Abstract
Aim: To discuss two aspects that can be used to improve the adherence to therapy in patients with arterial hypertension (AH): 1) which of the angiotensin II receptor blockers (ARBs) provides the highest adherence rates; 2) how various factors influence adherence rates.
Material and methods: An analysis of one of the world's largest clinical practice databases, Truven Health Analytics MarketScan (currently Merative MarketScan), was performed. The analysis included data on patients of both sexes aged 30 to 65 years who had been diagnosed with uncomplicated AH (at least once between March 1, 2012 and January 1, 2018) and prescribed monotherapy with one of ARBs. The exclusion criteria were heart failure and the treatment with two or more ARBs (simultaneously or sequentially) during the treatment period. Ultimately, the study included 717,099 patients with uncomplicated AH, who were divided into four groups based on the prescribed drug: azilsartan (n=4276), candesartan (n=6023), losartan (n=586,857), and valsartan (n=119,943). Adherence to treatment was evaluated by two parameters: duration of continuous therapy and medication possession ratio (MPR). The individual effect of each factor (specific ARB used for therapy, patient gender, age, initial ARB dose, patient co-payment per day of treatment) on the adherence to treatment was assessed using a regression analysis.
Results: The adherence to the ARB therapy was generally high. The MPR was the lowest in the azilsartan group and the highest in the candesartan group. However, the parameters that potentially influenced both the MPR and the duration of continuous therapy (patient's gender and age, initial ARB dose, co-payment size) differed significantly between the groups receiving different ARBs. The regression analysis showed that both adherence parameters and the duration of continuous therapy were higher in patients receiving candesartan than in patients receiving azilsartan, losartan or valsartan, when the effect on the adherence of other factors available for study (age, gender, initial dose of the drug, and the absolute size of co-payment for a day of therapy) was excluded. The lowest adherence to therapy was observed in the azilsartan treatment group (p<0.01).
Conclusion: The study provided data for comparing the adherence of patients with uncomplicated AH to the therapy with different ARBs. Further study of adherence to treatment will provide additional data that will allow an optimal selection of drugs for the treatment of AH in patients with potentially poor adherence.
