Nicardipine (Cardene) - Uses, Dose, Side effects

Nicardipine (Cardene) belongs to the class of dihydropyridine calcium channel blockers.

Nicardipine Uses:

  • Angina:

    • It is used in the treatment of chronic stable angina (oral immediate-release product only).
  • Hypertension:

    • It is indicated for treating hypertension (oral immediate/ sustained release or intravenous forms).
    • Intravenous administration may be used for the short term when oral treatment cannot be given.

Guideline recommendations:

The 2017 Guideline for the Prevention, Detection, Evaluation, and Management of High Blood Pressure in Adults recommends if single-agent therapy is to be given in the absence of comorbidities, thiazide-like diuretics or dihydropyridine calcium channel blockers are preferred due to prevention of heart failure and stroke.

ACE inhibitors and ARBs can also be given as monotherapy. Combination therapy is initially preferred in high-risk patients (such as stage 2 hypertension, atherosclerotic cardiovascular disease risk ≥10%).

  • Off Label Use of Nicardipine (Cardene) in Adults:

    • Arterial hypertension in acute ischemic stroke.
    • Control of blood pressure in patients with spontaneous intracranial hemorrhage.
    • Perioperative hypertension.
    • Subarachnoid hemorrhage associated cerebral vasospasm.

Nicardipine (Cardene) dosage in adults:

Note: Cardene SR has been discontinued in the US for more than 1 year.

Nicardipine (Cardene) dose for the treatment of Angina:

  • Immediate-release:

    • 20 mg per oral thrice daily.
    • usual dosage: 20 to 40 mg 3 times daily (allow ≥3 days between dose increases)

Nicardipine (Cardene) dose for the treatment of Hypertension: 

  • Immediate-release:

    • Initial oral dose of 20 mg thrice daily.
    • The usual dosage: 20 to 40 mg 3 times daily (allow ≥3 days between dose increase)
  • Sustained-release:

    • The initial dose of 30 mg b.i.d daily
    • The usual dosage: 30 to 60 mg per oral b.i.d daily

Nicardipine (Cardene) dose for the treatment of Acute hypertension:

  • An initial intravenous dose of 5 mg/hour that can be increased by 2.5 mg/hour every 5 minutes (for fast titration) to every 15 minutes (for slow titration) up to a maximum of 15 mg/hour.
  • Adjust infusion rate according to the desired response
  • Consider reduction to 3 mg/hour after response in rapid titration.
  • The infusion should be stopped if severe hypotension/tachycardia occurs.

Nicardipine (Cardene) dose for the treatment of Arterial hypertension in acute ischemic stroke (off-label use):

  • In patients eligible for reperfusion treatment  except BP >185/110 mm Hg start intravenous dose 5 mg/hour, titrate by 2.5 mg/hour at 5- to 15-minute intervals (maximum dose: 15 mg/hour).
  • If BP still remains >185/110 mm Hg, alteplase should not be given.
  • Management of BP during and after reperfusion treatment to maintain BP ≤180/105 mm Hg:

    • If systolic BP >180 to 230 mm Hg or diastolic >105 to 120 mm Hg start with 5 mg/hour titrate by 2.5 mg/hour at 5- to 15-minute intervals
    • (maximum dose: 15 mg/hour).
    • If hypertension is refractory or diastolic BP >140 mm Hg, consider other intravenous antihypertensives (eg, nitroprusside).
  • Substitution for oral therapy (approximate equivalents):

    • 30 mg every 8 hours oral, equivalent to 1.2 mg/hour intravenous infusion
    • 40 mg every 8 hours oral, equivalent to 2.2 mg/hour intravenous infusion
  • Conversion to oral antihypertensive agent:

    • Oral antihypertensive should be started once that intravenous nicardipine is stopped.

    • Target blood pressure <130/80 mm Hg is recommended.
  • Confirmed hypertension without markers of increased ASCVD risk:

    • Target blood pressure <130/80 mm Hg may be reasonable.
  • Diabetes and hypertension: The American Diabetes Association (ADA) guidelines (ADA 2019):

    • Patients 18-65 years without atherosclerotic disease and 10-year risk <15%:

      • Target blood pressure <140/90 mm Hg is recommended
    • Patients 18-65 years  and having atherosclerotic disease or 10-year ASCVD risk >15%:

      • Target blood pressure <130/80 mm Hg is advised.
    • Patients >65 years of age (healthy):

      • Target blood pressure <140/90 mm Hg is recommended
    • Patients >65 years of age (poor health):

      • Target blood pressure <150/90 mm Hg is recommended

How to administer Nicardipine (Cardene)?

  • The total oral daily dose of the immediate-release product differs from the daily sustained-release dose therefore caution should be exercised during conversion.
  • It can be taken without regard to meals, although sustained release if given with meal may decrease the fluctuation in plasma levels.
  • The tablet should not be chewed or crushed but swallowed as a whole. Do not open or cut capsules.
  • Intravenous preparation is given as a slow continuous infusion via central line/large peripheral vein. 
  • By changing the site of infusion every 12 hours, peripheral venous irritation can be prevented.

Premixed bags:

  • Do not combine or run in the same line with other medications. 

Mechanism of action of Nicardipine (Cardene):

  • It causes calcium ion to be blocked from entering "slow channels" and voltage-sensitive areas in the vascular smooth muscles and myocardium during depolarization.
  • This results in relaxation of the coronary vascular smooth muscles and coronary vasodilation. Patients with vasospastic gina have a higher rate of myocardial oxygen delivery.

The onset of action:

  • Intravenous infusion is effective within minutes.
  • Oral: 0.5 to 2 hours

Peak effect:

  • Immediate capsules: 1 to 2 hours
  • Sustained-release capsules (at steady state): Sustained from 2 to 6 hours post-dose
  • Intravenous continuous infusion: 50% of the maximum effect is seen by 45 minutes

Duration:

  • Intravenous ≤8 hours upon discontinuation of continuous infusion, a 50% decrease in effect is seen in half an hour with gradual discontinuing antihypertensive effects for ~50 hours
  • Oral: Immediate release: ≤8 hours
  • Sustained-release: 8 to 12 hours

Absorption:

  • Oral: ~100%, but large first-pass effect

Protein binding:

  • >95%

Metabolism:

  • Occurs in the liver, extensive first-pass effect (saturable) The major pathway is via cytochrome P450 isoenzyme CYP3A4, 2C8, and 2D6.

Bioavailability:

  • Oral: ~35%

Half-life elimination:

  • Follows dose-dependent (nonlinear) pharmacokinetics; “apparent” or calculated half-life is dependent upon serum concentrations.
  • Oral: Half-life over the first 8 hours is 2 to 4 hours; terminal half-life: 8.6 hours.
  • Serum concentrations decrease tri-exponentially after intravenous infusion; alpha half-life: 3 minutes; beta half-life: 45 minutes; terminal half-life: 14 hours
  • Note: Terminal half-life can only be seen after long-term infusions).

Time to peak, serum: Oral:

  • Immediate release: 30 to 120 minutes (mean: 1 hour)
  • Sustained release: 60 to 240 minutes

Excretion:

  • Urine (oral: 60% as metabolites; IV: 49% as metabolites; <1% as unchanged drug)
  • feces (oral: 35%; IV: 43%)
  • Clearance: Decreased in patients with liver impairment; may be decreased in patients with renal impairment
