title: Use of aliskiren in a 'real-life' model of hypertension management:  analysis of national Web-based drug-monitoring system in Italy.
abstract: BACKGROUND
  In Italy, prescriptions of the direct renin inhibitor aliskiren (aliskiren) to high-risk hypertensive patients must be electronically filled by specialized physicians only when at least two antihypertensive drug classes (independently of the dosages), fails to normalize blood pressure (BP) levels.
  
  
  OBJECTIVE
  To analyze the effects of the addition of aliskiren 150-300 mg daily to antihypertensive therapy in a population of high cardiovascular risk hypertensive patients with uncontrolled BP levels.
  
  
  METHODS
  Clinical data were derived from patients included in the national Web-based drug-monitoring system. Follow-up visits were required for measuring BP levels, and collecting data on drug safety and tolerability.
  
  
  RESULTS
  Between March 2009 and February 2010, aliskiren was prescribed by 6464 specialized physicians to 11 511 treated, uncontrolled hypertensive patients (47.6% women, aged 68.0 ± 11.1 years, BMI 28.4 ± 4.9 kg/m) with organ damage or comorbidities. During 6-month observation, only a few drug-related side-effects were reported (n = 33). At the entry and 1-month follow-up visits (n = 8197; 70.6%), BP levels were 158.9 ± 16.8 and 142.1 ± 15.2 mmHg for SBP and 90.8 ± 9.6 and 83.1 ± 8.5 mmHg for DBP, respectively. At 6-month (n = 4907; 42.3%), SBP and DBP levels were 137.9 ± 13.9 and 81.3 ± 8.0 mmHg, respectively. A consistent reduction in the use of all classes of concomitant antihypertensive drugs was recorded.
  
  
  CONCLUSIONS
  Although data derived from national registries need to be interpreted with caution, the Italian Web-based drug-monitoring system provided information on 'real-life' use of aliskiren in hypertension. In this uncontrolled, high-risk treated hypertensive population, SBP and DBP levels recorded during treatment with aliskiren were consistently lower than those recorded at entry visits in a context of a very low rate of reported side-effects.
