Introduction

Calcium-channel blocking agent; dihydropyridine derivative.284 307 342 343

Uses for Nifedipine

Angina

Management of Prinzmetal variant angina and chronic stable angina.a

A drug of choice for the management of Prinzmetal variant angina (used alone or in combination with nitrates).1100

β-Blockers are recommended as the anti-ischemic drugs of choice in most patients with chronic stable angina; calcium-channel blockers may be substituted or added in patients who do not tolerate or respond adequately to β-blockers.1101

Also has been used in patients with unstable angina† [off-label]; however, nondihydropyridine calcium-channel blockers (e.g., diltiazem, verapamil) generally recommended.1100

The potential risks of short-acting (conventional, immediate-release) nifedipine should be considered.242

Hypertension

Management of hypertension, alone or in combination with other classes of antihypertensive agents.126 309 342 343 344 345 348 351 1200

Only extended-release formulations currently are recommended for management of hypertension.121 126 178 181 183 184 191 192 193 197 201 202 204 205 206 207 208 209 210 211 212 213 225 226 264 309 342 344 348 1200 (See Cautions.)

Calcium-channel blockers are recommended as one of several preferred agents for the initial management of hypertension according to current evidence-based hypertension guidelines; other preferred options include ACE inhibitors, angiotensin II receptor antagonists, and thiazide diuretics.501 502 503 504 1200 While there may be individual differences with respect to recommendations for initial drug selection and use in specific patient populations, current evidence indicates that these antihypertensive drug classes all generally produce comparable effects on overall mortality and cardiovascular, cerebrovascular, and renal outcomes.501 502 503 504 1200 1213

Individualize choice of therapy; consider patient characteristics (e.g., age, ethnicity/race, comorbidities, cardiovascular risk) as well as drug-related factors (e.g., ease of administration, availability, adverse effects, cost).501 502 503 504 515 1200 1201

A 2017 ACC/AHA multidisciplinary hypertension guideline classifies BP in adults into 4 categories: normal, elevated, stage 1 hypertension, and stage 2 hypertension.1200 (See Table 1.)

Source: Whelton PK, Carey RM, Aronow WS et al. 2017 ACC/AHA/AAPA/ABC/ACPM/AGS/APhA/ASH/ASPC/NMA/PCNA guideline for the prevention, detection, evaluation, and management of high blood pressure in adults: a report of the American College of Cardiology/American Heart Association Task Force on Clinical Practice Guidelines. Hypertension. 2018;71:e13-115.

Individuals with SBP and DBP in 2 different categories (e.g., elevated SBP and normal DBP) should be designated as being in the higher BP category (i.e., elevated BP).

The goal of hypertension management and prevention is to achieve and maintain optimal control of BP.1200 However, the BP thresholds used to define hypertension, the optimum BP threshold at which to initiate antihypertensive drug therapy, and the ideal target BP values remain controversial.501 503 504 505 506 507 508 515 523 526 530 1200 1201 1207 1209 1222 1223 1229

The 2017 ACC/AHA hypertension guideline generally recommends a target BP goal (i.e., BP to achieve with drug therapy and/or nonpharmacologic intervention) <130/80 mm Hg in all adults regardless of comorbidities or level of atherosclerotic cardiovascular disease (ASCVD) risk.1200 In addition, an SBP goal of <130 mm Hg generally is recommended for noninstitutionalized ambulatory patients ≥65 years of age with an average SBP of ≥130 mm Hg.1200 These BP goals are based upon clinical studies demonstrating continuing reduction of cardiovascular risk at progressively lower levels of SBP.1200 1202 1210

Previous hypertension guidelines generally have based target BP goals on age and comorbidities.501 504 536 Guidelines such as those issued by the JNC 8 expert panel generally have targeted a BP goal of <140/90 mm Hg regardless of cardiovascular risk, and have used higher BP thresholds and target BPs in elderly patients501 504 compared with those recommended by the 2017 ACC/AHA hypertension guideline.1200

