An oral nonopioid analgesic may be sufficient for
treatment of mild to moderate migraine without severe
nausea or vomiting. A triptan is the drug of choice for
treatment of moderate to severe migraine. Use of
a triptan early in an attack when pain is still mild to
moderate in intensity improves headache response
and reduces recurrence rates.

The FDA has announced changes in the labeling of simvastatin to reduce the risk of myopathy. These changes include limiting the use of the 80-mg maximum dose to patients who have been taking it for 12 months or more without evidence of myopathy and new recommendations for use of simvastatin with other drugs. Simvastatin is available alone (Zocor, and others) and in combination with ezetimibe (Vytorin) and with niacin (Simcor).

A recent letter to the editor of the Annals of Internal Medicine documented a single case of myopathy apparently due to an interaction between simvastatin (Zocor, and others) and green tea. Since it became available generically, simvastatin has surpassed atorvastatin (Lipitor) as the best selling statin. As such, it is probably the most common cause of statin-induced myopathy, which is often a result of drug interactions.

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.

Patients with frequent, severe or disabling migraine headaches may benefit from taking a drug to prevent the attacks. Beta-blockers traditionally have been the prophylactic treatment of choice, but in recent years some antiepileptic drugs such as valproate (Depakote, and others) and topiramate (Topamax) have also been used for this indication. Valproate was approved by the FDA for such use in 1996. Now topiramate has also been approved.
Safety of Aggressive Statin Therapy

New guidelines from The National Cholesterol Education Program recommend, as a therapeutic option, lowering treatment goals for LDL cholesterol (LDL-C) from <100 mg/dL to <70 mg/dL for patients at very high risk for coronary heart disease and from 130 mg/dL to <100 mg/dL for those at moderately high risk. A likely consequence of these recommendations is increased use of statins and use of higher doses with a concomitant increase in adverse effects.

Changes caused by one drug in the absorption, distribution, metabolism or excretion of another may lead to a pharmacokinetic adverse drug interaction (DN Juurlink et al, JAMA 2003; 289:1652). Additive drug interactions, such as vasodilation caused by both sildenafil (Viagra) and nitrates, can also have adverse effects.

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).
