Answer

Classification of beta blockers

BasisClassExamples
SelectivityNon-selective (β1 + β2)Propranolol, Timolol
Cardioselective (β1)Atenolol, Metoprolol
With additional α1-blocking activityLabetalol, Carvedilol
Intrinsic sympathomimetic activityWith ISA (partial agonist)Pindolol, Acebutolol
Without ISAPropranolol, Atenolol

Propranolol — mechanism, uses, contraindications

  • Mechanism: propranolol → non-selective β1/β2 receptor blockade → ↓heart rate, ↓contractility, ↓renin release (β1) and blocks β2-mediated bronchodilation/vasodilation.
  • Uses: hypertension, angina, arrhythmias, post-myocardial infarction, migraine prophylaxis, essential tremor, anxiety, hyperthyroidism (symptomatic control).
  • Contraindications: bronchial asthma/COPD (β2 blockade causes bronchospasm), severe bradycardia/heart block, decompensated heart failure, severe peripheral vascular disease, and used cautiously in diabetics (masks hypoglycemia symptoms).
