Efficacy, safety, and tolerability of antihypertensive therapy with aliskiren/amlodipine in clinical practice in Austria. The RALLY (Rasilamlo long lasting efficacy) study
Aim: This observational study evaluated the efficacy and tolerability of 3-month aliskiren/amlodipine therapy under outpatient conditions.
Methods: This Austria-wide observational study included 579 hypertensive patients (566 [98 %] who could be analyzed biometrically) under the care of 140 physicians. The average age of the patient collective was 64 ± 11 years and the mean duration of hypertension was 10 ± 7 years. Regarding 92 % of the study participants, an antihypertensive therapy already existed. Efficacy was assessed in accordance with the Austrian hypertension guidelines while tolerability was evaluated on the basis of adverse events. A descriptive physician judgment based on efficacy, tolerability, and compliance was available for 539 patients (95 %). Office blood pressure values were used for the evaluation.
Results: On average, the systolic and diastolic blood pressures were reduced from 161 ± 14 to 135 ± 10 mmHg and 93 ± 9 to 81 ± 6 mmHg, respectively. Blood pressure values of < 140/90 mmHg and < 130/80 mmHg were achieved in 56 and 7 % patients, respectively. A subgroup analysis of 242 patients (43 %) with diabetes mellitus and/or renal disease, as well as those with a high cardiovascular risk, demonstrated nearly identical results compared to the total population. Overall, 44 adverse events were documented in 41 patients, and physicians reported that 94 % of patients were compliant in a final survey on evaluation of therapy.
Conclusion: The fixed-dose combination of aliskiren/amlodipine provided clinically relevant blood pressure reductions along with good tolerance and compliance. During the 3-month duration of observation under outpatient conditions, it was seen that aliskiren and amlodipine reduced the systolic and diastolic blood pressures on average by 26 and 13 mmHg, respectively.
