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.


Pharmacologic Management of Heart Failure Caused by Systolic Dysfunction - Article

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.


Managing Hypertension Using Combination Therapy - Article

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.


Preventing Congestive Heart Failure - Article

ABSTRACT: The morbidity, mortality and health care costs associated with congestive heart failure make prevention a more attractive public health strategy than treatment. Aggressive management of etiologic factors, including hypertension, coronary artery disease, valvular disease and excessive alcohol intake, can prevent the left ventricular remodeling and dysfunction that lead to heart failure. Early intervention with angiotensin converting enzyme inhibitors in patients with chronic left ventricular dysfunction can prevent, as well as treat, the syndrome. Several intervention strategies in patients with acute myocardial infarction can slow or prevent the left ventricular remodeling process that antedates congestive heart failure. The primary care physician must be alert to the need for aggressive intervention to reduce the burden of heart failure syndrome on the patient and on society.


Angiotensin-II Receptor Antagonists: Their Place in Therapy - Article

ABSTRACT: Angiotensin-II receptor antagonists (or blockers) are a newer class of antihypertensive agents. These drugs are selective for angiotensin II (type 1 receptor); unlike angiotensin-converting enzyme inhibitors, they do not inhibit bradykinin metabolism or enhance prostaglandin synthesis. Angiotensin-II receptor antagonists are well tolerated. Cough occurs much less often with these agents than with angiotensin-converting enzyme inhibitors, and they do not adversely affect lipid profiles or cause rebound hypertension after discontinuation. Clinical trials indicate that angiotensin-II receptor antagonists are effective and safe in the treatment of hypertension. Their use in congestive heart failure and renal disease is under investigation.


A Rational Approach to the Treatment of Hypertension in Special Populations - Article

ABSTRACT: Hypertension in blacks is usually characterized by low renin, expanded volume and sensitivity to salt. Diuretics are the preferred initial therapy, but response to calcium channel antagonists is also good. The blood pressure response to monotherapy with beta blockers or angiotensin-converting enzyme (ACE) inhibitors is blunted, but this effect is abolished with concomitant use of diuretics. The two major types of hypertension in older persons are isolated systolic hypertension and combined systolic and diastolic hypertension. Strong data support the treatment of combined hypertension in patients 60 to 79 years of age and isolated systolic hypertension in patients 60 to 96 years of age. Diuretics and long-acting dihydropyridine calcium channel antagonists are the recommended initial therapies for isolated systolic hypertension. More studies are necessary before recommendations can be made about the treatment of combined hypertension in patients 80 years of age and older.
