太可能改变,烟酸在治疗性心血管疾病风险预防中的地位将由临床医生的意见和经验以及患者的偏好来决定。
