Question

The chemical class of propranolol is _______

• A. Phenoxyalkylamine
• B. Aryloxypropanolamine
• C. Imidazoline
• D. Benzyl amine

Hint:

Propranolol is a beta blocker chemically classified as an aryloxypropanolamine.

Answer 1

The Correct Option is B

Concept:
Propranolol is a non-selective beta adrenergic blocker used in hypertension, angina, arrhythmias, and other cardiovascular conditions.

Step 1: Chemical structure idea.
Propranolol contains an aromatic ring linked through an oxygen atom to a propanolamine side chain.

Step 2: Chemical class.
Because of this structural feature, propranolol belongs to the aryloxypropanolamine class.

Step 3: Pharmacological importance.
The aryloxypropanolamine structure is important for beta-blocking activity.

Step 4: Checking other options.
Phenoxyalkylamine is a different class.
Imidazoline is associated with drugs acting on imidazolinealpha receptors.
Benzyl amine is not the correct class of propranolol.

Step 5: Final answer.
Therefore, propranolol belongs to aryloxypropanolamine class. \[ \boxed{\text{Aryloxypropanolamine}} \]
