Efficacy & effects

Improvement in blood pressure control for hypertension

  • Hypertension
View approved original text

In hypertensive patients for whom blood pressure is not adequately controlled by monotherapy with losartan, additional treatment may be necessary. It is recommended to consider combination therapy or the addition of other medications to enhance blood pressure control. These approaches help effectively lower blood pressure and reduce the risk of cardiovascular complications. Managing blood pressure is crucial for improving overall health and protecting the heart and blood vessels. Therefore, it is necessary to take appropriate measures to manage blood pressure stably.