Some clinicians continue to support previous target BPs recommended by JNC 8 due to concerns about the lack of generalizability of data from some clinical trials (e.g., SPRINT study) used to support the 2017 ACC/AHA hypertension guideline and potential harms (e.g., adverse drug effects, costs of therapy) versus benefits of BP lowering in patients at lower risk of cardiovascular disease.1222 1223 1224 1229

Consider potential benefits of hypertension management and drug cost, adverse effects, and risks associated with the use of multiple antihypertensive drugs when deciding a patient’s BP treatment goal.1200 1220 1229

For decisions regarding when to initiate drug therapy (BP threshold), the 2017 ACC/AHA hypertension guideline incorporates underlying cardiovascular risk factors.1200 1207 ASCVD risk assessment recommended by ACC/AHA for all adults with hypertension.1200

ACC/AHA currently recommend initiation of antihypertensive drug therapy in addition to lifestyle/behavioral modifications at an SBP ≥140 mm Hg or DBP ≥90 mm Hg in adults who have no history of cardiovascular disease (i.e., primary prevention) and a low ASCVD risk (10-year risk <10%).1200

For secondary prevention in adults with known cardiovascular disease or for primary prevention in those at higher risk for ASCVD (10-year risk ≥10%), ACC/AHA recommend initiation of antihypertensive drug therapy at an average SBP ≥130 mm Hg or an average DBP ≥80 mm Hg.1200

Adults with hypertension and diabetes mellitus, chronic kidney disease (CKD), or age ≥65 years of age are assumed to be at high risk for cardiovascular disease; ACC/AHA state that such patients should have antihypertensive drug therapy initiated at a BP ≥130/80 mm Hg.1200 Individualize drug therapy in patients with hypertension and underlying cardiovascular or other risk factors.502 1200

In stage 1 hypertension, experts state that it is reasonable to initiate drug therapy using the stepped-care approach in which one drug is initiated and titrated and other drugs are added sequentially to achieve the target BP.1200 Initiation of antihypertensive therapy with 2 first-line agents from different pharmacologic classes recommended in adults with stage 2 hypertension and average BP >20/10 mm Hg above BP goal.1200

Calcium-channel blockers may be preferred in hypertensive patients with certain coexisting conditions (e.g., ischemic heart disease)171 185 187 192 198 523 and in geriatric patients, including those with isolated systolic hypertension.181 183 220 221 222 227 502 510

Black hypertensive patients generally respond better to monotherapy with calcium-channel blockers or thiazide diuretics than to other antihypertensive drug classes (e.g., ACE inhibitors, angiotensin II receptor antagonists).501 504 1200 However, the combination of an ACE inhibitor or an angiotensin II receptor antagonist with a calcium-channel blocker or thiazide diuretic produces similar BP lowering in black patients as in other racial groups.1200

Nifedipine is not recommended for management of hypertensive crises.283 284 295 307 338 339 340 341

Nifedipine is recommended by ACOG and other experts as an appropriate drug of choice in pregnant women who require antihypertensive therapy.388 540

Raynaud’s Phenomenon

Drug of choice for the management of Raynaud’s phenomenon† [off-label],144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 296 297 298 305 306 preferably administered as extended-release formulations.296 297 305 306

Preterm Labor

Has been used in selected women to inhibit uterine contractions in preterm labor† [off-label] (tocolysis) and prolong gestation when beneficial.290 291 292 293 294 389

ACOG states that because of conflicting results, there is no clear first-line tocolytic agent;389 data from randomized, controlled studies suggest calcium-channel blockers (principally nifedipine) may be more effective than, and preferable to, other agents (e.g., magnesium sulfate, β-adrenergic agonists).390

Main benefit currently derived from tocolytic therapy may be to forestall labor providing time for patients to receive corticosteroids to increase fetal lung maturation and/or be transferred to other (e.g., tertiary-care) facilities; any other potential benefits of prolonging pregnancy are unclear.290 291 293 294 389 390 419 420 421

