An oral nonopioid analgesic is often sufficient for acute treatment of mild to moderate migraine pain without severe nausea or vomiting. A triptan is the drug of choice for treatment of moderate to severe migraine in most patients without vascular disease. Treatment of pain when it is still mild to moderate in intensity improves headache response and reduces the risk of recurrence.

The FDA has approved Prestalia (Symplmed), an oral fixed-dose combination of the dihydropyridine calcium channel blocker amlodipine (Norvasc, and generics) and a new salt form of the angiotensin-converting enzyme (ACE) inhibitor perindopril, for treatment of hypertension in patients not adequately controlled on monotherapy or already taking both drugs, and in those just starting therapy who are likely to need multiple drugs to control their blood pressure. The new salt form (perindopril arginine) is more stable and has a longer shelf-life than perindopril erbumine (Aceon, and generics). Two other ACE inhibitor/calcium channel blocker combinations, benazepril/amlodipine (Lotrel, and generics) and trandolapril/verapamil ER (Tarka, and generics), have been available in the US for many years.

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.

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.
