If blood pressure still remains high, then the dose of diuretics or beta-blockers is increased or a calcium channel blocker, ACE inhibitor, angrotension II blocker, or combination drug replaces or is added to the treatment plan.

ACE inhibitors can be administered with diuretics (qv), cardiac glycosides, -adrenoceptor blockers, and calcium channel blockers. Clinical trials indicate they are generally free from serious side effects. The effectiveness of enalapril, another ACE inhibitor, in preventing patient mortaUty in severe (Class IV) heart failure was investigated. In combination with conventional dmgs such as vasodilators and diuretics, a 40% reduction in mortaUty was observed after six months of treatment using 2.5—40 mg/d of enalapril (141). However, patients complain of cough, and occasionally rash and taste disturbances can occur. 

Patients having high plasma renin activity (PRA) (>8 ng/(mLh)) respond best to an ACE inhibitor or a -adrenoceptor blocker those having low PRA (<1 ng/(mLh)) usually elderly and black, respond best to a calcium channel blocker or a diuretic (184). -Adrenoceptor blockers should not be used in patients who have diabetes, asthma, bradycardia, or peripheral vascular diseases. The thiazide-type diuretics (qv) should be used with caution in patients having diabetes. Likewise, -adrenoceptor blockers should not be combined with verapamil or diltiazem because these dmgs slow the atrioventricular nodal conduction in the heart. Calcium channel blockers are preferred in patients having coronary insufficiency diseases because of the cardioprotective effects of these dmgs. 

In the treatment of hypertension, ACE inhibitors are as effective as diuretics, (3-adrenoceptor antagonists, or calcium channel blockers in lowering blood pressure. However, increased survival rates have only been demonstrated for diuretics and (3-adrenoceptor antagonists. ACE inhibitors are approved for monotherapy as well as for combinational regimes. ACE inhibitors are the dtugs of choice for the treatment of hypertension with renal diseases, particularly diabetic nephropathy, because they prevent the progression of renal failure and improve proteinuria more efficiently than the other diugs.

Patients with asymptomatic left ventricular systolic dysfunction and hypertension should be treated with P-blockers and ACE inhibitors. Those with heart failure secondary to left ventricular dysfunction and hypertension should be treated with drugs proven to also reduce the morbidity and mortality of heart failure, including P-blockers, ACE inhibitors, ARBs, aldosterone antagonists, and diuretics for symptom control as well as antihypertensive effect. In African-Americans with heart failure and left ventricular systolic dysfunction, combination therapy with nitrates and hydralazine not only affords a morbidity and mortality benefit, but may also be useful as antihypertensive therapy if needed.66 The dihydropyridine calcium channel blockers amlodipine or felodipine may also be used in patients with heart failure and left ventricular systolic dysfunction for uncontrolled blood pressure, although they have no effect on heart failure morbidity and mortality in these patients.49 For patients with heart failure and preserved ejection fraction, antihypertensive therapies that should be considered include P-blockers, ACE inhibitors, ARBs, calcium channel blockers (including nondihydropyridine agents), diuretics, and others as needed to control blood pressure.2,49... 

Patients with diabetes and hypertension should initially be treated with either P-blockers, ACE inhibitors, ARBs, diuretics, or calcium channel blockers. There is a general consensus that therapy focused on RAAS inhibition by ACE inhibitors or ARBs may be optimal if the patient has additional cardiovascular risk factors such as left ventricular hypertrophy or chronic kidney disease.2,3,59,67... 

ACE inhibitors and angiotensin-receptor blockers (ARB) have definite benefits in patients with nephropathy and are believed to have renoprotective effects in most patients. Due to their ability to cause an initial bump in serum creatinine, these agents should be used cautiously when employed in combination with the calcineurin inhibitors. The dihydropyridine calcium channel blockers have demonstrated an ability to reverse the nephrotoxicity associated with cyclosporine and tacrolimus (Table 52-8). In general, antihypertensive therapy should focus on agents with proven benefit in reducing the progression of cardiovascular disease and should be chosen on a patient-specific basis.55 See Chapter 2 for further recommendations for treating HTN. 

Many different drug classes have shown to cause hypotension and orthostatic reactions and drugs for cardiovascular conditions, psychoactive medicines and polypharmacy, can all have this side effect (Box 5.15). Among the most frequently used drugs in the elderly are diuretics, ACE-inhibitors, angiotensin II antagonists, calcium channel blockers and antidepressants.

Another type of antihypertensive agent is a calcium channel blocker. This was discussed under amlodipine (no. 6) in Section 3.6. Finally, angiotension-converting enzyme (ACE) inhibitors are used in severe... 

Other methods for reducing hypertension include ACE inhibitors and calcium channel blockers these are discussed in subsequent chapters. 

The six main drug classes used, worldwide, for blood pressure lowering treatment are diuretics, jS-blockers, calcium channel blockers (CCB), ACE inhibitors, angiotensin II (All) receptor blockers and a-adrenergic blockers. In some parts of the world, reserpine and methyldopa are also frequently used. 

Their antihypertensive efficacy is comparable to that of (3-adrenergic blockers and angiotensin-converting enzyme (ACE) inhibitors. The choice of a calcium channel blocker, especially for combination therapy, is largely influenced by the effect of the drug on cardiac pacemakers and contractility and coexisting diseases, such as angina, asthma, and peripheral vascular disease.
