Hypertension remains one of the most unmet medical needs of this century. While many drugs are available for treating hypertension, efforts are still insufficient to find potent therapeutic agents since cause for hypertension in all patients is not the same. Angiotensin-converting enzyme inhibitors (ACEIs) have emerged as an important class of drugs in the treatment of hypertension, congestive heart failure (CHF), protenuric renal disease, myocardial infarction and stroke. This class of drugs blocks the conversion of angiotensin I to angiotensin II and prevents bradykinin breakdown. However, the lack of specificity of ACEIs leads to the frequent side effects like cough and angio-oedema. Recently developed, specific non-peptide and orally active angiotensin receptor blockers (ARBs) have become the prime therapeutics as they alone or coadministration with ACE inhibitors can control the renin angiotensin disorders. This review explores recent developments in the design, synthesis, and structural modifications of ACE inhibitors as well as angiotensin receptor blockers.
