Which of the following does not affect secretion of renin?
High-Yield Explanation
It is now possible to inhibit the secretion or the effects of renin in a variety of ways. Inhibitors of prostaglandin synthesis such as indomethacin and -adrenergic blocking drugs such as propranolol reduce renin secretion. The peptide pepstatin and newly developed renin inhibitors such as enalkiren prevent renin from generating angiotensin I. Angiotensin-conveing enzyme inhibitors (ACE inhibitors) such as captopril and enalapril prevent conversion of angiotensin I to angiotensin II. Saralasin and several other analogs of angiotensin II are competitive inhibitors of the action of angiotensin II on both AT1 and AT2 receptors. Losaan (DuP-753) selectively blocks AT1 receptors, and PD-123177 and several other drugs selectively block AT2 receptors Ref: Ganong's Review of Medical Physiology 23rd edition, Chapter 39.
