ARBs | Reduce the action of Ang II at its receptor by blocking it, causing vasodilation. | Azilsartan, eprosartan, losartan, irbesartan, olmesartan, valsartan, telmisartan, candesartan | Eprosartan possesses sympathoinhibitory [15]. |
Calcium channel blockers | Prevents calcium influx into heart and arterial cells by blocking the calcium channels. | Nifedipine, amlodipine, felodipine, nicardipine, isradipine, nisoldipine, diltiazem, verapamil | |
Diuretics | Induce excretion of body salt and water by aiding in the movement of sodium into the urine. | Chlorothiazide,# indapamide,# metolazone,# chlorthalidone,# hydrochlorothiazide,# bumetanide,* ethacrynic acid,* furosemide,* torsemide,* spironolactone,& amiloride,& eplerenone,& triamterene& | They can be used as monotherapy or in combination. Three types of diuretics are in clinical use: thiazide,# loop,* and potassium sparing& |

β-blockers | Block beta receptors | Atenolol, pindolol, metoprolol, propranolol, bisoprolol, timolol, labetalol, carvedilol, acebutolol | Not generally recommended as first-line drugs |
Renin-inhibitors | Inhibit the enzyme renin from triggering a process that helps regulate BP. | Aliskiren | Have an additive effect when used with diuretics |
Centrally acting antihypertensives (α-2 agonist) | Stimulate presynaptic alpha2-adrenergic receptors in the brain stem, which reduces SNA | Methyldopa, clonidine, guanfacine |
