ACE Inhibitors

• Angiotensin-converting enzyme inhibitors (ACE) are a type of high blood pressure medication that treats heart failure symptoms in addition to lowering blood pressure. This medication may be prescribed for someone who has chest pain or diabetes because it reduces chest pain and does not interfere with blood sugar levels. ACE inhibitors work by expanding blood vessels and letting blood flow more easily. This lowers high blood pressure and enables the heart to work more efficiently.
  
  

Diuretics

• Diuretics are also known as "water pills." This type of high blood pressure medication causes the body to get rid of extra fluid and salt through the urine. Diuretics may raise blood sugar levels in diabetics. The doctor may change a diabetic's diet or adjust insulin medication levels to keep blood sugar levels normal. It is important to increase potassium intake while taking a diuretic because it could decrease the level of potassium in the body.
  
  

Beta-Blockers

• Beta-blockers lower high blood pressure and treat heart arrhythmias and angina pectoris, which is chest pain caused by an insufficient amount of oxygen circulating through the heart. People with diabetes may need to check their blood sugar levels more often because this type of high blood pressure medication could hide the warning signs of low blood sugar levels.
  
  

Calcium Channel Blockers

• Calcium channel blockers, also called "calcium antagonists," can suppress calcium moving through the heart and vessel cells. This medication treats abnormal heart rhythms and chest pain.
  
  

Alpha-Blockers

• This type of high blood pressure medication decreases the frequency of nerve impulses to blood vessels in the heart. This allows blood to flow easily, causing blood pressure to lower. Alpha-blockers can also treat prostate problems.
  
  

Vasodilators

• Vasodilators relax the muscles in the blood vessels, causing them to open and let blood flow more easily. This type of high blood pressure medication also treats heart failure and pulmonary hypertension, which is high blood pressure in the lungs.
  
  

Angiotensin-2 Receptor Antagonists

• This medication prevents a chemical called angiotensin II from affecting the heart and blood vessels leading to the heart. The blood vessels are able to open up, letting blood flow through them freely and keeping blood pressure down.
