    1. Dihydropyridine Calcium Channel Blockers
      1. Dihydropyridines are primarily active at vascular Smooth Muscle

    2. Nifedipine (Procardia) is prototype for class
  3. Contraindications
    1. Avoid in Diabetes Mellitus (may increase Proteinuria)
  4. Drug Interactions
    1. Clarithromycin
      1. Increases Calcium Channel Blocker levels via CYP3A4 inhibition especially with Dihydropyridines and over age 65 years
        1. Provokes Hypotension and Bradycardia
        2. Risk of Acute Kidney Injury (often requiring hospitalization)

      1. Dosing
        1. 2.5-5mg PO qd (MAX 10mg qd)
      2. Advantages
        1. Does not exacerbate Left Ventricular Dysfunction
    3. Felodipine
    4. Nimodipine (Nymalize)
  6. Preparations: Parenteral (Hypertensive Emergency)
    1. Background
      1. Counter Cerebral Vessel spasm (e.g. early Subarachnoid Hemorrhage, CVA)
    2. Clevidipine (Cleviprex)
    3. Nicardipine
  7. Adverse Effects
    1. See Calcium Channel Blocker
    2. Peripheral Edema (Norvasc)
      1. Occurs more commonly in women
      2. Occurs more commonly on Norvasc doses >5 mg
      3. Adding ACE Inhibitor to regimen decreases edema

Amlodipine (C0051696)

Definition (MSH) A long-acting dihydropyridine calcium channel blocker. It is effective in the treatment of ANGINA PECTORIS and HYPERTENSION.
Definition (CHV) a drug used to treat high blood pressure and chest pain (angina)
Definition (NCI) A synthetic dihydropyridine and a calcium channel blocker with antihypertensive and antianginal properties. Amlodipine inhibits the influx of extracellular calcium ions into myocardial and peripheral vascular smooth muscle cells, thereby preventing vascular and myocardial contraction. This results in a dilatation of the main coronary and systemic arteries, decreased myocardial contractility, increased blood flow and oxygen delivery to the myocardial tissue, and decreased total peripheral resistance. This agent may also modulate multi-drug response (MDR) activity through inhibition of the p-glycoprotein efflux pump.
Definition (CSP) long-acting dihydropyridine calcium channel blocker; it is effective in the treatment of angina pectoris and hypertension.
