Most commonly employed antihypertensive agents are normally cleared because few of them rely exclusively on renal excretion. Therefore dose selection is not appreciably altered for propanolol, hydralazine, clonidine, alpha methyldopa, gaunethidine, and others. Most dialysis patients are given several water soluble vitamins, iron, phosphate binder, calcium, some form of vitamin D, and usually an antipruritc agent, a slleping pill, and often an antihypersentive.
