Medications for Migraine Prophylaxis - Article
ABSTRACT: Sufficient evidence and consensus exist to recommend propranolol, timolol, amitriptyline, divalproex, sodium valproate, and topiramate as first-line agents for migraine prevention. There is fair evidence of effectiveness with gabapentin and naproxen sodium. Botulinum toxin also has demonstrated fair effectiveness, but further studies are needed to define its role in migraine prevention. Limited evidence is available to support the use of candesartan, lisinopril, atenolol, metoprolol, nadolol, fluoxetine, magnesium, vitamin B2 (riboflavin), coenzyme Q10, and hormone therapy in migraine prevention. Data and expert opinion are mixed regarding some agents, such as verapamil and feverfew; these can be considered in migraine prevention when other medications cannot be used. Evidence supports the use of timed-release dihydroergotamine mesylate, but patients should be monitored closely for adverse effects.
ABSTRACT: Combination therapy of hypertension with separate agents or a fixed-dose combination pill offers the potential to lower blood pressure more quickly, obtain target blood pressure, and decrease adverse effects. Antihypertensive agents from different classes may offset adverse reactions from each other, such as a diuretic decreasing edema occurring secondary to treatment with a calcium channel blocker. Most patients with hypertension require more than a single antihypertensive agent, particularly if they have comorbid conditions. Although the Joint National Committee guidelines recommend diuretic therapy as the initial pharmacologic agent for most patients with hypertension, the presence of "compelling indications" may prompt treatment with antihypertensive agents that demonstrate a particular benefit in primary or secondary prevention. Specific recommendations include treatment with angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, diuretics, beta blockers, or aldosterone antagonists for hypertensive patients with heart failure. For hypertensive patients with diabetes, recommended treatment includes diuretics, beta blockers, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and/or calcium channel blockers. Recommended treatment for hypertensive patients with increased risk of coronary disease includes a diuretic, beta blockers, angiotensin-converting enzyme inhibitors, and/or calcium channel blocker. The Joint National Committee guidelines recommend beta blockers, angiotensin-converting enzyme inhibitors, and aldosterone antagonists for hypertensive patients who are postmyocardial infarction; angiotensin-converting enzyme inhibitors and angiotensin receptor blockers for hypertensive patients with chronic kidney disease; and diuretic and angiotensin-converting enzyme inhibitors for recurrent stroke prevention in patients with hypertension.
ABSTRACT: Several large clinical trials conducted over the past decade have shown that pharmacologic interventions can dramatically reduce the morbidity and mortality associated with heart failure. These trials have modified and enhanced the therapeutic paradigm for heart failure and extended treatment goals beyond limiting congestive symptoms of volume overload. Part II of this two-part article presents treatment recommendations for patients with left ventricular systolic dysfunction. The authors recommend that, if tolerated and not contraindicated, the following agents be used in patients with left ventricular systolic dysfunction: an angiotensin-converting enzyme inhibitor in all patients; a beta blocker in all patients except those who have symptoms at rest; and spironolactone in patients who have symptoms at rest or who have had such symptoms within the past six months. Diuretics and digoxin should be reserved, as needed, for symptomatic management of heart failure. Other treatments or treatment programs may be necessary in individual patients.
ABSTRACT: Diastolic heart failure, a major cause of morbidity and mortality, is defined as symptoms of heart failure in a patient with preserved left ventricular function. It is characterized by a stiff left ventricle with decreased compliance and impaired relaxation, which leads to increased end diastolic pressure. Signs and symptoms are similar to those of heart failure with systolic dysfunction. The diagnosis of diastolic heart failure is best made with Doppler echocardiography. Based on current knowledge, pharmacologic treatment of diastolic heart failure should focus on normalizing blood pressure, promoting regression of left ventricular hypertrophy, avoiding tachycardia, treating symptoms of congestion, and maintaining normal atrial contraction when possible. Diuretic therapy is the mainstay of treatment for preventing pulmonary congestion, while beta blockers appear to be useful in preventing tachycardia and thereby prolonging left ventricular diastolic filling time. Angiotensin-converting enzyme inhibitors and angiotensin-receptor blockers may be beneficial in patients with diastolic dysfunction, especially those with hypertension. Evidence from adequately powered randomized controlled trials, however, is not available yet. The outcomes of ongoing clinical trials may provide much-needed information to move from intuitive treatment to therapy based on evidence that matters: decreased morbidity and mortality and improved quality of life.
ABSTRACT: Risk factors for stroke should be evaluated in patients who have had a transient ischemic attack. Blood pressure, lipid levels, and diabetes mellitus should be controlled. When applicable, smoking cessation and weight loss also are important. Angiotensin-converting enzyme inhibitor therapy may help prevent stroke. Aspirin is the treatment of choice for stroke prevention in patients who do not require anticoagulation. Clopidogrel is an alternative therapy in patients who do not tolerate aspirin. Atrial fibrillation, a known cardioembolic source (confirmed thrombus), or a highly suspected cardioembolic source (e.g., recent large myocardial infarction, dilated cardiomyopathy, mechanical valve, rheumatic mitral valve stenosis) are indications for anticoagulation.

ABSTRACT: Heart failure caused by systolic dysfunction affects more than 5 million adults in the United States and is a common source of outpatient visits to primary care physicians. Mortality rates are high, yet a number of pharmacologic interventions may improve outcomes. Other interventions, including patient education, counseling, and regular self-monitoring, are critical, but are beyond the scope of this article. Angiotensin-converting enzyme inhibitors and beta blockers reduce mortality and should be administered to all patients unless contraindicated. Diuretics are indicated for symptomatic patients as needed for volume overload. Aldosterone antagonists and direct-acting vasodilators, such as isosorbide dinitrate and hydralazine, may improve mortality in selected patients. Angiotensin receptor blockers can be used as an alternative therapy for patients intolerant of angiotensin-converting enzyme inhibitors and in some patients who are persistently symptomatic. Digoxin may improve symptoms and is helpful for persons with concomitant atrial fibrillation, but it does not reduce cardiovascular or all-cause mortality. Serum digoxin levels should not exceed 1.0 ng per mL (1.3 nmol per L), especially in women.
ABSTRACT: Coronary artery disease is the leading cause of mortality in the United States. In patients who have had a myocardial infarction or revascularization procedure, secondary prevention of coronary artery disease by comprehensive risk factor modification reduces mortality, decreases subsequent cardiac events, and improves quality of life. Options for secondary prevention include medical therapy and surgical revascularization in the form of coronary artery bypass grafting or percutaneous coronary intervention. Medical therapy focuses on comprehensive risk factor modification. Therapeutic lifestyle changes (including weight management, physical activity, tobacco cessation, and dietary modification) improve cardiac risk factors and are universally recommended by evidence-based guidelines. Treatment of hypertension and dyslipidemia reduces morbidity and mortality. Recommendations for persons with diabetes mellitus generally encourage glucose control, but current evidence has not shown reductions in mortality with intensive glucose management. Aspirin, angiotensin-converting enzyme inhibitors, and beta blockers reduce recurrent cardiac events in patients after myocardial infarction. Surgical revascularization by coronary artery bypass grafting is recommended for those with significant left main coronary artery stenosis, significant stenosis of the proximal left anterior descending artery, multivessel coronary disease, or disabling angina. Percutaneous coronary intervention may be considered in select patients with objective evidence of ischemia demonstrated by noninvasive testing.