Acute MI

Used in the early treatment and secondary prevention of acute MI† [off-label]; an effective anti-ischemic agent, but mortality benefit not demonstrated.266 527 1100

Calcium-channel blockers generally are used for their anti-ischemic and BP-reducing properties in the MI setting, and only when β-blockers (which have been shown to reduce mortality after MI) are ineffective, not tolerated, or contraindicated.527 702 1100

Experts state that calcium-channel blockers may be used to relieve ischemic symptoms, lower BP, or control rapid ventricular response rate associated with atrial fibrillation in patients with ST-segment-elevation MI (STEMI) who are intolerant to β-blockers.527

Experts recommend a nondihydropyridine calcium-channel blocker for ongoing or recurrent ischemia in patients with non-ST-segment-elevation MI (NSTEMI) who have a contraindication to β-blockers and who do not have clinically important left ventricular dysfunction, increased risk of cardiogenic shock, or AV block.1100

Use of immediate-release nifedipine generally contraindicated because of possible hypotension and reflex sympathetic activation.527 1100

Nifedipine Dosage and Administration

General

BP Monitoring and Treatment Goals

Administration

Oral Administration

Conventional Capsules

Administer capsules orally 3 times daily.284

Swallow capsules whole.284

Extended-release Tablets

Administer orally once daily.126 342

Extended-release tablets should be swallowed intact and should not be chewed, crushed, or broken.126 342

Manufacturer recommends that Adalat CC be administered on an empty stomach.342

The shell of the extended-release tablet does not dissolve and may be passed in the stool.342 343

Whenever extended-release tablets are dispensed or administered, care should be taken to ensure that the extended-release dosage form actually was prescribed.126

Dosage of extended-release nifedipine tablets should be decreased gradually with close clinical supervision when discontinuance of the drug is required.126 342

Dosage

Manufacturer states that two 30-mg Adalat CC extended-release tablets may be interchanged with one 60-mg Adalat CC extended-release tablet; however, three 30-mg Adalat CC extended-release tablets should not be considered interchangeable with one 90-mg Adalat CC extended-release tablet.342

Pediatric Patients

Hypertension† [off-label]
Extended-release Tablets
Oral

Initially, 0.2–0.5 mg/kg daily given in 1 dose or 2 divided doses recommended by some experts.1150 Initiate drug at the low end of the dosage range; may increase dosage every 2–4 weeks until BP controlled, maximum dosage reached (3 mg/kg [up to 120 mg] daily, given in 1 or 2 divided doses), or adverse effects occur.1150

Adults

Angina
Conventional Capsules
Oral

Initially, 10 mg 3 times daily.284 307

Increase dosage gradually at 7- to 14-day intervals until optimum control of angina is obtained.a

May increase more rapidly to 90 mg daily in increments of 30 mg daily over a 3-day period if symptoms so warrant and patient’s tolerance and response to therapy are frequently assessed.284 307

In hospitalized patients who are closely monitored, dosage may be increased in 10-mg increments at 4- to 6-hour intervals, as necessary to control pain and arrhythmias caused by ischemia.284 307 Single doses usually should not exceed 30 mg.284 307

Some experts state usual maintenance dosage is 10–20 mg 3 times daily.a In some patients, especially those with evidence of coronary artery spasm, increased dosages of 20–30 mg 3 or 4 times daily and rarely, more than 120 mg daily may be necessary.a

Extended-release Tablets
Oral

Initially, 30 or 60 mg once daily.126

Increase dosage gradually at 7- to 14-day intervals until optimum control of angina is obtained.a

Dosage may be increased more rapidly to 90 mg daily in increments of 30 mg daily after steady state is achieved (usually achieved on the second day of therapy with a given dose) if symptoms so warrant and patient’s tolerance and response are frequently assessed.126

In some patients, especially those with evidence of coronary artery spasm, higher dosages may be necessary.a However, experience with antianginal dosages exceeding 90 mg once daily as extended-release tablets is limited and should be employed with caution and only when clinically necessary.126

