| ACE inhibitors | *SLOWS DOWN AND SLOWLY DIALATES ALL VESSLES OF THE BODY.* All end in PRIL Can cause a dry cough Decreases Blood Pressure |
| Beta Blockers | **SLOWS HR DOWN AND MAKES IT STRONGER** Dialates vessels a little Decreases tension on blood vessels ALL END WITH LOL |
| Potassium | Balences normal BP and minimizes the possibilities of heart diseases and hypertension. |
| Digoxin | *Decreases Heart Rate *Watch Potassium Levels *Toxic Effects- can lower HR to low *Side Effects-dizziness, and feeling of being Faint Normal Blood Lab values is 0.5-2.0 (above 2.0 is ditoxcity) PT may see yellow or halo lights |
| Nitroglyerin | DILATES!! Loses strength in 3 months SIDE EFFECTS - FLUSHING, THROBBING HEADACHE, INCREASED HR, RISSINESS, LIGHT HEADEDNESS ***Sit down or Lay down*** If blurred vision, persistent headache, or dry mouth occurs call doctor! |

| Atropine | **SPEEDS UP HR** (increases HR at the SA node) |
| Niacin | *Lowers Cholesterol *Gets Flushed and Red over body, muscular pain, constipation and LIVER PROBLEMS **DON'T TAKE WITH OTHER MEDS** |
