β€οΈ Inotropic Drug Used in Heart Failure
β Answer: (b) Dobutamine
π What is an Inotropic Agent?
Ino = Muscle or fiber
Tropic = Affecting
π An inotropic drug changes the force of heart muscle contraction.
A positive inotropic agent increases the heart’s pumping strength.
π What is Dobutamine?
Dobutamine is a positive inotropic drug that stimulates Ξ²1-receptors in the heart.
It helps:
- Increase the force of heart contraction
- Improve cardiac output
- Treat severe acute heart failure and cardiogenic shock
π Dobutamine is given only by intravenous (IV) infusion because it has a very short duration of action.
π What is Intravenous (IV)?
Intra = Within
Venous = Vein
π Intravenous means the medicine is given directly into a vein.
β Why Other Options Are Wrong?
(a) Digoxin
β It is also a positive inotropic drug but can be given orally as well as intravenously.
(c) Nifedipine
β Calcium channel blocker used mainly for hypertension and angina, not an IV inotropic agent.
(d) Atenolol
β Beta-blocker that reduces heart rate and workload; it is not an inotropic drug.
Acute Heart Failure β Need stronger heart pumping β IV Dobutamine
π Disclaimer: For nursing exam preparation only. The question likely intends “inotropic” (not “nootropic”), as dobutamine is an inotropic drug used in heart failure.
