It is often the case that one preparation is not enough to control hypertension. In such a case, several different drugs are introduced into the therapy.

Both drugs lower blood pressure, so when taken at the same time, they will make the effect stronger. At the beginning of treatment (after the first doses), excessive pressure drops may also be felt when changing the body position from lying to standing.
