Most recent guidelines recommend a BP goal of 140/90 mm Hg. For patients ≥60 years old without diabetes
or chronic kidney disease, one guideline recommends
150/90 mm Hg both as the drug treatment initiation
threshold and treatment target; this higher target is
controversial, except in patients ≥80 years old.

Renal colic is a common problem in emergency departments. Stones <5 mm in diameter often pass spontaneously; stones >10 mm in diameter generally do not. The usual treatment for stones that do not pass is ureteroscopy with laser lithotripsy or shockwave lithotripsy. Some clinicians have suggested that off-label use of an oral alpha-adrenergic blocker such as tamsulosin (Flomax, and others) or calcium channel blocker such as nifedipine (Procardia XL, and others) could be tried first, with or without a corticosteroid. Both adrenoreceptors and calcium channels may have a role in the contractility of the ureter.

Serious adverse interactions between drugs continue to be reported. Many of these are due to inhibition or induction of cytochrome P450 (CYP) enzymes, particularly CYP3A4. CYP3A is thought to be involved in the metabolism of more than 50 percent of currently prescribed drugs.2 CYP3A4, which is more abundantly expressed than CYP3A5, accounts for most CYP3A activity in vivo.

The importance of adequate control of hypertension in preventing organ damage and death is well established, but the choice of drugs is still controversial. Three recent drug trials, one supporting initial therapy with a diuretic, the second favoring an angiotensin converting enzyme (ACE) inhibitor, and the third showing equivalence between a calcium-channel blocker and an angiotensin-receptor blocker (ARB) have intensified the debate.

The ability of grapefruit juice to increase serum concentrations of drugs was first discovered during a study of the effect of ethanol on felodipine (Plendil) pharmacokinetics. Double-strength grapefruit juice used to disguise the taste of ethanol resulted in higher than expected serum concentrations of felodipine (DG Bailey et al, Clin Invest Med 1989; 12:357).

Drugs are used both to prevent and treat migraine symptoms. The effectiveness of such use can be difficult to evaluate, even with double-blind controlled trials, because migraine is episodic, response to placebo is frequent, and patients vary in response to a given agent (KMA Welch, N Engl J Med, 329:1476, 1993; SD Silberstein and RB Lipton, Neurology, 44 suppl 7:S6, Oct 1994).

Drugs for Hypertensive Emergencies
The Medical Letter on Drugs and Therapeutics • April 7, 1989; (Issue 789)
Hypertensive emergencies include hypertensive encephalopathy, intracranial hemorrhage with hypertension, aortic dissection, acute pulmonary edema with hypertension, acute cardiac ischemia with hypertension,...
Hypertensive emergencies include hypertensive encephalopathy, intracranial hemorrhage with hypertension, aortic dissection, acute pulmonary edema with hypertension, acute cardiac ischemia with hypertension, malignant hypertension and severe hypertension after vascular surgery; hypertensive crisis due to pheochromocytoma or occurring during pregnancy is not discussed in this review. Although immediate reduction of blood pressure is necessary in hypertensive emergencies, an excessive decrease may cause stroke, myocardial infarction or visual changes. Most experienced clinicians aim initially for a 25% decrease in mean arterial pressure, with a minimum diastolic pressure of 100 mm Hg; lower pressures may be indicated for patients with aortic dissection.

Many fermented foods contain tyramine as a byproduct formed by the bacterial breakdown of the amino acid tyrosine; it can also be formed by para-hydroxylation of phenylethylamine or dehydroxylation of DOPA and dopamine.

Vasodilators are widely used for treatment of congestive heart failure (CHF) that has not responded adequately to diuretics and digitalis. Vasodilator drugs redistribute blood volume in patients with heart failure, lowering pressure and reducing volume in the failing left ventricle, which leads to increased cardiac output, decreased pulmonary capillary wedge pressure, and improved exercise tolerance. Since the last Medical Letter review of this subject (Volume 26, page 115, 1984), some additional data have become available.
