In a first step, the first lines of anti-hypertensive medication will be the angiotensin-converting enzyme inhibitors (ACEI) captopril and enalapril, or the angiotensin receptor blocker (ARB) losartan, or calcium channel blockers (CCB), nifedipine, diltiazem and verapamil, or diuretics, the thiazide-type diuretic hydrochlorthiazide or chlortalidone, or beta-blockers, atenolol, in selected cases. In a second step, if BP is not controlled, a combination of two drug classes will be tried. If BP is not achieved, in a third step, a third drug class will be added. All of these anti-hypertensive drugs are available in the PPP. In a fourth step, when BP control is not yet obtained, other antihypertensive drugs will be requested from the city public health department, preferably low costs drugs such as clonidine, spironolactone, hydralazine and amlodipine. During this phase, a consultation with a hypertension specialist physician will be provided. The combined use of ACEI and ARB will be avoided. For individuals with chronic kidney disease, initial antihypertensive treatment will include an ACEI or ARB. This includes all chronic kidney disease patients with hypertension independent of diabetes and race.
