Persistence with treatment in newly treated middle-aged patients with essential hypertension.

Background: Antihypertensive agents have been found to decrease morbidity and/or mortality associated with cardiovascular disease (CVD). Surveys have shown that hypertension has been diagnosed in many patients but remains uncontrolled. One factor may be the lack of persistence to treatment.

Persistence and determinants of statin therapy among middle-aged patients for primary and secondary prevention.

Aims: Statins have been shown to significantly reduce morbidity and mortality in patients with coronary artery disease (CAD), and also in patients with dyslipidaemia when statins are taken regularly. Middle-aged patients have the highest level of forecasting benefit and little is known about persistence rate of these therapies in a real-life setting. The objective was to evaluate the persistence rate of middle-aged patients initiating a statin therapy and its relation with several determinants for primary and secondary prevention.

Stereoselective disposition of the antiarrhythmic agent mexiletine during the concomitant administration of caffeine.

Caffeine consumption is extensive in industrialized countries and its role in drug-drug interactions is often overlooked. CYP1A2, the major cytochrome P450 isoform involved in the metabolism of caffeine, has also been implicated in the formation of N-hydroxymexiletine, the major metabolite of mexiletine. Therefore, the objective of this study was to assess the effects of a clinically relevant dosage of caffeine on the stereoselective disposition of mexiletine.
