❤️ Inotropic Drug Used in Heart Failure
✅ Answer: (b) Dobutamine
📖 What is an Inotropic Agent?
Ino = Muscle or fiber
Tropic = Affecting
👉 An inotropic drug changes the force of heart muscle contraction.
A positive inotropic agent increases the heart’s pumping strength.
💊 What is Dobutamine?
Dobutamine is a positive inotropic drug that stimulates β1-receptors in the heart.
It helps:
- Increase the force of heart contraction
- Improve cardiac output
- Treat severe acute heart failure and cardiogenic shock
👉 Dobutamine is given only by intravenous (IV) infusion because it has a very short duration of action.
📖 What is Intravenous (IV)?
Intra = Within
Venous = Vein
👉 Intravenous means the medicine is given directly into a vein.
❌ Why Other Options Are Wrong?
(a) Digoxin
❌ It is also a positive inotropic drug but can be given orally as well as intravenously.
(c) Nifedipine
❌ Calcium channel blocker used mainly for hypertension and angina, not an IV inotropic agent.
(d) Atenolol
❌ Beta-blocker that reduces heart rate and workload; it is not an inotropic drug.
Acute Heart Failure → Need stronger heart pumping → IV Dobutamine
📌 Disclaimer: For nursing exam preparation only. The question likely intends “inotropic” (not “nootropic”), as dobutamine is an inotropic drug used in heart failure.
