A four-in-one pill containing "ultra-low doses" of different medications can provide better blood pressure control than standard drug treatment, a new clinical trial from Australia shows.
A doctor's presence during a blood pressure reading triggers a "fight or flight" response that can affect the results, say researchers who studied the effect by measuring nerve activity.
Two long used types of blood pressure drugs are equally effective, but the less popular one seems to have fewer side effects, according to a large "real-world" study.
