Conventional Treatments for Hypertension


The key to controlling blood pressure is intimately tied to a healthy lifestyle and, more so, to the following:

  • A healthy diet        
  • Physically activity
  • Maintaining a healthy weigh


  • Quitting smoking
  • Managing stress
 Even with medication, one should always seek to make healthy lifestyle changes to better control hypertension.


Blood pressure medicines work in different ways to lower blood pressure. Some remove extra fluid and salt from the body to lower blood pressure. Others slow down the heartbeat or relax and widen blood vessels. Often, two or more medicines work better than one. Which category of medication your doctor prescribes depends on your stage of high blood pressure and whether you also have other medical problems.

 Drug Class
Mode of Action Common Side Effects 


Thiazide diuretics "water pills"

Activates the kidneys to eliminate sodium and water, thus reducing blood volume, that in turn, reduces blood pressure
  • Increased urination
  • Erection problems in some men
  • Leg cramps
  • Fatigue
  • Intense and sudden foot pain
Beta blockersCauses the heart to beat slower and with less force. The heart then pumps less blood through your blood vessels and this leads to reduced blood pressure
  • Asthma symptoms
  • Cold hands and feet
  • Depression
  • Erection problems
  • Insomnia and sleep problems
Angiotensin-converting enzyme
Keeps the body from making a hormone called angiotensin II. This hormone normally causes blood vessels to narrow. When it is not produced, the blood vessels relax and pressure within then is reduced
  • A dry
  • Hacking cough that doesn't go away
  • Skin rash
  • Loss of taste
Angiotensin II Receptor Blockers (ARBs)
These prevent (block) the angiotensin II hormone from acting on the  blood vessels. As a result, blood vessels relax and widen, and your blood pressure goes down
  • dizziness
Calcium channel blockersPrevents calcium from re-entering the muscle cells of your heart and blood vessels. This allows blood vessels to relax and may help the heart to pump more slowly.

Grapefruit juice interacts with some calcium channel blockers, increasing blood levels of the medication and putting you at higher risk of side effects.

  • Constipation
  • Dizziness
  • Headache
  • Irregular or very rapid heartbeat (palpitations)
  • Swollen ankles
Renin inhibitors
Aliskiren (Tekturna)

Slows  the production of renin, an enzyme produced by your kidneys that increases blood pressure. Tekturna works by reducing the ability of renin to begin this process.
  • Cough
  • Diarrhea
  • Stomach pain
  • Heartburn
  • Rash
Alpha BlockersReduce nerve impulses that cause blood vessels to tighten. Blood moves more freely and pressure is reduced
Alpha-Beta BlockersReduce nerve impulses that cause blood vessels to tighten. They also slow the heartbeat like beta blockers
Nervous System InhibitorsPrevent signaling  from the brain to increase heart rate and narrow blood vessels
VasodilatorsRelax the muscles of the arteries, thereby reducing blood pressure

Hypertension that is difficult to control (Resistant hypertension)

Resistant hypertension is high blood pressure that remains stubbornly high despite taking at least three different types of high blood pressure drugs, one of which should be a diuretic. Resistant hypertension is blood pressure that's resistant to treatment. People who have controlled high blood pressure but are taking four different types of medications at the same time to achieve that control also are considered to have resistant hypertension.

Having resistant hypertension doesn't mean your blood pressure will never get lower. A change in approach to treatment may be warranted.