Extended-release tablets can be substituted for the conventional capsules at the nearest equivalent total daily dose.126

Contraindications

Warnings/Precautions

Warnings

Excessive Hypotension

Risk of excessive, poorly tolerated hypotension in patients being treated for angina; usually occurs during initial dosage titration or subsequent upward titration and may be more likely in patients receiving concomitant β-blocker.114 126 129 284 286 307 Carefully monitor BP, especially during therapy initiation, titration, or dosage increase.126 284 342 a

Cardiovascular Effects with Conventional Preparations

Conventional (immediate-release) nifedipine formulations generally are contraindicated in the routine management of acute MI because of negative inotropic effects and reflex sympathetic activation, tachycardia, and hypotension associated with its use.242 284 307 527 Do not administer within first 1–2 weeks after MI and avoid in acute coronary syndrome when infarction may be imminent.284 307

Risk of profound hypotension, cerebrovascular ischemia or stroke, myocardial ischemia or infarction, and/or death with use of conventional preparations for management of hypertensive crises;119 283 284 288 295 300 302 303 304 307 308 similar effects reported in patients receiving such preparations for angina or pulmonary hypertension.283 286 287 310 Do not use short-acting preparations for acute BP reduction or for chronic hypertension management.284 307

Increased Angina and/or Acute MI

Rarely, increased frequency, duration, and/or severity of angina or acute MI, particularly in patients with severe obstructive CAD, upon initiation or dosage increase of calcium-channel blockers.126 284 342

β-Blocker Withdrawal

Possible increased angina in patients recently withdrawn from β-blockers after nifedipine initiation.126 284 342 Taper dosage of β-blockers before initiation of nifedipine.126 284 342 (See Interactions.)

Nifedipine drug interactions (more detail)

Nifedipine Pharmacokinetics

Absorption

Bioavailability

Following oral administration of conventional capsules, approximately 90% of a dose is absorbed with peak serum concentrations usually attained within 0.5–2 hours.a

Oral bioavailability of extended-release tablets is approximately 75–89% of that achieved with same doses as conventional capsules.126 130 342

Peak plasma concentrations for extended-release tablets are attained within about 2.5–6 hours.130 342

Food

Food decreases the rate but not extent of absorption from conventional capsules.140

Food can increase the early rate of GI absorption of extended-release tablets but does not affect overall bioavailability.126 342

Special Populations

Bioavailability is increased in patients with liver cirrhosis126 132 133 284 307 342 and may be particularly increased in those with portacaval shunts.132

Following oral administration of extended-release tablets (Adalat CC), , absorption of nifedipine may be altered in patients with renal impairment.342

Substantial reductions in GI retention time for prolonged periods (e.g., in patients with short-bowel syndrome) can result in decreased absorption from extended-release tablets.126

Increased mean peak plasma concentrations and average plasma concentrations compared with those in younger adults have been reported in healthy subjects >60 years of age receiving Adalat CC extended-release tablets.342

Distribution

Extent

Nifedipine is distributed into milk.165

Plasma Protein Binding

Approximately 92–98%.126 284

Special Populations

Plasma protein binding may be decreased in patients with renal126 133 139 284 307 342 or hepatic126 132 133 284 307 342 impairment.

Elimination

Metabolism

Extensively metabolized in the liver by CYP isoenzymes, including CYP3A, to highly water soluble, inactive metabolites.126 284 342 a

Elimination Route

Metabolites excreted in urine (60–80%) and feces (possibly via biliary elimination).126 342 a

Half-life

2 hours (conventional capsules); 7 hours (Adalat CC extended-release tablets).126 284 342 a

Special Populations

Elimination may be altered in patients with hepatic impairment.126 132 133 284 307 342 Elimination half-life of 7 hours reported in patients with cirrhosis.132 133

Following IV administration, decreased total body clearance in geriatric individuals compared with that in young adults .342
