Blood pressure medicines lower pressure but don't fix the root cause of why it was high.

“What becomes obvious when you work on the front line is that medication controls pressure, but it doesn't reverse the disease. An ACE inhibitor reduces angotensin signaling which lowers vascular resistance and brings pressure down. A diuretic forces the kidneys to excrete sodium which reduces blood volume. A calcium channel blocker relaxes arterial smooth muscle which drops resistance mechanically. All of these types of medication work and they save lives, but they don't fix why the pressure was high in the first place.”
