Question

Enumerate Alpha blockers and explain their therapeutic uses. (1+3)

Q104 marksShort Answers

Answer

Alpha blockers: Prazosin, Terazosin, Doxazosin (alpha-1 selective); Phenoxybenzamine (non-selective, irreversible); Tamsulosin (alpha-1A selective, uroselective).

Therapeutic uses:

  • Hypertension — Prazosin/Terazosin/Doxazosin reduce peripheral resistance by blocking vascular alpha-1 receptors.
  • Benign prostatic hyperplasia — Tamsulosin relaxes bladder neck/prostatic smooth muscle (alpha-1A selectivity minimizes vascular/hypotensive effects), relieving obstructive urinary symptoms.
  • Pheochromocytoma — Phenoxybenzamine, given pre-operatively to control catecholamine-driven hypertension before tumour resection.
