概括
微阵列 (MAP) 贴片提供了一种新的透皮骨质疏松症治疗方法,绕过口服双酸盐 (BPs) 常见的胃肠道问题. 在体内研究表明,MAP显著改善骨密度,并减少骨质疏松症大鼠的多孔性.
科学领域:
- 生物材料科学 生物材料科学
- 药理学 药理学是指药理学的学科.
- 整形外科 整形外科 整形外科
背景情况:
- 骨质疏松症影响全球超过2亿人,口服双酸盐 (BPs) 是主要治疗方法.
- 口服BP的胃肠道 (GI) 副作用限制了患者的遵守.
- 微阵列 (MAP) 补丁技术为通过皮肤递送药物提供了一个潜在的解决方案,减轻肠道刺激.
研究的目的:
- 评估溶解和形成水凝的MAPs在通过皮肤输送阿伦德罗尼酸 (ALN) 和升酸 (RDN) 的疗效.
- 评估MAP技术作为骨质疏松症管理的患者友好的替代方案.
主要方法:
- 为骨质疏松症药物开发溶解和形成水凝的MAP.
- 在骨质疏松症雌性Sprague Dawley大鼠的体内测试,由双边卵巢切除 (OVX) 诱导.
- 对血清和骨性酸酶水平,骨体积和毛孔性的分析.
主要成果:
- 在OVX大鼠中,MAP治疗显著改善了骨体积,并减少了OVX大鼠大腿骨的远端化和转化中的多孔性.
- 在接受MAP治疗的老鼠中,平均骨体积增加到55.04%,而在OVX对照组中为47.16%.
- 在接受MAP治疗的老鼠中,毛孔性降至44.30%,而在OVX对照组中 (远端形) 则降至52.84%.
结论:
- MAP技术显示出作为骨质疏松症管理的新,患者友好的替代品的潜力.
- 通过MAP通过皮肤传递有效地克服与口服双酸盐相关的胃肠道副作用.
- 这项概念验证研究支持每周治疗骨质疏松症的MAP.

Drug Delivery: Miscellaneous Routes
329
Drug delivery methods like oral inhalation, nasal sprays, transdermal patches, eye drops, intravitreal injection, and rectal administration provide localized effects with reduced toxicity.
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.

Drug Distribution: Tissue Binding
2.6K
Upon entering the systemic circulation, drugs can distribute into the interstitial and intracellular fluid of various tissue cells. This distribution is facilitated by the binding of drugs to different cellular components within tissues, which may lead to drug accumulation in specific areas. Drugs bound to tissue components serve as reservoirs that release free drugs back into the system, prolonging the drug's overall action. However, this accumulation can also result in local toxicity.
