Hypertension, a worldwide epidemic at present, is not a disease in itself rather it is an important risk factor for serious cardiovascular disorders including myocardial infarction, stroke, heart failure, and peripheral artery disease. Though numerous drugs acting via different mechanism of action are available in the market as conventional formulations for the treatment of hypertension but they face substantial challenges regarding their bioavailability, dosing and associated adverse effects which greatly limit their therapeutic efficacies. Various studies have demonstrated that nanocarriers can significantly increase the drug bioavailability thereby reducing the frequency of dosing in addition to minimizing toxicity associated with high dose of the drug. The present review provides an insight into the challenges associated with the conventional antihypertensive formulations and need for oral nanoparticulate systems in order to overcome problems associated with conventional formulations. Hypertension has circadian pattern of blood pressure, therefore chronotherapeutics can play a decisive role for the treatment, and however, nanoparticulate system can play major role in hypertension management. Future prospective for particulate nanocarriers in drug delivery for hypertension includes chronotherapeutics and emerging technique like gene therapy which is also covered in the review.
高血压是目前全球范围内的一种流行病,它本身并非一种疾病,而是包括心肌梗死、中风、心力衰竭和外周动脉疾病在内的严重心血管疾病的重要危险因素。尽管市场上有许多通过不同作用机制发挥作用的药物作为治疗高血压的传统制剂,但它们在生物利用度、给药剂量和相关不良反应方面面临重大挑战,这极大地限制了它们的治疗效果。各种研究表明,纳米载体可以显著提高药物的生物利用度,从而减少给药频率,同时将与高剂量药物相关的毒性降至最低。本综述深入探讨了传统抗高血压制剂面临的挑战以及口服纳米颗粒系统的必要性,以克服与传统制剂相关的问题。高血压具有昼夜血压模式,因此时辰治疗学在治疗中可以发挥决定性作用,然而,纳米颗粒系统在高血压管理中可以发挥主要作用。颗粒纳米载体在高血压药物递送中的未来前景包括时辰治疗学和基因治疗等新兴技术,本综述也涵盖了这些内容。
