موسعات الأوعية.

تعالج موسعات الأوعية الدموية مجموعة متنوعة من الحالات، بما في ذلك ارتفاع ضغط الدم. اكتشف المزيد حول هذه الفئة من الأدوية.

By Mayo Clinic Staff

موسعات الأوعية الدموية هي أدوية تساعد على فتح (توسيع) الأوعية الدموية. وتؤثر على العضلات في جدران شرايينك وأوردتك، مما يقي العضلات والجدران من التضيق.

نتيجة لذلك، يدفق الدم بسهولة أكبر خلال أوعيتك. لا يحتاج قلبك لضخ الدم بالقوة نفسها، مما يقلل من ضغط الدم الخاص بك.

بعض الأدوية المستخدمة لعلاج ارتفاع ضغط الدم، مثل حاصرات قنوات الكالسيوم — التي تمنع دخول الكالسيوم عبر جدران الأوعية الدموية — توسع أيضا الأوعية الدموية. ولكن موسعات الأوعية الدموية التي تعمل مباشرة على الأوعية الدموية هي الهيدرالازين والمينوكسيديل.

استخدام موسعات الأوعية الدموية

يصف الأطباء موسعات الأوعية لتجنب أو لعلاج أو لتحسين الأعراض في حالات مختلفة، مثل:

  • ارتفاع ضغط الدم
  • ارتفاع ضغط الدم أثناء الحمل أو عند الأطفال (مقدمات الارتجاع أو الارتجاع)
  • فشل القلب
  • ارتفاع ضغط الدم الذي يؤثر على شرايين الرئتين (فرط ضغط الدم الرئوي)

التحذيرات والآثار الجانبية

موسعات الأوعية المباشرة أدوية قوية لا تُستخدَّم بشكلٍ عام إلا في حالة عدم تحكم الأدوية الأخرى في ضغط الدم لديك على نحوٍ ملائم.

تحتوي هذه الأدوية على عدد من الآثار الجانبية، تتطلب بعضها تناول أدوية أخرى لعلاجها.

تشتمل الآثار الجانبية على ما يلي:

  • ضربات القلب السريعة (تسرع القلب)
  • خفقان القلب
  • الاحتفاظ بالسوائل (الوذمة)
  • الغثيان
  • القيء
  • تورد الوجه
  • الصداع
  • نمو الشعر المفرط
  • ألم المفصل
  • آلام الصدر
